My question is how we can turn their perspective into positive? I have good motive on that because I also want them to have a better lives by understanding how it works and also how we can chance their way of living by using it.
It's either we educate them, or they will just let themselves know what is the truth.
Educating them might change their perspective towards Bitcoin, but not for those who are close-minded people who only know that Bitcoin is a negative thing. For them, what they only know is that Bitcoin is a bad thing because it has been used for some criminal activities, and some lose money investing into it.
On the other hand, there will be a time where they will just realize that what they know isn't the reality. What they know is the complete opposite. What they think about Bitcoin is completely wrong. In short, there's nothing we can do about it, but there will be a time where they will realize that they all wrong about their perspective towards Bitcoin. We just let them know what is the truth about Bitcoin.
