If the answer is yes, then it's a true Web 3.0 casino, if it's no then is just a centralized normal web2 site like the others.
Web 3 is decentralization, by definition!
The fact that some claim they have a web3 product and it turns out it's not a decentralized one, it doesn't mean the definition has changed, it just means they are liars trying to create fomo on a buzzword.
The fact that it can't be achieved in the current format by most of our websites it's pretty normal, decentralization has limits, and torrents work perfectly without a main site, but you still need a central point where those are distributed, tor works like this because it's a simple tool that doesn't need anything else just pass information from one point to another, with casinos you will need people to add games, people to maintain odds, people to be in charge of payment wallets, each one is a point of centralization and that is not doable right now.
