This year's biggest fear isn't slippage, but at the end of the year, flipping through transaction records and questioning my life... I now spend 10 minutes each week taking screenshots/exporting CEX deposits and withdrawals, wallet addresses, DEX swaps into a folder, and casually jotting down "what is this for," otherwise on tax day I’d be making guesses based solely on intuition, which would drive me crazy. On-chain data, to put it simply, is all there, but scattered across a dozen addresses and multiple blockchain explorers, making it feel like archaeology to find things. By the way, I’ve also been hearing a lot of noise about NFT royalties lately, and my first reaction was: in the future, records of this secondary market will be even messier, with creator income/trading costs involved, and tax forms will probably be even more complicated... I trust data more myself, not because I’m rational, but because intuition is too easily led astray by greed, while data at least will coldly prove me wrong.
