I have to admit I also find myself drawn to some of the claims these systems make. But following the 'if it sounds to good to be true, it usually is' mantra I have not (yet) been sucked into one of these scams.
Most affiliates with these scammy signal sites use somewhat the same pattern. They pretend to review systems and warn you of scams and then suggest the one-and-only legit service. Even comments would let you believe you just found the wholy grail. Looking further into the suggested service and you will find that this is also a scammy one.
This site and forum looks to be legit with a rather large community base. Here also recommended/trusted signal services. So that raises the question:
Do some of you use these services? AND make money using them? Thanks in advance.
