Will it hit 20K $ by end of 2017
There is a possibility that it might hit, but also, there is a possibility it won't and for me, I will go with the possibility of it won't. There are a lot of planned forks this month and I think it will be affecting the price pump of bitcoin. We don't know what might happen, and no matter what did, I will be still holding bitcoin, don't have other reasons to sell them for now.
Forks are getting less and less important the more there are. Bitcoin Cash was a big deal because it was the first fork. Bitcoin Gold was not a big deal but still managed to get a value of what Bitcoin Cash used to be at. Bitcoin Diamond...who even heard of that haha, I saw mention of it in one article after the fork had already happened. I don't even know what further forks you are talking about this month, and each of them will have less and less impact.
