Every year at the end of the year, I regret: why don't I just keep my trading records neatly all along... Honestly, it's not about being afraid of being checked, but about not matching up myself. Now I've established a very simple habit: every time I make a large trade, cross-chain transfer, or earn incentives (especially those that pull TVL for new L1/L2), I immediately take a screenshot + transaction hash and put them into the same folder, along with a note saying "why I did this." Otherwise, when I go back to calculate costs and encounter those "mine, transfer, sell" back-and-forth trades, it really can drive me crazy. Anyway, I’d rather miss out on a little than spend all my life on reconciling accounts. Rely on habits in the long run, not talent.
