Just finished practicing yoga and came back to check the market, casually digging up the "tax declaration" pit again... I really got overwhelmed by transaction records at the end of last year. Now I try to fix one day each week to: deposit/withdrawal screenshots, on-chain transfer hashes, exchange transaction details, manual notes (why bought, why sold) all in the same folder. Otherwise, when calculating costs and reconciling, my mind goes completely blank. The small amounts bouncing back and forth on-chain are even more troublesome, especially recently with everyone complaining about miner/validator income and MEV causing unfair sorting. When the transaction price and actual slippage are pulled apart, incomplete records make it even harder to explain. Anyway, I’ll keep the "evidence chain" intact first. As for how to report specifically... I’m still learning and adjusting as I go, better not wait until the end of the year to tough it out.
