I have a basic knowledge about an idea of cryptocurriencies. Recently I have read articles about Zcash. Rumours has it that it's the most profitable cryptocurrency on the scene. Me and my co-worker want to mine Zcash. I know that we need high hashing power. I was thinking about cluster of high-end graphical cards. With our budget we can afford more or less 15 GPU's. My very basic calculation says that we should have something around 300.000 MH/s. Will it be profitable and feasible assuming we want perform solo mining? Is there a good piece of software for Zcash solo mining?
Profitability will all depend on the cards you buy, your electricity cost, and your overclocking configurations. I haven’t mined zcash in a few weeks, but when I was mining I was getting about $12ish dollars a day with 3 Nvidia 1070 Ti’s. My hash power was about 1560 sols/s(zcash’s version of a h/s). Each card was running at 85% power and getting around 520 sols/s.
I would say at 15 cards, and the hashing power you mentioned, you should be more than profitable. If you want to get a good idea of how much you will make, checkout whattomine.com, it’s a great resource for measuring profitability.
