Dude! You really do understand how the real life game is played. The only aspect of your story that is a little off, being fictional of course, is that the Federal Reserve notes and the Yuan of China are all made up out of thin air as well. The difference with cryptocurrencies is that they are made by average people and not governing authorities. With any currency early adopters and first users get to reap the benefits of having large amounts of that currency at their disposal before inflation kicks in. It makes those dollars that they hold even more valuable in the long run. As for the long-term plan, there will be a global cryptocurrency that the United Nations will see to and watch over. All these cryptocurrencies is as you said a Grassroots effort that is really being run behind the scenes by the the world central banks. On the economies of the world collapse and their respective monies collapse this new crypto-currency will be instituted because it'll be unforgeable and Incorruptible as far as counterfeit goes. No one will be able to buy or sell without the governing authorities knowing about it. Great story upvoted and resteemed.
