nicehash 1M cnr only need 0.0054btc/day
people mine kva use card cost more than buy nicehash 10X
you can check it on nicehash,rx470 4g card speed is 950H on cnr,and mine ETH one card have 30M hash,you can see "what to mine" To calculate

It seems like renting out your card to NiceHash Cryptonight isn't the most profitable option. Therefore, there's an inverse relationship to buying Cryptonight power off nicehash - so it is a good option to obtain KVA if you believe in it. KVA miners are mining KVA, not selling their hash power to Nicehash, so I really don't see how NiceHash is in any way exploitative. These markets are currently super low volume and volatile, and I would expect the prices to balance out over time. They are already over 0.00100BTC per MH per day, and if more people start using NiceHash to mine KVA, that will actually stabilize and push the prices further up!

I don't see how one can say it's 10X more expensive to mine KVA using RX 580 when you don't know 1. the price of KVA (not on any exchanges), 2. the electricity costs one is paying (region dependent), and 3. the amount they paid for the card - if that's even included in the calculation.
I think nicehash is good for KVA because it's allowing for people to buy the coin without needing the necessary set-up needed for mining. It lowers the barrier of entry. Once KVA gets on an exchange, the NiceHash Cryptonight costs should adjust accordingly. As a last note, the difficulty has been pretty low since launch - so I don't see this to be such a big issue for KVA miners right now. Sure, as a miner you're earning
a bit less than you would without NiceHash. But NiceHash is allowing for a greater distribution for the coin, thereby strengthening the market, benefiting all holders.
I think the laissez faire approach is more appropriate for this situation, as KVA's primary focus is not to bring the early bird miners as much profit as it could - but to put out a valuable new tech. The block reward will stay at what it's at now for another four years, and there's a lot more miners to come once this early period of an uncertain market is over.
