I found that grid/DCA and a single trade are not about returns, mainly whether you can sleep at night.

Grid is like slow simmering, giving you a sip of soup whether it goes up or down, with less emotional fluctuation;
a single trade is like pouring tea leaves directly into boiling water, fragrant but also really hot, and the first thing I do when I wake up in the middle of the night is reach for my phone to see if I've been "educated" again.
Recently, modular and DA layer narrative developers are having a blast, but as a user like me, I still mainly look at candlesticks and wallet balances, and understanding it doesn’t mean I can sleep peacefully.
Anyway, I’ll start by writing down my plan tonight: if I can DCA, I won’t force a trade, just record it first.
