If it can buy one house today, it will be able to buy a mansion 5 years down the line. Wow, what a wonderful world it will be where nobody spends on anything because their magical Bitcoins will be worth more in future. What an amazing economy it will be. Nobody will work, everyone will just sit home and watch their Bitcoins go to moon and dream about what all they can purchase with their Bitcoins in future.
