A lot of scams have caused the fear of theft among people and they are regarding bitcoin and its trading a scam. People seem to be reluctant towards investing in bitcoins. How do we ensure them that bitcoins are not scam but the people are. 
Well, we cannot certainly push people to believe on us because primarily, they might already have the trauma from the recent experiences with regards to investing in online investments that turned out to be scams so it is hard for them to believe that cryptocurrency is different beyond those since the system and the whole currency as well are being controlled or manipulated by anonymous beings. But with lots of patience and proving them that you are sincerely experiencing a good life with crypto, maybe their perceptions will change and they will start believing as well as investing with cryptocurrency.
