I think the main problem for crypto ICO is?.the most severe problem would be SCAM project, that doesn't just making all the investors to to leave and avoid any project with (ICO)and they want' us to hellp fro them.
Definitely this scam project creates a very bad impact on the investors. Most of them lose trust and avoid some good projects. People need a protection in ICO to avoid scammers if it done then assume it will become a big success.
I agree. the main thing is not to fall under regulation)))
