If you want to buy and hold a coin Zcash I don't think it's a good choice, because the Zcash coin launch price is very high, but it's good if you are a miner and get zcash coins for free and continue or direct sales after receiving zcash coins.
Mining Zcash is not profitable at this price at all! Investing in it can probably be profitable, it spiked nice few times, and I dont think this price is real! But if you look at % from top 20 coins I think that DASH is currently most underpriced coin cos it fell most in % from ath!
