I believe that we should never trust 100% in any prediction about it, even if that person is presented as the greatest expert or master on the subject, because we must always keep in mind that at the beginning of 2017, when the price of bitcoin was just in $1,000, none of those alleged "gurus" was able to predict that the price of bitcoin would reach $20k some months later. And besides, neither was able to predict the tremendous collapse that the market would suffer next.
If those relevant historical events went completely unnoticed by the "experts", I think none of them has real bases to present themselves these days announcing that bitcoin will reach this or that price by the end of the year.
Most of the "experts" are paid and always make predictions that favor them, so of course any prediction is useless without an in-depth analysis of who, when, and why made it.
The thing is maybe you believe to those who are good on flowery words or somewhat those who are good at marketing. Predictions should be made with credibility, with sources that are reliable. It must be objective in order to avoid fallacy. Bitcoin has always been predicted because of the volatility of the market but still it is the cycle we can always expect the downfall and the rising of bitcoin.
