I think people are buying them because it has potential and have a great future with it .and some people buy it because they want to convert it into bitcoins in the near future.
You are very late on this one,you should do a research ,there were at least 3 dedicated threads on this about ebitz as a scam coin,there's no use to defend it it will only hurt early investors,for saying this is till a good site to invest and people might fall on this one also..
