I've recently realized that the biggest difference between grid/DCA and a single trade isn't profit, but whether you can sleep well or not... The thrill of a single trade is very addictive, and once the narrative takes hold, you want to rush in. As a result, the first thing I do when I wake up in the middle of the night is check the K-line on my phone, feeling like my heart is being squeezed by MEV.

Grid/DCA is like installing an emotional shock absorber for yourself; when prices go up, you won't get carried away, and when they fall, you won't panic. Anyway, I buy slowly according to plan, and my sleep quality has noticeably improved.

To put it simply, choosing which one depends on whether you can accept the two pains of "possibly missing out" and "possibly retracing."
Like the recent NFT royalty debate, it's the same issue: creators want stable income, the market wants smoother liquidity, and in the end, no one is too comfortable...
Right now, I prefer to prioritize sleep first; don't exhaust yourself chasing profits.
