Lately, I've been really scared by tax and reporting issues... Usually, when I get impulsive, I chase small caps, transfer back and forth on the chain, and by the end of the year, when I want to supplement transaction records, my mind goes blank. Now I have a simple method: every time I make a large deposit/withdrawal, cross-chain transfer, or change wallets, I conveniently record the tx hash, time, and counterparty address on a line (a memo is fine). At the end of the month, I export a statement from the exchange and upload it to the cloud drive, so I don't wait until I need it and find out the "history only retains 90 days" trap. Especially with cross-chain bridges, which have recently been hacked; if one day the on-chain records don't match, you won't even have enough evidence to explain. And during the oracle anomaly incident, everyone kept saying "wait for confirmation," which basically means keeping more evidence so you can't be stubborn. Anyway, I now prefer to be more troublesome; otherwise, I’ll really go crazy at the end of the year... That's it for now.
