I do recommend the casino to them, and I tell them about the crypto payment option. But most times, they are skeptical about using it because they hold onto their crypto dearly and barely experiment with it. Only a few try it out to see the advantages it offers over using cash. But most of them are always hesitant to give it a try with their crypto.
They're doing the right time because when they start using their cryptocurrency that they're not attached to as they're attached to their fiats, it'll become easier for them to start gambling more often. I have also recommended some cryptocurrency casinos but people I tell aren't much into gambling hence they won't want to try risking their cryptocurrency being lost but won't mind gambling with fiats when they're not strictly cryptocurrency casinos.
Any cryptocurrency lover that's thinking about starting a casino, shouldn't make it strictly for cryptocurrency but they can allow gamblers to have multiple options of deposit because this will encourage more people to be gambling instead of them being discourage because they don't have means to deposit money into the casino.
You're right—crypto adoption can be a hurdle for many, especially when people are more comfortable with fiat currency. It's essential for crypto casinos to offer multiple deposit options to cater to a broader audience. By doing so, it reduces the barrier to entry for newcomers who may be hesitant to use cryptocurrency for gambling. Once they see the benefits of crypto transactions, they may be more likely to continue using it in the future. A diverse range of deposit methods is key for attracting and retaining users.
