I just follow the signals and never put really big amount for trading so I didn't loose much
Yeah that’s the best trick possible to be safe from getting loss.
But the OP’s question is how to earn profit. And tbh if you want profit then you need to take the risk.
Again you need to take calculated risk, else there is higher probability that you may face losses.
Op can see some tutorials on YouTube at first in order to know how the market affects and yes if you can join a paid signal group then surely you will get some legit calls.
I have heard many times that these signals work . So it’s better to give yourself a try.
Wish you good luck OP.
