no i didnt see anything mentioning that, so what do i need to change in my bat ?
its a part of your password.
so with scrypt and a manual difficulty setting your password would look like this:
d=5,scrypt
password for payout into BTC while mining scrypt with no custom difficulty:
c=BTC,scrypt
password for payout to BTC on scrypt with normalization for profitability:
c=BTC,scrypt=1.0
as well as options for any other algos in that rotation, or combinations of them.
The information is on the main page, and the links for setting up multi algo, etc.
