I am increasingly convinced that whether grid/DCA is really good or not depends on whether you want to sleep well... I understand the thrill of gambling, but frankly, it's more like testing your heart, not your judgment. When the market swings, the first thing I do when I wake up at night is reach for my phone, and after a while, it really takes a toll.

On the other hand, habits like grid or dollar-cost averaging, which are "slow and steady," may not be cool, but they pull you out of emotional reactions a bit: a dip isn't the end of the world, and a rise doesn't make you overly excited. Recently, I've seen some places tighten and loosen regulations, tax policies changing back and forth, deposit and withdrawal expectations fluctuating—it's easier to get emotionally unstable. At such times, position management is more lifesaving than prediction.

It's not about who has a stronger talent, but whether you're willing to cultivate a habit that can be maintained long-term. Strategies that help you sleep soundly are usually easier to sustain in the long run. That's all for now.
