I was about asking, what's the difference between a real bitcoin and other cryptocurrency casino and a Casino that allow users to deposit and withdraw in crypto - pretty the same if you ask me.
But from your second paragraph, it seems you are asking about casino where a user wouldn't have to register to play, I want to understand if the casino you mean is like a decentralized casino where users would have to connect their non-custodial wallet to the casino to play, or are there other type of casinos that are available that doesn't require wallet connection and also doesn't require registration.
I am really curious to know, answer/wit a bit of explanation would be greatly appreciated.
This! Bitcoin is also a crypto. Maybe it will be more valid if he says blockchain-based casinos since they can differ a little to the usual crypto casinos that we see around these days. A real crypto casino can also mean a casino that only accepts cryptos. They don't have stable coins, they don't have third-party payment providers which accepts non-crypto deposits.
You are right there, decentralized gambling sites or also called as web3 casinos are plug-and-play. They don't have these sign up process which takes time but I heard that some of them are not exempted to KYC verifications, so we should wary if our goal is to play gambling anonymously.
