Buy It Here. Run It in Iowa.
At the U.S. home electricity average (~$0.17/kWh), most modern ASICs lose money. Hosted at our Iowa facilities on industrial power, the same machine mines at a margin. We rack it, monitor it around the clock, and fix it on site while you watch the dashboard. Compare both scenarios for this model before you decide where it plugs in.
