Signal groups are risky and if you don't prepare your knowledge and have your analysis, totally rely on signals from any group will result in losses for you.

Signal group with joining fee is not a certificate that everyone in that group will get profit. Consider the signals they give members are good, the sooner you receive signals and take your orders, your higher odds you can get profit. In contrast, if you receive the signals later (much later) that other members in that group, and you don't care to make your analysis, you set up orders and join the party at high price when it is almost ending. You will get losses.

Signal groups are for pumps and dumps.
