That is something that I believe much people ignore about small or new casinos and gambling services in general. Regardless of the size of the casino, they will always allow one to gamble relatively high amounts of money and use big multipliers, for the sake of them having a chance to get their initial investment back and continue to grow their business, it sounds normal; I would not expect a casino to tell me I have deposited to much and I need to withdraw because they bankroll is small, thst would make anyone to feel unsure on the integrity of the casino and just quit gambling there.
Since a business of this kind cannot afford to turn away big gamblers or high rollers then they need to give high priority to their bankroll, so they are able to pay wins and further increase their reputation among the community.
Having a a bigger bankroll for paying winners will come in the initial detriment against the budget for art and Interface of the webpage. To me it is about setting priorities.
