Last night, looking back at old records, I got a bit scared: at the beginning of the year, to save effort, I dumped all the records of multiple currency exchanges, cross-chain transfers, and withdrawals to exchanges into different apps, thinking "I'll just check the balance later"... As a result, now I want to go through them in chronological order, and I almost broke down. Later, I forced myself to set a rule: every time I make a move, I export the exchange transaction history and save a hash on the blockchain, and note down "why I did this" (otherwise, by the end of the year, I’ll just have a bunch of addresses I can't understand). Recently, everyone is watching large transfers on the chain and the movements of hot and cold wallets as smart money, I also watch, but what I fear more is being "smart" and getting carried away, ending up unable to explain tax filings. I’d rather operate less, and first keep the records in order.
