You have a point, for beginners who always follow the predictions of others, it is better not to enter the crypto industry because everyone should know predictions are not always right.
Only an idiot will follow the predictions of other people. Real investors who have a little bit of brain still intact would do their own research before putting their money in. They would form them own opinions, good or bad before buying anything.
In my opinion cryptocurrency has a greater risk than other assets, losses and panic are not always about whales or manipulation, losses in my opinion mostly occur because investors and holders do not have competency for that, they easily panic, too easily affected by FUD and FOMO.
Exactly the reason why people should take their investments at their own risk and not rely on other. Being reliant on others lead to the panic when the prices drop. If that same person was genuinely interested in the future of the project they would look into its pros and cons and then only take their step. They would not get affected by FUD or get FOMOed.
