IF I did own and love Bitcoin I would sell before the crash, and buy in at a much lower price so at the end of the day I had twice as many Bitcoin.
Personally, I think bitcoin is the best way in the world to loose money right now, and I would not hold any.
We have opposite beliefs on bitcoin. Bitcoin right now isn't a way to lose money for me thus, it's helping me to gain some financial help and help me deal with inflation.
Also, I wouldn't sell before or after the crash happens. I'm just good at holding it and no problem with whether I'll be seeing the crash again, there's no problem with that. I've even endured $20k down to $3k and the same goes for $69k to $17k. That's not a problem, everyone can endure a potential crash that you're saying might come soon.
