There are still some countries which bitcoin is not legalized that is making many of their citizens not to have any idea on digital currency in the country.
I think it's not a hindrance for someone who wants to know about anything, moreover if their country is against with bitcoin they are more likely to know and research about it due to curiosity that will strike their heads.
Many government are still seeing bitcoin as a scam currency which is not centralized in the world that is making some country not to allow such currency in their country because the currency is not control by the government in the country.
Nah, I don't think "scam" is the reason why some governments are not into bitcoin, it is just that a precaution for them not to take any hype from what is on the trend. Besides, people are free to use any kind of currency they want if their country isn't that strict.
Bitcoin is well legalized in my country where you can eat and pay with bitcoin in any restaurant in the community without any question of paying with Bitcoin which everyone are use to in the country. Every citizens in the country are use to bitcoin investment which many people have use it to grow their businesse in the country.
Here too, I noticed a massive changes after 2017's overhype on cryptocurrencies with bitcoin reaching $20K. I can even pay with bitcoin in here, like electricity bills, water bills, etc. I hope there'll be more of crypto concepts ahead of us.
