Most common and sometimes I adhere
Collect BTC at Deep Dips. (recently FTX collapsed)
Collect potential Alts Bear market.
My favorites are the winning strategies the OP outlined. I have been using these strategies for some time now, and I have absolutely no regrets.
I would also like to emphasize that during a FUD, the individual should always follow their instincts and not the herd. Never investing money, you cannot afford to lose is a terrific winning formula that has survived the test of time.
