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. 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.
Yes you're right about many ico's using ethereum platform's but not to serve the people instead all they want to victimized investors.
That's why if your basis is just about the usage of the platform then that's a bullshit to tell that this will overcome bitcoin for that reason
