Being an investor in a bankroll can indeed provide many advantages but you must know that not all gambling places can survive and have players because there must be good news or good events that can trigger gambling players to enter and often hold promos that do not harm gamblers and do not harm the place gambling.
As long as they can find a good gambling place, they might be able to invest there but this is a new casino we don't know if they can last long or not. Maybe if the casino can last a long time, it will be our luck because we can find the right casino. But if not, then it is our fault for investing in a new casino. I suggest not investing in advance if it is a new casino as they still need to develop the system and maintain it and work to earn the trust of its users. After they can be stable and get a good reputation, we can try to invest with them but don't use a lot of money because it is very risky.
