It was just a matter of time, banks and governments have wanted to destroy bitcoin from the very beginning and they realized very soon that despite all their power they are really bad at dealing with enemies that do not have a central base of operations so destroying bitcoin is impossible, so what to do? They switched tactics and they tried to scare people away by saying that bitcoin was only used by criminals and that has failed as well as institutional investors are finally coming to the market.
So what can they do? To create their own cryptocurrencies, claim that their coins are better than bitcoin with the help of the media and hope that they deceive most people this way, and in a way I think it is a good tactic as most people do not know enough about the economy to actually tell why bitcoin is better.
Fiat is used by criminals and for illegal purposes and many times these banks don't do anything about it.
