I Think This is a business, there is always an opportunity to make a profit, one example is the service above. When the world of crypto becomes large because bitcoin is the most expensive digital currency in the world, they sell paid services that predict bitcoin price movements. To become a member, you have to pay several US dollars for one period. When their predictions are good, of course there are no problems, but when a lot of problems are lost. Because this is business, satisfaction means profit and loss means no customers.
