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.
This is all about the government why there are still a lot of countries that do not accept bitcoin and the only reason why they will not accept bitcoin is because of being decentralized and there is no way for them to put a tax on it which makes them feel more restricting cryptocurrency. It's all about the leadership and the mindset of the leader, if they cant see the benefits of accepting cryptocurrency then for sure everything will be fine.
Why future? It's already an effective financial tool in the present so I don't exactly think that it's going to be any different in the future. For me, the only thing that will change in the future is that there will be more people that's going to use bitcoin and the prices are definitely much higher than the last time.
You are questioning the future but you are also saying that price will definitely much higher if in the future we will have more people who will explore cryptocurrency.
