NXT is not an anonymous currency as far as I know. I recently researched into NXT a little and I'm not sure what value it adds. It seems to be the selling points are original code that isn't copied from Bitcoin and proof of stake. I'm not sure I understand why its price is rising recently though. Maybe there's something I'm missing. In any case, it is not a direct competitor to XC in the anon space so they are quite different. If you're asking will XC exceed NXT's market cap, it depends on whether the dev is legit and the future releases don't have critical failures. I feel the existence of this thread is also hurting the coin. They should not have gone to a self moderated topic because it has split the community and shielded a lot of constructive criticism.
