This requirement alone would not allow me to pass, so I'm not one of your target markets here. Actually, I don't believe you'll find gamblers here who bet $1 million, as those who are gambling such amounts are probably not active in the forum posting. Therefore, you are unlikely to make them use your codes.
By the way, what do you mean by this?
It's true that typical poster here in the gambling section can't reach this kind of wager requirements im 7 days but still there's still a lot of user here that is silent on the forum but high roller in the casino like Realwinner, MrBrightside and Roycilik which I know that they can wager more than 1M in a period of 7 days.
Don't underestimate the forum user since there's a lot of whales here that just lurking on the post silently.
