With that in mind, if you have little capital, don't open a casino. This is a business principle. If you have weak finances, it's very difficult to survive because your money will be used up by marketing and other operations. It's very rare for a small casino to become very large without substantial capital to start and attracting a large number of customers by hiring marketers, whether influencers or other similar companies.
I agree with you that casino operations requires large capital to start up since everything that relates to running a casino in capital intensive, since unlike other businesses that need low marketing to draw audience, running a casino marketing is not like that, since as a new platform, one will need to carry out aggressive marketing in order to build a space for themselves in the market and there is high competitions which make revenue generation very important to sustain a strong consistent presence.
