Well, I think that public opinion on the cryptic world has already changed. People are currently moving towards crypto-currency. Because it has the potential to make people profitable through investment.
We need to guide public properly about bitcoin and teach them how bitcoin work especially women's because the percentage of women who use bitcoin is very less.
We can't control the life and the mindset of the public view right now but we can always find a way for us to trust them, a lot of scammers out there trying to scam and it destroys the reputation of the cryptocurrency especially the bitcoin, but in time the mindset of the people will eventually change as the time passed by.
