You need to get out more. The whole world isn't crypto traders moving from coin to coin. Many people who have barely heard of crypto at all (certainly have heard of little beyond Bitcoin) are starting to follow Eth/DAO now. That does't mean they will all invest, but it also doesn't mean they won't.

Coinbase is adding ETH to their exchange. It's not in the wallet, but it's only a click away. That's an easy onramp for 500 million (or more?) potential investors.
