What I've noticed though that no anon coins are used there. It's just Bitcoin (and sometimes Litecoin). No Dark XC Cloak Monero and so on.
It proves my belief that all anon coins are more or less marketing gimmicks with no real world usage, and very unclear perspectives.
What it proves is that these projects are newer and smaller than Bitcoin or Litecoin, and some important projects i this area aren't even released yet. If there is still no usage several years in the future you will turn out to be correct, but it is by far premature to make that pronouncement now. It is very similar to looking at Bitcoin around the time of the 10K BTC pizzas or even earlier and saying people are just using fiat so Bitcoin is more or less a marketing gimmick with no real world usage, and very unclear perspective.
