Land based casinos have their own charm. In current digital era, there are still many who prefer theatres over cinemas, paper books over reading from the screen, IRL conversation over phone call or chatting online. As all people are different with different needs and opinion, there will be always need for land based and online casinos. Land based casinos is a totally different experience than online gambling, even though people same things.
There is a difference between land based casinos which are traditional casinos against online casinos but taking about profitability and durability, digital casino will last longer than physical casino. When I want to get a real feeling of gambling, I can go to physical casinos but when I want to play for money, I do it online. Physical casinos can make you enjoy gambling because you will be surrounded by other people and you will want to socialize and have fun. Digital casino are more easy to maintain therefore there will be more created as physical casino will be physically not possible to move around and more costly to maintain or build in other states but online casino can be used all over the whole world as far their governments do not have anything against gambling in the country.
