A market, while it would help with some of this, would lead to the same general issue: if I want to sell something for $100 each... I have to get the money somewhere. So I sell for DVC, then sell the DVC to get money so I can get more items to sell.
A game would be different, in that you don't necessarily need to keep converting to fiat to keep the ball rolling. For example, take Facebook's credits (or any F2P game for that matter). There are millions of dollars being poured into the fake currencies to be used in the game. This is what we really need -- something that gives the DVC true value without requiring us to keep cycling it straight back to fiat just to sustain the process.
But assuming that's correct, by saying there is no true value outside of converting to btc that implies that - at least as of now - the visible rewarded projects (primarily devtome) have no intrinsic value, because value is underwritten by rewarding or paying for those projects undertaken. And so if that's the case why are writers being paid in dvc when to realise any value they will convert it to btc?
