You r crazy
After investing all your money in bitcoin what will you do. If the price down ohhh
It already went down like crazy. It's a great moment to buy some coins if you still don't own any. As for selling the house, not so much. I'd wait with that until we're on the rise again or at least hitting $12-13k.
Maybe you'll be homeless few months later if Bitcoin continue decreasing to very lower bottom. Don't invest what you can't afford to loose.
Millions of people are homeless and even more if you count those who are renting their homes. They are in fact homeless because the property doesn't belong to them. They can be thrown out if the owner decides to sell the property or just changes mind about the tenants.
The chance to become a millionaire doesn't come often and life is too short to let such opportunity pass you.
