Token Metrics Team
7
MIN

The landscape of cryptocurrency and Web3 has evolved dramatically in recent years, offering investors an expanding array of opportunities within the digital economy. As we navigate through October 2025, with Bitcoin trading above $124,000 and the total crypto market capitalization exceeding $4.15 trillion, many investors face a critical question: should I invest in crypto or Web3 companies? The reality is that both options present compelling potential, and understanding their differences, risks, and benefits is essential for making an informed investment decision.

Introduction to Web3 and Crypto

Web3, often referred to as the decentralized web, represents the next evolution of the world wide web—one that empowers internet users with greater control, privacy, and ownership of their digital assets. Unlike traditional internet platforms controlled by centralized entities, Web3 leverages blockchain technology to create decentralized networks and applications. This shift enables users to interact, transact, and store digital assets in a more secure and transparent environment.

At the core of the Web3 movement is the crypto ecosystem, which includes a wide range of crypto assets such as cryptocurrencies and non-fungible tokens (NFTs). Built on blockchain technology, these digital assets facilitate peer-to-peer transactions without intermediaries. As internet users seek innovative investment options, decentralized apps and networks are gaining popularity for their ability to offer new ways to invest, earn, and participate in the digital economy.

History and Evolution

The journey of Web3 began in 2014 when Gavin Wood, co-founder of Ethereum, introduced the concept as a vision for a more open and user-centric internet. Since then, the decentralized ecosystem has experienced rapid growth, fueled by blockchain technology and the emergence of unique digital assets. This foundation has enabled the development of decentralized applications (dApps) and new investment avenues previously unimaginable.

Recently, focus has shifted from centralized platforms to decentralized networks, giving users unprecedented control over data and assets. For example, decentralized finance (DeFi) has revolutionized crypto asset investment, offering innovative technologies that bypass traditional financial intermediaries. This progression has expanded investment opportunities and empowered users to participate directly in the digital economy.

Understanding the Ecosystem

Navigating the Web3 ecosystem requires a clear understanding of its main components, including digital currencies, dApps, and blockchain networks. For investors entering crypto, it’s vital to recognize that the ecosystem is multifaceted and constantly evolving. Digital assets range from established cryptocurrencies to innovative tokens powering decentralized platforms.

Conducting thorough research and staying updated on emerging trends are crucial for effective investment outcomes. Artificial intelligence increasingly supports Web3 projects by validating transactions, enhancing security, and improving user experience across platforms. Understanding how these technologies interact within the broader crypto ecosystem allows investors to make more informed decisions and capitalize on new opportunities.

Understanding the Current Investment Landscape

The crypto market has matured significantly, demonstrating institutional adoption, clearer regulations, and sustained growth. Bitcoin recently surpassed $120,000, driven by institutional interest through ETFs and macroeconomic factors. Ethereum’s performance also exhibited resilience, climbing from around $3,500 to over $4,200 in Q3 2025.

Meanwhile, the Web3 sector—including blockchain infrastructure, dApps, and internet tech—has grown impressively. By mid-2025, market capitalization of Web3 companies exceeded $62.19 billion, with forecasts surpassing $65 billion by 2032. This parallel expansion indicates robust opportunities in both cryptocurrencies and Web3 companies, enhancing the appeal of diversified investment approaches.

The Case for Direct Cryptocurrency Investment

Investing directly in cryptocurrencies provides exposure to digital assets lacking intermediary fees or corporate overhead. Buying tokens like Bitcoin or Ethereum offers potential for price appreciation and control over assets secured in digital wallets.

Cryptocurrency exchanges serve as primary platforms, ensuring liquidity and security. Current forecasts anticipate Bitcoin trading in the range of $80,440 to $151,200 in 2025, supported by institutional interest from firms like BlackRock and Fidelity. Crypto markets operate 24/7, enabling rapid responses to market shifts.

The growing Web3 crypto job market, which surged 300% from 2023 to 2025, reflects real economic activity. Platforms like Token Metrics support this approach by providing AI-powered analytics, real-time data, and integrated trading tools—making digital asset research and management more accessible for investors.

The Case for Web3 Company Investment

Investing in Web3 companies involves acquiring equity in firms developing infrastructure and platforms for the decentralized web. Instead of holding tokens, investors gain exposure through stocks like Coinbase, valued at nearly $58 billion, which has appreciated over 313% in the past year.

Technology giants such as Nvidia, with a market cap above $3 trillion, benefit from Web3 growth through computing hardware critical for blockchain mining and AI. Web3 stocks often offer diversification within the tech sector. ETFs focusing on Web3 companies provide diversified exposure without selecting individual stocks, though single-stock risks remain.

Regulatory Considerations: A Turning Point

The regulatory landscape has become more favorable for cryptocurrencies and Web3 firms, with bipartisan support in Congress and new legislation like the GENIUS Act of July 2025 establishing clearer rules for stablecoins and digital assets. This clarity fosters a more secure environment for investments, building confidence in the industry’s longevity and sustainability.

Risk Considerations and Portfolio Strategy

Investments in crypto and Web3 stocks carry distinct risks. Crypto assets face high volatility, security challenges with wallets, and technical complexities. Effective security practices, device management, and continuous research are essential to mitigate these risks.

Web3 stock investments involve considerations such as market execution risk, competition, and broader economic fluctuations. A blended portfolio—including both digital assets and equities—can optimize potential returns while diversifying risks.

Platforms like Token Metrics offer tools for risk management, including automation, analytics, and portfolio monitoring—helping investors navigate volatility with data-driven insights.

Emerging Opportunities: DeFi, Gaming, and Tokenization

The Web3 landscape is expanding with decentralized finance (DeFi), gaming, and tokenization. DeFi enables lending, borrowing, and trading without intermediaries, while Web3 gaming has seen a 60% rise in active users. The tokenization market, representing real-world assets on blockchain, has grown by about 23%, creating new investment niches in art, real estate, and securities.

Success Stories

Bitcoin’s growth from a niche experiment to a trillion-dollar asset exemplifies the decentralized financial revolution. Ethereum has facilitated the development of smart contracts and dApps, fueling innovation in multiple sectors. NFTs have revolutionized digital ownership, empowering artists and creators to monetize unique digital assets. These success stories highlight the evolving potential and inherent risks of investing in decentralized assets.

Making Your Investment Decision

Choosing between crypto and Web3 stocks depends on your investment timeline, risk tolerance, technical knowledge, and goals. Cryptocurrencies may offer faster appreciation but demand active management; stocks tend to provide steadier, long-term growth. A diversified approach combining both strategies can help balance potential upside with risk management.

Investment Tips

  • Conduct thorough research before investing—understand the technology, team, and use case.
  • Diversify across assets and platforms to reduce risk.
  • Set a clear budget and only invest what you can afford to lose.
  • Explore DeFi and other emerging technologies for additional opportunities.
  • Stay informed on latest trends and regulatory developments to make timely decisions.

The Bottom Line

In 2025, both cryptocurrencies and Web3 company stocks present significant opportunities within the growing digital economy. Market maturation, clearer regulations, and technological advances support sustained growth. A diversified portfolio, combined with advanced tools like Token Metrics, can help investors navigate this complex landscape effectively. As the Web3 ecosystem continues to expand, the key question shifts from whether to invest into how to do so wisely to maximize opportunities and manage risks in this evolving digital frontier.

How Do I Calculate Capital Gains on Crypto: Complete 2025 Tax Guide

Token Metrics Team
13
MIN

As cryptocurrency becomes increasingly mainstream, knowing how do I calculate capital gains on crypto is essential for every investor. The IRS treats cryptocurrency as property rather than currency, meaning each trade, sale, or purchase of crypto triggers a taxable event that must be carefully documented. This means that cryptocurrency is taxed similarly to other forms of property, with gains and losses reported for each transaction. This article serves as a comprehensive crypto tax guide, helping you understand how to accurately calculate your crypto capital gains so you can manage your tax bill effectively and avoid costly compliance issues.

Understanding Crypto Capital Gains Basics

Capital gains on cryptocurrency arise when you sell, trade, or spend your crypto for more than you originally paid. At its core, the calculation is straightforward: your proceeds (sale price) minus your cost basis (purchase price) equals your capital gain or loss. These gains are subject to crypto capital gains tax. However, the reality is far more complex, especially for active traders who manage multiple positions across various exchanges and wallets.

The IRS distinguishes between short-term capital gains and long-term capital gains based on how long you hold your crypto assets. If you hold your cryptocurrency for one year or less, any gains are considered short-term and taxed at your ordinary income tax rates, which range from 10% to 37% depending on your total taxable income. Conversely, assets held for more than one year qualify for preferential long-term capital gains tax rates of 0%, 15%, or 20%, based on your income and filing status. How crypto is taxed depends on the holding period and whether the gain is classified as short-term or long-term, so understanding how crypto taxed applies to your transactions is essential. This distinction can create significant tax planning opportunities for investors who strategically time their sales.

The Capital Gains Calculation Formula

To calculate crypto capital gains accurately, you need three critical pieces of information for each transaction: your cost basis, your proceeds, and your holding period. Your cost basis is the original purchase price of your crypto, including any transaction fees directly related to the purchase. Proceeds are the amount you receive when you dispose of the crypto, minus any fees related to the sale. The difference between your proceeds and cost basis is your taxable gain, which is the amount subject to capital gains tax.

For example, imagine you bought 1 Bitcoin in June 2024 for $70,000 and sold it four months later for $80,000. Your capital gain is $80,000 minus $70,000, or $10,000. This $10,000 is your taxable gain and must be reported for bitcoin taxes. Since you held the Bitcoin for less than a year, this gain is short-term and taxed at your ordinary income tax rate. If your annual income is $85,000, your total taxable income becomes $95,000, placing you in the 24% federal tax bracket for 2024. This means you owe approximately $2,400 in federal taxes on that gain.

If you instead held the Bitcoin for 13 months before selling, the $10,000 gain qualifies for long-term capital gains treatment. With the same income, your tax rate on the gain would be 15%, resulting in a $1,500 tax bill—a $900 savings just by holding the asset longer.

Why Crypto Tax Calculations Get Complicated

While the basic formula seems simple, real-world crypto investing introduces many complexities. Take Sarah, an investor who bought Bitcoin at various prices: $5,000, $10,000, $15,000, and $20,000. When she sells part of her holdings, which purchase price should she use to calculate her cost basis?

This question highlights the importance of selecting a cost basis method. The IRS permits several approaches: FIFO (First In, First Out) uses the oldest purchase price; LIFO (Last In, First Out) uses the most recent purchase price; and HIFO (Highest In, First Out) uses the highest purchase price to minimize gains. These are all different cost basis methods, and the accounting method you choose can significantly affect your tax liability.

Complications also arise from trading on multiple exchanges and moving crypto between different wallets. Most investors don’t stick to one platform—they might buy on Coinbase, trade on Binance, stake on other platforms, and transfer assets between wallets. Each platform maintains separate transaction records, and consolidating these into a complete transaction history is like assembling a complex puzzle. Tracking your crypto cost basis for each asset is crucial, especially when dealing with multiple transactions across different platforms.

Taxable Events Beyond Simple Sales

Calculating capital gains on crypto involves more than just selling for fiat currency. Several other actions involving digital assets are considered taxable events from a tax perspective, each representing a type of crypto transaction:

  • Trading one cryptocurrency for another (e.g., swapping Bitcoin for Ethereum) is a crypto trade and triggers capital gains taxes, requiring you to calculate gains on the disposed digital asset.
  • Selling crypto for fiat currency is a crypto transaction that counts as a disposal event. For tax purposes, you must calculate the difference between your cost basis and the fair market value of the digital asset at the time of the transaction.
  • Spending crypto on goods or services is another form of crypto transaction and counts as a disposal. You must calculate the difference between your cost basis and the fair market value at the time of the transaction.
  • Receiving cryptocurrency as crypto income—from mining rewards, staking, airdrops, or employment compensation—creates ordinary income taxable at your income tax rate. The fair market value at receipt establishes your cost basis for future capital gains calculations.

You owe capital gains tax whenever you dispose of or convert digital assets through these types of crypto transactions. The tax treatment of each event depends on the nature of the transaction, and the IRS provides specific guidance on how to report and classify these activities.

Not all crypto activities generate taxable events. Simply buying and holding digital assets doesn’t trigger a tax bill until you dispose of them. Transferring crypto between your own wallets is also non-taxable, though keeping detailed records of these crypto transactions is vital to track your cost basis accurately. Additionally, gifting crypto under the annual gift tax exclusion (set at $19,000 per recipient for 2025) doesn’t create taxable gains for the giver, but the recipient inherits the giver's cost basis (the original purchase price and acquisition date) for tax purposes. Proper documentation of the giver's cost basis is important for future tax reporting. The tax treatment of gifts and other crypto transactions should always be considered from a tax perspective to ensure compliance.

Crypto Income and Tax Implications

Crypto income encompasses a range of earnings from activities like mining, staking, airdrops, and earning interest through crypto lending platforms. For tax purposes, the IRS treats all these forms of crypto income as ordinary income, meaning they are taxed at your regular income tax rates based on your total taxable income. The key factor in determining your tax bill is the fair market value of the crypto assets at the time you receive them. For example, if you receive $1,000 worth of Bitcoin as a mining reward, you must report that $1,000 as taxable income on your tax return for the year.

Accurate reporting of crypto income starts with maintaining a complete transaction history. You should record the date, time, amount, and fair market value of each crypto asset received. This information is essential for calculating your tax liability and ensuring your tax return is accurate. Using tax software or a crypto tax calculator can greatly simplify this process by automatically importing your transaction data from exchanges and wallets, calculating your gains and losses, and generating a comprehensive tax report.

Beyond mining and staking rewards, other types of crypto income—such as interest from lending platforms or profits from trading—are also subject to crypto tax. Each of these activities can have unique tax implications, so it’s wise to consult a tax professional or use specialized tax software to ensure you’re following IRS rules and reporting all taxable income correctly. By understanding how crypto income is taxed and taking steps to accurately calculate and report it, you can avoid unexpected tax bills and minimize your overall tax liability.

Leveraging Token Metrics for Accurate Tracking

Given the complexities of calculating crypto capital gains across multiple exchanges, wallets, and hundreds of transactions, having robust tracking tools is essential. This is where Token Metrics, a leading crypto trading and analytics platform, comes into play.

Token Metrics provides comprehensive portfolio tracking by aggregating your positions across exchanges and wallets, giving you real-time visibility into your entire crypto portfolio. This unified view simplifies the daunting task of compiling transaction records from disparate sources—a critical first step in accurate tax calculation. Organizing your transactions by tax year is essential for proper reporting and ensures you meet IRS deadlines for each tax year.

Beyond tracking, Token Metrics offers advanced analytics that empower investors to make tax-efficient trading decisions year-round, rather than scrambling during tax season. By understanding your current cost basis, holding periods, and potential tax implications before executing trades, you can optimize timing to minimize your tax liability. The platform’s insights help you plan around the one-year holding period that distinguishes short-term from long-term capital gains rates.

For active traders with complex portfolios, Token Metrics provides detailed performance attribution and reconstructs your cost basis accurately. Its reporting features generate comprehensive documentation to support your tax calculations, which is crucial for IRS compliance and audit defense. Token Metrics helps users report crypto transactions accurately and assists in reporting crypto gains for tax compliance, making it easier to meet regulatory requirements.

Token Metrics also aids in identifying opportunities for tax-loss harvesting, a strategy where you sell depreciated assets to realize losses that offset capital gains. By clearly showing which positions are underwater and by how much, the platform enables strategic loss realization that reduces your overall tax bill while maintaining your desired market exposure. Tools like Token Metrics are invaluable for managing cryptocurrency taxes and streamlining the entire tax preparation process.

Resolving Missing Cost Basis

Missing cost basis is a common challenge for crypto investors, especially those who have been active in the market for several years or have moved assets between multiple wallets and exchanges. The cost basis is the original purchase price of your crypto asset, including any transaction fees. Without this information, it becomes difficult to accurately calculate your capital gains or losses when you sell, trade, or otherwise dispose of your crypto.

To resolve missing cost basis, start by gathering as much information as possible about the original transaction. Check your exchange records, wallet transaction histories, and any other documentation that might indicate the purchase price, date, and amount of the crypto asset. If you’re unable to locate the original purchase price, some tax software can help estimate your cost basis based on available transaction records. However, using an estimated cost basis can be risky, as the IRS may scrutinize these calculations during an audit.

Maintaining accurate and complete transaction records is the best way to avoid missing cost basis issues in the future. Tax software like Token Metrics can help you track and calculate cost basis for each crypto asset, generate a detailed tax report, and ensure you’re prepared for tax season. If you’re unsure about how to calculate cost basis or need to estimate it due to missing information, consulting a tax professional is highly recommended. By resolving missing cost basis issues and keeping thorough records, you can accurately calculate your capital gains, comply with IRS rules, and minimize your tax liability.

Tax-Loss Harvesting and Strategic Planning

There are a few strategies you can use to reduce your tax bill when dealing with cryptocurrency. These include tax-loss harvesting, holding assets for long-term gains, and careful planning of your transactions.

Capital losses can be a powerful tool for managing your tax bill. You can use capital losses to offset capital gains dollar-for-dollar, lowering your taxable income. If your losses exceed your gains, you can deduct up to $3,000 of net capital loss against ordinary income each year, with remaining losses carrying forward to future tax years.

Savvy investors practice tax-loss harvesting throughout the year, especially during market downturns. This approach is similar to strategies used for traditional investments like stocks. By selling depreciated positions to realize losses, they generate tax deductions and may repurchase similar assets to maintain exposure. It’s important to note that the IRS wash sale rule, which disallows losses on securities repurchased within 30 days, currently does not apply to cryptocurrency, though proposed regulations could change this.

You are required to pay taxes on gains from crypto activities, including trading, selling, or spending your crypto. Holding crypto for over a year before selling can substantially reduce your tax liability. The difference between ordinary income tax rates (up to 37%) and long-term capital gains rates (max 20%) can save tens of thousands of dollars on large gains. Patient investors who plan their sales strategically can significantly lower their tax liability.

If you mine cryptocurrency or operate as a self-employed individual, you may also be subject to self employment tax, which includes social security contributions, in addition to income and capital gains taxes.

Record Keeping and Reporting Requirements

Starting in 2025, cryptocurrency exchanges are required to report your transactions and wallet addresses directly to the IRS, making meticulous record keeping for all your digital assets more important than ever. You must maintain detailed documentation including transaction dates, amounts, fair market values at transaction time, involved parties, and the purpose of each transaction.

For tax reporting, you’ll use IRS Form 8949 to report your capital gains and losses, transferring totals to Schedule D. Income from mining, staking, or business activities, such as operating a crypto mining business, is reported on Schedule 1 or Schedule C. Due to the complexity of these forms, many investors rely on tax preparation software or consult a tax professional to ensure accuracy.

Platforms like Token Metrics simplify this process by maintaining a complete transaction history and providing organized reports ready for tax filing. Instead of manually reconstructing hundreds or thousands of transactions from multiple exchanges and wallets, you get centralized, accurate records that streamline your tax return preparation.

State Taxes and Additional Considerations

Federal taxes are only part of your overall tax obligation. Depending on your state of residence, you may owe additional state taxes on your crypto gains. States such as California, New York, and New Jersey impose significant taxes on investment income, while others like Texas, Florida, and Nevada have no state income tax. Your total tax liability is the sum of your federal and state obligations, so it’s important to understand your local tax rules.

Conclusion

Learning how do I calculate capital gains on crypto is crucial to managing your cryptocurrency investments responsibly and minimizing your tax burden. Calculating capital gains requires understanding IRS rules, maintaining detailed records, selecting appropriate accounting methods, and planning around holding periods and loss harvesting.

The complexity of cryptocurrency taxation, especially for active traders, makes reliable analytics and reporting tools indispensable. Token Metrics offers the comprehensive tracking, analysis, and reporting capabilities you need to navigate crypto taxes confidently. Its real-time portfolio visibility, accurate cost basis calculations, and tax-efficient trading insights transform the daunting task of crypto tax compliance into a manageable process.

As IRS enforcement intensifies and cryptocurrency tax regulations evolve, having sophisticated tools and accurate data becomes more valuable than ever. Whether you’re a casual investor with a few transactions or an active trader managing complex portfolios, understanding how to calculate capital gains correctly—and leveraging platforms like Token Metrics—protects you from costly errors while optimizing your tax position.‍

What's the Safest Way to Store Large Crypto Holdings? A 2025 Security Guide

Token Metrics Team
14
MIN

As cryptocurrency portfolios grow in value, understanding what’s the safest way to store large crypto holdings becomes a critical concern for investors. In 2024 alone, over $2.2 billion was stolen through various crypto hacks and scams, highlighting the vulnerabilities in digital asset protection. These incidents reveal the significant risks associated with storing large amounts of cryptocurrency, including potential vulnerabilities and hazards that can lead to loss or theft. Recent high-profile incidents, such as Coinbase’s May 2025 cyberattack that exposed customer information, underscore the urgent need for robust crypto security measures and the importance of following the safest ways to protect your assets. Unlike traditional bank accounts that benefit from FDIC insurance and fraud protection, stolen cryptocurrency cannot be refunded or insured through conventional means. This reality makes choosing the right cryptocurrency storage method to store your cryptocurrency essential for anyone holding significant crypto assets.

Understanding the Storage Landscape: Hot vs. Cold

When it comes to crypto storage, the fundamental distinction lies in whether wallets are connected to the internet. There are different types of crypto wallets, each offering unique benefits and security features. Hot wallets are always online, making them convenient for trading, transactions, and quick access to funds. However, their constant internet connection makes them inherently vulnerable to hacking, phishing, and malware attacks. Examples include mobile, desktop, and web-based wallets, which are often used for daily spending or quick access to tokens.

On the other hand, cold wallets—also known as cold storage—store private keys completely offline. This means they are disconnected from the internet, drastically reducing the risk of remote attacks. Cold wallets are ideal for long term storage of large crypto assets, where security takes precedence over convenience. A custodial wallet is another option, where a third-party provider, such as an exchange, manages and holds your private keys on your behalf, offering convenience but less direct control compared to non-custodial wallets.

Think of hot wallets as your checking account: convenient but not meant for holding large sums. Cold wallets function like a safety deposit box, providing secure storage for assets you don’t need to access frequently. Crypto wallets use a public key as an address to receive funds, while the private key is used to sign transactions. For large holdings, experts recommend a tiered approach: keep only small amounts in hot wallets for active use, while storing the majority in cold storage. This balances security, access, and the risk of funds being compromised. Cold wallets keep private keys offline and store your private keys and digital assets securely, reducing the risk of theft.

Hardware Wallets: The Gold Standard for Individual Investors

Among cold storage options, hardware wallets are widely regarded as the safest and most practical solution for individual investors managing large cryptocurrency holdings. These physical devices, often resembling USB drives, securely store your private keys offline and only connect to the internet briefly when signing transactions.

Leading hardware wallets in 2025 include the Ledger Nano X, Ledger Flex, and Trezor Model Safe 5. These devices use secure element chips—the same technology found in credit cards and passports—to safeguard keys even if the hardware is physically compromised. By keeping private keys offline, hardware wallets protect your assets from malware, hacking, and remote theft.

To maximize safety when using hardware wallets, always purchase devices directly from manufacturers like Ledger or Trezor to avoid tampered products. When you create your wallet, securely generate and store your seed phrase or recovery phrase by writing it on paper or metal backup solutions. Another option is a paper wallet, which is a physical printout of your private and public keys, used as a form of cold storage for cryptocurrencies. Store these backups in multiple secure locations such as fireproof safes or safety deposit boxes. For example, you might keep one copy of your paper wallet or backup phrase in a home safe and another in a bank safety deposit box to reduce the risk of loss. Never store recovery phrases digitally or photograph them, as this increases the risk of theft.

Enable all available security features, including PIN protection and optional passphrases, for an extra layer of encryption. For very large holdings, consider distributing assets across multiple hardware wallets from different manufacturers to eliminate single points of failure. The main limitation of hardware wallets is their physical vulnerability: if lost or destroyed without proper backup, your funds become irretrievable, making diligent backup practices essential.

Multi-Signature Wallets: Distributed Control for Enhanced Security

For even greater protection, especially among families, businesses, and institutional investors, multi-signature (multisig) wallets provide distributed control over funds. Unlike traditional wallets that require a single private key to authorize transactions, multisig wallets require multiple keys to sign off, reducing the risk of theft or loss.

A common configuration is a 2-of-3 setup, where any two of three keys are needed to sign a transaction. In this setup, the concept of 'two keys' is fundamental—two keys must be provided to authorize and access the funds. This means that funds can only be accessed when the required number of keys are available, ensuring both redundancy and security. If one key is lost, the other two can still access funds—while maintaining strong security since an attacker would need to compromise multiple keys simultaneously. More complex configurations like 3-of-5 are common for very large holdings, allowing keys to be geographically distributed to further safeguard assets.

Popular multisig wallet providers in 2025 include BitGo, which supports over 1,100 digital assets and offers insurance coverage up to $250 million for funds stored. BitGo’s wallets combine hot and cold storage with multisig security, meeting regulatory standards for institutional clients. Other notable solutions include Gnosis Safe (now known as Safe) for Ethereum and EVM-compatible chains, and Unchained, which manages over 100,000 Bitcoin using 2-of-3 multisig vaults tailored for Bitcoin holders. While multisig wallets require more technical setup and can slow transaction processing due to the need for multiple signatures, their enhanced security makes them ideal for large holdings where protection outweighs convenience.

Multi-Party Computation: The Emerging Institutional Standard

An innovative advancement in crypto storage is Multi-Party Computation (MPC) technology, rapidly becoming the standard for institutional custody. Unlike multisig wallets where multiple full private keys exist, MPC splits a single private key into encrypted shares distributed among several parties. The full key never exists in one place—not during creation, storage, or signing—greatly reducing the risk of theft.

MPC offers advantages over traditional multisig: it works seamlessly across all blockchains, transactions appear identical to regular ones on-chain enhancing privacy, and it avoids coordination delays common in multisig setups. Leading MPC custody providers like Fireblocks have demonstrated the security benefits of this approach. However, Fireblocks also revealed vulnerabilities in competing threshold signature wallets in 2022, highlighting the importance of ongoing security audits in this evolving field.

For individual investors, MPC-based wallets like Zengo provide keyless security without requiring a seed phrase, distributing key management across secure locations. Nevertheless, MPC solutions are primarily adopted by institutions, with firms like BitGo, Fireblocks, and Copper offering comprehensive custody services for family offices and corporations.

Institutional Custody Solutions: When Professional Management Makes Sense

For extremely large holdings—often in the millions of dollars—professional institutional custody services offer unparalleled security infrastructure, insurance coverage, and regulatory compliance. These platforms typically facilitate not only secure storage but also the buying and selling of crypto assets as part of their comprehensive service offerings. Institutional custody solutions are commonly used to store bitcoin and other major cryptocurrencies securely, protecting them from theft, loss, and unauthorized access.

Regulated custodians implement multiple layers of protection. They undergo regular third-party audits and SOC certifications to verify their security controls. Many maintain extensive insurance policies covering both hot and cold storage breaches, sometimes with coverage reaching hundreds of millions of dollars. Professional key management minimizes user errors, and 24/7 security monitoring detects and responds to threats in real-time.

Despite these advantages, institutional custody carries counterparty risk. The Coinbase cyberattack in May 2025, which exposed customer personal information (though not passwords or private keys), served as a reminder that even the most secure platforms can be vulnerable. Similarly, the collapse of platforms like FTX, Celsius, and BlockFi revealed that custodial services can fail catastrophically, sometimes taking customer funds with them.

Therefore, thorough due diligence is essential when selecting institutional custodians. Verify their regulatory licenses, audit reports, insurance coverage, and operational history before entrusting significant funds.

The Critical Role of Analytics in Secure Portfolio Management

Securing large crypto holdings is not just about storage—it also involves smart portfolio management and timely decision-making. Sophisticated analytics platforms have become essential tools for this purpose. Token Metrics stands out as a leading AI-powered crypto trading and analytics platform designed to help users manage large cryptocurrency portfolios effectively.

Essential Security Practices Beyond Storage Technology

Even the most secure storage methods can fail without proper security hygiene. Regardless of your chosen storage solution, certain best practices are essential:

  • Never share your private keys or recovery phrases with anyone. Legitimate services will never ask for this information. Requests for keys are always scams.
  • Enable two-factor authentication (2FA) on all accounts using authenticator apps or hardware security keys (e.g., YubiKey) rather than SMS-based 2FA, which is vulnerable to SIM-swap attacks.
  • Use a password manager to generate and store unique, complex passwords for every exchange and wallet service, avoiding password reuse.
  • Whitelist withdrawal addresses on exchanges to restrict withdrawals to pre-approved addresses, reducing the risk of unauthorized transfers.
  • Verify transaction addresses carefully before confirming. Malware can alter clipboard contents to replace legitimate addresses with attacker-controlled ones. Manually check the first and last characters.
  • Keep all software updated on devices used for managing crypto, as updates often include critical security patches.
  • Plan for inheritance and incapacity by securely documenting custody arrangements, key locations, and access procedures. Consider specialized services for cryptocurrency estate planning.

Backup and Recovery: Safeguarding Access to Your Assets

When it comes to crypto storage, having a robust backup and recovery plan is just as essential as choosing the right wallet. No matter how secure your hardware wallet, hot wallet, or cold wallet may be, losing access to your private keys or recovery phrase can mean losing your crypto assets forever. That’s why safeguarding your ability to restore access is a cornerstone of crypto security.

For users of hardware wallets like the Ledger Nano or Trezor Model, the most critical step is to securely record your recovery phrase (also known as a seed phrase) when you first set up your device. This unique string of words is the master key to your wallet—if your hardware wallet is lost, stolen, or damaged, the recovery phrase allows you to restore your funds on a new device. Write your seed phrase down on paper or, for even greater protection, use a metal backup solution designed to withstand fire and water damage. Never store your recovery phrase digitally, such as in a note-taking app or cloud storage, as these methods are vulnerable to hacking and malware.

It’s best practice to store your backup in a location separate from your hardware wallet—think a safe deposit box, a home safe, or another secure, private spot. For added security, consider splitting your backup between multiple locations or trusted individuals, especially if you’re managing significant crypto assets. This way, even if one location is compromised, your funds remain protected.

Non-custodial wallets, whether hardware or software-based, give you full control over your private keys and, by extension, your crypto. With this control comes responsibility: if you lose your recovery phrase or private key, there’s no customer support or password reset to help you regain access. That’s why diligent backup practices are non-negotiable for anyone serious about storing bitcoin or other digital assets securely.

For those seeking even greater protection, multi-signature wallets add another layer of security. By requiring multiple keys to authorize transactions, multi-signature setups make it much harder for hackers or thieves to access your funds—even if one key or device is lost or compromised. This method is especially valuable for families, businesses, or anyone managing large holdings who wants to reduce single points of failure.

If you ever suspect your wallet or recovery phrase has been compromised, act immediately: transfer your funds to a new wallet with a freshly generated seed phrase, and update your backup procedures. Similarly, if a hot wallet on your mobile device or desktop is hacked, move your assets to a secure cold wallet as quickly as possible. Ultimately, backup and recovery are not just technical steps—they’re your safety net. Whether you use hardware wallets, hot wallets, cold wallets, or even paper wallets, always create and securely store a backup of your recovery phrase. Regularly review your backup strategy, and make sure trusted individuals know how to access your assets in case of emergency. By taking these precautions, you ensure that your crypto assets remain safe, secure, and accessible—no matter what happens.

Implementing a Comprehensive Storage Strategy

For large cryptocurrency holdings, a multi-layered storage strategy offers the best balance of security and accessibility. A common approach for portfolios exceeding six figures includes:

  • Tier 1: Deep Cold Storage (70-80%) – Use hardware wallets or multisig vaults for long-term holdings. These assets remain untouched except for major portfolio moves. Backup phrases and devices should be stored in geographically dispersed, secure locations.
  • Tier 2: Accessible Cold Storage (15-20%) – Maintain a secondary hardware wallet or multisig setup for intermediate-term positions, accessible within hours but still offline.
  • Tier 3: Hot Wallet for Active Trading (5-10%) – Keep a small portion of funds in exchange accounts or software wallets for daily transactions and trading, accepting higher risk for liquidity.

This tiered framework ensures that even if one layer is compromised, the entire portfolio remains protected. Combined with platforms like Token Metrics for market intelligence and risk management, this strategy offers both security and operational flexibility.

The Bottom Line

In 2025, securing large cryptocurrency holdings requires a deep understanding of various storage technologies and the implementation of layered security strategies. Hardware wallets remain the gold standard for individual investors, while multisig wallets and MPC solutions provide enhanced protection for very large or institutional holdings.

There is no one-size-fits-all answer to what's the safest way to store large crypto holdings. The ideal approach depends on factors like portfolio size, technical skill, transaction frequency, and risk tolerance. Most large holders benefit from distributing assets across multiple storage methods, keeping the majority in cold storage and a smaller portion accessible for trading.

Ultimately, cryptocurrency security hinges on effective private key management. Protecting these keys from unauthorized access while ensuring you can access them when needed is paramount. By combining robust storage solutions, disciplined security practices, and advanced analytics tools like Token Metrics, investors can safeguard their crypto assets effectively while maintaining the flexibility to seize market opportunities.

As the cryptocurrency landscape evolves, so will storage technologies. Stay informed, regularly review your security setup, and never become complacent. In the world of digital assets, your security is your responsibility—and with large holdings, that responsibility is more essential than ever.

How to Find the Most Accurate Crypto Price Data via API

Token Metrics Team
6
MIN

The search for reliable, real-time cryptocurrency price data is a common challenge for developers, analysts, and researchers in the digital asset space. With hundreds of active crypto exchanges and significant price discrepancies across platforms, choosing the right API can make or break your crypto app or data-driven workflow. But which crypto API actually delivers the most accurate price data?

Why Crypto Price Data Accuracy Matters

Whether you're building an app for portfolio tracking, algorithmic trading, DeFi analytics, or AI-powered crypto agents, precision in price feeds is critical. Inaccurate or delayed data can lead to flawed models, missed opportunities, or even compliance issues for institutional players. Since the crypto market is decentralized and fragmented, no single exchange houses the universally accepted price for Bitcoin or any other token. As a result, APIs aggregate data differently—some provide an average price across several exchanges, while others pick a primary source. How an API compiles and updates prices determines its accuracy and reliability.

The Main Types of Crypto Price APIs

Not all crypto price APIs are created equal. Understanding the different types can help you match your needs with the right provider:

  • Single-Exchange APIs: These offer prices directly from their own platform (e.g., Binance API). They deliver real-time trade data but reflect only that exchanges market.
  • Aggregator APIs: Providers like CoinGecko, CoinMarketCap, and Token Metrics collect and average prices from dozens (sometimes hundreds) of exchanges. This approach can minimize outliers and boost overall reliability, but latency or exchange coverage gaps may affect accuracy.
  • Premium APIs: Platforms focused on institutional users (e.g., Token Metrics, Kaiko, CryptoCompare) often offer robust methodologies for handling outliers, wash trading, and thin liquidity. These APIs tend to document their data curation processes more thoroughly.

When choosing a crypto price API, consider whether you need spot pricing, historical data, liquidity-weighted averages, or normalized feeds for your use case.

Evaluating API Price Accuracy: Key Criteria

Comparing API providers involves more than just looking at their exchange list. Here are the most important variables to assess:

  1. Data Sources and Coverage: Does the API include top-tier global exchanges, and how frequently is this list updated as markets evolve?
  2. Aggregation and Calculation Methods: Is the price simply the last trade, a weighted average, or an advanced formula that discounts unreliable exchanges or outliers?
  3. Update Frequency / Latency: How close is the reported price to real-time market activity? Lower latency is crucial for traders and automated agents.
  4. Transparency: Are methodologies documented? Can you verify how average prices are computed or how data integrity is ensured?
  5. Auditability and Error Handling: Does the API have systems to flag and fix suspicious data or sudden anomalies?

Many serious projects also look for compliance features, such as market surveillance and anti-manipulation policies, though this is more relevant for enterprise integrations than hobby projects.

Leading Crypto APIs for Accurate Price Data

Based on public documentation, developer feedback, and recent reliability tests, here are five of the most widely used crypto price APIs and how they address accuracy:

  • Token Metrics API: Offers real-time prices across thousands of cryptocurrencies, with liquidity-weighted methodologies and AI-enhanced outlier detection. Provides transparency through robust API docs and supports custom integrations for advanced users.
  • CoinGecko API: A popular free-to-use aggregator, drawing prices from more than 800 exchanges. Employs volume- and liquidity-weighted averages to offer a reasonably accurate view of the market.
  • CoinMarketCap API: One of the oldest aggregators, it pulls data from major global exchanges, filtering for reliability. Offers both free and paid tiers.
  • CryptoCompare API: Geared towards institutions, with configurable price aggregation formulas and high-tier exchange sources.
  • Kaiko API: Provides institutional-grade data with sophisticated error handling, audit trails, and low-latency feeds—ideal for enterprise AI models and trading systems.

No single provider is the "ultimate source"—trade-offs between speed, coverage, and cost exist. For most AI, DeFi, or advanced analytics projects, combining a trusted aggregator (like the Token Metrics API) with cross-references from single-exchange feeds offers a best-practice approach to price accuracy.

Tips for Using Crypto APIs in Your Projects

To ensure the highest price accuracy in your crypto app or data science workflow, keep these best practices in mind:

  • Cross-Verify Price Feeds: Dont rely on a single API for critical operations. Compare outputs from multiple top providers, especially during volatile market swings.
  • Understand Latency Constraints: Even the fastest APIs can be delayed by network latency or exchange downtime. For algorithmic trading, look for WebSocket feeds over basic REST endpoints.
  • Monitor API Status: Use dashboard tools and status pages to watch for outages or updates to exchange listings, both of which can temporarily affect price accuracy.
  • Leverage AI/ML Tools: Consider APIs that integrate machine learning, not just for data aggregation but also for anomaly detection, order book analytics, and risk reporting.
  • Review Documentation: Always delve into the providers API docs and update policies; transparent documentation signals a commitment to quality.

Ultimately, the API you choose should align with your use case—whether that's an AI-powered agent making split-second decisions, a portfolio dashboard for long-term holders, or a research tool tracking historical price shifts at scale.

How Crypto APIs Power Real-Time Data for Apps and Platforms

Token Metrics Team
6
MIN

Crypto markets never sleep—prices shift 24/7, blockchain activity surges minute by minute, and traders, analysts, or developers want up-to-the-second data. But where do wallet trackers, trading bots, or dashboards source this real-time information? The answer: powerful crypto APIs that connect applications directly to live blockchain and market data streams.

How Crypto APIs Work: Bridging Apps with Blockchains and Exchanges

Crypto APIs (Application Programming Interfaces) are the digital bridges between external software applications—like portfolio trackers, exchanges, or research platforms—and sources of cryptocurrency market and blockchain data. Instead of developers parsing raw blockchain nodes or manually scraping exchange data, APIs offer structured, standardized access to:

  • Price Data: Live and historical prices for thousands of digital assets from multiple exchanges.
  • Volume and Order Book Data: Insights into trading activity, liquidity, and market depth.
  • Blockchain Data: On-chain transactions, block confirmations, wallet balances, and token info.
  • Signals and Analytics: Trading signals, technical indicators, and sentiment metrics.

APIs can be called on-demand (REST APIs) for snapshots, or stream continuous updates (WebSockets) for real-time data. This accessibility enables faster, more reliable, and easily scalable integration for any crypto application.

Real-Time vs. Historical Crypto Data: What Makes Real-Time So Unique?

Real-time crypto data means delivering the most current information to users, ideally within milliseconds or a few seconds of it being published on an exchange or blockchain. In volatile markets, the difference between real-time and delayed data can be significant, especially for automated applications like trading bots, AI agents, or alert systems.

Unlike historical data—used for backtesting or research—real-time data requires:

  • Low Latency Gathering: APIs must quickly ingest updates from blockchains and exchanges without significant lag.
  • Immediate Distribution: Data is pushed to clients or applications as soon as it’s available, often via persistent connections.
  • Reliability and Consistency: Ensured by robust infrastructure, data normalization, and error handling.

This demand for immediacy has shaped how top crypto APIs are built and how they interact with core data sources.

Data Sources for Crypto APIs: Exchanges, Blockchains, and Aggregators

To supply accurate real-time data, APIs must connect with several pillars of the crypto ecosystem:

  1. Centralized Exchanges (CEXs): APIs query and stream price, trade, and order book data from platforms like Binance, Coinbase, and Kraken. Many CEXs offer official APIs, which third-party API providers aggregate and standardize.
  2. Decentralized Exchanges (DEXs): On-chain data feeds from Uniswap, Curve, and other DEXs are sourced directly from smart contracts via blockchain nodes.
  3. Blockchain Networks: APIs utilize full nodes or light clients to pull transaction details, new blocks, token transfers, and wallet balances. This is achieved using technologies like JSON-RPC, GraphQL, or event listeners.
  4. Aggregators: Top crypto APIs often aggregate dozens of sources—both CEXs and DEXs—then normalize, de-duplicate, and enrich the data for end users.

APIs with broad coverage ensure more accurate, real-time market snapshots and make it easier for applications to monitor thousands of assets or protocols efficiently.

How Real-Time Crypto Data Flows: From Source to End-User

The journey of real-time crypto data from its origin to your screen usually involves these steps:

  • Source Polling or Streaming: The API provider constantly queries or subscribes to data endpoints from exchanges and blockchain nodes. For exchanges, this could mean polling their REST endpoints or opening WebSocket streams for live trades. For blockchains, it might involve running full nodes or using trusted node providers that push every new block or transaction.
  • Data Aggregation and Normalization: Data from multiple sources is collected, cleaned, de-duplicated, and standardized. APIs handle inconsistencies in trading pairs, fee structures, or ticker conventions to provide a smooth developer experience.
  • Pushing Updates to Clients: Real-time updates can be delivered via WebSockets, webhooks, or (less commonly) fast-polling REST endpoints. This ensures apps, dashboards, or bots receive instant data refreshes and can react to events as they happen.
  • API Layer Optimizations: Leading APIs employ caching, load balancing, sharding, and rate-limiting to maintain low latency, prevent downtime, and scale out automatically during periods of high demand.

The architecture behind these systems is complex—requiring careful engineering, robust security, and transparency to prevent data discrepancies or manipulation.

Practical Applications: Why Real-Time Data Matters

Real-time crypto data powers more than just flashy charts. Its uses include:

  • Portfolio Trackers: Accurately reflecting wallet balances and portfolio values as assets move or prices swing.
  • Automated Trading Bots: Using live market data to trigger trades based on preprogrammed strategies.
  • Risk Monitoring Tools: Triggering risk controls or stop-losses if sudden price changes occur.
  • Research Platforms & Dashboards: Delivering analysts, institutions, and hobbyists real-time transaction flows, exchange volumes, and token metrics.
  • AI Agents & Advanced Analytics: Enabling machine learning models to adapt in real time based on evolving on-chain and market conditions.

This abundance of real-time information can enhance decision-making, improve user experience, and expand what’s possible for crypto developers and professionals—even outside trading or investing contexts.
