I was mining BTG for at least 4hours... and all my credit disappearead ....
I don't know if I did something wrong.. but mining ZCL was normal... I just tryed to change the command line:
mine.bat -
ZCL: bminer -uri stratum://user.worker:pwWorker@zcl.suprnova.cc:4042 (WORKING)
BTG: bminer -uri stratum://user.worker:pwWorker@btg.suprnova.cc:8816

I deleted the text inside mine.bat with "@echo off"etc... and used just the command above.
I really wanna mine BTG with this miner... can someone help me plz?
if thats the command line your using you have to use your suprnova username in there... eg. -uri stratum://pietroow.worker1@btg.suprnova.cc:8816
otherwise it should work.
