Since the low in January 2015, the price of Bitcoin has been increasing at a very consistent rate of about 6% per month. As shown on the graph below, the price should hit $1000 in June 2017 (+/- 2 months or so) if it continues at this pace.

I quite believe bitcoin could reach 1000USD. Today the price of bitcoin is 750USD. 250USD increase is very possible to occur during the next two months. because bitcoin prices can increase and decrease very quickly.
That's true, but for the price of bitcoin to reach up to $1,000 in June 2017 is quite too long because the price now for this fourth quarter of the year which is still not ending the price now is 3/4 for that aim price. My prediction that the price of bitcoin will reach $1,000 maybe by the end of December or January and it will be $1,100-$1,200 in June 2017.
Many factors affected bitcoin price to keep increasing right now, financial and economy crash, inflation make people choose to invest in bitcoin as it is decentralized digital currency that remain out of central bank system and not affected, make demand of bitcoin constantly increasing and now reach $740. Op right about 6% increased and the price could reach $1000 in June 2017 but the price in few last month has rapidly ascension so bitcoin may achieve $1000 by the end of the year.
