https://nicehash.com/software/ CG and SGminer. They work on scrypt.
"to use sgminer for Scrypt-Adaptive-Nfactor add those settings in the conf file: "algorithm" : "adaptive-n-factor","nfactor" : "11","kernel" : "zuikkis"".
I do it, but conf file don`t work. I always use .bat. How add it.
For example sgminer --adaptive-n-factor -nfactor 11 -k zuikkis... not working.
Give me working settings for .bat. Thx.
