No, bitcoin can be tried to ban, but technically it's impossible to organize.
It is not possible to control, and therefore punish for using it.
Hence the ban is absolutely meaningless.
Although Bitcoin is not possible to control by government and bank central but the government of all countries can prohibit their people use bitcoin, using bitcoin is considered a criminal and you will be arrested then everybody will stop using bitcoin when bitcoin will be died. I see some countries are performing this like Bangladesh, Nepal, Morocco
If any country ban bitcoin so I think he is doing mistake because bitcoin can play a very good role in economy of many countries as now it is playing in my country it also reduced unemployment in my country so I think bitcoin must not be ban because its here to help us bitcoin is also now accepted to many countries and some banks have already made bitcoin legal which is a very good thing and Im sure that in next year more countries will join bitcoin.
