Crypto currency itself will not change the world but blockchain techonology can bring more stability and trust into our world,but nothing revolutionary will happen
Why not? Crypto have some unique features for currency. And blockchain has unique features, you are right. And revolutionary is idea about emission and trust not as currency or technology. I think crypto change world already. And further we will see aftermath in the different cases.
I think it's clear that Crypto will become a future technology where all transactions will be easier and more practical in just a few seconds. and of course its scope is wider, because it is not bound by any country.
