No, I dont think so. This will affect the casino's business. Casino earn big profit from people who gamble with large amounts even if its bit by bit. If they government set a daily limit, those players wont be able to spend the entire money on gambling in one day. And also, even if it was effective, it wont reduce gambling addiction in the country. Addicted highrollers will create as multiple account, making sure they spend the entire money and get satisfied.
