There's plenty of misinformation and scepticism about crypto, including amongst some people who are technically literate. I wonder how many of those who used to invest got bitten by scams or just lost money. They may regret it if they sold BTC early on. I never had any so I'm not bothered.
The media tend to just report the scandals. I've not seen much in general media that actually recommends investing in it. I think it can be part of your investments that may pay off nicely, but usual warnings apply about investing what you can afford to lose.
Most surveys I've seen suggest 50-50 up and down.
Not sure about scams. There is one org that surveys regularly I'll dig it out and drop the link in another comment!
The BBC is a great case study for only reporting negstive news.
Once you get below btc it tails off quick!
