If you have a majority of your bitcoins still in bitcoin, I would suggest not to quit your job yet. It could turn around just as fast, if not faster, than we got here. Don't go out and purchase fast cars, yachts and houses unless you pay it entirely in cash, and make sure you tell the tax collector so you are left over with no debt at all. You don't want to be the one who literately ends up considering suicide because a stock or something similar you bet everything on collapsed. You don't want to be that guy.
