How many players one place has doesn't showcase how much they profit. There are tons of stuff like how much those players gamble in total and how much the costs are. Revenue minus costs equals profits, we have literally neither of those numbers, we don't know their revenue, we don't know their costs, which means we don't know their profits.

Just because we know there are new players or old players with new names or how much certain players wagered doesn't mean we know the full picture. Long story short we really need to find out a lot more about bitdice operational finances in order to claim if they can continue operations for years or not, since they don't need to publish such personal information, we will never know how great they are doing ourselves.
