One bitcoin one house is a real possibility and a touchable reality but the problem is when this will be real we would all be dead or at least most of us because maybe here there are really young people of age less than 20 years old. It will take several years until 1 bitcoin to reach 100.000 dollars as that is the minimum price to buy a house in a developed country. I agree with Zhang Dao whoever this guy is.
I don't know that is a bold statement to say because right now Bitcoin is price at 1440$ per Coin in which comparing to your goal is highly unlikely 100,000$ actually is a big amount and I don't think any usable currency can ever reach that kind of amount. I know everyone is thinking about Bitcoin being the currency of the future, but the future of Bitcoin itself is highly uncertain. With the government being an issue to it, even other competing Altcoins would be a threat to Bitcoin's growth in price. I would like to say is lets keep our goal realistically let us take advantage of what we have now.
If we look back not even a decade, a bitcoin could be bought for a dollar or so.
Who would have guessed that time that it would be worth a thousand times that much today?
I say if such a developement has already happened in the past, it proves that it is possible.
One bitcoin equals one house in a developed country in twenty years, I say why not.
