Every year during tax season, I want to revert to my primitive self who only holds coins and does nothing... Basically, it's hard to keep track of transaction records, and by the end of the year, it's a hellish mode of browsing browser history and flipping through group chat screenshots.

Now I’m just being simple but effective: separate on-chain addresses by "purpose" (one set for lending, another for incentives), and each time I cross protocols or chains, I conveniently note down a line: time, tx hash, what I was doing at the time (adding to position/repayment/ swapping collateral), then toss in the CEX deposit and withdrawal records into the same table.
The new L1/L2 incentives that pull TVL need to be tracked clearly; after mining, selling, and flipping back and forth, if the costs and benefits aren’t clear, it’s really hard to calculate.
Next time, I plan to dedicate a fixed 10 minutes weekly for archiving.
Do you use spreadsheets or some other tool that’s more convenient?
