I can say that nobody can say what value of bitcoin will be in 2018. There are a lot of false news saying that BTC will go up to 50K or even 80k. A lot of experts like financial advisor says that BTC is scary because of how it moves and it is really unpredictable and it has to take a lot of study on what or how will bitcoin move.

Well, if they say that it will go up to 50 thousand dollars then a lot of people will get rich instantly
