Prediction is the core of bitcoin market. Without prediction, entire market is bound to fail. We invest in bitcoins because we believe that the value of bitcoin will be high in future. That's one kind of prediction.
Also majority of the crypto trades are based on short term predictions. If people stop predicting/speculating bitcoin's price, the market movement will be halted and the growth will be stopped. Bitcoin is largely a speculative asset. Without prediction, nothing will be achieved.
This is true. Although, there are some forecasts that are considered to be false, which are primarily from the whales. I think people should not necessarily boycott their reliance on predictions and speculations. Rather, people should be vigilant regarding the news or speculations they are reading. Not everything we find in the internet is true and it is important to double check our knowledge before acting on it.
