It's a very bad idea. Selling your house for profits that you are not sure to get? I will never risk it. I would rather sit in my home and relax while doing all Bitcoin stuff and working hard to grow my money. As long as you are good, I think it's better to earn money in the safest way possible. Bitcoin is still not stable. Right now, it is depending on the market demands and supply and its userbase. I think, for a very unstable currency, risking your house would really be a bad idea.
