Grid/DCA and going all-in, to put it plainly, is like buying "sleep quality." For someone like me who cancels orders as easily as breathing, my biggest fear isn't losing money, but waking up in the middle of the night to a margin call notification triggered by a needle prick, with trembling hands. Grid/DCA at least breaks down the rhythm; if the market gets chaotic, I can still manually tighten the grid or modify orders, and losses happen gradually; going all-in tests your faith too much, especially when faced with sudden on-chain congestion and slippage, as the execution details can completely crush your mindset.

Recently, AI Agents and automated trading are being hyped up, and indeed some people use them as an excuse for "not watching the market," but I care more about how they sign, how much permission they grant, and how failures and rollbacks are handled... Anyway, I prefer to go slower, as long as I can sleep peacefully.
