The market is quite bleak so I think in 2018 the price of bitcoin will not be able to reach the price as above. To be able to reach this price it needs more time in 2019.
It does not seems that even by year end the price of 40k can be reached. But we are seeing some good moment now and seems that 2017 could be repeated in coming 5 months. We are awaiting some boost to the demand which can take the price to 10k par.
