Jimbob...you read our Monero Research Lab's very first publication, right? You know the one where we spoke about a cascading privacy failure if an attacker owned sufficient outputs? Here's a link for you to save yourself. At any rate, this could occur in a CryptoNote coin where persons unknown to everyone else controlled, to thumb suck an example, 82% of all the outputs. That would be an exceedingly unsafe CryptoNote coin to use, as those person(s) could easily reveal the actual signature of just about any transaction, thus negating any benefit of ring signatures.

When choose a currency to shill for, you really should choose one that doesn't have that flaw.
