I guess Bitcoin will cross $25K by the end of January 2018.
Hell, at this rate we may even see $25K before the end of 2017. But even if we don't, I'd say we will definitely be past the $25K mark in January 2018, because it looks like the price will continue to rise.
I agree, bitcoin makes us all shocked every seconds on its value. Last october we just say that it will reach $9000 but look on its price now its unbelievable right? No one thinks that it will reach it. I will not be shock if it reach that $25k before this year end or maybe january of 2018. Bitcoin always surprise us.
