Hey Haliffa,
you are quite correct about what you say for the casinos but this is how it is. Probably the thing is that the people go to the casino with the clear mind that they will lose or have a very small chance to win. Which the scammy brokers promise things to the clients that can not become reality. Do you understand what I mean? The casion does not tell you: Welcome you will win 90% of the time. But the scam broker says that over the phone…
So it is not about which one is riskier, it is about who misleads the people more.
