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.

Cryptocurrency adoption in the UK is booming. From retail investors to hedge funds, crypto is no longer just an experiment—it’s part of a diversified financial portfolio. But in this rapidly evolving space, smart traders know that picking the right tools and platforms is the key to staying ahead.

Before we explore the best crypto trading exchanges in the UK, let’s look at the most important development in the crypto world—AI crypto trading. And there’s one platform leading that revolution: Token Metrics.

Token Metrics – The AI Crypto Trading Platform Changing the Game

While Token Metrics is not a cryptocurrency exchange, it has emerged as the best crypto trading platform in 2025 for UK investors and traders who want to trade smarter—not harder.

Token Metrics empowers users with AI-driven insights, predictive analytics, and cutting-edge data tools to identify the best crypto opportunities—before the rest of the market catches on.

🔍 Why Token Metrics Stands Out:

  • AI-Powered Ratings: Each token is scored by proprietary machine learning models across technical, fundamental, and sentiment metrics.
  • Bullish/Bearish Signal Alerts: AI alerts when a token shows early signs of momentum or reversal—perfect for timing entries and exits.
  • Moonshot Reports: Exclusive weekly research highlighting potential 10x–100x altcoins, vetted by AI and analysts.
  • Indices & Portfolios: Build thematic or risk-adjusted portfolios using automated AI indices for DeFi, AI, L2s, and more.
  • On-Chain + Social Metrics: Discover low-cap gems by tracking whale wallet activity, social buzz, DEX listings, and more.

💡 Bottom Line: Token Metrics doesn’t execute trades—but it helps you decide what to trade, when to trade, and why. Use it alongside any UK-compliant exchange for maximum edge in your trading strategy.

Understanding Crypto Before You Trade

What Are Cryptocurrencies?

Cryptocurrencies are digital assets built on blockchain technology. They use encryption to secure transactions, verify ownership, and eliminate the need for banks or central authorities. Examples include:

  • Bitcoin (BTC) – The original store of value
  • Ethereum (ETH) – Smart contracts and dApps
  • Solana (SOL), Polygon (MATIC) – High-speed chains
  • Meme coins, AI tokens, DeFi tokens – Specialized thematic plays

What Types of Crypto Trading Are There?

1. Spot Trading

Buying/selling crypto directly at current market prices. Simple and most widely used.

2. Margin Trading

3. Futures & Derivatives

Trading contracts that speculate on price movement without owning the asset.

4. Copy Trading

Follow and replicate the trades of pro traders or algorithms.

5. AI Crypto Trading

Using platforms like Token Metrics to leverage predictive AI models for smarter decisions.

Types of Crypto Trading Platforms

🏦 Centralized Exchanges (CEX)

Platforms like Coinbase, Binance, and Kraken that offer easy fiat access, trading dashboards, and custody.

🔄 Decentralized Exchanges (DEX)

Platforms like Uniswap, where you retain custody of assets and trade peer-to-peer.

đź§  Research-Driven Platforms (like Token Metrics)

Offer AI tools, analytics, and predictive insights—but don’t hold funds or execute trades directly.

Are There Crypto Indices for DeFi, AI, and Other Sectors? Exploring Thematic Index Investing in 2025

Token Metrics Team

In the fast-moving world of crypto, one of the smartest ways to invest in 2025 is by aligning your portfolio with emerging narratives. Whether it’s DeFi, AI, Memecoins, or Real World Assets (RWAs), crypto’s growth is fueled by themes—and the easiest way to capitalize on them is through sector-based crypto indices.

But are there crypto indices tailored to specific sectors?
Absolutely. In fact, thematic crypto indices are one of the hottest trends in index-based investing right now.

This article explores the most popular sector-based crypto indices in 2025, how they work, and how you can use them to build a diversified, trend-aligned portfolio.

What Is a Thematic or Sector-Based Crypto Index?

A sector-based crypto index is a basket of cryptocurrencies selected based on a specific theme or market narrative. Instead of tracking the overall market, these indices focus on high-growth areas such as:

  • Decentralized Finance (DeFi)
  • Artificial Intelligence (AI) Tokens
  • Memecoins
  • Real World Assets (RWA)
  • Layer 1 Blockchains
  • Gaming / Metaverse

Each index includes multiple tokens within that category, allowing investors to gain exposure to the entire theme without picking individual winners.

Why Sector Indices Matter in 2025

In today’s market, performance is narrative-driven. A single meme can send a coin flying, or a regulatory shift can pump RWAs. Sector indices help investors:

âś… Capitalize on trends early
âś… Avoid single-token risk
âś… Ride sector momentum without constant research
âś… Balance exposure across tokens within a theme

Instead of trying to guess which AI token will win, you can hold the AI Index and benefit from the entire trend.

Top Sector-Based Crypto Indices in 2025

Here are the most popular and best-performing thematic indices this year:

1. Token Metrics AI Tokens Index

Focus: Artificial Intelligence & Agent Economy
Constituents: FET, AGIX, GRT, TAO, NUM, OCEAN

Constituents: ETH, SOL, AVAX, NEAR, SUI, TON
Management: Passive or AI-optimized version

Constituents: AAVE, UNI, COMP, SNX, LRC

7. Phuture Custom Indices

Focus: User-created strategies
Constituents: Fully customizable
Management: On-chain rules, community-driven

Why It’s Hot:
Create your own sector index or invest in curated strategies. Fully composable within DeFi.

How to Choose the Right Sector Index

Choosing the best sector-based index depends on your goals and your belief in specific narratives.

AI vs. Passive Sector Indices

Many sector indices today are AI-powered, meaning they adjust weights and tokens dynamically based on real-time data. This is especially useful in volatile or hype-driven narratives (like Memecoins or AI tokens).

Where to Invest in Sector-Based Indices

Here’s where to find and invest in thematic indices:

  • âś… Token Metrics – Sector-specific AI indices with weekly signals
  • âś… Index Coop – Ethereum-based DeFi indices with DAO governance
  • âś… Phuture – On-chain, user-customized index strategies
  • âś… Set Protocol – Technical and trend-driven portfolios
  • âś… Centralized Brokers – Limited thematic access (e.g., Bitwise)

You can access these using fiat, stablecoins, or crypto wallets depending on the platform.

Final Thoughts: Sector Indices Help You Invest in What Matters

In 2025, the biggest opportunities in crypto are often found in narrative-driven sectors. Whether it’s AI, DeFi, Memecoins, or tokenized real-world assets, sector-based crypto indices offer:

  • Smart diversification
  • Aligned exposure to growing trends
  • Hands-free portfolio management
  • Reduced risk of picking the wrong token

For the best results, explore platforms like Token Metrics, where AI-enhanced sector indices help you adapt to the market and capitalize on breakout themes with data-backed precision.
