I also have the same question, what if the bitcoin price goes down ? You will not only be for 2 months on the streets, but it may take longer or forever. Indeed we know that bitcoin prices continue to goes up, but it's too risky to sell house for investment in bitcoin because bitcoin prices is unstable. I certainly will not try your technique, I better start a small capital investment that is set aside from my salary every month. It's safer and I don't have to live on the street
