Risk management basics for crypto perpetuals

The uncomfortable truth of trading is that risk management matters more than signal quality. A great strategy with poor sizing blows up; a mediocre strategy with disciplined risk survives long enough to compound. Here are the fundamentals, applied to crypto perpetuals.

1. Risk a fixed, small fraction per trade

Decide in advance what percentage of your account you are willing to lose on any single trade - commonly 0.5%–2%. This is your risk budget. It is not your position size. Position size is whatever makes your stop-loss equal to that budget.

If your account is $10,000, you risk 1% ($100) per trade, and your stop is 5% away from entry, then your position is $100 ÷ 5% = $2,000 of notional - regardless of leverage. Leverage changes your margin, not your risk; your stop distance defines your risk.

2. Let volatility set your stop, not your hope

A flat "5% stop" is too tight for a volatile small-cap and too loose for BTC. That's why MasterBitcoin signals use an ATR-based stop- distance scaled to the asset's actual recent range. A stop placed inside the noise gets hit by random wiggles; a stop placed beyond it gives the thesis room to work.

3. Respect funding and the cost of carry

Perpetuals charge funding every few hours. In a crowded long, you pay it - and over a multi-day hold it can quietly erode an otherwise correct trade. Factor funding into your expected return, especially for slower setups. (See perpetuals and funding, explained.)

4. The maths of survival

Drawdowns are asymmetric. A 10% loss needs an 11% gain to recover; a 50% loss needs a 100% gain. This is why capping per-trade risk and total exposure matters far more than catching every winner. Protecting the downside is what keeps you in the game long enough for the edge to show up.

• Cap how many positions you hold at once - correlated longs are really one big bet.
• Use a daily loss limit and honour it. Stop trading when you hit it.
• Size down in hostile regimes; the same signal is worth less when the backdrop is poor.

5. Leverage is a tool, not a strategy

Leverage amplifies both directions. A 2× position is liquidated by a 50% adverse move; higher leverage liquidates on far smaller moves, often before your stop even triggers in a fast market. Use the least leverage that lets you express the trade at your intended risk.

None of this guarantees profit - nothing does. But disciplined risk management is the one variable fully under your control. See how we apply these ideas systematically in our risk-management methodology.
