Derivatives are by definition derived from something. MSC's worth isn't derived from anything. Therefore it isn't a derivative, and since it doesn't have nearly the network advantage Bitcoin has, its just another crapcoin, only marginally more crappy than the others due to the fact that it also bloats the blockchain.
Not true, Mastercoins worth is derived from the bitcoin block chain and the features made on it through the protocol
What an idiotic thing to say.
MSFT is moved on NYX's exchange, that doesn't make MSFT a derivative of NYX.
Mastercoin is moved on Bitcoin's blockchain, that doesn't make Mastercoin a derivative of Bitcoin.
