What Is an NFT? Complete Guide to Non-Fungible Tokens (2025)

Token Metrics Team
6 min
MIN

Over the past few years, NFTs (Non-Fungible Tokens) have exploded in popularity—revolutionizing the way we think about digital ownership, art, gaming, collectibles, and more. In 2025, NFTs continue to shape the future of the internet, transforming everything from music rights to virtual real estate.

If you're wondering “What is an NFT?” or how they actually work, this guide breaks it down for you. We’ll also explore how AI-powered tools like Token Metrics can help you identify high-value NFT-related tokens and investment opportunities.

🔍 What Does NFT Stand For?

NFT stands for Non-Fungible Token. Let’s break that down:

  • Token: A digital asset that exists on a blockchain.
  • Non-Fungible: It’s unique and cannot be replaced with something else of equal value. (Unlike cryptocurrencies like Bitcoin, where each BTC is the same.)

So, an NFT is a unique digital asset stored on a blockchain, representing ownership of a specific item—like artwork, music, a tweet, a game character, or a piece of virtual land.

🎹 What Can Be an NFT?

NFTs aren’t just limited to pixelated apes or JPEGs. In 2025, NFTs power a broad range of digital assets:

  • Digital Art: Artworks, animations, and generative art
  • Collectibles: Rare items like trading cards or profile picture (PFP) projects
  • Gaming Assets: In-game skins, weapons, characters, and land (e.g., in The Sandbox or Decentraland)
  • Music and Media: Songs, albums, and exclusive content drops
  • Virtual Real Estate: Land parcels in the metaverse
  • Domain Names: Blockchain-based domain ownership
  • Identity & Access: Membership passes, event tickets, or certification credentials

Each NFT has a unique identifier and metadata that distinguish it from any other asset.

đŸ› ïž How Do NFTs Work?

NFTs are built and recorded on blockchains, most commonly on Ethereum using ERC-721 or ERC-1155 standards. Here’s how they work:

  1. Minting: Turning a digital file into a token on the blockchain
  2. Metadata: Storing details like title, creator, image URL, and traits
  3. Ownership: A smart contract verifies the wallet that owns the NFT
  4. Transferability: NFTs can be sold, traded, or gifted using marketplaces

Because of blockchain immutability, ownership is transparent, verifiable, and permanent.

📈 Why Are NFTs Valuable?

Several reasons explain the rising value and popularity of NFTs:

  • Digital Ownership: You own the asset—not a platform
  • Proven Scarcity: Many NFTs are limited in supply
  • Creator Royalties: Artists earn fees on secondary sales
  • Utility & Access: Some NFTs unlock real-world benefits, games, or private groups
  • Social Status: PFPs like CryptoPunks or Bored Ape Yacht Club are digital status symbols
  • Speculation: Many treat NFTs as investments, betting on future appreciation

In 2025, NFTs have gone beyond hype to form the foundation of Web3 identity and ownership.

💰 How to Buy an NFT

To buy an NFT, you’ll need:

  1. A crypto wallet (like MetaMask)
  2. Some ETH or other supported crypto for payment and gas fees
  3. An NFT marketplace like OpenSea, Blur, Magic Eden, or Rarible

Steps to Buy:

  • Fund your wallet
  • Connect to a marketplace
  • Browse collections
  • Click “Buy Now” or place a bid
  • Approve the transaction

Once purchased, the NFT is transferred to your wallet and viewable on your profile.

⚠ Are NFTs Safe?

NFTs are secure if you follow best practices. However, scams and phishing attacks are common.

Security Tips:

  • Never share your seed phrase
  • Verify contract addresses before minting
  • Don’t connect your wallet to unknown sites
  • Use hardware wallets for high-value NFTs
  • Bookmark official sites

🧠 How Token Metrics Helps You Identify NFT-Related Investments

NFTs are not just collectibles—they’re tied to blockchain ecosystems and tokens. Platforms like Token Metrics help you identify high-potential NFT projects, gaming ecosystems, and utility tokens powering the space.

đŸ§© Popular NFT Blockchains in 2025

NFTs are no longer limited to Ethereum. In 2025, several chains offer faster, cheaper minting and trading:

Token Metrics tracks all these chains, offering a cross-chain perspective for NFT investing.

đŸȘ™ What Are NFT Tokens?

Many NFT ecosystems have their own fungible tokens used for governance, staking, or ecosystem rewards. Examples include:

  • $APE (Bored Ape Yacht Club)
  • $MAGIC (TreasureDAO)
  • $IMX (Immutable X)
  • $LOOKS (LooksRare)
  • $BLUR (Blur marketplace)

These tokens can rise in value based on NFT trading volume, user adoption, and staking incentives. Token Metrics’ analytics help traders spot breakout opportunities early.

🚀 Future of NFTs in 2025 and Beyond

NFTs are evolving fast. In 2025, they’re used for more than art and gaming:

  • NFTs as IDs: Used for logging into apps and verifying reputation
  • Real-world assets: Tokenizing real estate, music royalties, and legal contracts
  • DeFi integrations: NFTs used as collateral in lending protocols
  • Event access: NFTs as tickets for IRL and virtual experiences
  • AI x NFTs: Generative AI tools minting and managing NFT metadata autonomously

Expect continued innovation, and stay ahead using tools like Token Metrics.

🧠 Final Thoughts: Are NFTs Worth It?

NFTs are more than a trend — they represent the digitization of ownership in the Web3 era. From art and identity to games and finance, NFTs unlock new possibilities for creators and collectors alike.

If you're looking to explore NFT opportunities beyond collectibles—Token Metrics gives you the data, AI tools, and insights you need to invest intelligently.

As the popularity of cryptocurrencies continues to grow in 2025, more people are seeking safe and secure ways to manage their digital assets. The first step in your crypto journey? Creating a crypto wallet.

In this guide, we’ll explain:

  • What a crypto wallet is
  • Different types of wallets
  • How to create one (step-by-step)
  • Tips for securing your wallet
  • How Token Metrics can help you trade smarter after setup

đŸȘ™ What Is a Crypto Wallet?

A crypto wallet is a digital tool that allows you to store, receive, and send cryptocurrencies like Bitcoin, Ethereum, and thousands of altcoins. Instead of holding physical money, it stores your private and public keys, giving you access to your blockchain assets.

Two Major Types:

  1. Hot Wallets – connected to the internet (ideal for active users)
  2. Cold Wallets – offline and more secure (ideal for long-term storage)

Whether you're buying Bitcoin for the first time or diving into DeFi tokens, you'll need a crypto wallet to safely store and manage your coins.

đŸ”„ Hot Wallets vs. 🧊 Cold Wallets

‍

‍

Hot wallets are easier to set up and use, while cold wallets offer greater protection against hacks and malware.

đŸ› ïž How to Create a Crypto Wallet (Step-by-Step)

Option 1: Creating a Hot Wallet (e.g., MetaMask or Trust Wallet)

Step 1: Download the App or Browser Extension

Step 2: Create a New Wallet

  • Click “Create a Wallet”
  • Set a strong password

Step 3: Backup Your Recovery Phrase

  • Write down the 12 or 24-word seed phrase
  • Store it offline (NOT on your phone or computer)

Step 4: Confirm Your Recovery Phrase

  • MetaMask will ask you to re-enter it to ensure it's saved correctly

Step 5: Wallet is Ready

  • You can now receive, send, and store ETH, ERC-20 tokens, and NFTs

✅ Pro Tip: Connect your wallet to Token Metrics to explore trading signals, moonshots, and AI analytics directly.

Option 2: Creating a Cold Wallet (e.g., Ledger Nano X)

Step 1: Buy a Ledger or Trezor device

Step 2: Install Wallet Software

  • Download Ledger Live or Trezor Suite

Step 3: Set Up Device and PIN

How to Store Cryptocurrency Safely in 2025 | Hot vs Cold Wallets

Token Metrics Team
6 min
MIN

Cryptocurrency offers unmatched freedom, but with that freedom comes responsibility—especially when it comes to how to store cryptocurrency securely. Unlike traditional banking, crypto is self-custodied. If you lose access to your wallet, your funds are gone forever.

This guide explains everything you need to know about storing crypto in 2025, including:

  • Why crypto storage matters
  • Types of crypto wallets
  • Hot wallets vs. cold wallets
  • Tips for securing your assets
  • How platforms like Token Metrics can help protect your investment

đŸȘ™ Why Is Storing Cryptocurrency Important?

When you buy crypto—whether it’s Bitcoin, Ethereum, or a promising moonshot altcoin—you receive private keys that give you access to your funds. Anyone with that key can spend your coins.

That’s why safe storage is critical. Without it, your assets are vulnerable to:

  • Hacks and phishing scams
  • Lost devices or forgotten passwords
  • Exchange collapses or rug pulls

You are your own bank, and your security strategy is your vault.

🔐 What Is a Crypto Wallet?

A crypto wallet is a digital tool that stores your private and public keys. It lets you send, receive, and manage your crypto.

There are two main types:

  1. Hot wallets – connected to the internet
  2. Cold wallets – offline and physically secured

Let’s explore both.

🌐 Hot Wallets: Convenience Meets Risk

Hot wallets are always online, making them easy to use for trading, DeFi, or daily transactions.

Types of Hot Wallets:

  • Web wallets (e.g., MetaMask, Trust Wallet)
  • Mobile apps (e.g., Coinbase Wallet, Phantom)
  • Desktop wallets (e.g., Exodus, Electrum)

Pros:

  • Quick access to funds
  • Easy integration with DApps and exchanges
  • Great for beginners and active traders

Cons:

  • Higher risk of hacks, malware, and phishing
  • Device or browser compromise can expose keys

Best Practices for Hot Wallets:

  • Use 2FA (Two-Factor Authentication)
  • Never store large amounts
  • Double-check URLs to avoid fake websites
  • Avoid public Wi-Fi while transacting

🧊 Cold Wallets: Ultimate Security

Cold wallets are offline storage solutions, ideal for long-term investors or large holdings.

Types of Cold Wallets:

  • Hardware wallets (e.g., Ledger Nano X, Trezor)
  • Paper wallets (QR code + private key printed on paper)
  • Air-gapped devices (old smartphones with no internet access)

Pros:

  • Immune to online hacks
  • Best for HODLing and large sums
  • You own full control

Cons:

  • Less convenient for daily use
  • Loss or damage without backups = permanent loss

Best Practices for Cold Wallets:

  • Buy hardware wallets directly from the manufacturer
  • Backup your seed phrase on metal plates or offline storage
  • Keep backups in secure, separate locations

🔄 Custodial vs. Non-Custodial Wallets

🏩 Custodial Wallets

Managed by exchanges (e.g., Binance, Coinbase). You don’t own the private keys.

Pros:

  • Easy to use
  • Ideal for beginners

Cons:

  • Not your keys, not your crypto
  • Vulnerable to hacks or platform failures

🔓 Non-Custodial Wallets

You own the keys. Wallets like MetaMask, Trust Wallet, or hardware devices.

Pros:

  • Full control and ownership
  • Safer long-term storage

Cons:

  • Losing your seed phrase = permanent loss
  • Requires more responsibility

Tip: Token Metrics recommends non-custodial wallets for storing long-term holdings and moonshot tokens.

🔐 How Token Metrics Enhances Crypto Security

1. Identifying Safe Assets

Token Metrics gives you AI-generated grades for tokens—helping you avoid scams and invest in credible projects worth storing long-term.

2. Trading Tools with Wallet Integration

🧠 Tips to Keep Your Crypto Safe in 2025

✅ Use Hardware Wallets for Large Amounts

Your long-term Bitcoin, Ethereum, and moonshot tokens should live on a hardware wallet, not on an exchange.

✅ Store Your Seed Phrase Offline

Do NOT keep your recovery phrase in Google Docs or your phone. Use metal seed phrase storage or write it down and lock it in a safe.

✅ Use Multiple Wallets

Diversify storage:

  • Hot wallet for daily use
  • Cold wallet for savings
  • Separate wallet for DeFi

✅ Avoid Suspicious Links and Apps

Phishing is the #1 crypto threat. Double-check URLs, don’t sign unknown transactions, and avoid shady browser extensions.

✅ Monitor Wallet Activity

Use platforms like Token Metrics Alerts or Etherscan to track your wallet and get notified of suspicious activity.
