I don't think this is a good idea for you to sell your house and buy bitcoin because you still need a house to lived and where do you want to live with your family for doing this, you are gambling with your house and like everybody said, it is too risky to do that, it is better to try to make money with the funds you have. If bitcoin can go this much down then it is also possible that it can go much more down. It is having a high risk. So think about it again and plan smartly.there were people that did this when we were lower than this and then I hope they sold when we reached an ATH, it can work out but is really risky especially if you have family thrown into the mix for me im not gonna sell my house.
