I think Telegram channels can only help you, and can help you enhance your experience a little bit more, but when you depend on Telegram channels to do something, it's definitely bad for you, because then you're just as good. Can't learn.
Telegram channels can be good source of information for those who know what they are looking for. Depending on Telegram channels and making your investment decision 100% on the basis of Telegram channel's signals and analysis then you are putting yourself in high risk.
Always consider to check the projects by yourself. check their websites, audit details and everything which can be helpful for your due diligence. then make your investment decision.
That will reduce your risk a lot. if not 100%..
