Listen to "publicly" advices will hurt your trading because everyone has his way to think, concept of profits, how to make  profits and thus earns $ 100 is a win for you and a loss of other especially if tax are taking into account.

If it is better to avoid listening to other advice, then what about unknown people, you do not know them and they may be paid to promote a particular project. So avoid those channels at all and stop recommending them for your friends.
