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 $1000 in June 2017 (+/- 2 months or so) if it continues at this pace.
The price of the bitcoin is slowly increasing and decreasing every week and it's not really stable when it comes on the martket too in your prediction or as in OP bitcoin will not truly sure that it will increase or hit into 1000$ in the year of june 2017 but we do not really know every things happen for a reason.
