Is this usefull statistic? I,m doubt.
Anyway we need to read WP, explore team that develop and promote project and etc. if we want to participate in ICO or investing.

I want to see statistic about percentes of ICO that create some real product and was profitable for investors.

Thank you for your comment. I think that such information can be useful for those who are just going to participate in ISO. Studying PR campaigns of similar projects can be quite useful information, in my opinion.
