I do not recommend that you sell your house.
If Op will sell his house in order to buy Bitcoin, this is a bad move. There is no way you can invest in things that are too important to you. The risk is too high. Smart investors always tell people to never invest in losses they cannot afford.
True it's a risk that will appear in investing very large so as a trader must be more wise again in deciding a desire especially if selling a house to invest including the worst way in my opinion.
