I'm trying to mine on the middlecoin pool using the following command:

cgminer --scrypt -o stratum+tcp://middlecoin.com:3333 -u 1C7Ubg5VxvJyXYBT6neNVFgUVdgq1Kiy72 -p asdf

and I do get the screen below, but I'm not seeing my bitcoin address appear on: http://www.middlecoin.com/allusers.html (and I've waited a couple of hours)

I think your main issue is that your hash rate (speed, essentially) is extremely low. You're averaging about 3Kh/s. For comparison, most mid-range miners are running around 5-600Kh/s, and if you run a mining tool on your Google Nexus 7 tablet or Nexus 4 cell phone you can get around 2Kh/s which is very close to what you're getting.

I can't really help you with this without knowing what kind of hardware you have that you're trying to run this on, but take your video card model and search google for "cgminer settings" with your model after that to see what you can find.

  • Hi - thanks for replying. I did use different cgminer settings and the hashrate bumped up to ~14 kH/s and I started seeing Accepts after a couple of more hours. I tried my hand at solo mining for a bit, but was completely uncertain whether it was actually working or not (different Q on BC.SE) - any thoughts on that? – siliconpi Feb 4 '14 at 10:35
  • The reason why I didnt see my results on the middlecoin webpage was probably related to a server issue at their end. – siliconpi Feb 4 '14 at 15:58
