Every time I see a big on-chain transfer, I can stare at it for half a day—until I remember that year-end tax filing is coming… and the first thing to break is my own transaction records. Put plainly, don’t wait until December to go back through your chat history and look up why you bought it back then. I’m using a simple “idiot-proof” method right now: every time I deposit, withdraw, swap coins, or do a cross-chain transfer, I take a screenshot on the spot and paste the tx hash into the same spreadsheet, with notes written in plain language like: “Transferred from the exchange to a cold wallet,” “Sent it to a friend,” “Accidentally swapped to another pool.” Otherwise, it’ll just be “Address A → Address B,” and how am I supposed to explain that later? I won’t be able to laugh it off.

Recently, hardware wallets have been out of stock, and phishing links are flying around everywhere—my security awareness has definitely improved, but don’t only focus on preventing theft; your records also need to protect you from forgetting. Anyway, I’ll do it this way for now so I don’t end up staring blankly at a pile of transaction logs at year-end.
