Lately, the more I think about it, I realize that the most torturous thing at the end of the year isn't the price fluctuations, but the tax reporting and those transaction records... Especially for someone like me who moves back and forth within rollups and then settles on L1, if I don't leave a trail, it's really a disaster. Now I basically do this: every time I make a large transfer, cross-chain transaction, or interact with a contract, I make a quick note (time, chain, address, tx hash, approximate purpose at the time), and then periodically export and save a record of my exchange deposits and withdrawals. On-chain, those "large transfers" and "hot/cold wallet movements" are interpreted as smart money every day, but for me, they serve more as a reminder: don’t just watch the excitement, make sure your own accounts match, or else explaining the sources and destinations later will be more troublesome. Anyway, I’d rather spend ten extra minutes now than end up questioning my life after digging through browser history at the end of the year.
