And maybe anti crypto should read this because this is the first argument that they are going to throw at you when you have a good discussions/debates with them. At least in my case, this is their main argument when I got the chance to talk to people here about crypto, specially bitcoin.
I'd give up on that if I were you. Just continue loving and adopting Bitcoin, or doing whatever, there's almost no sense in arguing with FUDsters and the like. If you were to introduce BTC to a newbie, then maybe use the story, but for haters? Nah. We all just have to accept the fact that when there are lovers of something, there'd also be someone who'd just step up and hate it straight down without an ounce of research done about it.
Has anyone actually done research on this topic and can prove it?
If its stats, then the link provided by op should be more than enough. Research about this would basically concentrate on past events anyway.
