Novacoin is a hybrid Proof of work (POW) / Proof of stake (POS) decentralized peer-to-peer cryptocurrency.The Proof of Work part of Novacoin is based on the Scrypt hashing algorithm. Proof of Stake contributes to the coins energy efficiency, as there is no need for nodes to contribute mining power to part of the money creation process. As of now, Novacoin is set to be capped at 2 billion coins. However Novacoin stated that the cap limit may be lifted if the situation requires it. It looks very much like a variation of Sunny King Peercoin.
MaxiMineCoin allows token holders to stake their tokens in return for hashing power assigned to mine a cryptocurrency of their choice. MaxiMine will allow its users to freely switch between different tokens and mining pools to allow them to maximize their profits and returns. MaxiMine will also be one of the first few to receive state of the art and early releases of advanced mining rigs such as the Bitmain ASIC for Ethereum (as seen on CNBC). MXM tokens provide the opportunity to be part of partnerships most outsiders can never attain.
