If stake is not a big casino then who is in the cryptocurrency space. With primedice and stake they one of the casino which attracts huge whales and on a daily basis you will find big whales wagging around $30 to $80 million give or take. Sponsoring a sports team is cool but what attracts more whales and gamblers is when you give them back in the name of rakeback reload and boost and there are daily races and with every progress they will give back a percentage.
Your numbers don't sound right. If whales were wagering that much daily, then since a good amount of those bets will be lost, Stake will end up with millions of dollars of earnings, each day. If you tone your figures down a notch to $30 and $80 thousand then that's more normal wagering volumes.
