POS sucks big time. It needs to be earned. Green, earth friendly, whatever can go to hell. A coin will not have any value if its not earned. about the con mixing.... I believe introducing it is not going to do anything to make it more valuable. It will just fall into the current fad of "anonymous" coins. I also don't understand this paranoia about anonymity. Isn't it enough that an send/receive address is not linked to a person's identity?
