With the changing world, everything is moving online so why gambling would remain traditional ? Right now we have both online and physical casino, but soon the time will come that it will be hard to find any physical casino as online casino are more economical and beneficial to both the players and the owners of the site.
Sometimes, for the gambler who is familiar with traditional gambling game is not easy to move online because they need to adapt the game, the situations, the feeling which is important to them. They usually meet many people in one place, talk to each other while they gamble, drink together after they finish the game, keep reminding each other to quit gambling if someone has lost control and others.
Perhaps, they will lose that feeling especially if they are trying to play gambling games online and they need to change their perception about gambling games. But for people who were already playing gambling online, they feel that playing traditional gambling games is not too attractive or they are too shy to meet other people in the gambling table.
