Is it safe to say that casino platforms is running their business with users find only? I read somewhere that they pay winners with losers money, I couldn't ask him or her if a casino can start business with zero fund at hand, I know that most of them wired their system to favour them more ( lose more and win less ) , if not they will run out of business fast I belief, what do you think about this? Was I wrong about this? Come to think of this, there is no prove that they have some money to pay winners.
To be honest, I don't have a proper answer to your question.
but I just want to underline what you said, regarding casinos starting a business with zero funds at hand. don't get me wrong, it's impossible. I don't know what the basic mechanism is, but at least if you want to build an online casino you need quite large financial logistics. why, because to build a casino you need a big bankroll. first of all, you need funds to build a site and that costs money. whether it's domains, hosting, scripts, and all kinds of things. plus, you need a license so that the casino you build becomes a legal casino. you know, at least you need big funds just for a license. well, I'm sure, now you have some conclusions or descriptions related to your question.
