pipe dream. other crypto currencies would pop up, which would bring down BTC value.
blockchain confirmations take too long for BTC to be ubiquitous.
A lot of you underestimate the size of the global economy. There are hundreds of trillions of dollars which can flow into Bitcoin or the others like Bitshares, Mastercoin or Colored Coin.
1 million dollars is not as big of a deal as you all seem to think. I think $500,000 is realistic and even $100,000, but 1 million is also realistic and its just a matter of how long it will take to reach it.
or maybe you tend to believe the things you want to be true.
if BTC explodes and becomes ubiquitous, i am certain there will be other cryptocurrencies in the market.. and that would dilute the value of BTC down a bit. there are still issues with BTC that we don't know will be panned out.
hypothetically if BTC were 1 million dollars, that would be a major shift in the way the world works.
