When Olympus added betting you think they didn't know people would try to make money off it? At the end of the day, betting comes with the risk of losing your money just like runs. @Birb lost a billion dollar bet the other day, and quit the server. It's all luck, and if they choose to go down that route and make money, props to them.
Betting is way riskier than doing runs, so why shit on the people who enjoy it?
