Everyone has their own reasons why they are gambling and I think if this doesn't hurt us in any way, we should let them be and just respect their reasons. I personally gamble in casino using fiat and even gamble online and it is only for fun and not because of earning money. I have limitations to myself and doesn't come to the point where I have a debt due to playing, and I thinks most people who play have the same reason and perspective over gambling as mine.
