It's absolutely insane how big money some players are wagering recently. As per my understanding, vault balance will be even higher on a daily basis. I like Chips and I'm really hopeful about it. Nice to see it, your vault balance which should be long in course of time.
They might've earned a big profit so they wanted to splurge a little bit more on gambling but you are right that it is puzzling that they spend a lot of money in gambling. Chips is a pretty fairly new site so I think that they will be able to survive for a long time, if they continue improve customer service and their games.
