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
parable of the government and central bank trying to ban cryptocurrency, especially bitcoin.

source >>> google
the government may be able to intervene in cryptocurrency exchange platforms, and centralized altcoins but intervening in bitcoin is an impossibility. already millions of people who love bitcoin, if you want to turn off bitcoin then the government must restart millions of people's minds

In a simple image the reality is well explained. It isn't an easy think as the governments think. Maybe in the early days if they have planned to stop its usage, the governments might've got an opportunity. Now scenario is different and people are well aware of the need and they keep on making loopholes even if something is done outright to stop its usage.
