Our mining efficiency is measured in Kh/s because we use Scrypt crypto-algorithm as a basis but as a matter of fact we mine crypto-currencies using different modern algorithms (Scrypt, Scrypt-N, X11, X13, Keccak etc.) that’s why actual mining efficiency of exact currency can differ from other currencies.

It’s incongruously to compare our efficiency with Bitcoin mining, because it’s already measured in Th/s. It’s so because Bitcoin is using outdated SHA-256 algorithm which allows faster hash decrypting. We’re not mining Bitcoins directly because difficulty of such mining grows constantly and unpredictably and yields become low really fast and that’s why it’s really hard even to pay off the cost of hardware with such yields.
