Lately, I've been startled awake several times by the words "tax declaration"… In the past, I would just take screenshots after each trade as a keepsake, but when it comes to year-end reconciliation, I just break down: on-chain transfers back and forth, exchange deposits and withdrawals, those few cross-chain bridge transactions, I simply can't piece together the timeline. Now I can only be honest: every time I make a move, I casually jot down the transaction hash, time, counterparty, and why I transferred at that moment (like switching wallets / cross-chain / farming airdrops) into a spreadsheet. The exchange side then exports deposit, withdrawal, and transaction records monthly and uploads them to the cloud. Don’t expect to patch things up at the last minute at year-end; you'll really teach yourself a lesson.

These days, I also encountered that common debate about whether to migrate before or after a major public chain upgrade. I don’t care how tough the project’s words are, I first make sure I understand the path clearly: which chain I’m moving from and to, what bridge I’m using, how much I spent on fees… Otherwise, when the time comes, explaining whether it’s a migration or “sold and bought again” will be even more painful.

What I’ve learned isn’t a trick, but this: don’t fight your memory; trading is quick, but leaving traces must be even faster.
