NFTs, or non-fungible tokens, are gaining widespread popularity in the market for digital art and collectibles. In recent years, NFTs have become a cultural phenomenon, attracting the attention of crypto enthusiasts, digital art creators, and celebrities alike. As the Web 3.0 ecosystem continues to grow and adoption increases, many believe that NFTs will play a key role in the ownership of assets online.

So what are NFTs? Let's find out.

‍NFT Basics

NFTs, or non-fungible tokens, are a type of digital asset that represents ownership of something on the blockchain.

NFTs can be anything such as art, collectibles, music, profile pictures or PFP, DAO memberships, event tickets, gaming assets, virtual land, domain names, and so on. They can represent either completely digital assets or tokenized versions of assets that exist in the real world. Currently, there is a lot of excitement around using NFTs to sell virtual art.

Characteristics of NFTs

  • Ownership: NFT represents digital ownership of an item on a blockchain
  • Permanent: NFTs have data permanently stored within the token. This information includes images, messages, signatures, or any other data
  • Programmable: An NFT can be programmed to do anything. For example, an NFT artwork might be programmed to pay the artist royalties on every secondary sale of that artwork
  • Unique: NFTs are unique, and that uniqueness can be confirmed on a blockchain

How to Make an NFT

To create an NFT, or non-fungible token, you will need to first prepare your media file. NFTs can support a wide range of file types, including audio, images, and even 3D files. Some popular file types that are supported by NFTs include MP3, JPG, PNG, and GIF. You can also use 3D file formats like GLB to create NFTs that represent unique, digital objects.

Once your media is ready, you will need to set up a non-custodial wallet to securely store the cryptocurrency that you will use to buy, sell, and create NFTs. Non-custodial wallets are important because they allow you to retain control of your private keys, which are needed to access your cryptocurrency and make transactions. There are many different wallet options available, so it is important to do your research and choose one that is secure and user-friendly.

Once you have set up your wallet, you will need to buy Ethereum, or other fungible tokens depending on the blockchain being used, to cover the cost of minting your NFT. Ethereum is the most commonly used blockchain for NFTs, and it is typically the easiest to get started with. You can buy Ethereum using a variety of methods, including through a cryptocurrency exchange or from other individuals who are willing to sell.

Once you have your Ethereum, you will need to connect your wallet to an NFT marketplace like Rarible or OpenSea. These platforms allow you to easily create and mint your NFT, as well as trade and purchase NFTs created by others. To connect your wallet, simply tap the "Connect" button in the top right corner of the marketplace's website. This will create an account for you on the platform and allow you to begin creating your NFT.

To create your NFT, upload your media file to the platform and provide a description of your asset. You can choose to create a standalone piece, or create multiple NFTs of the same piece, each with its own unique characteristics. You can also set rules around royalties and other aspects of your NFT to ensure that you are fairly compensated for your work.

Once you are ready to mint your NFT, the process will require you to pay a small amount of ETH for transaction fees. This is necessary to get your NFT added to the blockchain and verified as unique. Once your NFT is minted, it will be available for trade and purchase on the marketplace. You can monitor the progress of your NFT and track its sales through your wallet or the marketplace's website.

NFT Secondary Markets

Creators make NFTs using blockchain-based minting platforms to retain more control over their creative output. Once NFTs are minted on a non-custodial wallet-compatible website, collectors and traders can sell these assets on the secondary market.

Here is a list of the most used NFT marketplaces:

  • OpenSea: OpenSea is the first and largest marketplace for NFTs. OpenSea is building tools that allow consumers to trade their items, creators to launch new digital works, and developers to build rich, integrated marketplaces for their digital items. It recently announced the support for Solana-based NFTs.
  • Coinbase NFT: Coinbase, a cryptocurrency exchange, recently launched its NFT marketplace in beta version to the public. This marketplace acts as a social media platform in which users can not only buy and sell NFTs but also interact with and showcase their collections using user profiles, likes, and comments.
  • Solanart: Solanart is the first and largest fully-fledged NFT marketplace on Solana. Users can get quick and easy access to digital collectibles, and explore, buy, and sell NFTs that run on the Solana blockchain.
  • Rarible: Rarible is a do-it-yourself NFT marketplace where you can mint NFTs when and how you please. Creators are highly favorable towards Rarible, as the minting process is free, easy, and unrestricted. Rarible’s native governance token “RARI” is used to incentivize platform users and give the community members a voice.
  • Nifty Gateway: Nifty Gateway is owned by the Gemini crypto exchange and has become one of the most known NFT marketplaces lately. They focus on viral drops from artists like Beeple, Trevor Jones, Pak, and more.
  • SuperRare: SuperRare (SR) is one of Ethereum’s debut crypto-art NFT marketplaces. Artists must be accepted to the platform before they can list their assets.

Notable NFT Projects

NFT-based companies have seen significant growth in recent years. Some notable examples include:

  • Yuga Labs: a blockchain technology company that creates Ethereum-based NFTs and digital collectibles. Yuga's most valuable NFT collection is Bored Ape Yacht Club, which has seen a floor price of over 150 ETH at its all-time high. In addition to apes, Yuga has also created dog NFTs, mutant apes, and deeds for its Metaverse. The company recently acquired Larva Labs, bringing high-value projects like Cryptopunks and Meebits under the Yuga brand. Yuga is backed by investors like Coinbase, Samsung, and Mark Cuban.
  • Doodles: a collection of 10,000 Ethereum-based NFTs created by artist BurntToast. The Doodles collection includes a wide range of visual traits, heads, costumes, and colorways. Owners of Doodles NFTs have exclusive access to new experiences like Space Doodles and Dooplicator.
  • Okay Bears: a collection of 10,000 Solana-based NFTs. Ownership of an Okay Bear grants access to a community of collectors and exclusive products, merchandise, and events.

Investing in NFTs

NFTs, or non-fungible tokens, provide many benefits as an investment vehicle.

One of the main advantages of NFTs is that they allow physical objects, such as artwork, to be tokenized.

Additionally, NFTs offer greater liquidity for investors, making it easier to trade and sell their assets.

The Future of NFTs

NFTs offer a new way to represent and prove ownership of assets on the blockchain.

This technology has already been used for digital art, collectibles, and in-game assets, but it has the potential to be applied to a wide range of other industries as well. For example, tokenized real estate could provide a way for people to invest in property without the barriers to entry that currently exist.

High-end fashion brands like Louis Vuitton have also expressed interest in using NFTs to track the ownership of luxury items.

Additionally, NFTs can be used to tokenize certifications, degrees, and licenses, providing a way to securely track and maintain this sensitive data on the blockchain.

Overall, the potential applications for NFTs are nearly limitless.

What Is ETF Trading? A Beginner’s Guide to Exchange-Traded Funds in 2025

Token Metrics Team
8 min
MIN

In today’s fast-paced financial markets, ETF trading has become one of the most popular and accessible investment strategies. Whether you're a traditional investor or a crypto enthusiast, understanding how ETF trading works can help you make smarter, more diversified investment decisions.

📈 What Is an ETF?

An ETF (Exchange-Traded Fund) is an investment fund that trades on stock exchanges, similar to individual stocks. Each ETF holds a collection of assets, such as:

  • Stocks (like the S&P 500)
  • Bonds
  • Commodities (like gold or oil)
  • Currencies
  • Cryptocurrencies (Bitcoin, Ethereum, etc.)

When you buy a share of an ETF, you're buying a fractional interest in the entire basket of assets. This makes ETFs a powerful tool for diversification, even for beginners.

đŸ’č What Is ETF Trading?

ETF trading refers to the buying and selling of ETF shares on an exchange—just like you would with Apple or Tesla stock. The value of an ETF changes throughout the trading day, based on the underlying value of its assets.

ETF trading is commonly used for:

  • Portfolio diversification
  • Hedging strategies
  • Thematic investing (e.g., AI, clean energy, DeFi)
  • Speculating on short-term price movements

You can trade ETFs via your online brokerage, investment app, or even through certain retirement accounts (like IRAs).

🔄 How Does ETF Trading Work?

Here’s a simplified version of how ETF trading works:

  1. ETF Provider Creates the Fund
    A company like BlackRock or Fidelity creates an ETF that holds a specific basket of assets.

  2. ETF Listed on an Exchange
    The ETF is listed on public stock exchanges such as the NYSE or Nasdaq.

  3. Investors Buy and Sell Shares
    Investors trade ETF shares just like stocks—prices fluctuate throughout the day.

  4. Market Makers Maintain Liquidity
    Authorized participants ensure ETF prices closely match the value of the underlying assets (called the Net Asset Value or NAV).

đŸȘ™ What About Crypto ETFs?

In 2025, crypto ETFs have emerged as one of the fastest-growing segments of the ETF market.

Crypto ETFs allow investors to gain exposure to cryptocurrencies without owning the actual coins. These ETFs are regulated, secure, and accessible through traditional finance platforms.

There are two types:

  • Spot Crypto ETFs (hold actual crypto assets like Bitcoin or Ethereum)
  • Futures Crypto ETFs (track the price of crypto futures contracts)

Example: BlackRock’s iShares Bitcoin Trust (IBIT) is a spot Bitcoin ETF with billions in assets under management (AUM) in 2025.

✅ Benefits of ETF Trading

ETF trading offers unique advantages for both retail and institutional investors:

1. Diversification

Instead of buying dozens of individual stocks, ETFs offer broad exposure to sectors, themes, or markets in a single trade.

2. Liquidity

ETFs trade like stocks—buy or sell at any time during market hours. This makes them more flexible than traditional mutual funds.

3. Cost Efficiency

Many ETFs have low expense ratios, often under 0.25%. You avoid the high fees associated with actively managed funds.

4. Accessibility

Trade ETFs using any brokerage account. You don’t need to be an accredited investor or a crypto expert.

5. Tax Advantages

ETFs are generally more tax-efficient than mutual funds due to the in-kind creation/redemption process.

⚠ Risks of ETF Trading

ETF trading, like all investing, carries risks:

1. Market Risk

ETF prices can go up or down depending on market conditions.

2. Liquidity Risk

Not all ETFs are highly traded. Low volume can lead to wide bid/ask spreads and slippage.

3. Tracking Error

Some ETFs fail to perfectly mirror their benchmark, especially futures-based crypto ETFs.

4. Sector Risk

Thematic ETFs (e.g., blockchain, AI) can be highly concentrated and volatile.

What Is a Bitcoin ETF? A Beginner’s Guide to Understanding Bitcoin Exchange-Traded Funds in 2025

Token Metrics Team
8 min

The cryptocurrency world continues to evolve rapidly, and one of the most significant milestones in recent years has been the approval and rise of Bitcoin ETFs. If you’ve ever wondered, “What is a Bitcoin ETF and why is it important?” — this guide breaks it down in simple terms.

In this highly informative blog, we’ll explore:

  • What a Bitcoin ETF is
  • Types of Bitcoin ETFs
  • Benefits and risks
  • Why Bitcoin ETFs matter for crypto adoption
  • How to analyze Bitcoin ETFs using Token Metrics tools

📈 What Is a Bitcoin ETF?

A Bitcoin ETF (Exchange-Traded Fund) is a financial product that allows investors to gain exposure to the price movements of Bitcoin without having to own or manage actual Bitcoin.

Just like buying a stock, investors can purchase shares of a Bitcoin ETF through traditional brokerage accounts. These shares represent ownership in a fund that tracks the price of Bitcoin.

In essence, a Bitcoin ETF bridges the gap between traditional finance and crypto investing.

🔄 How Does a Bitcoin ETF Work?

Bitcoin ETFs are created and managed by large financial institutions or asset managers. These funds:

  1. Buy Bitcoin directly (in spot ETFs), or
  2. Invest in Bitcoin futures contracts (in futures ETFs)
  3. Issue ETF shares that track the price performance of Bitcoin

These shares are then listed on stock exchanges like the NYSE, Nasdaq, or CBOE, where they can be bought or sold just like regular stocks.

🔍 Types of Bitcoin ETFs

There are two main types of Bitcoin ETFs:

1. Spot Bitcoin ETFs

  • Hold actual Bitcoin in custody
  • Track the real-time market price of Bitcoin
  • Provide direct exposure to Bitcoin’s price
  • Approved in the U.S. starting in early 2024 (e.g., BlackRock’s iShares Bitcoin Trust)

2. Futures-Based Bitcoin ETFs

  • Track Bitcoin futures contracts (derivatives)
  • Do not hold actual Bitcoin
  • Subject to contango and tracking errors
  • Were the first type approved (e.g., ProShares BITO)

In 2025, spot ETFs are considered superior due to their more accurate and direct exposure.

✅ Benefits of Bitcoin ETFs

Bitcoin ETFs offer several key advantages:

1. Accessibility

Investors can buy Bitcoin exposure through traditional brokerage platforms like Fidelity, Schwab, or Robinhood—no need for crypto wallets or private keys.

2. Regulation and Security

ETFs are regulated by institutions like the SEC and are managed by trusted financial firms, offering greater transparency and investor protection.

3. Tax Efficiency

Buying and selling ETFs may provide more favorable tax treatment compared to transacting in physical Bitcoin directly.

4. Institutional Adoption

Bitcoin ETFs enable pension funds, hedge funds, and banks to legally and easily gain exposure to BTC. Inflows from these entities have driven billions into Bitcoin in 2024 and 2025.

⚠ Risks of Bitcoin ETFs

Despite their benefits, Bitcoin ETFs come with a few risks:

1. Price Tracking Errors

Futures ETFs may deviate from Bitcoin’s spot price due to volatility and contract rollover costs.

2. Management Fees

ETF providers charge an annual fee (0.20%–1.00%), which can reduce long-term returns.

3. Lack of Custody Control

You don’t actually own Bitcoin when you hold an ETF—so you can’t transfer it or use it for DeFi or crypto payments.

4. Market Volatility

Bitcoin remains a highly volatile asset. ETF shares may still experience massive price swings.

đŸ›ïž Why Bitcoin ETFs Matter in 2025

The approval and adoption of Bitcoin ETFs mark a turning point in mainstream crypto acceptance. Here’s why:

  • Over $60 billion has flowed into U.S.-listed Bitcoin ETFs since January 2024
  • Institutions like BlackRock, Fidelity, and ARK Invest now actively manage Bitcoin exposure
  • Bitcoin ETF holdings reduce circulating supply, contributing to BTC’s price surge past $118,000 in mid-2025
  • Countries outside the U.S., including Canada and Hong Kong, are expanding their Bitcoin ETF offerings

đŸ€– How Token Metrics Helps You Analyze Bitcoin ETFs

While traditional investors focus on ETF tickers, smart crypto investors turn to platforms like Token Metrics to get deeper insights.

đŸ”č AI-Powered Bitcoin Forecasts

Token Metrics uses machine learning to predict short- and long-term Bitcoin price trends. As of June 28, the AI turned bullish, signaling BTC's breakout past $110,000.

đŸ”č Exchange Reserve Monitoring

The platform tracks Bitcoin’s exchange reserves, showing a drop from 3.25M to 2.55M BTC—a bullish signal due to reduced sell-side pressure.

đŸ”č ETF Flow Analysis

Token Metrics integrates on-chain data and fund inflows to measure:

  • How much BTC ETFs are buying
  • Impact on liquidity and price
  • Sentiment shifts among institutional investors

đŸ”č Alerts and Grades

You can set up custom price alerts for Bitcoin and receive Trader and Investor Grades based on 80+ real-time metrics.

These tools allow you to react faster than ETF investors relying on traditional media or quarterly reports.

📈 Bitcoin ETF Performance So Far

As of July 2025:

  • BlackRock’s iShares Bitcoin Trust (IBIT) holds over $18B in BTC
  • Fidelity’s ETF surpassed $12B in AUM
  • ETF buying pressure is one of the main drivers behind Bitcoin’s 2025 bull run

💡 Pro Tips Before Investing in a Bitcoin ETF

  1. Compare fees across ETFs (lower = better for long-term holdings)
  2. Choose spot ETFs over futures ETFs for more accurate performance
  3. Use Token Metrics to track BTC signals and time your entry
  4. Understand your goals—ETFs are great for passive exposure but not for on-chain crypto utility

🧠 Final Thoughts

A Bitcoin ETF is one of the easiest ways to gain exposure to Bitcoin in 2025. Whether you’re a traditional investor looking to diversify or a crypto-native looking for a regulated option, ETFs offer accessibility, safety, and legitimacy.

But don’t stop at just buying shares—pair your ETF exposure with real-time intelligence from Token Metrics.

With institutional momentum accelerating, regulatory clarity improving, and AI tools like Token Metrics giving you an edge, there’s never been a better time to understand and invest in Bitcoin ETFs.

Hot Wallets vs. Cold Wallets: What’s the Difference and Which Crypto Wallet To Use in 2025?

Token Metrics Team

MIN

As cryptocurrency adoption accelerates globally in 2025, one critical question for both beginners and experienced investors is: Where should you store your crypto assets safely?

The answer lies in understanding the difference between hot wallets and cold wallets — the two main categories of cryptocurrency storage. This highly informative and SEO-optimized blog will help you understand:

  • What hot and cold wallets are
  • Key differences between them
  • Pros and cons of each
  • Which one is right for you
  • How platforms like Token Metrics help you choose and manage your wallet securely

🔐 What Is a Cryptocurrency Wallet?

A crypto wallet stores your private and public keys, enabling you to send, receive, and manage digital assets like Bitcoin, Ethereum, or altcoins. Unlike traditional bank accounts, crypto wallets give you full control over your funds — but with that control comes the responsibility of securing them.

Wallets are typically categorized as:

  • Hot Wallets – connected to the internet
  • Cold Wallets – offline storage solutions

⚡ What Is a Hot Wallet?

A hot wallet is a crypto wallet that is connected to the internet. It’s designed for easy access and quick transactions, making it ideal for active traders and everyday use.

đŸ”č Examples of Hot Wallets:

  • Web wallets: MetaMask, Trust Wallet, Phantom, Rainbow
  • Desktop wallets: Exodus, Electrum
  • Mobile wallets: Coinbase Wallet, Atomic Wallet
  • Exchange wallets: Binance, Coinbase (custodial)

✅ Pros of Hot Wallets:

  • Instant access to crypto
  • User-friendly interfaces
  • Ideal for frequent trading or DeFi
  • Compatible with most crypto platforms

❌ Cons of Hot Wallets:

  • Vulnerable to hacks and phishing
  • Depends on internet connection
  • Risk of malware or keylogging
  • Not ideal for large holdings

Hot wallets are often recommended for storing smaller amounts of crypto for daily use.

🧊 What Is a Cold Wallet?

A cold wallet refers to any crypto wallet that is not connected to the internet. It’s a form of offline storage designed for maximum security.

đŸ”č Examples of Cold Wallets:

  • Hardware wallets: Ledger Nano X, Trezor Model T
  • Paper wallets: Printed QR codes with private keys
  • Air-gapped computers: Devices permanently offline

✅ Pros of Cold Wallets:

  • Immune to online attacks
  • Long-term storage for HODLing
  • Control over private keys
  • Ideal for institutional and high-net-worth users

❌ Cons of Cold Wallets:

  • Less convenient for quick access
  • Physical loss or damage is a risk
  • Requires technical knowledge
  • More expensive (hardware wallets can cost $50–$200)

Cold wallets are ideal for long-term investors storing large amounts of crypto.

🔄 Hot Wallet vs. Cold Wallet: Key Differences

🔧 How to Use Hot and Cold Wallets Together (Hybrid Strategy)

Many crypto investors in 2025 use a dual-wallet strategy:

  • Hot wallet for trading, staking, and DeFi
  • Cold wallet for long-term storage and high-value assets

This balances convenience and security while minimizing exposure to threats.

For example:

  • Use a hot wallet like MetaMask to access the Token Metrics Moonshots tab and buy trending altcoins.
  • Transfer profits to your cold wallet (e.g., Ledger) for safekeeping.

🧠 How Token Metrics Helps You Manage Wallet Security

đŸ”č Wallet Integrations

Token Metrics supports:

  • MetaMask, WalletConnect, and other hot wallets
  • Portfolio tracking synced with your wallet
  • Real-time alerts when assets in your wallet are surging or at risk

Token Metrics helps reduce the need to frequently move funds by:

  • Identifying only high-quality tokens using AI Trader and Investor Grades
  • Sending price alerts, so you know when to buy/sell
  • Providing in-platform swap tools for direct trades from your hot wallet

đŸ”č Moonshot Monitoring

For early-stage altcoins, timing is everything. Token Metrics lets you:

  • Monitor your Moonshot investments
  • Get notified when to take profits or exit
  • Transfer to cold storage with a single click

🔒 Hot Wallet Security Tips (2025 Edition)

If you’re using a hot wallet:

  • Enable 2FA (Two-Factor Authentication)
  • Use a hardware wallet to sign large transactions
  • Avoid clicking suspicious links or connecting to unknown dApps
  • Disconnect wallets after use

Always back up your seed phrase and store it securely offline.

💬 Which Wallet Should You Use?

‍

đŸ§© Final Thoughts

Whether you’re storing $100 or $100,000 in cryptocurrency, your wallet choice directly impacts your security, accessibility, and peace of mind.

  • Hot wallets offer convenience, but must be used with caution
  • Cold wallets offer security, but come with trade-offs in usability
  • Platforms like Token Metrics bridge the gap by offering real-time insights, wallet integrations, and AI-driven trading tools

In 2025, don’t just store your crypto—store it wisely. Combine hot and cold wallet strategies and leverage tools like Token Metrics to build a secure, intelligent crypto portfolio.
