Recently reviewing transaction records, I sincerely advise: don't wait until the end of the year to check your wallet, it can really drive you crazy... Now I just put the txhash into a spreadsheet after each interaction/exchange, and note down "why I did it/which address I used/is it mainnet or testnet" at the same time, otherwise in a couple of months you won't remember what the airdrop was for. Multi-address users are even more troublesome; I directly split sheets by "address - purpose," and also keep track of costs (gas, bridge fees, slippage on swaps), so at least I have a clear idea. Recently, a bunch of AI agents/auto-trading tools have been hyped up, but I prefer to leave my own traces + export regularly—giving too much permission can lead to messy records, and if the tax forms and security issues blow up together, it would be awkward. Anyway, just spend 10 minutes every Friday tidying up, to avoid pulling an all-nighter at the end of the year.
