Thanks for your response.
So it sounds like whatever USB based Asic days gone for good?
Any suggestion other than Chinese Antminers?
I'd definitely refuse those because there was already countable speculations that they had untrustworthy firmware codes.
the only usb asic stick with a modern chip is designed to mine LTC not BTC
There is no small quiet BTC miner with a modern chip.
A modified s-9 using 1 board vs 3 boards can be made if you have an old firmware model
this uses about 385 watts to hash 3550gh
