What is the procedure for this? Do you have to risk your own money, or will they send you money to bet on a certain game as per their instructions? I'm curious because if they require you to use your own money and claim they will ensure you win, it sounds like they might be trying to scam you, and it may not be related to any legitimate syndicate or organization.
Nah you won’t get to use your money, you’ll give them the login details to your account and then they’ll find it and start using it for what they want to use, they might even use it to perform some other things that the casino might be against leading to your account getting blocked.
And another issue here is that once they get your login details, there’s no guarantee that entry won’t change your email and login details into something else, so you don’t only risk your integrity with the casino you also risk losing your account permanently if they eventually change all the details in it.
