Lately, I've really been reminded by the "tax/reporting" issue: don't wait until the end of the year to review your transaction history, because flipping through it will start to make you doubt your life... My somewhat naive approach now is to take a screenshot every time I make a large trade/transfer across chains/enter or exit CEX, then write a couple of notes with the address, tx hash, and roughly what I was doing at the time, and drop it into a spreadsheet. Anyway, you'll thank yourself when reconciling accounts later. On-chain interactions are too fragmented, especially recently with those testnet incentives and points expectations making everyone frantically complete tasks. I don't know if the mainnet will issue tokens, but if you don't keep good records, it can get really messy in the end. As for small, frequent transactions, just bundle and export them monthly—that can save a lot of effort... How do you usually organize yours? My method might not be the most optimal either.
