I used to always say, "I only look at on-chain data," and I would get lazy about remembering transactions when transferring within exchanges or across chains. As a result, when the end of the year came and I needed to do account reconciliation, my brain would just crash... Now I've changed: no matter what I do, I first leave three things—time, amount/currency, and a screenshot/transaction hash at that moment; then add a one-sentence note on "what this transaction is for" (deposit/exchange/mining/airdrop/transfer to myself). To be clear, it's not for perfect tax reporting, but to avoid relying on memory to piece things together later.

Recently, hardware wallets are out of stock again, and phishing links are everywhere. It's good that my security awareness has improved: I even treat exporting statements and clicking on unfamiliar links that "look normal" as high-risk actions, and I prefer to spend an extra 5 minutes verifying addresses and domains. Anyway, keeping detailed records is better—if I don't go crazy at the end of the year, that's a win.
