you sounds like it is very easy to do. you can make prediction about the market without an technicial knowhow but when money is involved, you better e careful to avoid loose of funds. this market could be deadly especially at the bear market.
Many people are doing this business in bear market. They open a whatsapp / telegram group, give the predictions/Signals and earn money from the paid members. I never like this kind of approach from these people.
In reality it is not easy to make money in bear market.
they trying get benefit from beginner investors and trader.selling signal meanwhile their trading skill didn't good enough.i am often to see this kind of group.better to improve our trading skill so we could survive without depending on other people.
