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.
It makes sense that many people are hesitant to use their crypto for gambling, especially since they hold it closely due to its value and volatility. Crypto is still a relatively new concept for many, and it can feel risky to use it for something like online gambling, even though it offers benefits like faster transactions and anonymity. It may take more time for people to feel comfortable using crypto in these environments. Perhaps providing reassurance by sharing your own positive experiences or showing them resources on how to safely use crypto for gambling could help alleviate some concerns.
