The miner fee is not an issue since your net income should increase by at least 20% compared to public lyra2z miners  currently available.
The Fee amount will decrease with each new Release relative to comunity interest, it's just for helping us keep the development live and to contenue Optimizing zFastminer and other Algos too.
When you find great deal on product that is 20%~30% lower then the current market price, are you gonna cancel your order just because the retailer will not say to you what his commission rate on the purchase - do you?

We continue our work on this project and we will share with you any further improvement that we can achieve...
At this stage, the fee will help us to continue to support the improvement of the software, but even at this moment, Zcoin is the most profitable coin for mining with NVIDIA cards that we mentioned with our zFastminer...

Thanks' to everyone who started mining with our zFastminer software.
Follow this thread for updates about further improvements very soon ...

Hope you also will join our zFastminer software and enjoy it...

Best Regards,
zFastminer team.
