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.
I guess that we will see that some or just a little number of them that does it for their own satisfaction. Not judging with any of them but in every religion, there's like the black sheeps that are in that form.
It's a small herd and that's why the respect must be there for the majority because in every religion, the number are just few to those that are not dedicated in following their laws.
Gambling is haram, but people still gamble because they don't see it as haram.
I am confused, they knew it that it is haram but they gamble because they don't see it as a haram. I think these are the people that I am talking about as the blacksheeps.
