It seems to be some GIANT investors manipulating the bitcoin market.
Any ideas??

Actually this seems to be triggered by buzz about possible hard fork in near future. ETH and DASH are in high demand because they are second and third crypto by marketcap and right now all fear about possible price dump after hard fork so they are hedging against it by investing in other alts.
Yes. Its the hard fork dilemma that is causing this price fluctuations. So its really hard to predict the price right now. Next thing you know we are below $1000. I initially thought that there are entities behind the bitcoin ecosystem that is manilpulating the price, but now I hight doubt that. It's been the BU vs Core and the politics behind it that is causing a massive dump from different investors. So all we can do is hold to our bitcoins and see what the future will bring. But I hope we are still in the right direction whether hard fork is implemented, and $2000 price at the end is possible still.
