I've really been tortured by tax reporting. On the third time, I only thought of supplementing transaction records at the end of the year, and I just broke down... Now I have a bit of OCD: every time I switch contracts/transfer/bridge, I make it a habit to put screenshots, tx hashes, and CSV exports from exchanges into the same folder, naming them by date + currency + purpose, or else reconciling at year-end feels like solving a case. For perpetual contracts, I also keep separate notes on fee rates, reasons for closing positions, and approximate liquidation lines, to avoid explaining later "why I lost money." Recently, the fuss over yield stacking in staking, that "nested doll" structure, has been intense. Honestly, the more convoluted the on-chain path, the harder it is to record retroactively—so I rely on leaving early traces. Anyway, I’ll stick to this for now, to reduce some luck-based assumptions.
