I can buy Antminer S9 13.5Th/s for 350USD. Is that a good price? I have heard that it is little bit noisy, so in my bedroom it is not the best place for it right?
What ?350USD?
In China, the S9i 14T with power supply has been used for less than half a year, and the price is not more than 1,300 yuan, about 185 USD.
