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.
That is the worst possible because it is too risky to sell the house. The price of cryptocurrency is quite difficult to predict. Better to use safe way. Home is an asset, do not risk the asset to get another asset that is uncertain future.
I think that is not a good idea. Where did you live if you sell your house, that is the worst dicession that you made in your life. Investing is need how many month to earn.
