[Question] Pros and Cons of Crypto Currency?

The other obvious factor differentiating cryptocurrencies like Bitcoin from other digital currencies is that theyre generally decentralized. No central power (such as a group of video game developers) has arbitrary control over the money supply. World of Warcraft, EVE Online, and Second Life all have servers, which the developers can manipulate at will (or shut off entirely), but Bitcoin runs on a network of participating computers that agree to the same standard.
