Crypto Risk Management: Position Sizing and Stop-Loss Strategy
Most traders lose not because of bad entries, but poor risk management. This guide covers position sizing, stop-losses, portfolio risk limits, and the math behind protecting your capital.
The number one reason crypto traders blow up their accounts is not picking the wrong coins — it is risking too much on any single trade. Professional traders risk 0.5–2% of capital per trade. This allows you to survive 50 consecutive losses without catastrophe.
The 1% Rule
If you have $10,000 and risk 1% per trade ($100), you can have 99 consecutive losses before going to zero — which is essentially impossible. If you risk 20% per trade ($2,000), 5 bad trades wipe you out. The math is unambiguous: smaller position sizes dramatically extend your survival time in trading.
How to Calculate Position Size
- Define your risk per trade (e.g. 1% of $10,000 = $100 max loss)
- Set your stop-loss level (e.g. 10% below entry)
- Position size = Risk / Stop distance = $100 / 10% = $1,000 position
- Adjust for leverage: $1,000 at 5x leverage = $200 collateral needed
Portfolio-Level Risk Limits
- Maximum single position: 10–15% of portfolio
- Maximum correlated exposure: 30–40% (all L1s move together)
- Daily drawdown limit: stop trading if down >3% on the day
- Monthly drawdown limit: reduce position sizes by 50% if down >10% in a month
Stop-Loss Discipline
A stop-loss that you move or ignore is not a stop-loss — it is hope management. Set your stop before entering the trade and treat it as non-negotiable. Many professional traders use time stops as well: if the trade has not moved in the expected direction within N days, exit regardless of price.
