Recently organizing transaction records, I suddenly realized: the most frightening thing at the end of the year isn't the market trend, but the blankness of "what was I actually doing" at that time... So now I force myself to develop a habit: every time I switch chains / transfer across exchanges / make large transfers, I casually take a screenshot + TX hash and drop it into a folder sorted by month. I only record three columns in Excel: time, what I did, and approximate amount. Don't aim for perfection; just make sure the accounts match first.

By the way, I want to complain that now everyone always uses ETF capital flows and US stock risk appetite to explain all the rises and falls. Watching this makes me also itch to trade more, but thinking about recording again makes me calm down.
For safety, I am willing to take an extra step: spend ten minutes each week exporting and backing up the bills from each exchange. It's a bit troublesome, but at least it won't crash at the end of the year.
