This technique is a very risky one. Selling a house is not that easy. Also, you have many things to do and manage before you can sell your house. Keep in mind that not all the time, investing in bitcoin can give you a huge amount of profit in a given time. Bitcoin can also experience crash that will make its price lower and you will lose some money that you invest. For me, its depends to a person if he/she will be risky in doing this technique.
