in my opinion it's wrong. we must get information from all sources including market predictions or predictions from coin trading experts. so we can get more knowledge if we will invest or start trading coins. we will also get more up-to-date information if we follow market predictions.
Without predictions such as walking without direction, therefore the predictions of experts are used as a reference for making decisions in bitcoin trading or investment. But, the predictions of experts can be ignored if our calculations are different. Because their predictions can also be wrong.
