Hi all 👋,

I’ve been offered the chance to buy a small Bitcoin mining setup from a trusted friend, and I’d really appreciate your experienced eyes before making a decision.

The setup includes:

- 6 complete Bitmain AntMiner S9 units

- 2 additional modules reconfigured for liquid cooling

- Full infrastructure shown in a video (link below) covering ASICs, power layout, ventilation, and more

Context that matters:

- Location: Mexican Caribbean — where electricity is both very expensive and highly unstable

- The farm ran successfully for 2 years but has been idle for 4–5 years

- My friend is offering it for 20,000 MXN, which includes initial setup support and maintenance guidance

I’m still new to mining at this scale, so I’d love your input on:

👉 What should I look for in the video? (e.g., signs of wear, dust buildup, corrosion, cable quality?)

👉 Given today’s hashrate, difficulty, and BTC price — is this hardware even viable?

👉 With high electricity costs and grid instability, could this ever break even?

👉 Are liquid-cooled S9s a red flag or a clever hack?

👉 Any critical questions I should ask my friend before saying yes?
