if i had 10k and 2 cent power i would order a s19 direct from bitmain for 7k. they have them on sale now.

i would hold the 3k hoping that i may get a cheaper unit in three or four months. but i would be mining in under two weeks with the s19 i buy for the 7 k.

that unit will burn 80 kwatts a day in your case $1.60 a day.
