I am increasingly feeling that the difference between grid/DCA and a one-shot trade is not "who is smarter," but who is more suitable for your sleep. If you can accept being awakened by liquidation alerts in the middle of the night, with your heart pounding while watching the K-line, then a one-shot trade is fine; but if you still have to work during the day, and your social energy is low, I would rather take it slow, let the parameters turn like gears on their own, and know where I lost if I do lose.

Recently, meme and celebrity shout signals are moving attention too quickly, and beginners are most likely to catch the last wave... I find it exhausting to watch. Grid/DCA at least can fragment emotions a bit, so you're not always betting everything on one point. The only annoyance is occasional slippage and stacking fees, which nibble away at the returns a little, and that feels uncomfortable, but it's better than insomnia. That's it for now.
