...most likely ordinary players who do not have problems with gambling addiction will suffer.
I agree, especially those people that can take those losses ten or even maybe a hundred times the set cap by this regulation. I don't think they will be willing to face an ombudsman just to prove that they can take a loss since that might affect their persona negatively knowing that they are gambling like that and in that huge amount.
This is a law that does not benefit anyone and at the same time it affects the majority of gamblers that have their gambling under their control but that now need to follow this dumb regulation, and if you really think about it you will realize that the law is completely pointless because those that are addicted to gambling and that are losing huge amounts of money in it will find another way to gamble or they will find another way to lose their money and at the end they will end up in the same situation as before.
Based on what you said, if this is widely regulated it would also affect the country's economy. Some countries are also getting a lot of taxes from these casinos and online casinos and I think if there will be a regulation like these in a lot of casinos or online casinos, I guess it would affect the taxes the government are getting since these people that you say might find a way to gamble and it would end up illegal..
