I never sell anything.  My USB ASICminer Block Erupter's are now an art piece sitting on a shelf in my office.  It makes for great conversation.



My Bitmain USB miners are actually still in use as lottery miners.

I also have the a few USB scrypt miners (circular gridseed miners) that I need to dust off.  If I'm not mistaken, I may also have a stick USB scrypt miner.
