Don't wait until the last day to think about year-end taxes... I used to think "it's all in the exchange anyway," but when it came time to reconcile, deposits, withdrawals, token swaps, fees, airdrops—everything was a mess. Now I’m honest: for every large transaction (especially cross-chain or on-chain withdrawals), I take a screenshot or save the transaction link, then periodically export the exchange trades and fund flow records to cloud storage, with clear filenames indicating the date and purpose. Otherwise, when I see a string of hashes, I’ll just start doubting life.

Recently, there’s been a lot of focus on large on-chain transfers and abnormal movements in exchange hot and cold wallets as "smart money," but honestly, many of these are just internal rebalancing, consolidation, or risk control, and have little to do with you and me trading small amounts. But keeping records is enlightening: you might think you're just "moving bricks," but on the books, it’s a series of events. Anyway, I now prefer to spend an extra two minutes organizing regularly, rather than waiting until the end of the year, staring at a bunch of U's in and out and going crazy.
