Recently, I've seen a bunch of people watching on-chain large transfers and exchange hot and cold wallet movements, saying "smart money is moving"… I also take a glance, but honestly, it's more like noise. Following it around will just ruin my sleep.

Grid/DCA (Dollar-Cost Averaging) is just a solid approach for me: splitting up my positions, diversifying across chains, so that when prices fall, I don't cut to the bone, and when they rise, I slowly eat the gains.
Jumping in all at once sounds exciting, but you have to accept that it also drags your emotions along, and the more you think about it at night, the more uneasy you feel.

Which one suits me?
The kind that allows me to sleep peacefully.

Anyway, I now have only one principle: not relying on "understanding smart money" to prove myself, but anchoring myself with a position framework, and avoiding hero dreams. That's it for now.
