I guess you need to still be cautious, like joining the group and seeing how it goes first, even if you want to try, don't immediately put a big amount, try it little by little until you're sure that they're trusted.
Anyway, it's still better if you don't really depend on that, but might use them for additional source of information or such.
If those people are really making out some profits then they wouldnt really be going into the public and trying to run up with some paid signals because they can eventually
make up some money with just simply making trades on their own without wasting up their effort on trying to handle out people.Its just really no sense at all.
There are lots of groups that do pop out even free ones which theres always a tendency that its always just a simple speculation that even yourself
could do such thing.So i dont see the worth.
