If you look at Gdax you will see that a lot of whales are getting out of the market selling 100+BTC.
The reason why the price follows the pattern below:
1)Drop
2)Rebound
3)Strong Drop
Is because the rebound is called bull trap, and this is to convince people that the correction is over and make them buy back, while in reality its a chance for whales to sell all of their coins to us.
Again, this is just a possibility.
