Undoubtedly, the cryptographic world came to revolutionize the world financial market and to direct it towards a more honest and less corrupt economy. Unfortunately, as you have pointed out, there are already governments and businessmen who have seen a way to get a good slice of this pie. A notorious case is that of the Venezuelan government, which has launched its own crypto-currency. When I read this kind of article, I realize that some countries are still in diapers. For example, in Venezuela the value of cash equals gold. Everyone is looking for cash. The payment platforms are generally down and there is no card issue due to lack of plastic. If you don't have cash, you don't eat. In this country we are in the 20th century. Sad :(
