The problem is buying and buying does nothing if there's never any value added. DVC still, for all intents and purposes, has no value. It has to create it. DVC has to be treated like a business. If I opened a store locally that earned $0, people wouldn't invest. If it was profitable, they would. DVC is the same way.
Ofcourse. We need someone who sells something valuable and accepts Devcoin for it. That's how you create a devcoin related business.
