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.
