We are used to it. Going back to $5k or even $3k at this point doesn't mean anything to me other than "cheap coins". We already survived it once, we can do it again.
If we drop to $3,000 I will honestly put every single penny I have into bitcoin. I’m already way too heavily (for most people) invested in bitcoin but I will put my emergency fiat stash into bitcoin (which I said I’d never do).
I hope you would. I hope I would too. But from experience I suspect we would be sick to our stomachs with fear. It is astonishingly contagious at such times.
Let us hope that we muster the fortitude to take advantage of opportunities when they come.
