Sizing in Coins, Not Contracts

Because a bitcoin lot is one coin, the math is refreshingly direct: your position in coins is your dollar risk divided by the dollar distance to your stop. Risking $100 with a $2,000 stop means 0.05 BTC. Most brokers accept fractional lots, so you can size precisely rather than being forced up to a whole coin.

Bitcoin volatility is high and it never closes, so a position can move a long way while you sleep or over the weekend. Size smaller than you would on a forex pair for the same account, and let the stop, not a bigger position, do the work of capturing the move.

quiz Frequently Asked Questions

How do I size a Bitcoin trade by risk?expand_more
Decide how many dollars you are willing to lose, then divide that by the dollar distance to your stop. The result is your position in bitcoin. Risking $100 with a $2,000 stop is 0.05 BTC.
What does 0.1 lot mean in BTCUSD?expand_more
For most brokers, 1 lot of BTCUSD is 1 bitcoin, so 0.1 lot is 0.1 BTC. A $1 move in price is then worth $0.10 on that position. Confirm your broker contract size, as a few differ.
Does leverage change my position size?expand_more
No. Leverage changes the margin required to hold the position, not the risk-based size. Your position size comes from your stop distance and risk amount; leverage only affects how much deposit the broker holds.
