Oh, you are so pessimistic about this matter.
I thought that it is more easy, you pay for signals and sellers are earning from subscription, so they should deliver the best signals to attract investors or?
He's actually right. Nothing comes off easy. You have to work hard for it. There are so many online resources now like YouTube and other trade analysis platforms. The best you could do is try to do some digging while also trying to practice trading with some small funds, with time you will gain experience. This helps you to avoid getting scammed as there are so many scammers out there waiting to trick you in every way possible.
