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.
Ethereum is gaining acceptance now because it is filled up with shitty tokens on its platform and even though I believe it has really come up with some development in this space, it has also been able to add to the craziness of this space somehow.
I do not know how Ethereum will be the future of cryptocurrencies though, but with the way things are going and with the smart contract usage, I am pretty sure somehow, Ethereum may actually end up being overtaken. Like someone rightly said, what you are seeing is just a beta test and I do not think Ethereum really have what it takes to compete in the long run except a huge development comes to the protocol.
