Today, the rain is making me a bit lazy, and the coffee on the table has gone cold... I casually looked through my trading records and suddenly remembered the end-of-year tax reporting chaos that drives me crazy. Honestly, the worst part isn't the profit or loss, but the fact that I completely can't match "when I swapped what, and what was the cost."

Right now, I have a rough method: every time I cross-chain/convert tokens/claim airdrops, I take a screenshot + export a transaction history from the exchange, then just put the tx hash on a spreadsheet and add a quick note in plain language (what it was for, roughly what my mindset was at the time). For stablecoins, especially when there are regulatory, reserve audits, or rumors about "de-pegging" circulating in groups, I make sure to note it down. Otherwise, looking back at a bunch of inflows and outflows that look like a washing machine makes it impossible to explain... Anyway, I keep the evidence, to reduce the chance of luck.
