This Betfury platform is something unique, on one hand it uses bitcoin and cryptos for rewarding, and on the other hand it is always a good thing to have when project is expanding decentralization, rather via games, or any other category, the more people pushing for blockchain use the better.
I am not exactly sure what you are trying to say here but Betfury isn't a decentralized casino. In fact, 99% of the casinos you can name are probably centralized. That's the standard. Decentralized casinos exist. They are an alternative but not nearly as popular as centralized gambling sites. Think of all the ads and sponsorships you see for popular sportsbooks and online casinos everywhere: all of those are centralized.
