You got a great mining equipment. Your investment will definately pays of, especially when it comes to speed (1-2% per day vs 16 hours?) . I wonder what your electric bill is. I know it must be pretty high, but still it’s worth it. I knew about mining hardware, I know some of cab drivers and others having it as a second job. But it’s mostly an investment in my opinion and a great and profitable one. Wish you a great and successful mining!
