仮想通貨取引における最適なリスク%について混乱しています

It's a valid concern. While 1-2% is a good starting point, for crypto's high volatility, many seasoned traders do scale it down, especially for smaller accounts or more speculative plays. Your position sizing can account for that volatility and slippage without having to move the percentage too much.

The 1-2% rule is fine, but it's about your portfolio, not just a single trade. If you're seeing rapid moves and slippage, your position sizing is probably too large for that particular asset or exchange. Scale down the position, not necessarily the risk percentage.

That's a great question about adapting risk per trade to crypto's unique volatility. While 1-2% is standard for less volatile assets, many successful crypto traders do scale that down, or at least widen their stop-loss to account for the larger swings, which effectively reduces the position size for the same risk. Have you experimented with lower percentages to see how it impacts your mental capital?
