Online gambling can never affect the physical gambling, because am sure till date there are people who prefer the physical gambling to online casinos because there is absolutely a huge difference between both two. Because just as online casino gives you the privilege to gamble right from the comfort of your home, the physical one gives you the privilege to meet new people, make friends, exchange contacts, and possibly meet experience gamblers like you which at least you could learn one or two new gambling tricks which the online gambling casinos can not offer. So both has its advantage and disadvantages, and it is left for the gambler to choose which one suit him the most.
