The Internet has offered many opportunities for people to invest in alternative forms of currency that appreciate over time and let them make real world profit.
One of the earliest examples dates back to the early 2000’s with Second Life, an online world developed by Linden Labs. This online world has an its own internal economy and currency named the Linden dollar (L$). In 2009 Linden Labs reported that the total Second Life economy stood at US$567 million, about 25% of the entire U.S. virtual goods market on that year. Another virtual currency on the rise are bitcoins.
However, the hottest virtual currency for 2012 appears to be SWTOR credits.
