It's simpler than you think. Any trader can set up their account to copy signals from another trader.
Then, they connect that same account to a PAMM system and start accepting investments from others.
All they really need to do is pick an account to copy. No actual trading knowledge is required
I don't understand how you can be so sure that if you copy the trades of other traders, you will receive a guaranteed profit. Everyone makes mistakes, and at some point the trader whose transactions you copy will make mistakes, and this will lead to the liquidation of your deposit, and consequently the money of the investors who entrusted their money to you will be lost.
That was a mistake I made when I was first learning about trading and just starting out with real money. You understand how difficult it is to learn everything about trading, especially market analysis. It's incredibly difficult, and that's what led me to try trading by relying on predictions from other people in groups or channels.
Initially, I was profitable, but over time, the results changed drastically. The average result per session was a loss, and it even led to me experiencing a trading loss. After evaluating it, it's true, as you said, that there's absolutely no guarantee of profit, regardless of whoever's predictions we follow. Now, I prefer to trade independently according to my abilities and knowledge.
