Personally I'm very interested on someone's technical analysis of the anon tech in XC. I mean Darkcoin is constantly criticised due to it's technical failings over the past few months. But the lack of criticism of XC leads me to believe that it's might fall in to one of these two categories:
1) That the anon tech is actually solid.
or
2) That the distribution and such was so bad that people don't even think it's worth analysing the tech and thus we don't actually know whether it works well or not.
Just the one above point from darkota, strongly smacks it technical merits, and you can be sure that intelligence agencies are flooding this space. If not, they should be named "ignorant" agencies. If you are going to invest into multiple cryptos, I would break the investment down % wise by what technically is on top, but also on just public perception The latter can create a snowball effect from a pump but usually won't last. E.g. Dogy.
