My questions is, are these signals true?
the signals may be true, but the main problem is that the guys sending the signals may be sending signals for games with low odds and in this way they may be getting the signals right but people will not be making profits, for example someone may be sending signals for games with odds of @1.10 and even if people won 9 times, it would be enough for you to lose two or three times to end up with big losses
