I have several USB miners for sale that I cannot use anymore because I need one of my USB-hubs for another project.
Take into consideration that I am in Europe and shipping to overseas might not be so cheap.
Please consider that recent SHA-Miningsticks like the Gekko cost around 40-50$ for 8-20 GH/s!
Anyway, all of them are working and I will add a free Antminer U1 (2 GH/s) on top of each.
4x red Bitfury +/- 2.6 GH/s
1x Bitfury BFx2 +/- 4 GH/s
1x Bi*fury +/- 5 GH/s
2x Nanofury NF2 +/- 5-6 GH/s
1x Nanofury NF6 +/- 15-16 GH/s
They all require a little bit of airflow in order to hash at their maximum speed. I obviously played around with them, but to be honest, I never overclocked any of them, because it was simply not worth it. Run them at standard settings in BFGminer or CGMiner and they are set and forget.
They might be worth a shot for mining SHA-Altcoins or even as a lottery device when going solo-mining.
I intend to donate the proceeds to the local animal shelter, so make me a PM with your offers please and don't be stingy.
keep on hashing,
