What is Mintcoin (MINT)

Mintcoin was released in Feb, 2014. Coins which use proof of work consume a lot of electricity and may be harmful to the environment. Mintcoin therefore uses proof of stake. Unlike Bitcoin, there is no max supply of coins. New blocks (which contain a batch of transactions) are generated every 30 seconds. Holding onto Mintcoins gives you a 5% interest every year.
