Based on my understanding it is undoubtedly that gambling is haram on their beliefs and we should respect that belief. I am not a Muslim guy but I haven't heard here in our locality wherein they were involved in gambling activities or even online I didn't see one so far. With crypto gambling we really have no idea what religions are involved on there but it is their own decision and risk to do such activities.
Gambling is haram, but people still gamble because they don't see it as haram. After all, according to them, it is a pleasure like any other pleasure. We can't say much about this because it will depend on each person. If they know that gambling is haram but they still gamble often, that's up to them and whatever reasons they say, it still depends on the judgment of those who gamble. We also cannot force them not to gamble because it is haram. After all, that is a decision they have taken and they should be able to take responsibility for it later.
Exactly! , its not that we are depicting their religion, but let's be honest, some people or most of the people out there that do have their own religion sometimes do the things that are forbidden in their religion. Yes, it is stated in their religion beliefs that this thinc is bad or forbidden, but according to human nature, they will tend to do things as they can't control themselves and they can't fight the urge. And gambling is one of them. Like the OP said, gambling is forbidden in their religion, but they still do it. Why? It's because they can't control themselves, and let's face it, not all people could be as disciplined as the other members of their religion. What should they do? Make it a secret. Yes, maybe the god or the person they are worshipping might see what they are doing, but we can't do anything about our own desires or decisions. If we decide not to follow religion, then it is. The same goes for gambling. As long as we can't control ourselves, even if we stay in the religion that gambling is forbidden, we will still do it.
