Not totally full of shit but there are people who are really that confident with their analysis thats why they do really make out some claims on something they are really very sure to happen.
Who are those? We even know that analysts are either correct or wrong. There has been time analysts would say the market will be bullish but bearish will be the market. Even analysts will always give conditions which will be confusing as they will say if the price decreases to a point, it will be bearish, but if it increases to a point, it will be bullish.
I can only speculate that those who are confident of their predictions are heavily on the bitcoin side, meaning they have invested so much money that they want to predict it that it will be bullish so that their money will continue to grow. But when the market shows bearish, then continue to preach otherwise, for obvious reasons that they have some narrative behind, so they are biased on their predictions and analyst.
