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.
They declare it as illegal since they don't know how its technology works also they maybe see it as a threat due to many scams happen using bitcoin nor in their financial ecosystem but time will comes that many country will adopt it as bitcoin is continuously booming around, For sure the trillion dollar cap of cryptocurrency will make those govern bodies that its worth to adopt changes due to possible millions of taxes they can get from this industry.
