CUPRUM Coin is a start-up cryptocurrency project that will have a specific physical underlying asset as a backup, an ultra-high purity nano Copper Powder. It is one of the most expensive elements in the world with end-consumers like the aerospace industry, but it is used mostly as a financial product due to its extreme and stable value. The world’s largest banks use it as collateral and as an investment instrument, which is not available on the open market. With our CUPRUM Coin we will create a marketplace by providing a blockchain enabled trading platform.
