Governments cant kill drugs which have physical form for centuries.
So they won't be able to kill cryptos, but they sure can criminalize them. Stupid enough to be implemented by govts.
Same reasons with you here. People will always find ways to circumvent the law if it is beneficial to them like this cryptocurrency for example. Cryptcurrencies like bitcoin eliminate the boundaries in financial technology, wherein anywhere in the world you can send and receive and accept payments.
