Should I use the same risk percentage for every pair?

Not necessarily. For BTC/ETH (relatively low volatility), you can use 1-2% risk. For small-cap altcoins (high volatility), reduce to 0.5-1% due to higher risk of sudden moves. I recommend an 'asset class risk multiplier': BTC = 1x, ETH = 1x, top 20 altcoins = 0.75x, top 21-100 = 0.5x, micro-cap = 0.25x.

When should I scale up position size?

I recommend two simultaneous conditions. Condition 1: 6+ months of positive performance with a consistent edge. Condition 2: Capital grows naturally due to compounding. When both are met, you can scale risk from 0.5% to 1%, or from 1% to 1.5%. Increase gradually—do not jump from 1% to 3% in one step.

Does position sizing differ for spot and futures?

Yes. Spot: max risk = 100% (if coin goes to zero). Futures: max risk = 100% (liquidation) BUT capital is consumed much faster due to leverage. My recommendation: use 50-75% of the spot risk for the same strategy on futures. Example: spot 1%, futures 0.5-0.75% per trade.

Should I compound profits (increase position size with equity)?

Yes, if you track equity weekly and update your position size formula. Each week, recalculate based on current equity. This allows long-term compounding (profit grows → position larger → more profit). However, it requires discipline because during drawdowns, position size also decreases—you must accept this.

Can I use the same formula for copy trading?

Yes. When copy trading, set a 'stop copy' at a 15-20% drawdown on total copy capital. This is position sizing layer 2—you don't control each trade but you control aggregate risk. I have a post [OKX Copy Trading Guide](/kien-thuc/okx-copy-trading-2026-huong-dan-cho-nguoi-viet-cach-chon-trader-uy-tin) — the stop loss section applies to all exchanges.
