I think that it would only encourage the usage of more cryptos and it's a great development from the stage when most of the countries earlier were in the idea of banning cryptos completely. This can't fully eliminate those ICOs that are not sincere with what they are working with but it can reduce the number of ICO generation as a whole.
And this is very important for the government to regulate or legalize the cyrptocurrency. This is actually the need of the day which is expanding in countries that are developed and rely on technological advancements.
Bitcoin has great potential to give rise to a new banking system if laws like fiscal and monetary policies are build around Bitcoin and then implementing those policies will enable the government to control the inflation and unemployment but I think it will still take a lot of time to get a system like this.
