Yes, I think so. Changing the world is not going to happen overnight, but I believe that crypto and especially block-chain technology are laying the foundation for the new world.
Cryptocurreny is a baby now. Since there are many ICos, the world is changing slowly. ICo projects with real projects sooner or later will change the world of economic ecosystem. Bobs repair by John Mc Cafee will change labour market in US and other countries. The growth of cryptoexchangers will replace old fashion fiat exchangers. George Soros have invested in cryptocurrency, What does it mean? every one knows that he is one of master traders. Now, he move some asset to cryptocurrency. This will effect fiat market and crypto market. Crypto market will grow. The traditional exchanger will be left and closed.
I really think so that crytocurrency will change the world.. because it will help many people specially poor people to become average people or become rich.. even without money by the use of cellphone you can join bounty campaignes and have your payment..
