In crypto mining profitability of operations heavily depends on difficulty of mining. Difficulty rises and share for each mining machine drops. Share drop affected by new mining farms joining mining and new more effective equipment availability for purchase. Mining operators have to continuously invest in new equipment, approx. every 2 years.
So there’re plenty of obsolete miners available for sale on Alibaba.com. You can by Antminer S9 13.5T for 150$. When it was issued to market 2 years ago people paid 2000$+, but it was bitcoin bubble. Anyway now Antminer S15 28T costs 1035$ and it is “sold out”.
What if we could use S9 like S15 without purchasing it? Is it possible?
What is required:
2) 15 miners (prepared for immersion cooling)
3) custom firmware
4) The test with standard PSU 1400W shows 15T, however test with PSU 2100W will bring hashing power to 20-24T.
By 90% will drop cost for cooling you miners
No dust, no shutdown for cleaning
3x more miners in the same room
Savings on investment in miners
