I'm not very familiar with BTC mining, so I'm helping out an old buddy to consult the mining pros. The guy is planning to set up a mining farm in Equatorial Guinea. He’s thinking of building a water-cooled setup, with an average electricity cost of $0.03 per kWh. The mining rigs he’s planning to purchase are the Whatsminer M63+, with 442 TH/s hash rate and 7,293W power consumption. The daily guaranteed electricity supply is 1 million kWh, or 40,000 kWh per hour, with a self-built substation. He wants to ask the pros: if the 1 million kWh is fully utilized, how many M63+ rigs would be needed to max it out? What would the investment in machines roughly cost? And how much Bitcoin could be mined daily? If there are any experts who know more, he’d also like to ask: if the local chief becomes a shareholder, what are the key things to look into? Thanks in advance.
