Who's banning crypto? All countries are implementing it and making relevant laws.
I believe that when government ban bitcoin they tend not to fully inform the public about bitcoin to prevent them from having curious about it. But when it comes to informing people about bitcoin it is better that the public is aware about the existence of cryptocurrency and how it will change the monetary world.
Well if a government tries to ban cryptocurrencies, it means that cryptocurrencies are popular already and people are investing in it, because if it wasn't a threat they wouldn't try to ban it. In order to prevent this from happening, increasing public awareness is key, so that people recognize bitcoin as a legitimate investment method and they can speak up if the government tries to ban it.
