I do believe it can be possible because of the rising Bitcoin, era and its popularity, added by the fact that as time passes by, many potential investors as well as consumers and users are continuoulsy engaging into Bitcoin, there is a large possibility that the prediction of Bitcoin getting into $50,000 by the end of 2018 will be true. But still, we can never tell it to be true nowadays because there is still a lot of possible happenings and changes that may affect this expected breakthrough because as we can observe, we are yet too far from that expected amount so there might be a great happening that may cause Bitcoin to rise up its price before the year 2018 ends
