Lately, in the group chat, there's been a heated debate about whether the extreme funding rates are about to reverse or if the bubble will continue to be squeezed. My first reaction isn't about the direction; it's: Have you all kept your trading records... Don’t wait until the end of the year to realize, "Which platform did I trade on last year?"

I'm quite old-fashioned now: every time I transfer funds / exchange coins / open or close a contract, I take a screenshot + export a CSV to the cloud drive, and casually add a note (what it's for, which chain, which address).
Don’t expect the platform to always let you check your history; if you really need to provide documentation, it can drive you crazy.
What I fear most isn't actually missing out on opportunities, but one day suddenly needing to report and finding that I can't even reconcile my accounts.
