It's peanut for Casino and sportsbook. A large casino should have millions of dollars of bankrolls. Stake spends over $6k per week. It's not just the gambling companies but other services are doing the same.

If I am not wrong then Chipmixer is spending over $15k per week. Best change is also spending over $4k per week. Of course the conversion from the community worth a value for these companies. Mainly they want to see their name all over.
