I want to believe that by "casino capacity" you meant the management of the casino since a casino itself can not handle a community, it's own community..
What I meant by capacity to handle the community is that, the rainbet casino have come to stay and gaining a lot of ground and their loyal players who make up for the community are increasing daily as their visibility keep increasing, so for sure more traffics equal to more demand on the platform so development to meet the demand will be most priority for such a platform and at that point rainbet have build such a capacity since we have not read any negative feedback on this thread as regards to their services.
