So did ETHBTC get tired of waiting? It seems that this influx of buyers was triggered due to the airdrop of OmiseGo. You get 5% OMG for the amount of Ethereum you have in your wallet. As to when the snapshot will be taken, it's still TBA.
The current price could be at a potential bottom reversal and hit the supply zone before moving up.
Reason for price change is because of HP (Hewlett Packard) joining the Ethereum alliance.
