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.
No one can really predict the possible price of bitcoin and other cryptocurrencies in the future because it is unpredictable and always had an unstable price because of volatility. Many crypto analysts are trying to figure out when will the next bullrun happen but they failed to predict it accurately. So it might be better to monitor the market and study the price movement of the coins instead of relying on predictions.
It depends on the prediction itself, most predictions about it price of bitcoin are not going to come true and should not be taken seriously, but the predictions about what kind of future bitcoin will create are more important in my opinion and are closer to the reality, after all if someone predicted that bitcoin is going to be adopted globally and used all over the world I think that prediction is very accurate because there is almost no scenario in which bitcoin does not become an important currency in the world.
