Lately, digging through old accounts has become a headache, and I suddenly understand why some people want to quit the scene at the end of the year... My current method is pretty crude: every time I deposit, withdraw, exchange coins, or repay loans, I take a quick screenshot, then put the CSV exported from the exchange and the on-chain transaction hash into a folder, sorted by month. I’m too lazy to organize it neatly, so I just keep it for now—at least I can match things up later. Especially with lending pools, before and after liquidation, interest accumulation—things look like they haven't moved, but the account balances change a lot. Not keeping records would really cause chaos.

My mom asked me a couple of days ago, “Do you need to issue an invoice for your trades?” I could only reply half-heartedly: No invoice, but I keep records like a ledger...

By the way, recently there’s been a lot of noise about NFT royalties. It’s actually quite similar to tax matters: everyone wants to “reduce friction,” but when it comes to reconciliation and explanation, without proof, you’re just stuck. Anyway, I don’t decide for anyone; I can only say: leave traces first, don’t rely on memory.
