Is there something big going on? I'm asking because if it's just a hype thing (like the Mike Hearn thing) this would be a good time to buy. Otherwise I don't know
It could be (to some degree) an effect of DAO crowdfunding. They're the most
successful campaign in the history with over $164m raised so far.
They only accept ETH, so I reckon there must have been lots of people who dumped BTC for ETH in order to buy in to DAO. ETH price going up seems to confirm this.
Other factor could be disagreements within Core devs/Blockstream team (G. Maxwell calling Adam Back/Luke Jr dipshits etc).
