Besides Facebook groups, there are many Telegram channels that provide free trading signals. All of them have their own profit.  And those who trade following them sometimes get profits but sometimes face huge losses. So believing them and following them is the greatest folly. When it comes to trading, your research is of course the most important. A person who does not have confidence in himself but trades by copying the trades of others. They can never gain anything good from trade. Maybe they get some profit for a temporary period but it doesn't last long
