I'm thinking blue line and a disapointing 2017 myself, or perhaps pink
I agree with the blue!
But maybe not a so long one, maybe 2017 won't be a whole disapointment. I see the price dropping back to 650/700 but not to 500 as the blue suggests. And especially not for so long even though I believe we'll have to face this price for some times.
The others solution aren't realistic. Current situation says that price can't support a full upper trend right now but it's still the global trend so expecting for a strong decrease is stupid. And orange isn't something I'd like to see happening :3
And the funny thing is when you look at the poll: guess who voted green? xD
