Many people are into online gaming now. Some even buy points or buy cheap wow gold or other game currencies so they can do better in the games. Others make money selling these coins. Still a few smart others have found a way to make money helping others to buy and sell this online currency. They set up a site where people can feel safe and list their currency for sale and where others will feel safe with their real money buying these points and coins.
I do not do a lot of online gaming but I have on occasion bought points to get something I wanted in a game. I have also bought virtual money to get things for my avatar in a virtual world Some still frown on this but I see it differently. This is entertainment. People pay to watch television or to use the internet. They will pay to go to night clubs. Others pay to read books or listen to special radio and music. Go On Studying
