Cryptonote has a variety of issues that would make it incapable of surviving for long..

The bloating and scaling issues are very severe, along with the fact that just about anyone can simply fork Bytecoin, and make there own Cryptonote coin, just like the devs of Monero, HoneyPenny, Quazarcoin, and FantomCoin did(all bytecoin clones).

They're all the same and have the exact same features and code since they're forked from Bytecoin, with just different names, no innovation=no future.
