I think it's a bad idea to use trading signal and bots because it might hindered the learning process of a beginner. Maybe as a reference trading signal can be use. Remember that a trader should develop his/her own system that consistently made him/her money.
It also depends on the type of trader you want to be. If you want to be a high variance and a risk-taking trader then maybe these groups can help you because if even 1 out of 5 times they predict something good you can easily recover the loss in the other 4 trades and signals they gave.
If you want to be a stable and solid trader then all these groups, signals and tips will never help you. Neither of the two is better than the other but I would rather prefer solid and recurring profits than having high but inconsistent profit.
