By the end of this calendar year, Bitcoin will be trading around $ 40k to $50K. There will be a significant amount of volatility before Bitcoin actually hits those levels. It seems like, many of the investors, as well as cryptocurrency enthusiasts, are actually positive about Bitcoin in this very year. The problem is that with a significant fall already seen, most of the retail investors are not pumping money into Bitcoin. This is the reason why the movement is not that strong currently when it comes to Bitcoins.
I think bitcoin will not touch 40k- 50k $ if you look at ath 2017 it is very unreasonable that it will likely return to a price of $ 15000
Its a double top scenario folding up. We may be heading downwards in the short term.
