Uniquely Zcash is mined like other crypto-currencies, but like everything now suffers from increased complexity and low cost, I personally am also mining but do not sell what I advise, because selling now for a song you simply work for electricity and lower it low market, but if you wait at least to the level at which it was raised (800), you can already think about selling, and the funds will be a heap that is more useful and the mining will be profitable. All profit and patience!
Mining Zcash using the GPU is not profitable to date, because ASIC appeared, which mining coins Zcash is much more productive than the GPU. I believe that the more perspective mining coin, which is the most profitable to date, is to sell it and buy Zcash, so you will get a larger amount of Zcash than if mining Zcash.
