The nist5 algo is used in other coins as well.. Zpool.ca is currently paying 0.01602 a ghash of NIST5 with 6 coins in the pool. (19 GHASH net hashrate)
current profit for the gtx 1070 with the unreleased sp-mod #1 is (53MHASH)
0.01602 * 0.053 * 3269 = $2,77557714 per day
but if you mine the coins yourself and exchange them you don't loose 30%. (zpool's hidden fee)
And where can I get it or download it?
It's not done yet. I think I will take the usual 0.05btc + 2% fee. I am hitting 55MHASH now..
