After finishing my night run, I checked the L2 data and also took the opportunity to archive today's transaction records... Honestly, the most likely thing to cause a crash at the end of the year isn't profit or loss, but the frustration of "where did these few transactions come from" and the mismatch in accounts. Right now, I feel pretty simple: every time I cross chains / swap tokens / test the testnet, I take a screenshot + export a CSV file, name the file clearly with the date and chain, upload it to the cloud, and then note in the spreadsheet "why I did this transaction." Otherwise, with all these testnet incentives, point expectations, and guesses about whether the mainnet will issue tokens or not, I end up with a bunch of small deposits and withdrawals in my wallet, and later I can't remember what they were for.

Too much information also makes me anxious. My filtering method is simple: only look at what actually happened on the chain (fees, bridge traffic, active addresses), and treat other rumors as background noise—don't take them as evidence. Anyway, just keep good records first, so you won't have to do archaeology when the tax authorities come asking for explanations.
