Recently, while organizing my tax declaration materials, I realized that "I don't think I traded much" is basically an illusion... To put it simply, I'm not afraid of losing money, but I'm afraid that year-end reconciliation will be like archaeology. Now I just take a screenshot + export a CSV file every time I switch chains/wallets/bridge and upload it to the cloud drive, with the filename clearly indicating the time, address, and what I did; I also add a note on chain interactions, otherwise seeing a bunch of hashes after a few months can really cause amnesia. A few days ago, before and after the upgrade of that mainstream public chain, everyone guessed whether projects would migrate; I also tagged those few pre-emptive operations separately: so that later, when they migrate back and forth, the cost basis is clear. When gas is cheap, doing more "organizing" is much more reassuring than fixing things after the fact.
