Right now in some of the countries Bitcoin is been banned or restricted, when I think of it I do not blame the government why Bitcoin or cryptocurrencies is been restricted because they do not know the value or importance of Bitcoin. Some government officials have never done any transactions, I mean to buy or invest to Bitcoin or to use Bitcoin as a means to acquire goods and services.
Bitcoin will be more effective in the future, because presently people who are more into cryptocurrency are the younger ones (18-50 years in age).
They know the value and importance of Bitcoin. Despite the ban of Bitcoin in some countries, some individuals mostly the younger ones still have access to Bitcoin. I believe will be more effective in the future.
The government is not trying to regulate it just because they don't know the value or importance of using it, but rather they consider it as illegal and a threat to their country. Moreover, it is prone to illegal activities which are beyond their jurisdictions and cannot be easily tracked by them. Maybe in the future, more countries will consider BTC as a legal tender in their country or banned all related activities in crypto just like on what've been done by China. Well, no one knows, but the fact that more people have taken interest in crypto is a good indication of having a good future.
