I found that the biggest difference between grid/DCA and a one-shot trade isn't profit, but sleep quality... I stay up reviewing until dawn every day, and I'm afraid that I might impulsively open a one-shot trade, then lie in bed with my eyes wide open until sunrise, with my mind full of "Should I cut losses / Should I add to my position." Grid and DCA are like giving yourself a dumb method: buy a little when needed, sell a little when needed, even if you lose, it won't cause an emotional explosion, at least you can sleep.

Recently, during the extreme fee rate period, it was even more obvious, the group was arguing fiercely: whether to reverse or continue squeezing the bubble. I watch the capital flow while laughing and feeling a bit annoyed—some people interpret "extreme fee rate" as "I must bet on the direction," honestly, if you bet right, it's exciting; if you bet wrong, it's a sleepless night package.

Anyway, my current conclusion is very straightforward: a strategy that allows you to sleep well is the only strategy worth calling your strategy. Don't fight your body; the market doesn't give awards to insomniacs.
