Web 3.0 is definitely goin to create several cores of centralisation, as well as its crypto part. Thats why it happens. Any service introduced to the market tends to monopolize and become uniformed, so web 3.0 casino is just a kind of ad campaign in order to creators to take part in gambling market.
A perfectly accurate remark about monopolization.
Now many of our colleagues and lovers of cryptocurrencies and fans of talking about the decentralization of the Internet love to talk about how great and free it will be when web3.0 covers the entire planet! And everyone will be happy. However, I also think that this concept has much more advertising and real decentralization, even having been born sometime, at some point it will still be controlled by some specific people or groups of people over time.
This is an inevitable process and no one can stop monopolization.
So web3.0, in my opinion, is also just a cleverly invented publicity stunt for too naive Internet users.
Web3 or Web 3.0 is only just a concept so far, and there haven't really been any actual use cases of it or any developments going on with it. Any platform or project that says they are utilizing web 3.0 for its services is simply lying about it. They are just riding with the tide since web 3.0 and metaverse are some of the most hyped trends of today.
We will have to wait and see once the technology is actually live and being used around and then only we can decide how much decentralization it actually has and how centrally controlled it is just like the second generation of the web which is called Web 2.0.
