I found that the biggest difference between grid/DCA and a single trade is not how much you make, but whether you'll wake up in the middle of the night.

Grid is like giving yourself a "cushion," so even if the market goes crazy, you can pretend nothing's wrong;
a single trade is very honest, with gains and losses directly hitting your heartbeat, to put it simply, it's suitable for those who "stick to this narrative, and admit it even if wrong."

Recently, those data tools and tagging systems on the blockchain have been criticized for being laggy and misleading,
but I think it quite reflects reality: you think you're following signals based on tags, but many times you're just following the signs others have drawn for you.
For me, the real signals are actually very simple—whether I start refreshing frequently, hesitate to add to my position, or still think about "whether to cut losses" before sleeping.
Once these appear, no matter how advanced the strategy, it's useless;
first, make sure you can sleep peacefully.
