I'm trying to understand why are so many people against bitcoin? is it the innovation that scares them? the feeling of staying behind? the fact that that money will go to the wrong hands?
I don't see any backlash from regular people. They're not against it they're just indifferent to it for many reasons such as they unaware of it, don't understand the concept and benefits, it's just some weird new stuff that they can do without, listen to sources that tell them that it's scam, don't want to risk or can't do it.
I think the only way to change their minds apart from educating them is to set an example.
If they see that you, a regular person like them, double or triple your investments without suffering loses and made your life better it'll generate interest for them to get a deeper understanding of it.
