My expectations are very positive. In the year 2017 what most caught the attention in bitcoin was its price (this is my opinion). For 2018, I believe that we will have great news about the acceptance and confidence of the users, I do not believe that the price will fall, on the contrary, will rise, but not equal the last increases.
I also believe that Bitcoin is going to be a higher price in 2018, day by day Bitcoin is becoming one of the demandable currency and people are getting closer to this platform nowadays, when you see the demand of the cryptocurrency market then you can understand about the real situation of the Bitcoin. In my opinion, Bitcoin will be at least $50000 in the year of 2018.
Not only that but also, Etherium and Litecoin also will become a huge price in 2018 Because of its popularity.
