All possibilities could happen. I'm optimistic bitcoin will hit $ 15k or more before 2018. Just look at the current rate of $ 13,188.30 (coin market cap right now) is already close to $ 15k. Go .. bitcoin to the moon. Wish I have alot.
That's too good in year 2017, there's actually no positive feedback we get from cryptos in 2018 and I hope even more updates will come now in 2019, that might also pump the price of cryptocurrency in the market.
Actually what bitcoin reached is far more from what Ops predictions since the value had hit almost $20,000 before 2018
But the sad part is what we struggled in the following year that i am praying not to hallen this 2019 though theres alot of speculative issues that this will continue untill 2020 arrived so for me,lets hang on and never give up guys,there alot of things to come for us in crypo world
