Hi Guys,
Looking for recommendations what kind of 2nd hand rigs would you be using if i have shophouses with maximum electricity capacity of 70,000 watts.
We have relatively cheap electricity and looking for fastest roi.
Our monthly operating costs is about:
$600-$800/month rental
internet is about $50/mth
If your electricity bill is free and stable for a long time. I recommend Antminer S9j (14.5t 1350w). Each machine can earn you around $3 per day. s9j is about $200 and you only need 68 days to get your money back. In addition, there is an s9j in my mine that has been used for more than 4 years. He still has no problems and continues to work. I think it will be fine for him to work for another two years.
