like everyone else said moneypot is decent but i personally suggest you to not invest into a bankroll because theres always a chance someone will win and you will lose everything.
Every gambling site always have some big whale, actuall that is a good way because when they lose we will earn money. And you know that in the end house will always win so there is no way investment in gambling site will lose because this is a long term investment so you really need to take times when you invest on their site
From my personal experienced about investing to online casino, I would say that you can have peace of mind with your money being invested to them because you know that the house edge is at your advantage. However, there will always be instances that whale players will be playing and very lucky gamblers winning big profits - which means, you will be losing some profits or will be on a negative profits. However, if you just keep on investing regularly, you will be on profit at the end of the day.
That should prevent the site from losing too much bankroll.
But the only problem with a lot of scripts of the casinos now is it will make you win then make you greedy to invest more then they do it in dirt way! Loosing all of your investments to its. Luck is the best weapon when it comes to gambling.
