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.
monero is at a point where it has a very large community with some 200+ individuals contributing code. It would be virtually impossible at this point to track down the entire "team" and prevent somebody to fork the project and carry on. It doesn't even matter now who started it. And generally that is the best approach because to be honest tracking an individual nowadays is pretty easy. Real anonymity is very hard to achieve these days and only through very illegal means. Even then it's a matter of how hard the said government is trying to get you and if they are willing to play dirty or not
FYI there are other coins with anonymous devs (see skycoin) and it's not generally perceived as an advantage.
