Position sizing inside crypto's wider ranges

Same formula, different inputs

The good news in crypto is that the position-sizing formula does not change. It is the same identity you used in forex. Risk per trade equals account equity times risk percent. Position size equals risk per trade divided by stop distance. Two lines of arithmetic, same on every screen-based market on earth. The bad news is that one of the inputs — stop distance — is usually a lot bigger in crypto, and if you do not adjust another input, your dollar risk balloons quietly.

Consider a $500 account. In forex you might risk 1% per trade — that is $5 of risk — and use a 30-pip stop on EUR/USD. The position-size math gives you a tidy micro position. Now bring the same trader to BTC where, to survive normal noise, your stop has to sit 2 to 3% away from entry. If you keep risk at 1% of equity, the dollar risk is still $5 — which is fine — but the position size becomes much smaller in BTC terms because the stop is wider. Many beginners try to fix this by increasing risk percent so the position size feels bigger. That is the trap.

Here is a defensible default for a $500 crypto account. Risk 0.5% per trade in crypto when you would have risked 1% in forex, simply because the typical stop is wider. That works out to $2.50 of risk per trade. It feels small. It is supposed to feel small. The win column of a small account is built one survival trade at a time. A trader who blows up on a single bad alt trade does not get to deploy the next ten setups that would have made the month.

One more refinement. If you are trading mid-cap or low-cap alts where stops can be 5 to 10% wide, that is not a place to risk a normal 0.5%. Scale risk down again. Some seasoned crypto traders use 0.25% or less on the wildest names. The pattern is consistent. As stop distance grows, risk percent has to shrink to keep dollar damage constant. The math will tell you. The discomfort of small position sizes is the price of staying in the game.

Recap. Sizing formula is identical between forex and crypto. Crypto stops are usually wider, so risk per trade should be lower — start at 0.5% on a $500 account, lower for wilder names. Same one R of risk, kept in dollar terms you can actually survive.
