But what about illiterate people who have no trust on digital currency? It is so tough to teach about digital currency. Besides, we have to teach them about the risk of investment also. If we able to teach them both pros and cons of Bitcoin, I think they will be able to adopt with it easily.
Illiterate people can be convinced with proper introduction, proper talk, and examples. People don't trust things that they don't know. But it is proven that once people understand what that thing can do and learned that is beneficial to them, they will either immediately trust or slowly open their mind to accepting facts.
Patience and a bit of perseverance and consistency, are needed in this kind of scenario. Introducing Bitcoin to illiterate will be a challenge but with proper planning and proper guidelines, I believe these people will be able to understand Bitcoin and will open their mind and hart into accepting it.
