1k mid 2017 is very possible. In fact, I think we might hit 1.5k by the next halving.
Honestly we would be in the 1k+ area by now or by November if the Bitfinex hack didn't happen.
Next halving is in 2020 my friend.
$1500 at that time would be a bit disappointing imo.
From first official listing ($0.07) to first halving we gained over 17100%!! From there to second halving we gained over 5200%!!!
And from here($635 on halving day) to next halving in 2020 and a price of $1500 would mean we only gained 236% in 4 years.
I'm hoping for a bit more to be honest!
