There’s so many different programs these days that allow you to mine different crypto currencies from your PC.
So far as I write this, these are my two favorites.
MinerGate is a mining pool created by a group of cryptocoin enthusiasts.
It is the first pool which provides service for merged mining. This means that while mining on our pool you can mine different coins simultaniously without decrease of hashrate for major coin. (I really like this, they also have a phone app that lets you mine from your cell phone)
NiceHash is hashing power marketplace where you can mine altcoins and get paid in bitcoins or you can buy hashing power from other miners (cloud mining)
AntPool is an efficient digital currency pool and open for users all around the world, AntPool support mining of Bitcoin, Litecoin, Ethereum and support payment method. (Does a browser based mining)
P2Pool is a decentralized Bitcoin mining pool that works by creating a peer-to-peer network of miner nodes.
