[WTS] Bitmain S21 Hyd, 335TH, lightly used, EU shipping

Did the math on power costs at my facility: 0.041 USD/kWh, rigs at 17 J/TH, current network difficulty. Payback at $95k BTC is roughly 14 months excluding heat reuse. Heat reuse to greenhouses cuts that to ~10. Happy to share the spreadsheet.

Sideways for me.

This.

I've been running a node since 2020 and the difference in propagation latency this year is night and day. Pulling logs from three peers across EU/US/APAC, median block-relay is down ~38% since the last compact-block tweak. If anyone wants the raw data I can drop a CSV.

Been saying this for months.

Tested it — confirmed.

Any benchmarks?

Nicht überzeugt.
