Indian government (maybe other also) say that " to ban cryptocurrency we need global help" my question is : can bitcoin be banned if all government will agree to ban bitcoin
i am something less experience and has bad english so ignore
Government cannot ban bitcoins. If they were able to, then by now you would have been running here and there to the banks. The reason for which government cannot ban Bitcoins is that due to the decentralised nature of the coin. Due to this, no other person or organisation can know how many Bitcoins I am holding or have in my wallet. But yes they can ban or blocklist the exchanges for which we wont be able to cash out the Bitcoins through exchanges. But guess what! We have always P2P deals available in order to encounter this. Hope this helps you OP to understand the things better.
