Grid/DCA is still a gamble, to put it plainly, it's about what you're willing to trade for sleep: trading time for certainty, or trading excitement for luck.

I've seen too many people say "long-termism" with their mouths, but their hands are all in full positions, gambling everything, staring at the charts overnight to doubt their life... then blaming the market.

I personally prefer grid/DCA a bit, not because I think it's sophisticated, but because I know I tend to be reckless.
Gradually entering and exiting at different times can at least dull emotions, and transaction fees can be calculated clearly (especially on L2, so it doesn't feel like every small move is burning money).
Recently, I've been talking about rate cut expectations, the US dollar index, and risk assets acting up together.
Anyway, I don't want to treat macro as an alarm clock that keeps waking me up.

I see complexity as an enemy: if you can lock your hands with rules, don't rely on willpower to endure.
Choose the approach that helps you sleep well, not the one that looks the most "powerful."
