In 2030, USD won't be the measure of value anymore. But if there is a hyperinflation, then yes BTC can be worth $100,000 each or even more. It is very possible. But you should measure your BTC in 2016 purchasing value of the dollar, instead of the dollar.
Could never agree this. However high the inflation might be USD continues to be the measure of bitcoin even after several years from now. No other currency is strong as dollar right now.
The US dollar has ruled the roost for over 200 years now. It is time for a change.
May not be bitcoin, but some other currency will take over soon.
