No use smart switching mining software to utilize you hash power based on what coin is "hot" at the moment. Nicehash does this a bit but a better way is to take something like awesome miner and switch in between multiple multi pools like nicehash, zpool. I use two only because minimum payouts are usually like 0.1 btc and if you have too many pools that might take a while. The concept is cool since if a new coin comes into fruition and people need blake2 like crazy in one hour that because really profitable to mine. Also ZEC, BTG are very miner friendly for mid term.
