Doing some changes with my farm, I have 4-Z15 320J that I have hosted with @AdamMoyers that have been running great little over a year. Looking to sell each for $850 will come with a Bitmain power supply also.
I also have some LT5 Pros, CK6,K7, S19Jpros ,HS3, JasMiners, available too. Message for more info
