The Prose of Cryptocurrency?

crypto currency aims to eliminate the need for institutions and banks to be involved in the process of your money. But on the fllop side, if you're exchanging coin to something else, there's still going to be exchange rate fees. The idea is that eventually people will hold on to bit coin the same way they hold on to gold as esment. And then in terms of some of the cons this is the biggest con for me, is that it relies on people believing in it.
