Every year during the tax declaration season, I want to uninstall my trading software... To be honest, it's not the taxes that are the most frightening, but that you simply can't remember what you did. My simple method: starting now, set aside one fixed day each week to export all exchange transactions and on-chain transfers, organized into folders labeled "Deposit/Withdrawal/Spot/Contract/Fees," and conveniently add a note: why I entered the position at that time, where the stop-loss point was. Candlestick charts are a psychological test, and ledgers are actually the same; the less willing you are to look at them, the more it shows your position is off. (Don't ask me how I got through last year.) Recently, everyone has been complaining again about miner/validator income, MEV front-running, and unfair ordering; I prefer to also screenshot and keep those on-chain transactions, so I won't be confused at the end of the year and think I was "stolen from." Anyway, having everything recorded makes my mindset more stable.
