Mintcoin is an innovative secure power-saving hybrid PoW/PoS cryptocurrency. It used faster PoW-mining during first 5 weeks of its existence for amassing initial amount of coins. After that (on February the 6th, 2014) it has almost entirely switched to a more passive PoS-mining which doesn't use nearly as much electricity.

The annual interest rate during PoS-mining is variable. It equals 20% during the first year and will drop 5% a year after that until it reaches 5% four years later.

As the cryptocurrency switched to PoS-mining 5 weeks after its launch the reward for PoW-mining has dropped as low as possible. The bulk of coins will be generated in PoS-mode by the merit of which this cryptocurrency saves a lot of electricity.

The total amount of coins to be mined is 70 billions. PoS-mining starts after 20 days of storing coins in a wallet. With PoS taken into account, this cryptocurrency is more resistant to 51% attack.

As miners users will earn large number of coins during early stages of MintCoin's existence. And later, as investors, they will get a huge return from their long-term coin deposits.

MintCoin is also meant to be widely distributed throughout the world as it is available in large numbers.
