About this site

Product information and ordering

Product specifications, pricing, program terms (including Heatoshi Now), and availability described on this site are subject to change. Orders are placed through our secure hosted checkout and ship within the United States; we'll communicate your shipping timeline after purchase. Joining an email list does not create an order, a reservation fee, or any obligation on either side — it signs you up for updates.

Heatoshi Now reservations: a $99 reservation fee secures a numbered place in line for the Heatoshi Now program, expected to launch in 2027. Reservations are fulfilled in the order they are placed. The reservation fee is non-refundable and is separate from program pricing, which will be announced at launch. A reservation is not a purchase of a unit and does not guarantee program pricing or terms.

Earnings estimates are not guarantees

Heatoshi earns Bitcoin through proof-of-work computation. Actual earnings depend on Bitcoin's price, network difficulty and hashrate, your electricity rate, and how much you run the unit — all of which change over time. Figures shown by the ROI calculator and elsewhere on this site are estimates based on current network conditions and are provided for illustration only. They are not a promise of future earnings, income, or investment return, and nothing on this site is financial, investment, or tax advice.

Limitation of liability

This site and its content are provided "as is," without warranties of any kind. To the maximum extent permitted by law, Promethean Innovations, Inc. is not liable for damages arising from your use of this site or reliance on its information.
