My biggest lesson this year wasn’t getting MEV front-run, but nearly getting myself “sent away” at year-end because of how badly I messed up reviewing the transaction records… I kept moving funds on-chain, bridging, farming airdrops, and doing deposits/withdrawals on the CEX—screenshots just weren’t enough. After a couple of months, you’ll have forgotten what that transaction was even for. Basically, there are three things: every time I do a large transaction, I make a quick note on the spot (I literally write in my notes “to whom / for what / mood at the time”); at the end of the month, I export the CEX trades and deposits/withdrawals and dump them into cloud drive; and for on-chain addresses, I use the same spreadsheet and record one row for each item as “time - chain - purpose.” Don’t count on trying to piece it all together at year-end by memory.

Recently, around the upgrade of that mainstream chain, everyone was guessing whether projects would migrate. I also marked the bridge and the new addresses in advance—otherwise, when you switch chains later, your records will basically break off in the middle… Anyway, I’d rather spend an extra 5 minutes on bookkeeping now than waste my time at 2 a.m. in December staring at explorer logs and doubting my entire life. Talk again next time.
