Every year during the reporting season, I feel like I want to cut off my own hand: why didn’t I keep my transaction records clean from the start? In plain terms, don’t expect to “fix the books” at year-end from memory—no matter how transparent the blockchain is, you’ll still get yourself confused. My dumb solution is: every time I deposit/withdraw, change chains, or farm an Airdrop, immediately throw the txhash, the time, the coin and amount, and the screenshot/notes from that moment into the same table—then tag the wallet’s purpose too (“main holdings,” “farming yield,” “testing,” that kind of human language). Recently, people have been complaining that on-chain data tools/tagging systems are lagging behind and can even mislead you, and I believe that too—so I only treat them as auxiliary. The key evidence is always what I keep myself. Tired, but still doing it. Anyway, it’s worth it if I can scold myself less in the future.
