I could relate to those people that doesn't talk well.
To be honest, I am useless when we talk about promoting Bitcoin. I could talk to people about it when someone open something related to it. It is like I could push it there sometimes but we usually ends up with the scams that is happening until we just forget all about Bitcoin and cryptocurrencies and just talk about scams.
Really, getting people convinced in what they don't have interest in is more difficult than to convince them in what they have not heard about. Many people see the internet as a scam environment and this makes it difficult generally but the social media like Facebook helps people to read more about it. For instance, the Facebook bounties make some friends know about it.
