I have to say instead of investing into the bankroll, I would advice you to start looking into casinos that are decentralized, there are tokens that allow you to be the owner of the website, the more you have the bigger share you will get, and that way there are possibilities of making money without being at the hands of an owner. Don't get me wrong Ethan was great but not everyone is Ethan and there is no reason to risk it neither, if you invest into a decentralized casino and get their tokens, you will get your dividends here and there and that will help you out a lot and you can use those dividends to buy more and more so you can basically increase your share in that casino.

It is difficult to pick a good one because they lack marketing and rarely have a lot of gamblers but I still think that it would be better than investing into someone's casino if you do not know that person.
