Seriously? You know that it is too risky, when investing in bitcoin you're never sure of anything. Yes you're right that the price of bitcoin is currently in a big dump and it is a good idea investing but if you're going to invest you're house which means losing your house, isn't a good idea. Maybe there are still other ways to invest in bitcoin, because once you lose your house where are you living by then, I guess that will be your problem.
