Every year during tax season, someone pretends to be dead, basically because their record-keeping is terrible all year round. Don’t wait until the end of the year to realize “which chain I swapped on and what I did on which day.” My current method is very crude: every time I make a large swap/open/close a contract, I immediately save the transaction hash, time, token amount, and a screenshot (including slippage/fees) into the same folder, and also write a quick note like “Why I did this trade.” On-chain data is public, no doubt, but if you don’t leave notes for yourself, looking back at a bunch of cross-chain/aggregator routes will only drive you crazy.

Especially recently, with extreme fee rates, everyone in the group is arguing daily about whether to reverse or keep pumping the bubble. I’m actually more worried about accidentally opening multiple positions, ending up with unclear costs, profits, and fees. Don’t blindly trust a bookkeeping tool to save you; if it misses an import or misclassifies something, you’ll spend two hours reconciling. Anyway, I’d rather spend an extra two minutes on “annoying records” during normal times than curse myself at the end of the year over a bunch of hashes.
