The key points why people don't use other coins to do a market are the same, nobody develops the market. Generally we can't even trust javascript for anonymity. And I believe that's the major problem for a decentralized market. there should be some sort of application, that connects trough tor, much like crave is trying to do. But if there's not a decentralized market system (you can put your thing to buy/sale). maybe there will be a really decentralized market, but I don't see that on the code. What I see is that the node acting as market must have 10k crave. That's not solving the problem... you could put a multisig option in some other coin (shadow or whatever) that's just the software interface. The nicest thing I saw was in #bitcoin-otc, you can choose someone to escrow you, and validate his credentials trough pgp... there's eventually a decentralized web of trust (using pgp, maybe if we can put the pgp in the blockchain, like a distributed db or so) So there it is, a really decentralized anonymous market. I could be wrong and crave's developer has that already, but that's the most difficult part in a p2p market.
