Government will NEVER be able to stop crypto. If they start regulating exchanges, then we shall create DECENTRALIZED exchanges. If they try to screw Bitcoin merchants over by sting operations, then we shall create a system which guarantees no FBI agents will ever be able to screw anyone over. If they try regulating the domains on which they run, then we shall create a dark-web network of said exchanges.
Like I said: They will NEVER be able to regulate this or take away our beautiful Blockchain. NEVER. We will make sure of it.
