How to Trade Bitcoin (BTC/USD): A Guide for Forex Traders

How do you trade bitcoin (BTC/USD)?

BTC/USD is the price of one bitcoin in US dollars. You can trade it in two ways: buy real coins on a crypto exchange and keep them in a wallet, or trade a CFD at a broker, which tracks the price without you owning coins. Bitcoin moves far more than currencies, so position sizes must be much smaller.

The live BTC/USD price is on our rates page, and forex vs crypto compares the two markets.

Owning bitcoin vs trading a bitcoin CFD

• Owning coins: you pay the full price and hold the asset itself, for years if you like, with no overnight charge. You only profit if the price rises, and keeping the coins safe is your job.
• Trading a CFD: a CFD, or contract for difference, is a contract with your broker that pays you the change in price. You can go long (buy, to profit from a rise) or short (sell, to profit from a fall), and you can use leverage, which means controlling a position larger than your deposit. You pay an overnight financing charge called swap.

Ownership suits long-term holding. A CFD suits short-term trading in both directions, where the law allows.

What is bitcoin? The key facts

• Bitcoin was launched in 2009 by an unknown creator using the name Satoshi Nakamoto.
• No company runs it. A network of computers keeps a shared public record of every transaction, called the blockchain.
• The software caps supply at 21 million coins. New coins are paid as a reward to “miners”, the computers that process transactions.
• Roughly every four years that reward is cut in half, an event called the halving, so new supply slows over time. Halvings took place in 2012, 2016, 2020 and 2024.

For a trader, the key point is that bitcoin has no interest rate, economy or central bank behind it. Its price rests on belief, and beliefs change fast.

What moves the bitcoin price?

• Adoption and investment flows: buying by funds, companies and ordinary savers. Since January 2024, regulated funds that hold bitcoin directly have traded on US stock markets, and their inflows and outflows are widely watched.
• Regulation news: bans, approvals, tax rules and legal action against large crypto firms can move the price sharply within minutes.
• The US dollar and interest rates: when rates are low and money is plentiful, investors take more risk and bitcoin tends to benefit. When the Federal Reserve raises rates and the dollar climbs, it tends to suffer.
• Risk mood: so far bitcoin has mostly behaved like a risk asset, falling together with shares on fearful days. Our guide to risk-on and risk-off explains the pattern.
• The halving story: past halvings were followed by strong rallies, and many traders expect a four-year cycle, but a handful of halvings is far too few to prove a pattern.
• Large holders: a small number of wallets, called “whales”, hold a big share of all coins, and one large sale in quiet hours can move the price sharply.

How volatile is bitcoin, and how do you size a trade?

A major pair such as EUR/USD typically moves well under 1% on a normal day. Bitcoin can easily move 3% to 5% in a day, and moves of 10% or more have happened many times. It has lost more than half its value several times, and more than 70% in its deepest falls. The ATR (average true range) indicator shows the average daily range in dollars, and our position sizing guide explains the method.

At many brokers, 1 lot of BTC/USD is 1 bitcoin, so a $1 move in price is $1 per lot, and the minimum is often 0.01 lots. Check your broker’s contract specification. Suppose you have a $5,000 account and risk 1%, which is $50. Bitcoin is at a hypothetical $50,000, the daily ATR is about $2,000, and you place your stop-loss, the order that closes a losing trade, $2,000 away.

• Risk per lot: 2,000 × 1 BTC = $2,000.
• Position size: 50 ÷ 2,000 = 0.025 lots, rounded down to 0.02 lots.
• Actual risk: 0.02 × 2,000 = $40.
• Position value: 0.02 × 50,000 = $1,000. At 2:1 leverage the margin, the deposit your broker holds, is $500.

The position is worth only a fifth of the account. To a forex trader that feels tiny, but it is right. The trader who types 0.50 lots out of habit holds a $25,000 position, and the same $2,000 move costs $1,000, or 20% of the account. The position size calculator includes BTC/USD.

Bitcoin trading hours and weekend gaps

Bitcoin itself trades 24 hours a day, every day of the year. Some brokers quote bitcoin CFDs all weekend; others close on Friday night and reopen on Sunday or Monday. When a closed market reopens, it does so with a gap, a jump from Friday’s close to a new price, and a stop-loss inside the gap is filled at that new price.

At weekends liquidity is thin: fewer buyers and sellers, wider spreads and exaggerated moves. Either close before the weekend or hold a size that survives a large gap. In the example above, a 10% gap is $5,000 per coin. On 0.02 lots that is $100, or 2% of the account.

What does it cost to trade bitcoin CFDs?

• Spread: the gap between the buy and sell price is wider than on major pairs, and it widens further at weekends and in fast moves.
• Overnight financing: usually the biggest cost, often quoted as a yearly percentage of the position’s value and charged every night. Take a hypothetical rate of 20% a year on a $10,000 position: 10,000 × 0.20 ÷ 365 ≈ $5.50 a night. Hold for 30 days and you have paid about $165 before the price has moved. Our guide to swap fees shows where to find the rate.
• Leverage caps: under EU and Australian rules, retail leverage on crypto is capped at 2:1, so you must put up half the position’s value. The UK regulator has banned the sale of crypto CFDs and other crypto derivatives to retail clients since January 2021. Rules elsewhere vary and change, so check your own country’s regulator.

Offshore brokers may offer 100:1 or more on bitcoin. With a daily range of several per cent, ordinary noise can empty such an account within an hour. Bitcoin hours and financing rates vary widely, so compare regulated brokers first.

Does technical analysis work on bitcoin?

The same chart tools apply, from trend lines to moving averages, because they measure crowd behaviour and bitcoin is driven almost entirely by the crowd. None of them predicts the price, and all fail when surprise news hits.

• Round numbers matter more: big round prices attract headlines, orders and stops, so expect false breaks there.
• Think in percentages or ATR: a $1,000 stop is wide at one price and tight at another.
• Distrust weekend breakouts: moves made in thin weekend liquidity often reverse on Monday.

Security, counterparty risk and scams

Coins left on an exchange are only as safe as that exchange. Several large ones have been hacked or have collapsed, taking customer money with them. Coins in your own wallet are controlled by a private key, usually backed up as a list of recovery words. Lose it and the coins are gone for good; anyone who sees it can take them. If you trade CFDs, the other side of every trade, your counterparty, is your broker, so its regulation matters most.

Crypto also attracts fraud: fake platforms showing invented profits, online “friends” who steer you to a trading site, giveaways that promise to double your coins, and “recovery agents” who charge fees upfront. The warning signs in our guide to forex scams apply here too.

Mistakes forex traders make when they switch to bitcoin

• Keeping the same lot habits without working out the dollar risk.
• Ignoring weekend risk and finding a gap on Monday.
• Counting bitcoin as diversification, when on fearful days it falls with AUD and shares.
• Buying because social media is excited. By then, much of the move is often over.

No method can tell you where bitcoin will go next or remove its gap and weekend risk. Forex and CFDs, including bitcoin CFDs, carry a high risk of loss, and bitcoin’s volatility can empty a leveraged account quickly. Only risk money you can afford to lose.
