Human nature, thats the culprit of addiction. We dont get satisfied how much we earn. sometimes we earn some handsome amount on those gaming sites but the addiction to play more and more results in losing all we have there, we all know ultimately we will lose there despite how many games we won before. Secondly, some sites don't provide instant withdrawal facility so we get forced to play more there, those ones are also the culprit of our capital loss because of this I chosen vegas because they provide instant withdrawal so I can control my temptation to play more after withdrawing amount and do some fun in real world with the help of earned amount instead virtual world.  Plus they give so many exciting offers to new users and on monthly deposition its most trustful site out there that offers a variety of games.
