Recently, I saw someone shouting "Only feeling it with a full all-in," and it reminded me of a time I tried it myself.

The result was either staying up all night watching the market or waking up in the middle of the night in shock; I didn't remember the gains, but I remembered the heartbeat...
Honestly, once the position is fully committed, sleep quality becomes tied to the market, which is too costly.

Grid/DCA feels more like "reproduce first, then conclude" to me:
First run through the worst-case scenario—can I still add if it crashes, will it explode, do I need to set stop-loss?
Only open if I can handle it; otherwise, pretend I didn't see it.
It's okay if the profit is a bit less; at least the mind stays clear.

These days, that mainstream public chain is about to upgrade/maintain, and the group is guessing whether the ecosystem will move.
I don't gamble on migration plots anyway; I prefer to buy slowly with small positions, keep some ammunition, and see the actual on-chain data after the upgrade.
A strategy that allows me to sleep well is my own strategy.
