That would be a contentious claim. XC's anonymising system is only partially implemented - but what's implemented (the mixing tech) is working as intended. Nonetheless without greater transaction volume and/or the multi-path technology (which is the novel and central piece of tech this coin is bringing to the marketplace) it's still possible to track transactions by matching amounts on the blockchain. So I'd say no, it's not the time to declare that XC is anonymous. However it's already succeeded in implementing a level of anonymity that certain coins are still struggling to attain.
