I started to get into the details of XSPEC, and the more I know about it the more I am amazed about the comprehensiveness and completeness of it's privacy features, even without stealth staking. I now truly can say and defend that it's the best privacy coin out there, even surpassing Monero. Here is the gist:
1. Sender anonymity : Ring Signatures
2. Receiver anonymity : Dual Key Stealth Address
3. Transaction privacy : Automatic Transaction Splitting
4. IP level protection : TOR based
5. Quantum resistant : Proof of Stake
6. Resistant against compromising of key individuals : identities of core team unknown
Most advanced privacy coins offer features 1 and 2, using various methods. A smaller number add either one or two of the features 3, 4 and 5. But AFAIK, none adds all 3. (Deeponion fans might claim they add all 3 features, which could be true, but they also include Proof-of-Work which introduces several vulnerabilities). But no other privacy coin - NONE WHATSOEVER - has an unknown development team. Think about it: should a powerful government want to crack down on Monero or DeepOnion, for instance, they could infiltrate or even eliminate and replace the development team, since the project members are publicly known. XSPEC is protected even against such personal attacks.
Really amazing stuff, if you ask me.
