Everything a complete beginner needs — from what Bitcoin actually is, to FCA rules, KYC checks, and how to make your first purchase safely.
Cryptocurrency is digital money that lives on a technology called a blockchain — a shared, public record book that no single bank or government controls.
Unlike pounds in your bank account, crypto isn't backed by a government or insured by the FSCS (the UK's financial safety net). Its value is driven by supply and demand — which means prices can rise dramatically, but also fall dramatically.
When you buy crypto, you're buying a digital asset and storing it in a digital "wallet" — either on an exchange (like keeping cash in a bank) or in your own private wallet (like keeping cash under the mattress — you're fully responsible).
Here's a plain-English guide to each coin — what it is, what it's used for, and the risks involved.
The original cryptocurrency, created in 2009. Bitcoin is designed to be digital gold — a fixed-supply store of value. Only 21 million will ever exist. It's the most widely recognised, most traded, and most regulated crypto in the world.
The world's programmable blockchain. Ethereum powers "smart contracts" — self-executing code — and thousands of decentralised apps (DeFi, NFTs, games). It's the second-largest crypto by market value and is often seen as the backbone of the crypto ecosystem.
A fast, low-cost blockchain designed to handle thousands of transactions per second. Solana is popular for NFTs, gaming, and DeFi apps. It's younger than Bitcoin or Ethereum and has experienced some outages in the past, though it has improved significantly.
XRP is designed for fast, cheap international money transfers between banks. Created by Ripple Labs, it's used by some financial institutions. XRP has faced legal battles in the US (now largely resolved) and is available on most UK exchanges.
A blockchain platform built with an emphasis on academic research and peer-reviewed development. Cardano aims to offer smart contracts and DeFi services with a focus on security and scalability. It is considered more conservative in development pace than other platforms.
Tether is a stablecoin — a cryptocurrency designed to always be worth $1 USD. Unlike Bitcoin or Ethereum, its value doesn't fluctuate wildly because each USDT is backed by reserves. It's widely used to move money between exchanges or to "park" funds without cashing out to pounds. Note that it is pegged to the US dollar, not sterling, so you still carry currency exchange risk as a UK user.
The number one cause of crypto loss isn't market crashes — it's human error and scams. Here's how to protect yourself.
If someone promises guaranteed returns or asks you to send crypto first, it's a scam. Legitimate platforms never contact you unsolicited asking for deposits.
Always enable two-factor authentication (2FA) using an app like Google Authenticator — not SMS. Use a unique, strong password for your crypto exchange.
Crypto prices can fall 50–90% very quickly. Never invest emergency funds, savings you'll need soon, or money borrowed on credit cards.
Always download apps directly from the App Store or Google Play. Fake apps exist that steal your login details. Double-check URLs before logging in.
If you use your own wallet, you'll get a "seed phrase" — 12 or 24 words. Write it down and store it securely offline. Never share it with anyone, ever.
Some UK banks block transfers to crypto exchanges. Check before you transfer. Most major banks (Barclays, Lloyds, HSBC, Monzo, Starling) allow it, but limits may apply.
KYC stands for "Know Your Customer." It's a legal requirement in the UK for any exchange or financial service to verify who you are before you can use their platform.
KYC exists to prevent money laundering, terrorist financing, and financial fraud. Under the UK's Money Laundering Regulations 2017 (MLR), any business that handles cryptocurrency must verify the identity of every customer.
This applies to all UK exchanges — you cannot legally buy crypto on a legitimate UK platform without completing KYC. Platforms that skip it are not compliant with UK law and should be avoided.
| Document Type | Examples | Required for |
|---|---|---|
| Proof of Identity | Passport, UK driving licence, national ID card | All users |
| Proof of Address | Utility bill, bank statement, council tax bill (dated within 3 months) | All users |
| Selfie / Liveness check | A short selfie video or photo to confirm you're the person in the ID | All users |
| Proof of Income/Source of Funds | Payslips, tax return, bank statements | Larger deposits |
For most everyday users. Requires basic ID and address verification. Applies to typical retail investors making normal-sized transactions.
The standard level — ID, address, and sometimes source of funds. Applied to all new customers during onboarding on any FCA-registered platform.
For higher-risk customers or large transactions. Exchanges will request additional documents such as payslips or tax returns to verify the source of your funds.
If you've ever opened an online bank account, you can do this. Here's the process, broken down into simple steps.
Pick a platform that is registered with the FCA for anti-money laundering purposes. Look for names like Coinbase, Kraken, or Gemini. Avoid platforms with no FCA registration. See the exchanges section below for guidance.
Sign up with your email address and password. You'll then need to complete a KYC (Know Your Customer) identity check — this means uploading a photo of your passport or driving licence and taking a short selfie video. This is required by UK law and usually takes just a few minutes.
UK law requires all new crypto users to complete a short questionnaire about the risks of crypto investing. After submitting, you must wait 24 hours before you can deposit any money. This rule exists to protect you from impulse decisions.
Use the UK's Faster Payments system (a standard bank transfer) to move money from your bank to the exchange. This is usually instant and free. Start small — only invest what you can afford to lose entirely.
Search for the crypto you want (e.g. Bitcoin or BTC). Use an "Instant Buy" or "Market Order" if you want the current price, or a "Limit Order" if you want to set a specific price to buy at. Your crypto will appear in your exchange account immediately.
For small amounts, keeping your crypto on the exchange is fine. For larger amounts, consider moving it to a personal hardware wallet (a physical device like a USB stick) for extra security. If you lose access to your own wallet, your crypto is gone forever — there's no "forgot password" option with your own wallet.
Always use an FCA-registered exchange. You can verify any platform on the FCA Financial Services Register at register.fca.org.uk.

HMRC is clear: crypto profits are taxable. Many beginners miss this — here's what you need to know.
When you sell, swap, or spend crypto, any profit you make above your annual CGT allowance (currently £3,000) is taxable. The rates are:
Some crypto activity is treated as income rather than a capital gain:
