The Whatsminer M31S+ mines Bitcoin & Bitcoin Cash and other cryptocurrencies that use the SHA-256 algorithm, so you can point it at whichever supported coin or pool suits your strategy.

ASIC miners are algorithm-specific, so it cannot switch to coins on other algorithms — if you want a different coin, browse the full range or ask our team what fits.

We accept UK bank transfer and selected stablecoin payments such as USDT or USDC. We do not take cash, and card payments are generally not accepted on high-value hardware.

For your security we never change bank details by email — if anything looks unusual, stop and call us before sending funds.

In-stock machines are dispatched within 24–48 business hours of cleared payment, and UK delivery typically takes 2–5 business days on a tracked service.

We can also ship straight to a hosting facility, or arrange collection by appointment once funds have cleared.

Yes — on direct orders the price you see is the price you pay. Delivery, import duties and applicable taxes are handled by us.

That means no surprise courier invoices or customs paperwork after checkout.

Check your power, heat and noise first: the Whatsminer M31S+ draws 3192W and uses Air cooling, so it may need a dedicated circuit and proper ventilation rather than a standard socket.

If home is not practical, hosting gives you the same machine on wholesale power with heat and noise handled for you.

Yes. You own the miner, we run it in a specialist facility with 96–99% uptime targets, and rewards go straight from the pool to your own wallet — we never hold your coins.

Hosting is typically a 12-month term with the first month paid upfront — see how hosting works, or ask about Mine Before It Arrives (£40 + VAT) to start earning while your Whatsminer M31S+ is still in transit.

A 12-month manufacturer warranty as standard. We log serial numbers, photograph key components and keep your test reports on file, which makes any claim far smoother.

Overclocking, unauthorised firmware, unsuitable power supplies or third-party dismantling voids cover — talk to us before modifying anything.

Yes — diagnostics and repairs are in-house services covering hashboards, PSUs, fans and firmware, with a £150 + VAT diagnosis fee deducted from your final invoice if we complete the repair.

Repair customers get a dashboard showing progress, photos and inspection records.

We have mined since 2011 and sell only brand-new, genuine hardware — every machine is inspected, serial-logged and test-run on your own pool before dispatch.

Sales, hosting, repairs and honest advice under one roof — talk to the team before you order and you will never buy blind.
