Recently, digging through old accounts made my eyes hurt, and I realized that the most torturous part of tax reporting isn't how much you pay, but that you don't even know when you bought or sold, or where the fees went. Now I’m very simple: every time I switch positions, I just export a record, and for on-chain transfers, I also take screenshots and note "what it's for," otherwise by the end of the year, relying solely on memory will drive me crazy. Especially now, when everyone complains about validator income and MEV causing unfair sorting, sometimes the same transaction differs by just a little before and after, and you can't even explain it during reconciliation. To put it plainly, first keep the "evidence," and emotions can be calculated later. What I regret isn't the result, but that I was too lazy at the time to organize the records properly, and in the end, I treated my positions like my pride and stubbornly endured these messes.
