I prefer to collaborate exclusively with large mining pools, even if it sometimes reduces my profits (I have had negative experiences with scammers offering low fees). Via is one of those pools. Here you can mine Bitcoin, Litecoin, Ethereum, Dash, and many other cryptocurrencies. Ethereum (along with Classic) and Monero can be mined on graphics cards, while the others require ASICs. The rewards depend on the chosen model: there are PPS+, PPLNS, and solo. The fees are 4%, 2%, and 1% respectively. The conditions suit me perfectly, so I have no complaints.
