There are many useless coins and many terrible ICOs but this is another example of throwing the baby out with the bathwater.
That does not mean that ALL are scams are useless.
ICO is a great tool.
We just have to learn how to use it
We easily can call 2017 as year of ICO. Among all those ICO that's are a lot of scam, mostly because of this area of business is still not regulated, but the process of regulating finelly began and I think it's good. Investors should to be protected from scammers.
I am agree with you that the idea of ICO is great, but we all need to learn to use if for good.
