From the day you posted it till now market move up a bit than $160 in the last 3 days then dump a little in this day. It looks to me that would be going stable here between $150 and $160. But as what majority said, such movement was influenced by Bitcoin itself, well I agree as there are no significant news related to ETH alone on why did it move like that. So may be for now, as long as BTC pump rest assured that ETH or let's say several altcoins would do the same.
