I found that the biggest difference between grid/DCA and a single trade is not how much you make, but whether you can sleep well at night... With a single trade, it looks satisfying during the day, but at night your mind automatically replaying "If only I hadn't added to my position just now." A few days ago, I was really tempted to just exit and uninstall the app to avoid impulsive actions.

But I held back and looked into the on-chain liquidation waterfall volume, and I realized my anxiety isn't about the market, but about having too large a position.
Basically, grid/DCA is about dispersing emotions, following the plan regardless of market rises or falls. The returns might not be as exciting, but at least you don't have to rely on willpower to endure. Recently, everyone has been comparing RWA and US Treasury yields with on-chain yield products. To me, it seems more like "finding a seemingly stable reason to keep holding," but whether it's stable ultimately depends on whether you can accept the drawdowns.
Anyway, I now prefer to go slower rather than wake up in the middle of the night to top up my margin.
