I think the worst enemy is the bankers, crypto will be the end of banking, as there will be no need for them, thank God for that, The bankers are the biggest criminals in the world.
Maybe you mean banks? cause banks and banking has big difference. Bitcoin offers banking and more whereas you control your own money. Whereas banks is a third party intermediary thus saying crypto will be the end of banking is entirely wrong. I say cryptocurrencies revolutionize banking whereby these traditional banks are no longer relevant to conduct commerce.
