So how do these antminer usb sticks stack up to Bitfury yellowjackets? What are some key differences?
You might want to answer this, I want to buy in bulk.
I don't own any Furys but I do own ANTminer U1s, and I can say at 2Ghash they mine with zero hardware errors, and I've been seeing posts some people can run them at 2.2Ghash without doing the resistor mods, and at the current BTC exchange rate these ANTs are are more cost effective than any of the nanofury based miners.
The Yellowjacket Fury runs about $100 right now, the ANTminer U1 goes for about $70 each, so you are paying a $30 premium for a guaranteed 0.2Ghash higher mining rate... and to boot, from what I have seen in my rig whcih is a mix of Block Erupter USB and ANTminer U1 miners, the U1s use the same or slightly less electricity than the BEs, so the same USB hub configuration will run the ANTs vs BEs...
This is a no-brainer for me.
