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.
Some country’s opinion is Bitcoin is illegal, this is a Virtual currency, nobody can touch it, also nobody can tracking their transaction and for this reason people will abuse it in many anti-social activities. So some country Banned Cryptocurrency, but it is correct that they haven’t any good idea about Bitcoin or Crypto-currency.
It's a normal thing that happens when there is a change in the times, there will always be pros and cons, although later they will also be considered, because we know we can't resist the development of the times in any way, but indeed this requires a long process to be relevant to the conditions at that time.
