I've been diving for a long time, but I still want to say: grid/DCA versus all-in, honestly, it's not about the strategy, it's about whether you can fall asleep. Going all-in feels great during the day, but at night, my mind automatically replays everything until dawn; for someone like me who treats holdings like a potted plant, I prefer to water it slowly, prune regularly, take some profits when it rises, and add a little when it falls, so my emotions are less likely to take me away.

Recently, everyone has been interpreting ETF capital flows, US stock risk appetite, and crypto market rises and falls together... It's not that they're wrong, but hearing it too often makes my hands itch. Anyway, my bottom line is: any impulse to just "go all in," I first turn off the screen and go to sleep. Only positions I can sleep through are worthy of holding for the long term.
