There's so much irrelevant, confusing info surrounding all of this. Bottom line it for me: are XC transactions really anonymous or can they be traced? I'm not interested in future promises, I'm asking about right now, this minute.
Monero is the best coin for anonymous transactions currently. It uses ring signatures and has been out for a couple months now. Darksend has also been functioning for months but it is not as sophisticated.
XC at launch had a central mixing node that is basically the same as a coin mixer site except you just connect right to the mixer from your wallet (very unsophisticated, requires trusting the dev). I believe it's currently disabled. That is probably what they were using for yesterday's test release. I think there is some misinformation that it was using "xnodes".
As a commenter said above, it is primarily the fact that loljosh developed the coin which makes me suspect that bold claims of coming up with this new xnode software are lies from atcsecure.
