Trading signal groups are scam so don't get deceived, almost everyone knows how to buy on an exchange because that is how they used to have their first cryptocurrency or atleast it can be learnt using simple Google search.
If someone wants to be a regular trader then they need to have skills on analysing the charts and back-up plans if they lose their capital.
Signal groups are both a scam, and not a scam at the same time. They are a scam by logic because they have done nothing that would provide proof of profit because they are dealing with "signals" which is just basically indicators hitting right points, and that is not a guaranteed way to make money, it doesn't mean that you will profit, which is why there is nothing we can do with signals that guarantees profit in the end.
There is a situation where we will end up with people who mean "good", they could be good people who think they are doing the right thing, which is why I say they may not be scammers, but the reality is that if they are not doing anything that scams others, but doing something that promotes a chance of profit because they believe in it but still fail to provide profit, they are just unsuccessful people and that's it.
