VeriCoin is a new (since May 2014) cryptocurrency, which utilises Proof-of-Stake to verify transactions. This model means, instead of mining, you earn interest on the coins in your wallet – just by having your wallet open! So without high-intensity power-hungry mining, it's also better for the environment than BitCoin!
VeriCoin is also the first altcoin to be accepted by merchants, ANYWHERE BITCOIN IS ACCEPTED, via VeriBit!
