Mining pools these days have Bitcoin as the main cryptocurrency being mined. This has been the trend ever since. The mining of Bitcoin is so popular that almost all mining pools mine it and other cryptocurrencies. This has been countered by the Nanopool. It is one of the few mining pools that mine other cryptocurrencies except Bitcoin. They have Ethereum as the main cryptocurrency they mine, this has not really affected it's popularity as Ethereum is also a popular cryptocurrency. The Nanopool is capable of supporting coins like Ethereum, Ethereum Classic, ZCash and others. They charge a standard fee of 1% and 2% for some coins like Ethereum due to its high charges for gas fee. It started operation in the year 2018 and is presently in charge of more than 30% hashrate.
Payments on this mining pool is made possible via the Pay Per Last N Shares (PPLNS) which is the most secured payment method. Mining has never been this easy, thanks to Nanopool !!
