You must be able to get some traction before ICO. If you can show vision, execution and hence traction you have many ways of promoting your product before ICO. So, I don't really think any real damage was done. ICO should be here to allow anyone to invest. Not a mean for anyone to raise money.

I think we are getting back to the roots now, which was good until the fucking IEOs started popping up. The worst ones are actually korean IEOs because the literally "airdrop" chicken to peoples home address trying to market shitty ICOs.
