Your post is *probably* sarcastic, and I tend to agree with this.  There's a whole bunch of shit that could go wrong, and I think selling one's house to speculate on crypto is a full-retard move.  On the other hand, if this turns out to be just a dip then this dude could strike it rich.  And you could sell your house and buy lottery tickets, too.  That would also be a boneheaded move entailing just a little bit more risk...ugh.  Don't do it.   If you're fortunate enough to own property, you should hold on to it.
