do you think many of them are starting to dabble in Ethereum also?

Yes I believe that to be the case. The way I see it and the way I think they see it is, there is bitcoin as a store of value and there is Ethereum as a crypto sandbox where everything is being built, and then there is everything else well behind those two. I have heard Mike Novogratz mention his Galaxy fund getting into Ethereum as well as some of his buddies. I don't think there is nearly as much institutional money as there is in BTC though, and it will take time for it to catch up, but eventually it will probably be an institution favorite like bitcoin is now.
