House price varies hugely depending on location.
In the city I live, I am very confident that I cannot buy a house with just 1 BTC during my lifetime as the housing price is crazy. A nice 100 m^2 apartment (forget about "houses", which are even crazier) currently costs over 4000 BTC

How long until we can trade a house for a single bitcoin??
1 year, 2 years, 3 years?? What do you think about it?
That means the price of the bitcoin has to increase 4000 times. If the price rises 100% a year, it will take 12 years.
