This listing is for 1 x pre-order January Bitmain Antminer 15G 3360w Miner. The unit does not include a power cord. Have less than 10 feedback. Cannot power up and test the unit within 48-hours of receipt. Are not familiar with ASIC mining hardware and have not mined previously. Live outside the US. I urge you to use a professional facility to host this unit, this unit. Creates noise and heat and most houses are not setup with the power requirements to handle such a device. You will need to vent this unit to the outside and not recycle the air, if not vented properly hash rate will decline rapidly. The unit will require a 220v 20 amp circuit. Please contact me first! Crypto currency mining is highly risky. The coin that you are mining can increase in difficulty reducing your profits dramatically as new miners are brought online. If you have questions on setup please contact me before purchasing the unit.
