99.9999% of the people claiming to give trading signals in return for paid subscriptions are scammers who have no idea what they are doing but they pretend like they are making a lot of money. If they truly made so much money with their trading, don't you think that they would not be asking for money from strangers?

I would suggesting staying far away from these "influencers" who offer something in exchange for your money. Its never worth it.

The only way to make money trading is by learning how to trade. And if you need to practice then there are money sites that offer dummy-coins on a dummy-exchange that you can practice with. Or just do thought-trading by looking at charts and documenting your "virtual" trades.

When you feel certain enough that you can make money, then and only then should you trade with real money.
