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.
To me, i believe now in bitcoin price prediction because believing in prediction we gain more profit but people need to believe those type of prediction about the bitcoin price which are establish in official websites and also follow the high profile expert prediction. Moreover, i believe in bitcoin that one day we see its price 15k to 18k usd again.
