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.

Introduction: Why Risk Management Matters More Than Ever

Cryptocurrency has always been volatile, but in 2025, the stakes are even higher. With billions flowing into AI‑driven tokens, real‑world asset (RWA) projects, DeFi protocols, and meme coins, the crypto market is more complex than ever.

While the potential for profits is enormous, so are the risks. Poor risk management can quickly turn promising portfolios into catastrophic losses. To succeed, you need structured strategies and AI‑powered insights from platforms like Token Metrics to help you make smarter, data‑driven decisions.

This guide explores the top strategies for managing crypto risk in 2025 — helping you stay profitable even in turbulent markets.

1. Diversify Across Assets and Narratives

Don’t put all your crypto in one basket.

Diversification reduces your exposure to individual asset failures. In 2025, this means spreading across:

  • Large‑Caps (e.g., BTC, ETH): Lower risk and strong liquidity.
  • Mid‑Caps (e.g., Polygon, Arbitrum): Balanced growth potential.
  • Small‑Caps (e.g., Token Metrics AI (TMAI)): High‑risk, high‑reward narrative plays.
  • Stablecoins (e.g., USDC): For liquidity and hedging against market crashes.

Pro Tip: Use Token Metrics’ portfolio optimization tool to create a diversified, AI‑recommended allocation aligned with your risk tolerance.

2. Set Clear Position Sizes

Position sizing determines how much of your portfolio is allocated to a single asset.

Key Rule: Never risk more than you’re willing to lose.

  • Allocate smaller percentages to volatile small‑caps and larger percentages to proven, stable coins.
  • Adjust sizing based on AI‑driven asset ratings from Token Metrics, which score coins by fundamentals and risk factors.

3. Use Stop‑Loss and Take‑Profit Orders

Crypto markets move fast — sometimes too fast for manual reactions.

Stop‑Loss Orders:

  • Automatically sell assets when they drop to a pre‑set level, limiting downside losses.

Take‑Profit Orders:

  • Lock in gains when a token hits your target price, avoiding the “ride it back down” mistake.

Why It Works: These orders enforce discipline, removing emotional decision‑making from the equation.

4. Hedge with Stablecoins

Stablecoins like USDC and USDT are essential for risk management.

  • Protect against sudden market drops by keeping 5–15% of your portfolio in stablecoins.
  • Use stablecoins for buying dips without needing to sell other holdings at a loss.

Platforms like Token Metrics help track the optimal balance between stablecoins and risk assets for your portfolio.

5. Manage Leverage Carefully

Leverage amplifies both gains and losses.

  • Avoid over‑leveraging in a volatile market.
  • If using leverage, keep it low (1–3x) and apply strict stop‑loss rules.

AI‑powered insights from Token Metrics can help you assess volatility before taking leveraged positions.

6. Use Dollar‑Cost Averaging (DCA)

DCA means investing a fixed amount regularly, regardless of price.

  • Helps smooth out volatility by buying over time.
  • Reduces emotional trading decisions.

Pairing DCA with Token Metrics’ trend analysis ensures you’re accumulating assets with strong AI‑verified fundamentals.

7. Actively Rebalance Your Portfolio

Markets shift quickly. Rebalancing keeps your portfolio aligned with your goals.

Rebalance when:

  • An asset grows disproportionately large.
  • AI‑driven insights suggest a narrative is weakening.

Token Metrics’ portfolio tracker helps monitor your allocations and signals when adjustments are needed.

8. Stay Ahead of Market Narratives

Narratives drive capital flows in crypto — AI tokens, DeFi 2.0, RWAs, and more are shaping 2025.

Why It Matters:

  • Early identification of narratives allows you to capitalize on growth sectors.
  • Exiting fading narratives reduces losses from declining trends.

Token Metrics’ narrative detection tools help you spot these shifts early.

9. Secure Your Assets

Even the best portfolio is useless if it’s hacked.

  • Use hardware wallets (e.g., Ledger, Trezor) for long‑term storage.
  • Enable two‑factor authentication (2FA) on all exchange accounts.
  • Avoid storing large sums on centralized exchanges.

10. Stay Informed

Crypto moves at lightning speed. Staying informed reduces surprises:

  • Follow regulatory updates: Rules are evolving globally in 2025.
  • Track on‑chain data: Use Token Metrics to monitor wallet activity, token burns, and developer engagement.
  • Join crypto communities: Gain insights from experienced traders and analysts.

Practical Example: A Risk‑Managed Portfolio for 2025

  • 40% Bitcoin & Ethereum: Stability and staking income.
  • 30% Narrative‑Driven Assets: AI tokens like TMAI, Layer 2 solutions, and DeFi protocols.
  • 15% Stablecoins: Hedge against volatility and provide liquidity.
  • 10% Yield‑Generating Assets: Staking and liquidity pools.
  • 5% High‑Risk Plays: Speculative small‑caps or meme tokens.

‍

This portfolio balances security, growth, and liquidity.

Common Risk Management Mistakes

  • Overexposure to hype tokens: Avoid allocating heavily to meme coins.
  • Ignoring exit strategies: Always have profit targets.
  • Emotional trading: Stick to AI‑guided data, not fear or FOMO.

Conclusion

Managing risk in crypto isn’t about avoiding volatility — it’s about embracing it intelligently.

Introduction

Zero Knowledge Proofs (ZKPs) represent a groundbreaking cryptographic concept that enables one party to prove knowledge of specific information to another party without revealing the information itself. This technology is rapidly gaining traction within blockchain ecosystems and privacy-focused applications, offering novel approaches to verification and security without compromising sensitive data.

Basics of Zero Knowledge Proofs

At its core, a Zero Knowledge Proof is a method by which a prover demonstrates to a verifier that a given statement is true, without revealing any additional information beyond the validity of the statement. Introduced in the 1980s, ZKPs rely on complex mathematical algorithms to ensure that knowledge can be proven without disclosure, preserving confidentiality.

The three essential properties that characterize zero knowledge proofs are:

  • Completeness: If the statement is true, an honest verifier will be convinced by an honest prover.
  • Soundness: If the statement is false, no dishonest prover can convince the honest verifier otherwise.
  • Zero-Knowledge: The verifier learns nothing other than the fact the statement is true, gaining no additional knowledge about the actual information.

Types of Zero Knowledge Proofs

There are several approaches to implementing ZKPs, each with its trade-offs and applications. Two of the most significant forms include zk-SNARKs and zk-STARKs.

  • zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge): These are compact proofs that require minimal data for verification and do not require back-and-forth interaction between prover and verifier after setup. zk-SNARKs are widely used in privacy-oriented blockchains such as Zcash.
  • zk-STARKs (Zero-Knowledge Scalable Transparent Arguments of Knowledge): An evolution of zk-SNARKs, zk-STARKs remove the need for a trusted setup and improve scalability and transparency, although generating proofs may be more computationally intensive.

Applications in Blockchain and Cryptography

Zero Knowledge Proofs have considerable implications for enhancing privacy and scalability in decentralized systems. Key applications include:

  • Privacy Encryption: ZKPs enable private transactions by allowing users to confirm transaction validity without revealing participant identities or transaction details.
  • Identity Verification: Users can prove attributes such as age or citizenship without disclosing personal data, reducing risks associated with data leaks and identity theft.
  • Secure Voting Systems: Ensuring the legitimacy of votes while keeping individual votes confidential.
  • Scalability Solutions: By verifying computations off-chain with ZKPs, blockchain networks can reduce on-chain data processing, improving throughput and efficiency.

Challenges and Limitations

Despite their potential, Zero Knowledge Proofs face notable challenges that require careful consideration in practical deployment:

  • Computational Overhead: Generating zero knowledge proofs can be resource-intensive, particularly for complicated statements or large data sets.
  • Trusted Setup Concerns: Some ZKP systems, such as zk-SNARKs, require an initial trusted setup, which poses risks if compromised.
  • Implementation Complexity: Developing robust zero knowledge protocols demands advanced cryptographic expertise and rigorous security auditing.

Role of AI in Zero Knowledge Proof Analysis

Advancements in Artificial Intelligence (AI) have begun to complement cryptographic research, including the exploration and utilization of Zero Knowledge Proofs. AI-driven analytical tools can assist researchers and developers by:

  • Optimizing cryptographic algorithms for efficient proof generation.
  • Performing advanced pattern recognition on blockchain data enhanced by ZKPs to uncover usage trends without compromising privacy.
  • Supporting risk management frameworks by assessing protocol security based on integrated cryptographic parameters.

Platforms such as Token Metrics leverage AI-driven research to analyze emerging cryptographic technologies, including zero knowledge protocols, offering quantitative insights into technological developments and ecosystem dynamics.
