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
Yes I agree with you. Because 20,000$ is very high value. I don't think in a month the price will move from 11.5k to 20k.It will happen only if the miracle is happened. 8500$ in a single month ,I won't think this will occur. Bitcoin price will reach the maximum raise of 15,000$.Even you can inverse your money in bitcoin now,obviously you will get more profit it.
