Very true. You are your own expert, nobody is expert in cryptocurrency because it is unpredicted. We are all trying to understand cryptocurrency, from the experience we gain from cryptocurrency can make us to be our own expert. Nobody is an expert to your investment or trading. That's why when people predict market we shouldn't always feel the predictions will always come to past because bitcoin is unpredictable and no one can exactly predict what will happen in the market.
In cryptocurrency no one can identify about market because their is a possibility that market can change in matter of seconds so if someone predicts then it will not 100% accurate as accuracy of prediction does not exists in crypto market.
Everyone is not a master and everyone is not sharing their own thoughts even there are some influencers who copy the details of other influencers and show that they know each and everything but it is a fact that nothing can be known by anyone about crypto.
If someone make prediction according to the past history then most of the time it become true because bitcoin is repeating its cycle of four years but we cannot say that all the time the prediction become true and we should not blame influencers if we are unaware of the fact.
