I feel this currency is more like eGold.
e-gold (deliberately spelled with a lower-case ‘e’) was a digital gold currency operated by Gold & Silver Reserve Inc. under e-gold Ltd. that allowed users to open an account on their web site denominated in grams of gold (or other precious metals) and the ability to make instant transfers of value to other e-gold accounts. The company was founded in 1996 and had grown to five million users by 2009, when transfers were suspended due to legal issues. At its peak in 2008 e-gold was processing more than USD 2 billion worth of precious metals transactions per year [1], on a monetary base of only USD 20 million worth of gold (~2.54 metric tonnes) [2], indicating an extremely high monetary turnover (velocity) of about 100 times per year (similar to M-PESA). e-gold Ltd. was incorporated in Nevis, Saint Kitts and Nevis with operations conducted out of Florida, USA.
