VirWoX stands for Virtual World Exchange and is an exchange dedicated to buying virtual currencies. Interestingly enough, it is older than the first appearance of Bitcoin on exchanges since it began in 2007 in Austria as a centralized digital currency exchange.
At its core, VirWoX is designed as an online exchange dedicated to buying virtual currencies that you can use in online games. Via a loophole, however, VirWoX has come into the limelight by making it possible to purchase Bitcoin via PayPal, although doing so does require a few extra steps.
