ETCHash · air-cooled

No payback while the machine runs at a loss
Revenue assumes a 1% pool fee at the current ETC price and network difficulty, with the machine running continuously. Payback needs a hardware cost, which we do not publish because we have no verified retailer feed — add your own purchase price in the calculator.

Data provenance
Community-reported hashrate at stock settings. Last verified 2026-07-31.
Note: GPU hashrate varies substantially with memory tuning, power limit and driver version. Treat this as a mid-range figure, not a guaranteed one.
Noise, dimensions, weight and warranty are not listed because we have not verified them for this machine. We would rather leave a field empty than publish a figure you cannot check.

HB 639 gives residents a self-custody right, exempts miners and validators from money-transmitter licensing, and creates a dedicated superior-court docket for blockchain disputes.
TeraWulf leased its Justified Data campus in Hawesville, Kentucky to Anthropic for two decades, in a deal expected to generate roughly $19 billion in revenue — a figure larger than the bitcoin miner's own market value going into the announcement.
Hyperscale Data signed a Master Services Agreement on 24 June with an unnamed California-based neocloud, committing 20 megawatts of AI compute at its Michigan campus over ten years with a headline value above $1.2 billion. Options carry the deal to $3 billion. The mining operation the site had been running is winding down.
