I suggest letting off the gas when things start to go parabolic. It's helpful to use one or some of the charts at lookintobitcoin.com to assess how overheated the market is.

At some point, it doesn't make sense to keep stacking sats, until prices fall back down to fair value.

Keep it simple, don't stress about selling the top - you'll loose so much life doing that. Yes it will fall back down to earth fast after it hits a peak or peaks. But, it falls to a bottom much higher than the starting point - you believe in bitcoin in the long term, don't you? So, you're fine. Just make a point to get rid of as much fiat debt that you might have when everybody is talking about bitcoin going to the moon, replacing the dollar, or whatever - it'll happen. If you want to trade focus on the big picture and pull out your basis if your account is 2x where you started.

Focus on what is enough, instead of how much more you think you'll need to retire early, or whatever. Seriously. Money, and even the best money, is not worth living for. You're worth more than that.
