Yesterday I almost laughed at myself for digging up old accounts: over the past year, cross-chain transactions, mining, airdrops, and even several CEX deposits and withdrawals, and waiting until tax season to fill in the records is just self-torture. Now I have a simple method: take a screenshot and export transaction history immediately after each big move, including on-chain transaction hash, time, currency amount, counterparty (write it if you can), and casually drop it into a spreadsheet; group wallet addresses by purpose, don’t mix them up, or else the disputes over mixed coins/privacy coins and compliance boundaries will get heated, and in the end, you’ll be the one suffering. To put it plainly, narratives can be broken down, but tax forms can’t… First, keep the evidence, so you won’t panic so much at the end of the year.
