In cryptocurrency we rely on prediction and in the process of the observation, there are some prediction become false while some are accurate. We can't neglect prediction in the cryptocurrency market.
I somehow agree to what you have said, this is a speculative market so predictions do have its part.
But I'd say that we don't fully rely on them as the market has its own factor and basis on how it shall move. While those predictions are no doubt moving the market and affects it.
