Cryptocurrencies will disinter-mediate every centralized value exchange network over time. The ledgers keeping track of dollars, pounds, euros, and pesos, will exist on cryptocurrency ledgers - aka blockchains. Since the underpinnings of cryptocurrency is decentralized, distributed, and open source ; A democratic selection of digital money, via the free market, is now taking place . And this new regime of digital money is growing.
However, in order for us to obtain ultimate freedom we may need to come to grips with a major idea. We are the internet. And the only country that matters in the future is the internet. That is to say, the connected network of people. The only money that makes sense in this future is a new democratic form of math-based money (duh, did you really think it'd be credit cards and gold coins?) so that fairness is actually provable and not relied on trust of corrupt humans.
With cryptocurrencies like Bitcoin and Monero we have the tools for cutting off the middle men who have rigged the rules of the game to extract as much benefit to themselves as possible. By getting rid of this oppression we regain our freedom, our dignity to transact, and our ability to have our work energy be stored as money energy without needing to trust a third party.
Cryptocurrency isn't just a buzz word. It is the last hope we have of monetary freedom. It is Technological Promethean Fire! The old financial systems of the past are the kindle.
