Lately, airdrop season feels like clocking in at work, with task platforms constantly fighting against the "witch hunt," and as the on-chain records pile up, I start getting a headache just thinking about tax reporting at the end of the year... I now basically finish my run and then conveniently put all the exchange transaction records, on-chain transfers, Gas fees, and bridge transactions into one spreadsheet, keeping a screenshot as well, to avoid flipping through browsers for hours later. The turning point is: don't wait until the end of the year to fill in the gaps, you'll really go crazy; even if you think you're just "playing around," when it comes to explaining the source and destination later, honestly, these fragmented records are lifesavers. Anyway, I don't know what the most standard method is, I can only make it traceable first, at least I feel more at ease.
