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.
Effectiveness of Bitcoin depends on how viral Bitcoin go in the entire world. Different countries have their mode of exchange and many countries have plan of accepting bitcoin as mode of exchange and also some institutions are also wiling to make bitcon their main currency for payments of bills and others. So Bitcoin will surely be effective in the future.
