When we started dappcasino.io, we only listed real decentralized casinos "gambling dApps." These allowed players to send money directly from their wallet, and if they won, the money went straight back to their wallet. But most of these casinos had big problems. They were slow, full of bugs, and hard for people to use. They mainly worked on the EOS network, but sadly, none of them exist anymore.
Today, many crypto casinos say they are decentralized, but as others have pointed out, this isn’t true. Once you connect your wallet to the site, you lose some control.
There is potential for decentralized casinos, but the risks are high. Right now, the talk about decentralization is just marketing.
