Seeing the number of scam ICO I don't think it is helping the industry at any point (other than giving a bad reputation).
Here's the problem with bringing up scam ICO's all the time...for the most part anyone with half a brain can tell when an ICO is a scam, but people still fall for them. It's really no different than scams in real estate. You always see people selling "land" that turns out to be swamps or other scams in real estate but no one thinks that the real estate industry has a bad reputation.
Yes, scam ICO's do exist but scams exist with any investment industry. It's up to the investor to be diligent and do their research before they put their money into something.
