I now basically treat "Not freaking out at the end of the year" as a risk control indicator: if the trading records are not kept well, fixing them later is more painful than adding margin... So I simply set aside half an hour every week to export CEX data, on-chain wallet transaction flows, and screenshots of borrowing and lending positions, all into the same folder, and casually write a couple of notes (this one is repayment / this one is cross-chain / this one is a liquidation pre-coverage), otherwise I won't recognize them myself after three months.

Especially recently, there's been a lot of discussion about miner/validator income, MEV, and whether order prioritization is fair or not. Honestly, your transaction prices drift around, making reconciliation even more difficult. Anyway, I just keep evidence based on "being able to restore the original intent," even if it means storing more data, rather than doing archaeological work in my mind at the end of the year. That's it for now, anxious but useful.
