Actually, everyone understands that grid/DCA is not necessarily smarter, just easier to sleep; a single trade is not braver, just more likely to be led by emotions.

The more I watch large addresses for a long time, the more I fear not the fluctuations, but the rhythm of "a trade into the exchange at midnight, routed in three segments, then withdrawn in reverse the next day," which makes people constantly wonder what they are trying to do.
Later, I simply split the positions into smaller parts, let the grid run slowly, and try not to look after setting it up; sleep quality really improves.
The blockchain game scene has been collapsing again recently, with inflation + studio output farming, and when the coin price spirals downward, many people just keep taking flying knives with a single trade and can't sleep...
Anyway, I now prefer to earn less rather than stare at K-line charts until dawn every day.
What suits you is the right strategy; otherwise, strategies end up becoming torment.
