in the past, I already saw this, one person claim that he has the best way to earn a profit and our jobs is only predicting the rise and the fall. for me, it does not work because I think this depends on luck although there are need the skill to know where is the trend will move. I think it's not good if you want to try and it's better to do trading because you can learn some skill about trading and you can earn a profit. I don't know if they are really paid or not because I never try to join with them so you need to be careful if you want to join with them.
Yeah if you have big money to trade in crypto then you can make big profits, but keep in mind that trading is not easy. It needs experience, knowledge about the market and skills to trade in the right time. These are the qualities for a good and successful trader. Good trader can make big profits even from small investment and bad traders can lose big investment if they have no idea of the market.
