Lately, I've been going through a bunch of on-chain and exchange transaction records, and I suddenly feel a bit anxious: if I really need to do tax reporting or pay taxes at the end of the year, it’s not about whether I made money or not, but whether I can clearly explain “where this came from and where it went.” Now I force myself to leave a trail every time I change positions: transaction hash, time, and a few notes about the purpose. I export the trades from the CEX and save them monthly, instead of waiting until the last day to search for screenshots across the entire network—that’s too exhausting.

By the way, I see Layer 2s arguing every day about TPS, fees, and subsidies. They claim it’s a performance race, but on-chain it’s really just a bunch of addresses jumping back and forth across different bridges, with even more fragmented records… I’d rather use fewer chains and not turn my transaction history into a puzzle just to save a few bucks in fees. As for optimization? First, keep your records clean.
