I am increasingly convinced that strategies are not meant to prove how smart you are, but to keep you alive and help you sleep. Previously, the "all-in" approach on the third time was okay during the day when watching the market, but at night, my brain would automatically replay K-line charts, and the first thing I do upon waking up is grab my phone—it's too exhausting. Grid/DCA is like turning down the emotional volume; the returns may not be as exciting, but at least it won't wake you up with fear.

Recently, some people interpret large on-chain transfers and unusual movements in exchange hot and cold wallets as "smart money" signals. I also look at these... but honestly, most of the time, you don't even know who the other side is or if it's an internal rebalancing. My approach is: when I see unusual activity, I take a screenshot and save it, then compare it after a few hours—don't chase the excitement of that one second. As long as it allows me to sleep well, it matches my criteria.
