When playing poker in the land based casino it is customary to use chips instead of money. This is usually to ensure that while in the casinos you do not go around with a lot of money in your pockets. However, in the online casinos, one of the advantages is that you do not have to go around with either the money of the poker chips, since you can see your account at all times and then you can decide how much to spend.
This advantage makes extra sense if you are indeed a high roller at the poker tables, but you do not like to carry poker chips around with you wherever you go. Hence a good alternative is the online casinos, where you can play with a lot of money and not be burdened by the masses of poker chips that you acquire. In this way you can play for extended periods of time and win a lot of money and not go around with the poker that you win. This lends the game a certain amount of ease and elegance that cannot be matched even in the land based casinos, where you have to lug around all your poker chips.
