Interesting, first you say you are giving away free signals, a few hours later you are selling them. Doesn't look odd at all, but whatever.
Usually, all of those people who come to announce to provide free signals have the intention to start a premium paid signal service, once they hit a few successful signals. Usually, these people will give you 4 -5 signals per day, and even if one or two signals get hit, they will create so much hype and force you to join their premium service. Therefore I usually avoid these unknown signal groups.
