If @OP can add more coins, I think he can still promote his website because I see only ethereum used to gamble. While the ethereum price now is at a high price, maybe many gamblers do not want to use ethereum to gamble. They will choose the other altcoins that do not need to pay a high fee and use too big money in ethereum to play any gambling games. But maybe some gamblers who have a lot of ethereum amount to still playing gambling.
Thank you for your response.
The feature you're asking is actually not as good as it might seem.
Right now the casino is completely self-contained. It doesn't require any centralized backend (a single point of failure) to work. It's only the smart-contract and the frontend (which I sure too find not very visually appealing).
The player uses their ethereum wallet (like Metamask or any mobile wallet with WalletConnect) to connect to it and send transaction directly to a blockchain.
What would it mean if we introduce another coin as a payment method? There are two scenarios:
1. We use wrapped representations of coins of other blockchains inside Ethereum (like WBTC). Players still interact with the casino by their Ethereum wallet. The casino would continue to be decentralized.
Yes, this is possible. But you would still need to pay transaction fees with ethers. Problem doesn't solved.
2. We make a real use of other cryptocurrencies and other blockchains. But it is impossible to achieve without adding some kind of central point, that can operate over multiple blockchains at once. But we can't, because this would mean, that you now have to trust the casino. It is no longer decentralized. It can be attacked by hackers at any minute.
This is an interesting topic to think about. If you're using some gambling platform that offers you such an ability to use multiple cryptocurrencies from multiple different blockchains - you're actually in danger.
You don't know how well they secure your funds. You believe they do it well, but who knows?
You don't need to trust Honest99 - that is exactly what the title says.
