So many new ICO, and they all have new idea and tech listed on their webpages,
and even the websites use the same template...
but so many new ICO, how to check if it's scam, or worth to invest...
There is no 100% sure way, but finding information, reading white pages, talking to developers, good ideas, having big sponsoring companies, having real product applications, etc.
The less information you can find, the greater the probability of fraud.
