X13?? just add more algo, it's nothing, you can make X15 or X17, it's no different than X11. Keys are features that improve the fundamentals of the coins, such as PoS superblock, PoW/PoS separation, true random etc, and maybe anonymous features.
If there become a crypto coin which is X11 algo and uses anonymous feature. We can implement it.
X11coin (XC)
Thank you i forwarded it to our dev. He will check.
But it looks to me at first sight not a very stable coin yet, see new fixes coming.
Edit: Our dev says it's only x11 coin with anonymous feature he aware of and he doesn't see the source codes of anonymous feature yet. As soon as they release the codes at github source. We can check to implement. The last 2 check in seem to have something, he needs to check later, other checkins have nothing there.
moreover, yesterday he compiled that coin, it does not seem to run well, he says it crashed his computer.
So we prefer to watch another similar x11 coin coming out, this one has a lot hype, he doubts how many real there. So let us know if you any X11 crypto we can check the codes of anonymous feature or anything you think we should have.
