Will it hit 20K $ by end of 2017
I do not think bitcoin can hit 20k before 2018 , 15k possible But beware of a sudden dump May happen at any moment
There is possibility to hit 20k because bitcoin has grown so high and at this time bitcoin has ability to rise high within no time and all that happened just a week ago this was a trailer to the future rise of prices and bitcoin has attracted a lot of people in past and this trend will be continued in future so everything is possible now and maybe bitcoin will go above 20k till the end of 2k17 because who knows whats coming.
