You looked like a big broker who made attractive offers to us. I have ever seen the offers like this and the end with a scam because the broker can't handle another fixing mafia score. As I read how this job works, you need at least an extensive network between mafia scores to set who the winner is. because if it is there have a different argument, then you need a large capital to cover and submit the winner to the owner club or manager.
as a small gambler, I'm certainly not interested in your offers, I'd rather just a play common by looking at the previous match of the club I choose.
Most probably a scam attempt because you won't find people interested in making large bets on fixed games surfing around the internet looking for people to help them with it because they would already have their networks and people who would do such things for them. Money can do anything, if someone says they have a lot of money, they are into shady stuff such as this, but still are looking for people or partners then understand that they are lying because you don't go out hunting for partners in such cases.
Just like you, I would never be interested in an offer like this, and besides, we can't have any information about fixed matches because such information is not publicly available and only someone who is involved in fixing a game can know about it and it can only be revealed after it is done that the game was fixed. So I don't know why OP thinks he can find someone who will provide them with such information and get themselves in trouble.
