The answer to your question is in your post, like if people are consuming bad opinions from whatever source and taking BTC as wrong then all we can do is show them the right path. It does not matter how you will do it like by talking to them directly or by increasing the good opinion to be consumed by them so they could think of it as good.

Overall, this factor has some significant importance but to some extent, people need basic knowledge and confidence in themselves so that they do not depend on the research or opinions of others. One thing that they assume about BTC as being bad is, regulatory restrictions and less educational content like if at the start, due to no access to the right knowledge I left BTC then again I step feet into crypto and found this forum and after some time I started to understand basics of crypto after which, I totally understand how things work.

I have seen most of the people who try to ask their friends or relatives involved in BTC about its origin and purpose, those who taught them like from an advanced level or try to teach them very hard idk why. But this confuses them and they tend to leave it. That's why we should teach those who find it hard to learn about BTC and blockchain.
