Calculate the exact number of Bitcoin to buy based on your account size, risk percentage, and BTC entry and stop loss prices.
Bitcoin's volatility makes position sizing even more critical than in traditional markets. A 5% daily move is common for BTC — without proper sizing, a single bad trade can devastate your account.
BTC-Specific Considerations
Bitcoin typically trades with wider spreads and larger candles than forex or stocks. This means:
Example: $10,000 account, 1% risk, BTC at $67,000
Stop at $65,000 (3% below entry):
Stop at $66,000 (1.5% below entry):
Same dollar risk, very different BTC amounts.
Position Sizing
Calculating how much of your account to risk on a single trade to keep losses within your predefined risk limit.
Risk Per Trade
The maximum percentage or dollar amount of your account you are willing to lose on a single trade — the foundation of sound position sizing.
Stop-Loss
An order that automatically closes your position at a specified price to limit losses on a trade.
Risk/Reward Ratio (R:R)
The ratio between the potential loss on a trade and the potential profit — e.g. 1:2 means risking $1 to make $2.
Use the 1% risk rule: risk no more than 1% of your account. Divide your risk amount by the distance between your BTC entry and stop loss price to get the exact BTC amount.
Bitcoin is volatile. Day traders often use 1–2% stops, while swing traders use 3–8% stops. Wider stops require smaller position sizes to maintain the same dollar risk.
Yes. In high-volatility periods, widen your stops and reduce size. In tight consolidation, you can use tighter stops and larger size — always keeping your dollar risk constant.
