How awesome it would be to buy a nice house outright with BTC.
Well, there's one for sale in Alberta/Canada directly in BTC! But yes, it would be really nice to have enough BTC to cover for the price of a house.
What I would do though, is put a cash down on the house, and take a regular mortgage. Then, just cap out on the maximum allowed each year. Of course, there will be interest, but I'll keep BTC making probably a lot more than buying a house in full. Unless of course BTC end up valuing a lot more than a house, and that would represent a fraction of my total BTC
Imagine in a few years, where 1 BTC can buy you a car! Trading done in milli-BTC or micro-BTC
