Goverment has a responsibility for that i think it they implement that can harm the growth of crypto we all know that banks are control by the goverment (central bank)
They are many possible speculation that they can manipulate the price of bitcoin. Because in thier part its alarming to them.
Not sure if banks are controlled by government or government is controlled by banks

Either way, I don't think that cryptos are alarming to banks or governments at all. If anything it gives them even greater leverage than FIAT money to control and regulate people.
