I agree that gambling and casino are popular in all the market conditions. People always want to try their luck. They always want to earn more money but to work less and less. That is why casinos are so popular and in demand.
Many people want to check their luck. That is why they continue to play casino in all the economic conditions. Easy money always attract a lot of people because nobody want to work much but a lot of people want to have a lot of money without working at all.
