If you do that, you do mistake, because you have a house and car but you want to sell those things and you want to buy bitcoin, so what is your goal? People are doing something for a reason but in your case I think you don`t have goal because you are losing what you have even though you can earn more through investing in bitcoin world but for me is not good to sell your house to buy bitcoin because my plan is I will hold my bitcoin now because I want to buy a house and car so, in short I want to build a real investment through bitcoin.
