Most people with betting accounts use credit cards because of the ease of the transaction. Banks treat deposits into gambling accounts as cash advances where the deposit puts the credit card into the red. So the most common way credit cards have been used is with a positive cash balance. Problem gamblers on the other hand get their hands on as many cards as possible and max them out. A gambling addiction is probably the worst kind of addiction to have because the currency of the addiction is money: the person's own, then sometimes other people's. Reforms to reduce the capacity of problem gamblers to commit financial suicide are by and large a good thing.
