although this possibility is low and probably won't happen. but I want to ask you. if the bear market starts next month, and bitcoin falls below 20k.
In bear market you should expect Bitcoin decrease 80% in value so from $60k to $12k if bear market starts now. It will of course not happen immediately but will take over a year time. Hopefully we will see Bitcoin price way over $60k so that 80% drop will not be so low.

I even think differently from you...
Bitcoin price won't drop more than $ 40k or around 30% from its current price. I think that the Bitcoin bear market this year is only around minus 30% or 40% of its current price.
