The case of Bitcoin is a similar one with that of football where everyone would come say what they believe and also make their own predictions sometimes their prediction may turn out to be true why at sometimes it will be 100% wrong the same to Bitcoin everyone must definitely come out to predict what they observe but we mustn't take everything too seriously and also try to access risks because fear can make you loose what you can achieve because of one man's prediction
Personally I wouldn’t correlate it with football speculations and predictions and the reason why I said that was because football and sport predictions never ever have better strategies to analyze their game. But in bitcoin and cryptocurrency at large you have many analysis options like the Technical analysis, fundamental analysis and even sentimental analysis. All this three will give you some insights or perspective as to the direction where you think the market will move to next.
But this is not what this self proclaimed analyst do rather they simply FUD with price than say predictions. Yes this doesn’t mean the Market can not come low as their predictions but their is not true analysis behind the prediction which is baseless
