Of all the cryptocurrencies, ETH at least has a story about why it might have intrinsic value in the medium-term, beyond pure speculative passion: i.e. its use as a platform for smart contracts. But that potential only gets realised if more people use it for more significant purposes, rather than just for functionless ICOs or trivial games.
On the other hand, if this injection can help ETH grow this year, the backers of this fund should more than make their money back.
It's going to be an interesting year, I think. It's easy to shout bubble bubble bubble, and easy to shout buy buy buy. My hunch is that the reality will be more interesting than either.
