It's hurt ethereum that is for sure, but its necessary growing pains - provided we learn from this. In the short term this should have been a period of bullish growth with the news of mastercard and cisco joining the EEA - however the bad news undid alot of that good. I would not panic though, as an investor in the short term i am very bullish about bitcoin but in the long term I feel ethereum has a better long term vision in terms of scalability and the potential of smart contracts. Realise though that ethereum as a viable product is still essentially in an alpha state of readiness. Until scalability is dramatically improved (and I have no reason to doubt it will be) smart contracts are just too slow and too expensive to be attractive to the mass audience.
