Discuss with old statistics isn't best way to see the future. Yes, it's rate was increasing about 6% per month but also it can decrease. Your opinion is good result of discuss but I think bitcoin's price won't be so high in june 2017. I think it's price will be 700-800$ max, not higher but maybe lower. Bitcoin's price is more stable now and I think it won't increase greatly.
+1 for you , it won't happen in short time to achieve $1000 in 2017 maybe more longer but we're optimistic bitcoin would be reached this price in the future. We're in the stable price of bitcoin (I hope so) and it will be a long journey for bitcoin to increase the price (but anything is possible in the internet)
