I found that the main purpose of grid/DCA strategies is not making money, but survival... at least I can sleep peacefully. Anyway, it's like automatic cat food feeding; even when the market is chaotic, someone still gives me a bite.

But if you just go all in, honestly, it's more suitable for people who say "I'm not sleeping today": from the moment you open a position, you start imagining all kinds of endings, palms sweating but still pretending to be tough.
Recently, I saw everyone complaining about miners/validators' income and MEV (front-running/queue-jumping) causing unfair ordering, and I feel even more timid: if there are queue-jumpers on-chain, why should I bother fighting myself? First, use grid to dull your emotions, leave impulsiveness to jokes.
