I can't really recommend any group for you because am not always in support of copy trade or trading signals, since I don't really use it so I don't have much idea about it. But am sure when you get to Telegram you will see tons of those groups their, just that most of them are fake, they just want to take your money, so I won't recommend you to subscribe for any of them. But I know of a exchange that supports copy trade which is BYBIT exchange, actually have not used their copy trading futures before, some I can't say how it works, but you can just give it a trial. But avoid Telegram groups because most of them just want to scam you.
