In my opinion i think that bitcoin will hit 25000 usd in the middle of the year of 2018.The way btc is now increasing it can easily surface 25000 usd within few months.
If you purely look at how much growth we have experienced this year, and just straightly assume it will stretch out till next year, then the $25,000 level doesn't seem like a major obstacle to overcome. However, we have to understand that the growth we have gone through this year is abnormally high, and will likely not be experienced in a similar fashion again in the forthcoming years. It's beyond insane that Bitcoin goes up like 900% in a matter of eleven months. These level of growth rates are usually only something happening with altcoins due to their insanely thin markets.
