I think ethereum is gaining more acceptance among business and that is why we are seeing many icos using it to raise funds from the public.
But most of those ICOs doesn't really have a business to support. Its not about business but its more accepted with project because they can easily create their tokened form of distribution of dividends/shares or profit.
We should not undermined the significant of this in cryptocurrencies development because a particular coins must be adopted for a particular purposes and that is what I see with ethereum and fund raising.
People are becoming smart now and majority learned about these ICOs that its not worth anymore. With the emergence of scam ICOs, investors are becoming fewer and feared of getting involved with any of them because they can lose their money.
