How Much Money Do You Need to Start Trading Crypto in the UK?
The short answer: you can start learning for £0, and many UK apps let you buy crypto with small amounts. But the amount you can sensibly trade comes from one rule: never risk more than about 1% of your account on a single trade.
- £0: enough to learn and practise on a demo account.
- £100 to £250: enough to buy crypto in small amounts, but fees take a big bite.
- £500 to £1,000: where the 1% rule starts to give you trades that fees don't swallow.
- Any amount: only money you could lose completely without it hurting your life.
Start with £0: learn first, then practise
The cheapest losses are the ones you make with pretend money. Before you put in a penny, learn how to read a chart, where to put a stop loss and how big each trade should be. Then practise on a demo or paper trading account until you can follow your own plan for a few weeks in a row.
Our free 10-lesson course covers all of it, and you can practise trades with pretend money in the trade simulator.
The 1% rule decides your trade size
Professional traders think about how much they could lose on a trade, not how much they could make. A common rule is to risk no more than 1% of your account on any one trade. That way a run of ten losses in a row costs you about 10% of your account, not all of it.
| Account size | Most you'd risk per trade (1%) |
|---|---|
| £100 | £1 |
| £250 | £2.50 |
| £500 | £5 |
| £1,000 | £10 |
| £2,000 | £20 |
Your risk is not the same as your trade size. The trade size comes from your risk and how far away your stop loss is:
Position size = amount you risk ÷ distance to your stop
Learn this properly in Where to put your stop loss and Risk to reward.
Crypto: what £500 looks like
Crypto is our main focus at Trade Blocks, and it is also the simplest place to see the maths, because most UK beginners buy coins outright on an exchange with no borrowing.
Account: £500, so 1% risk is £5.
Plan: buy Bitcoin with a stop loss 4% below your entry.
Position size: £5 ÷ 4% = £125 of Bitcoin.
If price falls 4% and hits your stop, you lose about £5 plus fees. You don't need to put your whole £500 into one trade to trade properly.
Now try the same with a £100 account. 1% is £1, so a 5% stop gives you a £20 position. If the app charges you a £0.50 fee to buy and another to sell, that's £1 in fees, as much as your whole planned risk. That's why very small accounts struggle, and why it pays to check fees before you sign up.
Two UK points worth knowing about crypto:
- Use an FCA-registered firm. Crypto firms have to register with the FCA for anti-money-laundering rules. That's a minimum, not protection: most crypto isn't covered by the Financial Services Compensation Scheme if something goes wrong. Check any firm on the FCA Register first.
- No crypto CFDs for retail. The FCA bans the sale of crypto derivatives to retail customers, so in the UK you'd usually buy the coin itself. Since 8 October 2025, UK retail investors have also been able to buy crypto exchange-traded notes (ETNs) listed on a UK recognised investment exchange, though these aren't FSCS-protected either.
Forex and gold: smaller deposits, bigger risks
In the UK, most people trade forex (like EUR/USD) and gold (XAU/USD) with spread bets or CFDs. You don't buy the currency or the gold. You trade the price movement, usually with leverage, which means you can open a position worth much more than your deposit.
FCA rules limit how much leverage retail customers can use: up to 30:1 on major currency pairs and 20:1 on gold and major stock indices. Providers must also close your positions if your money falls to half the margin needed, make sure you can't lose more than your account balance, and show you the percentage of their retail accounts that lose money. Check that number before you sign up. It's usually the majority.
The 1% rule works the same way. With spread bets you choose a stake in pounds per point:
Forex: risk £5 with a stop 25 pips away on EUR/USD. £5 ÷ 25 = a stake of £0.20 per pip.
Gold: risk £5 with a stop 15 points away. £5 ÷ 15 = a stake of about £0.33 per point.
How much a "point" is worth depends on the provider, so check their contract details. If their smallest stake is bigger than your maths allows, the trade is too big for your account.
The costs that eat small accounts
- The spread: the gap between the buy and sell price. You pay it on every trade.
- Trading fees or commission: a fixed or percentage charge each time you buy or sell.
- Overnight funding: spread bets and CFDs usually charge you for holding leveraged positions overnight.
- Deposit, withdrawal and currency fees: small charges that add up, especially on £100 accounts.
Before you trade with real money, work out what a round trip (buying and selling) would cost on your normal trade size. If it's a big share of the 1% you're risking, either trade less often or wait until your account is bigger.
A sensible way to start
- Learn the basics for free. Charts, trends, support and resistance, stop losses and position sizing.
- Practise for at least a few weeks with pretend money. Keep a trading journal from day one.
- Decide on an amount you could lose completely without it affecting your bills, savings or sleep.
- Risk about 1% per trade and set a stop loss on every trade, before you enter.
- Review your journal every week and only add more money once you're following your plan.
Questions people ask
Can I start trading crypto with £100?
Yes, many UK exchanges let you buy small amounts. But with the 1% rule you would risk about £1 a trade, and fees can eat a big share of trades that small. Many beginners spend the first few weeks on a demo account and add money once they have a plan.
Do I need money to learn to trade?
No. You can learn chart reading and risk for free and practise on a demo or paper trading account with pretend money.
Can I trade crypto CFDs in the UK?
Not as a retail customer. The FCA banned the sale of crypto derivatives, including CFDs, to retail consumers in the UK. Most beginners buy crypto outright on an exchange instead.
Is forex or gold cheaper to start with than crypto?
In the UK, forex and gold are mostly traded with spread bets or CFDs, which use leverage. You can open a position with a small deposit, but leverage makes losses grow just as fast as gains, so the 1% rule matters even more.
