Every year during tax season I regret it: why don’t I keep my trading records clean on a regular basis… especially with on-chain swaps, cross-chain transfers, and airdrops, the final reconciliation is a nightmare.

Now I’m a bit simpler but more worry-free: for large deposits and withdrawals, I take a screenshot first + note a line (time, chain, wallet, purpose), export files from exchanges and wallets monthly and upload them to cloud storage, with filenames like “2026-05_gate/on-chain_walletA,” so I don’t have to flip through everything at the end of the year.
For those on-chain small swaps, I only focus on key points: deposits, withdrawals, cross-chain transfers, and the few transactions related to converting coins into fiat currency.
The rest I summarize with tools, at least enough to explain clearly.

Recently, everyone’s been complaining about miners/validators eating MEV and unfair ordering, and I resonate a bit: if you set a small slippage, you often fail; if you set it large, it’s like giving money to others…
So now I prefer to also note down the “expected slippage/failure reasons,” so that later tax authorities won’t ask why my costs look like this and I can’t even answer.
Anyway, keeping records like a ledger makes my mindset much more stable.
Talk again next time.
