The world is going to adopt crypto-currencies.

Why? Because transparency is important.
The people that do bad things want it all hidden.
Yes, the FED has stopped QE... that's what they say, but all indicators are that they haven't. No transparency.

Early adopters are always rewarded.
As long as it is an evolution.

As opposed to a new thing in a dying market.
Such as self driving cars.
So many talk about self driving cars as the future, but really, the only people that want self driving cars are those who are stuck in traffic getting to work. And the solution to this is actually reconstructing the cities to allow for walking and bicycles.
People are pushing self diving cars as the future, while reality is abandoning the car as a necessity.
