There are many stories and threads here that people are taking advice from different signalling group about different coin(s). Anyone following such groups has lost his money and time but the worst part of this is that he didnt learn anything about trading in the long run.
No free lunch. If they give you free lunch, is it realistic?
They can give you free lunch with some signals to attract you and to convince you that their signals are free and good. When you join them more deeply, you lose because they will go ahead of you by buying first with cheaper prices. Then they give you signals to buying up the price for them. Your buying can trigger trading bots to work lifting up the price.
If you can join before break out, you can get profit but if you join after a break out, a later you join a bigger risk with loss you will possibly get.
You need to spend time and effort in order to learn any type of trading. You wont excel until you learn to trade yourself and learning is putting your effort, spending time, bearing loss etc. There is no easy money in this world, everything comes with effort.
Learning is never wasting and you have to learn about investment, trading. Practicing both of them and see what can work best with you, trading or investment, then choosing one to use with your capital.
