So I have had my Gridseed (5 chips) for about a week now, and still couldn't mine any Bitcoin, only Scrypt.

I am currently only able to mine with minerd, using Scrypt, and I am on a Mac. I tried to mine Bitcoin using cgminer, bfgminer, minerd (versions from MacMiner and others on the internet), tried to compile, nothings seems to work.


  • With cgminer I can see the hashrate (~11Gh/s) but no share is accepted.
  • With bfgminer it just wont recognize the grid
  • With minerd it keeps trying and trying, and does nothing.

Looks like cgminer is my best shot, but no share is accepted.

I tried on a Windows VM (virtualbox), same outcome! I have looked all over the internet (Gridseed-Help, Cryptomining-blog, GridSeed-Guide on BitcoinTalk, and off course Mac-Mining-Guide)

Does anyone have any input on here?

So, I'm not much of a miner myself, so please take this with a grain of salt.

When I plug in your numbers into a mining calculator, 11Gh/s resolve to earnings of just below 0.001 btc per month. This corresponds e.g. to the minimal "Send threshold" you can set on Slush pool. It's worth is less than $0.5 (for the whole month), where you probably pay a few cents per hour in electricity.

On another help page Slush pool states "Permanently Low or Offline state of your worker can be caused by weak worker whose hash rate is below 10 Gh/s. We recommend to switch off monitoring for such workers."

I suspect that your hashrate may be so low, that pools don't serve shares at a level where you can succeed, but perhaps you can find out more if you specifically research corresponding to that line of thought.

    Hi @Murch, but even with low speed, do you believe it would not show any accepted/rejected shares? Tks for the reply btw.

    Maybe you could add some log output from cgminer to your question, then people that know more about it than I should be able to give a better answer.
