Recently, while organizing my trading records, I realized that this is like making tea: when it's hot, I ignore it; if I leave it for a long time, it becomes so bitter that I question life. Now I basically export a copy of exchange transactions, deposits and withdrawals, and on-chain transfers every weekend, put them into the same spreadsheet, and note "grid rebalancing / position swapping / airdrop related," so I don't have to stare at a bunch of hashes at the end of the year. Especially during the period when new L1/L2s were incentivizing to boost TVL, moving assets back and forth, mining, selling, and other operations—I'm not sure how to classify it for tax purposes, but incomplete records would definitely be worse. Anyway, keeping good evidence helps keep my mindset steady.
