It looks like the Ethereum trust (ETHE) just came online on July 21st. It will be interesting to see where the price levels out (I had a chart to post but it doesn't appear that I can post that within the comments on 3speak). I have done some trading of the Bitcoin trust (GBTC) in my IRA account and with this new information will likely put in a limit order for ETHE as well in order to diversify.

It still feels like we are a long way off from seeing institutional investments in true Alt-coins. I don't personally consider ETH to be an Alt at this point.
