Nasdacoin is an encrypted and decentralized Virtual Currency, open source, point-to-point, developed with the scrypt algorithm in the POW/POS Hybrid format that allows people with an entrepreneurial and passionate profile about the financial and technology market to store and invest their wealth in a safe currency not controlled by the government and even gain a substantial investment interest.
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.
