Lately, I’ve been startled twice by the thought of “how to file taxes at the end of the year”… To be honest, I’m not afraid of losing money, but of not matching the accounts. Now, after each trade, I conveniently save: exchange transaction records, on-chain tx hash, screenshots at the time (including currency/amount/time) into a folder, named by date + notes, user-friendly for lazy people. Cross-chain transactions are even more troublesome, especially Layer 2s, which are busy arguing over TPS, fees, and subsidies, while I’m running back and forth on bridges. In the end, my wallet is filled with small residual coins scattered like punctuation, and I’ll really cry when I try to trace their sources later. Anyway, I first write a simple note explaining “why I did each action”: arbitrage/airdrop/convert to gas, leaving a clue for my future self. Auditing is romantic, tax reporting is practical, bugs are tragedies… That’s all for now.
