yes there is no doubt about this you can really buy a house but i think it also depend on two thing one is that where are you going to buy a house what is the market value of that pace where you are going to buy a house and the second is that what about the are of the house, and then you can compare theses with the bicoin income and can buy a house then.
You could really buy a house but it depends on many factors. 1st , how much bitcoin do you have? What kind of house do you intend to buy? Are there merchants do offer this service? What is the price of bitcoin on that time? In fact there are really lots of things to consider though in able to buy a house with bitcoin.
If the bitcoin price is very high and you need a house, why not buy one. It is better to enjoy life.
