Recently started doing "reverse shorting" for my end-of-year anxiety: keep a record of my trades if I can, otherwise I’ll really go crazy during tax season... I now basically just make a quick note after each interaction: time, chain, address, what I did, roughly how much gas, and I also save screenshots in a folder. Don’t find it troublesome—later when I need to review, it’s a lifesaver. Especially for airdrops that come suddenly, if I don’t record the moment it arrives, a couple of months later I won’t remember which chain or which task it was from.

I heard some regions are increasing taxes again and tightening compliance a bit, so I’m even less willing to be "casual" about it now. My expectations for deposits and withdrawals have become more conservative: I’d rather keep more evidence than risk not being able to explain things clearly later. There are many tutorials, but I prefer those practical ones like “you only have a bunch of wallets and exchange transaction records, how to organize them into a table,” rather than flashy ones. Anyway, first get the accounts clear—earning from arbitrage is like a salary, not like lottery tickets.
