On the razor's edge: how do you guys approach position sizing on high-conviction but volatile setups?

Alright, so I've been wrestling with this a bit, and I figure this is the right room to get some seasoned perspective. I'm talking about those trades where everything lines up—fundamentals, technicals, sentiment, the whole nine yards. You're feeling good about it, really good. But then you look at the instrument, maybe something like $NVDA on a big catalyst day or a less liquid altcoin, and the intraday swings are just brutal.

My usual risk management framework, which is pretty conservative, would suggest a smaller position size due to the volatility. But then that flies in the face of the 'high conviction' part. It feels like I'm leaving money on the table by not sizing up when I have such a strong read, but also exposing myself to a potential wipeout if one of those swings goes against me just enough to trigger a stop before reversing. It's a proper catch-22, isn't it? How do you experienced folks balance the desire to capitalize on strong conviction with the inherent, often wild, volatility of certain assets? Is there a mental adjustment or a particular method you use for these specific scenarios?
