Translation : At the moment, Mastercoin and XCP are only parasites from bitcoin dev's points of view...
Sorry for being so direct but this is what I read as a non-technical investor.
Thats how I see it too. The arrogance of these guys is amazing. MSC and XCP is extending the functionality of Bitcoin and may be something good have and compete with NXT, Bitshares and Ethereum.
XCP can move onto other chain, or I suggest get its on PoS chain. This will also prevent the archaic 10 minute wait.
