Some cryptocurrencies (like ETH) can't be mined with ASICs, due to large (2gb and rising) RAM requirements
Pure PoS cryptocurrencies cannot be mined by suchflex.
Then I was wrong, does suchflex also mine ETH then?
It's pretty easy to set up ETH mining yourself and pocket all the money, but that's probably not the audience this software is intended for (Windows users with access to "free" electricity).
