If you think that the use of the telegram signals might help you to become a better trader i guess no, you can use those signals to give you an insight into what coin to trade but being a trader does not, id recommend not being dependent with the signals of others, try to give a shot to learn basic understanding in trading so you can analyze in yourself when is the ideal to make an entry and you dont need to wait from the information from those telegram signals, not only in telegram but also another form of social media platforms. Ideally, learn gain knowledge from those others, adapt, perform and if you make a mistake learn from it, it's part of learning.
