I doubt whatever you are saying. Right now obviously there is no way you can say that cryptocurrency is actually affecting the overall economy. A fraction of even the whole of the global market cap combined is nothing in front of the fiat and stock's economy that is going on. But yes talking about the future, right now until legalization kicks in anything can't be said, but even after legalizing it, chances are it will just become an investment tool, even in that case it won't become a major part of the economy, it'll even be far behind the commodities economy. Surely it's an issue the world has eyes on but surely not a thing that can impact global economy so quickly.
