In the past few days, I've seen people explain the rise and fall of the crypto market by mixing ETF capital flows and U.S. stock market risk appetite. Basically, just listen to the sentiment, don't get yourself cooked into it.

My own sleep experience is: grid/DCA is like... and also like... automatic renewal + scheduled watering, even with big fluctuations, I don't wake up startled in the middle of the night; a single shot is really like opening a blind box, full of excitement before opening, staring at the screen until my eyes are dry after opening.
Anyway, if you're busy during the day and only check on-chain data at night, choosing a method that makes you "forget it won't explode" is more human, earning slowly but sleeping well. Even if you lose, it's good for review, at least you're not being dragged around by emotions.
