That's the most insane offer I have ever seen, and I don't think that any casino can afford to pay $5000 for each referral. I smell something fishy about your referral program because if that's the case then there are many users who can easily bring 100-1000 referrals without much hassle.

I don't think that bring 100 users will allow them to earn $500k because that isn't a small amount and how could a casino pay that much to the users who bring 100+ referrals? Are there any hidden terms and conditions behind your referral program? I don't know why but it doesn't sound genuine to me.
