That is a pretty dumb thing to do because betting your house is way to dumb. I would never sell my house to go all in, my house is way to important and special to me to give away.
That I'm agree with, to sold house for any investment sounds just to crazy. I remember a guy from few months ago, who sold everything and put all on red ( you can fins video on YouTube ). This is totally similar story, both of them risking a lot in my opinion.
Its a thin line between crazy and dumb, this guy's are proving that. The guy on roulette had luck, he doubled his money ( he took more then 230 000 $ ), I hope OP can have also luck to double, and with btc is possible to triple his money.
