What Are
NFTs?

When an NFT is created (“minted”), a smart contract on the blockchain records the token's unique identifier and assigns ownership to the creator's wallet address. The contract also encodes any rules the creator set — such as royalty payments on future sales.

When the NFT is sold, the smart contract updates the ownership record to the buyer's wallet. No central authority processes this. The blockchain itself maintains the ledger.

Here's the thing: owning an NFT does not necessarily mean owning the copyright to the underlying asset. Most NFTs give the buyer a record of ownership on-chain, but the intellectual property rights usually remain with the creator unless the terms explicitly say otherwise. Read the terms of any project you are considering.

Digital art and collectibles. The original use case. Artists like Beeple sold single pieces for millions. Projects like CryptoPunks and Bored Ape Yacht Club created profile-picture collections that became cultural reference points in 2021 and 2022.

Gaming items. In some games, weapons, skins, and characters are issued as NFTs. Players own them independently of the game developer and can sell them on secondary markets. The catch is that if the game shuts down, the in-game utility vanishes even if the token persists.

Music. Musicians issue NFTs as limited editions, granting buyers exclusive access to tracks, royalty shares, or experiences. It removes the intermediary and lets artists sell directly to fans.

Event tickets. NFT tickets are verifiable, harder to counterfeit, and can be programmed so that resales generate royalties for the original issuer. Several major venues have tested this.

Real-world asset representation. Property deeds, certificates of authenticity for physical art, and financial instruments are increasingly being represented as tokens. This is a growth area but largely experimental in the UK in 2025.

Step 1: Get a crypto wallet. MetaMask is the most common for Ethereum-based NFTs. It is a browser extension. You generate a wallet address and a 12-word seed phrase. Write that seed phrase down on paper and store it somewhere secure. Lose it and you lose everything in the wallet. No recovery option exists.

Step 2: Buy ETH.Most NFT markets price items in ETH. Buy ETH on an exchange (Coinbase, Kraken, Binance) and transfer it to your MetaMask wallet. Allow 10–30 minutes for the transfer to confirm.

Step 3: Connect to a marketplace.OpenSea and Blur are the largest Ethereum NFT markets. You connect your wallet by clicking “Connect wallet.” You never share your seed phrase to do this. If any site asks for your seed phrase, leave immediately.

Step 4: Buy or bid. Fixed-price items can be purchased directly. Auctions require a bid. Every transaction requires a gas fee on top of the NFT price. Gas fees vary significantly by network congestion. Check current fees before transacting.

Step 5: Record the purchase. Note the date, the ETH paid, the GBP value of that ETH on that day, and the gas fee. This is your cost basis for future tax purposes.

Volatility. NFT prices can fall to near zero rapidly. The market dropped more than 95% by trading volume from its January 2022 peak to late 2023. Collections that sold for tens of thousands of pounds became effectively unsellable. This is not a theoretical risk.

Scams.The NFT space has an unusually high density of fraud. Common tactics include: fake marketplace websites that steal wallet credentials, impersonation of known collections, “rug pulls” where project founders take investment and disappear, and wash trading to create artificial price history. Research every project before spending.

Illiquidity. Buying an NFT is easy. Selling it at a price you want may be impossible if there are no buyers. Unlike fungible tokens, there is no order book. Each NFT needs a specific buyer willing to pay a specific price.

Technical risk.The image or file an NFT represents is usually stored off-chain (on IPFS or a company's own server). If that storage disappears, the NFT token persists but points to nothing. This has happened to real collections.

Complexity.Gas fees, wallet management, smart contract approvals, seed phrase security — there are multiple failure points that do not exist in traditional investing. A mistake in the wallet address when transferring is irreversible.

That depends entirely on what you want from them. As a speculative investment, the track record since 2022 has been poor for most buyers. The majority of NFTs purchased at peak are now worth substantially less than their purchase price.

As a way for creators to sell directly to audiences and retain royalties on resale, NFTs have genuine utility that does not depend on speculative value. The mechanism works whether the token trades for £5 or £50,000.

For gaming and real-world asset tokenisation, the technology is still maturing. The infrastructure exists. Whether it becomes mainstream remains unclear in 2026.

The short version: do not buy NFTs with money you cannot afford to lose. If the project, creator, or community genuinely interests you, the downside risk is the price you paid. If you are buying purely to flip for profit, the market has punished that approach consistently since 2022.

HMRC treats NFTs as cryptoassets. Selling an NFT for more than you paid for it creates a capital gain, subject to Capital Gains Tax at 18% or 24%. Creating and selling NFTs commercially is treated as trading income.

Most people who bought during the 2021–2022 peak are sitting on capital losses. Those losses can be registered with HMRC and offset against future capital gains. They are worth claiming.
