Ok, so there is a new year coming up soon, but let's speculate of where Bitcoin will finish the year. So, I say the best way to do this is to put your high of the day & low of the day price for Bitcoin on December 31. Also, if you're a bull, then you can just put the high & if you're a bear, then you can just put the low. But just as an example, I will put both.
We will use UTC for the official end of 2017.
Here is my pick for December 31, 2017
High of the Day: $22,750
Low of the Day: $21,250
we only will say numbers but no one can give you near price because at 2017/11 we all thinking bitcoin will be 10,000$ at 2018/Jan.
my prediction for December 31, 2017 is 22,000$
