As more city based cryptocurrencies arise, the less power the Federal Reserve will have. Anyone who has researched the Fed, financial terrorism and who can see the obvious fact that the fed funds the military industrial complex, will realize how huge this vision of the future is. This is and will be a keystone development for the ongoing decentrolution.
Many of these city coins will be Ethereum based, simply because Ethereum will continue to be the go-to interface for the technology, as the current and future leader in the industry. Those programmers who prefer the C languages and .net framework will work with Ethereum through Stratis.
Can you see how huge this prediction is at so many levels? Not only will Ethereum explode, but the cryptosphere system will also be so massive that we will all take it for granted as we do paper cash today. Thousands of city coins will be the norm, and crypto trading will be even more awesome than it is today. All of this will happen and deleverage the power that any federal reserve bank has on its populace. This is the decentrolution.
