Unless something crazy happens, the next ASIC miner I buy will probably be from sidehack. Although with the price of BTC down, he is sitting on a sizable number of 2Pac miners that is slowing him down a bit. I'm hoping that he can get the 16nm usb stick miners done before too long, and then get to the 16nm pod miner he's been wanting to do for a while.
When I look at the prices of new ASIC miners and the value of any of the coins they mine, ROI is usually one or more years away with the current network hashrates and difficulty, and we all know how that works out.
Are you serious about buying USB based stick miners at this point in time? Haven't those been long obsolete even with free electricity? As far as i know they earn a few cents per month which really isn't worth it so you will have to be playing solo-mining lottery?
I'm interested to learn more about your "plan" for USB stick miners.
the 16nm pod miner is what he really wants.
