Bookkeeping is really a headache every time the year-end comes around. I used to think that keeping a general ledger was enough, and that I could just do the totals at year-end based on buys and sells—until that wave of bridge hacks messed everything up: on-chain records got completely chaotic, exchange statements didn’t match wallet transaction history, and I ended up crying while filling in missing documents. Now I’ve learned my lesson. For every transaction, I store the tx hash, timestamp, and gas fee right away. Even if a cross-chain bridge or oracle reports abnormal pricing, I can still trace back exactly what happened during the “awaiting confirmation” period using the original data. Bottom line: don’t trust that “already synchronized” icon in your wallet. Keeping your own txt or csv is more reliable than anything. Newcomers often think bookkeeping is just “how much I bought and how much I sold,” but what you really need to keep are the transaction links and an on-chain evidence trail—otherwise when an audit asks, you won’t be able to explain clearly. For now, that’s it. I’ll organize it again before the year ends.
