What study is conducted that you've concluded about that? I don't think the crypto is even mostly adopted in the US, even here, few are believing about the worth of crypto, in that case, they didn't know more particulary what an ICO is.
ICO still has a lot of problems with SEC compliance and the only way for them to do that through use the 3rd party service but it's still impossible. I thought that will start to learn it but I can't even believe with this survey.
