Anyone else struggle with position sizing when volatility spikes?

Hey everyone, still relatively new to trading more volatile assets like crypto, specifically $ETH. I'm finding it really tough to stick to my usual risk-per-trade when we get these sudden 10-15% intraday swings. My gut reaction is to reduce size significantly, but then I worry about missing out if it's just noise before a bigger move. How do you all adjust your position sizing strategies when volatility goes through the roof without completely sidelining yourselves?
