I have personally known several Muslims who have violated haram. In my opinion it is not about cryptocurrencies that help them to circumvent gambling bans, but about their unwillingness to follow the rules that they agree with on the one hand, but when it comes to them they do not follow them. In my opinion, the strength of faith is different for everyone and religion is not able to completely limit a person in something. This applies not only to Muslims but also to other religious denominations.
I get what you're saying about how strong someone's faith is kinda depends on the person. And yeah, religion doesn't always stop people from doing stuff they shouldnt. but I kinda think cryptocurrencies make it harder for some folks to stick to their beliefs. and These things are decentralized and anonymous, right? So it's easier for someone to gamble without getting caught or told off by their community.
Now sure, there's lots of Muslims who use crypto in a responsible way that lines up with their religion. But we should admit that this stuff poses unique challenges for religious folks trying to walk the walk.
