I've always thought that grid/DCA is more like "buying an insurance that lets you sleep," especially when you still have to work during the day and look at a bunch of audit reports, you really don't have the energy to watch the market.

On the other hand, going all-in on a single shot isn't impossible, but that kind of excitement is exchanged for sleep; only those who can withstand drawdowns and resist the urge to tweak plans in the middle of the night are truly resilient.

Recently, the "compound yield" of staking and shared security has been criticized as a copycat, which is actually quite similar to the mentality of going all-in: it looks tempting to keep stacking, but the risks also pile up layer by layer.
Many people don't take the "worst-case scenario" seriously. (I get it, seeing APY makes your eyes light up.)

My personal rule: if DCA can solve your anxiety, don't force leverage;
if you really want to go all-in, don't forget to carefully check authorization, limits, and signatures—don't lose money in the market before losing it on careless confirmations.
That's all for now.
