The inventor, Sean Worthington, has indicated that marketing efforts haven’t even begun in earnest. Yes, DFN has been promoting it somewhat along with other ventures they are involved with. However, I think CDC is interesting in the fact that the tokens are in the process of being minted, which simply means that they are being dispersed. I can offer you a CloudCoin right now in exchange for anything that you have of value. There is nothing complicated about it. I send you an email with the data for the coin(s) and you take ownership as you promise to deliver on your good or service.
There are 2 million tokens in denominations of 1, 5, 25 and 250 and there are 8 million tokens in the denomination of 100. All of the tokens have identification that will be authenticated in a process of transference from the owner to the recipient. Once the recipient has taken ownership, the previous owner can no longer use that coin - it will not be authentic in a future transaction.
What the marketing efforts will need to focus on is getting businesses to accept them. The businesses will obviously want the value tied to some known commodity. At first, it may be the fiat currencies around the world, but over time it may graduate to a precious metal standard until the coins can stand on their own integrity and acceptance.
