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.
I chose to compare with my own expertise, what you call is a kind of tool to be more detailed in the same strategy, I have not refused so far, but it is still not recommended, only to be more vigilant because the majority of them are only temporary PnD groups.
Some of the signals I read are not constantly accurate, but if it matches my analysis, a small portion of profit can be withdrawn, even if the market is in a bearish condition.
