I have fast unreleased mod for z-cash 14% faster than the opensource kernel by dj-ezo

In 24hours I will release a new mod with 0.1BTC buy in and 2% fee. The algo is very profitable with my modded kernel.
EWBF already gives a 30% and it has a 1 or 2% dev fee while mining. You are going to have to do better than that SP.
