meanwhile gambling is illegal in some of those countries and I can't stop to wonder what an irony this has become.
The reason is simple
(the basis of religious evidence that makes gambling prohibited), in some countries, although, followers of certain religions are football lovers in general, for example: football lovers in Iran, Qatar, Saudi Arabia etc.
That's why gambling in certain countries is prohibited, even the majority of the population/government in that country football is included in the legal of the country, even though gambling is prohibited, I bet they are also involved in gambling secretly, you will understand what I mean.
So, in this topic question, i think gambling and football should be separated, the problem is very much different, even though people really like soccer betting.
