There are many people who still don't know about bitcoin or other cryptocurrencies. I don't know about others I am talking about my country and about my society. Whenever I ask from people about or talk about the Bitcoin. They ask what is this?
How much there is who face this problem?
Mostly of those people were the ones who are not using the internet but it can be for those who were not interested too. In my place not all of them knows bitcoins and how it is being used because they had low to no chance of having it known due to poverty or such social tier were a big obstacle on having knowledge on bitcoins making them uninterested in the process.
