Nope, i wouldn't sell my house for btc.Don't get me wrong but i think that every business is an adventure and its not a sure thing if your investment will be successful or not, im not willing to gamble with my house for me to invest it in btc. I could sell other stuff but never my house.
You have the right idea, selling a house for Bitcoin is not a smart move if that person is living in that house.
That would be the craziest idea ever did of a Bitcoin fanatic person. Selling a house that not only the value in it but the memories that created by the whole family in it. Most people don't sell their house for any reason unless it's really need to but selling the property to enable to invest Bitcoin is the most stupid but lucky.
