Maybe in future we might ask money but now you can enjoy our signals for Free.
I certainly think you'll ask for money in the future/after a few days because this is why you inviting people to your free group.
I would like to ask a question here. If you are such an expert trader and you can make money from the market, then why do you need to sell signals?
Anyway, if anyone want to join this group? Or have already joined. Then remember that most of the signal groups are fake and because of their bad accuracy you'll lose your money.
99% of crypto signal providers are fake, and beginning traders should be especially wary. Crypto trading signals groups are targeting you in particular because of your limited experience, hoping that you'll trade your hard-earned coin for an easy or certain pathway to trading
