Recently, people keep asking whether grid/DCA or a single swing trade is better... I feel the core of this question is: do you want to sleep soundly, or do you want to fall asleep with some "stimulation"? Grid and DCA are like slow simmering, looking back at the curves they aren’t so dramatic, but people tend to be more human; a single swing trade is like treating the chart as an ECG, when it rises you think you're chosen by the heavens, when it pulls back you start doubting life.

By the way, now everyone is interpreting ETF capital flows, US stock risk appetite, and crypto market ups and downs as if they are tightly linked—I find it quite similar to "using a thermometer to predict the weather"...
It’s lively, but ultimately, sleep is still your own.
If you can only keep one habit: always write your position into a spreadsheet before adding to your position.
