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.
Show them. Don't tell them. There's too much talk about bitcoin. Too much trying to convince and persuade the naysayers. The public ( not everyone) has their different opinions and perceptions about Bitcoin based on their own experiences. Start with one person in the public and not like 5 people.
So, like I said show them don't tell them. Show them the practical application and real life use cases of Bitcoin in money transfer, cross border payments, identity management, real estate, decentralized finance, in retail, in smart contracts,Send them video and audio links, send them books on Bitcoin and cryptocurrency, invite them to Bitcoin and cryptocurrency conferences where they will meet and network with professionals doing amazing work in the industry. If after you have done this and their perspective doesn't change then let them be.
