How much is the withdrawal fee, when I want to pay out my earned BTC to my wallet?
And do somebody use guiminer-scrypt v.0.04 and know how and where I can add a backup pool?
You just add strings at the end of the "Extra Flags" field like so:
--no-submit-stale -o stratum+tcp://stratum01.hashco.ws:8888 -u USERNAME -p PASSWORD -o stratum+tcp://stratum.give-me-ltc.com:3333 -u USERNAME -p PASSWORD
