What are some lesser known crypto lessons or advice that people should know?

I think we all know about the general advice of HODL, buy low sell high, and DCA-ing, don’t discuss your total gains or balance, but what are things you’ve heard from others or have learned yourself that would help us all?

A few things I’ve heard: - not just DCA when buying in, but DCA out too - if you’re worried about volatility, don’t even use your full DCA on a purchase, but make an incremental buy over the next 12 hours at a certain percentage - if one of your investments tanked this year (bought in ATH for most alts early 2022 is a good example…RIP to LRC, CKB, and basically a bunch of shilled projects i aped into ????) then sell at a loss in December for tax purposes then buy back the beginning of the next year if you’re still bullish on the project long term
