As of now, there are only 14 members in the group and I think if you have a good service this might have an interest in everyone who will find your group. It is good to hear that you are giving free tips to everyone but they need to understand that the crypto market is unpredictable and there are no accurate tools to predict on it.
How about if you also open a group with open conversation not just a channel group. But anyway, thank you for your effort and keep up the good work and I hope all you have been broadcast is accurate so that they will earn a profit. The important is, how to do stop-loss and how to broadcast buy/sell point.
