Suppose from today Indian government declares Bitcoin as illegal in India then any exchange of Bitcoin become illegal that means buying, selling, purchasing with Bitcoin and accepting Bitcoin will be illegal.But before taking any step towards banning Bitcoin. The Indian government will definitely consider the loss of user investment and organization. To recover the user investment Indian government will provide some ultimatum to Trading companies to return users investment and make an exit from the market.If any country is going to ban Bitcoin then this situation is likely to happen in most of the cases but the situation can be change depending on the government action.
