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.
no i do not think that banks are the worst enemies to bitcoin, i think that banks are bound to government and they cannot take any step without government permission. i am sure that when government will turn bitcoin as legal currency banks will also start accepting bitcoin and hope that then they will make their wallet system where one will safely deposit their money.
