how to set my own difficulty in cgminer? stratum+tcp://us.clevermining.com:3333 -u YOUR_BTC_ADDRESS -p anything d=128 ?? I got error to long command line
1. You probably don't need and don't want to use custom difficulty. For most miners it will work best with vardiff.
2. You should try: stratum+tcp://us.clevermining.com:3333 -u YOUR_BTC_ADDRESS -p "d=128"
