I recently went through my trading records and realized that the biggest fear with taxes isn't losing money, but losing control — clearly, I can't explain what I did, and at the end of the year, I can only fill out forms blindly. My simple method: every time I cross chains / switch chains / farm new L2 incentives, I immediately record the transaction hash, time, token amount, and a screenshot of the moment into the same spreadsheet, also noting which wallet is used for what. Especially for activities that boost TVL, everyone is mining while complaining "mine, then sell," with on-chain actions so fragmented that if you don't keep track, you'll face a nightmare during reconciliation. Anyway, I now prefer to spend an extra two minutes leaving traces rather than waiting until the last day to be educated by myself.
