Total waste of time and yes its risky as well because you are too dependent and for sure if you follow any trading signal, you might not want to analyze on your own anymore which put you on a bigger risk. This is not advisable and I don’t tray any trading signal group especially on telegram, if you want to be more productive in trading do your best to learn and trade on your own.
Yeah, they're a waste of time and as well as money. AFAIK, there have been fees just for someone to retain his space in any signal group. Some may say that it's totally free but at what cost? they're selling a service in return for getting commissions or paid membership for those signals.
Being resourceful an active reader of different news is better for you to get the scope of the current market.
That's what they do and outsource every time recently and then later, that's what they're going to send to you.
