To my knowledge people have talked much about bitcoin bane and it's rejected from the world but still they are not successful and it won't be true even we will not see that time when bitcoin will reject from the world and it is not controllable so people can use it every where in the world with out any further force and people use it for their good usage now.
For me, Bitcoin is not deserved to be banned without trying to it. Some basis to reject or banned bitcoin is because it can use to in some illgeal activities which is very wrong because it can cause to reject cryptocurremcyto avoid this kind of things. Hopefully, this kind of reason will gone in the future and many people are embrace cryptocurrency to have a good profit.
