looking at btc-e.. it seems
that as of 00:00 (time of graph) on
ETH/BTC tab the price of eth started to drop.
then as of 3:30 (time of graph) on
ETH/USD tab the price of eth started to drop.
also as of 3:30 (time of graph) on
BTC/USD tab the price of BTC started to RISE!
which is where other exchanges BTC/USD prices start to rise
it seems that something happened to hit ethereum's speculation negatively that happened 3 hours before people started buying back into bitcoin
(by the way i have noticed sometimes that btc-e has been the starting point that other exchanges follow(emphasis: sometimes))
