I think I get what you mean now, couldn't understand before with your broken english - that you can mine ETH on nicehash and get 10x more KVA than by straight mining it by buying Cryptonight hashpower with the profits from selling ETH hashpower. Not sure how accurate that 10x figure is because nobody ever posted the math behind it, but even if it is so, I don't see how that at all serves as an argument against a NiceHash compatible algo. The market will balance out over time, especially once the project starts getting a little bit more attention.

If the project changes algo and grows big enough... then nicehash could add its algorithm anyway.  And it's not like the current hash rate of ~5MH/sec is over-inflated or unfair to miners. It's minuscule.
