Everything in my opinion can happen in trading, predictions is a source of getting close to the problem in trading but didn't have a 100% accuracy in every and each prediction.
Predictions dont get close to the problem. They just predict a price to buy or sell. It has nothing to do with problems and their solutions.
Also a 100% accurate prediction is not a prediction, it is called a fact. Hence they dont exist in a speculative market. You have to assume every prediction to be 50-50 before taking it.
So, always try to be realistic and don't depends mostly on these predictions, and another thing always learn by yourself and be experienced always.
If traders were realisitic then the craze for altcoins and then their successors and the current NFT, DeFi craze would never exist. You just have to deal with the fact that the co-traders are all crazy about unrealistic gains.
But to be safe, one should keep bitcoin as their biggest investment in cryptocurrency. If you got money to spare, go for fiat markets, dont waste it on hyped hyped crypto assets which have no future.
