I might not contribute much to your question but, I'd like to point out that buying scripts for any type of "business", be it Crypto Casino or any other type of internet site, in an already over-saturated market, is a poor choice! it's both a waste of money and time, if you're not capable of creating one/finding the people to create it from scratch (and therefore be able to compete with those who do), it's very likely going to end up dead very quickly! I would suggest trying to both combine the already existing "casino" ideas with some new type of idea (not every type of casino game is available), and therefore you're both unique and with a functioning site.
Thanks for this thoughtful response! I totally see what you mean here, and I agree that this makes sense -- just buying an off-the-shelf thing in a crowded market seems like a potential race to the bottom. If there is anything you take away, OP, it should be that you need a differentiator.
Crypto Casino is a form that will grow in the future because of its effectiveness. Previously used cards to bet, the use of crypto to play directly will be effective and faster. This is a direction that will be developed very soon.
