from the beginning I never believed in such predictions. early in the year many predicted that the price of bitcoin would be very high in 2018, but now they are all silent.
The predictions are only taken from their desires. They wish they had a lot of profit so they expect prices to rise, so most of the positive predictions about the market in 2018. And the real situation goes against those predictions. I do not believe that bitcoin prices in 2018 could go up, only to go down and go down in the long time
