Every year during tax season, I want to hit myself: why didn't I keep my trading records well... Especially lately with all these new L1/L2 incentives boosting TVL, moving funds back and forth, mining, selling, making aggressive moves like a tiger, and then reconciling at the end of the year feels like archaeology.

My current somewhat dumb method: every time I make a large swap/ cross-chain/ claim incentives, I casually take a screenshot + write a note in my memo saying "why I did this" (rebalancing/stop-loss/arbitrage passing by), then export the exchange transaction history and on-chain addresses to a cloud drive weekly, with filenames sorted by date. Basically, it's to prevent my future self from messing with myself, avoiding the awkwardness of "I also don't know what this transaction was for." The risk is just that if I don't record well, gains and losses are hard to explain. That's it for now.
