I think education is the best way to change people's opinions about Bitcoin and blockchain technology. With education, people can learn about the technology, its use cases and the potential benefits it can bring. You can start by creating a website or blog that explains the basics of Bitcoin and blockchain technology and how it can be used in a positive way. You can also create informational videos, tutotrials and other materials that will help people understand the technology better.
Nowadays, you can find websites, videos, and blogs about bitcoin a lot, it is not a new and effective solution. I agree that education is the only way to help people understand bitcoin, but for education to be effective, it needs to be included in educational programs in schools. It's the best way to help people get educated about bitcoin.
