That is a big risk brother, i won't recommend that, even you have 85% sure that you will earn, i will never do it, because that's your assets, you can't buy back your house easily and you can't get the perfect location where all your needs and the places you are used too are on the same exact place if you will buy another house, i would recommend you do some campaigns like facebook, twitter and signature. or you can start on a small investement for trading ang make your money grow. we all know that the value of bitcoin is always volatile and if the value drops you will lost your home.
