SUPER is very under valued now. It's market cap is about 1/20 of that of XC, and 1/200 of that Darkcoin. These 3 coins have anon features in tests, none in the main network now (correct me if I am wrong - DRK has a main network "candidate" build).
SUPER may have anon feature in the real network in 2 weeks, not sure when XC will have. I think SUPER needs more promo, so people know this nice little hidden treasure there
You are right, the only thing that the other coins have that SUPER lacks is big promotion
supercoin has real things, not just illusions like many other coins. With promotion, it will be much higher.
