Recently, people in a certain region have been discussing raising taxes and tightening crypto compliance again, and the small psychological expectations around cash-in and cash-out have been directly exploited. To put it simply, the thing most likely to fall apart at the end of the year isn’t the market—it’s realizing you can’t even figure out whether you actually made a profit.

I’ve got one dumb method right now: every time I switch exchanges or switch wallets, I quickly export a copy of the transaction records, and the file name includes the date; keep a screenshot of on-chain transfers, including the hash; for OTC/cash-in and cash-out via fiat, toss the reconciliation statements into the same folder. Don’t say it’s a hassle—once it comes time to file reports or explain yourself, missing even one record can drive someone crazy. Anyway, I’m not going to be the bag-holder, and I don’t want to be the person who gets “educated by back taxes,” so I’ll stick with this for now.
