I found the difference between grid/DCA and a single shot, basically it's "Do you want to sleep peacefully or take a risky thrill." Winning with a single shot is of course exciting, but you have to withstand the adrenaline rush + the torment of itchy fingers wanting to add or cut positions midway; grid/DCA is like putting a safety rope on yourself, it may not make the most profit, but it greatly reduces emotional fluctuations, and you can still get up the next day.

For me, the "signal" is actually very simple: can I avoid watching the market and feeling anxious? If every price fluctuation makes me start scrolling my phone, then don't pretend, it means your position is too heavy, and it's better to reduce leverage, split into DCA, or use grid to let the rules control the rhythm.

Recently, everyone has been complaining about MEV, unfair ordering, and so on, I also feel strongly... In such times, I don't want to entrust my fate to "a perfect transaction." Anyway, I prefer to go slower, pay a bit more in fees, take fewer hits, and not wake up to find myself capsized in the waves.
