Im mining Sumokoin, and its being doing great. Its not a scam, its one of the best cryptocurrency out there.

SUMOKOIN is created with a high level of privacy in mind, setting Ring Confidential Transactions (RingCT) with minimum ringsize (mixin) of 12 to conceal sources/amounts transferred and make it high resistance to blockchain analysis
Untraceable
SUMOKOIN is untraceable; sending and receiving addresses are encrypted, transacted amounts are obfuscated by default. Transactions on the SUMOKOIN blockchain cannot be linked to a particular user or real-world identity.

Decentralized
SUMOKOIN follows Satoshi Nakamoto's vision of decentralized, trustless cryptocurrency, i.e. a secure digital cash operated by a network of users. Transactions are confirmed by distributed consensus, and then recorded on the blockchain immutably. Third-parties do not need to be trusted to keep your SUMOKOIN safe.
Fungible
SUMOKOIN is truly fungible, thanks to built-in privacy features. Just like cash, all SUMOKOIN are equal, changeable. It is extremely unlikely that coin will ever be blacklisted by any party due to its association in previous transactions.
