Go to Bitcoin Merch ↗What it could earn
If you pool mine: Costs about $41/mo more than it earns at $0.15
Break-even power price: about $0.081/kWh
Above this price the power costs more than the pool estimate.
As a heater: the ≈$88/mo of power is heat you'd pay for anyway, so the pool estimate is your net: about $47/mo back
Only if it replaces an electric space heater you'd run anyway, and only while you need the heat. A heat pump or gas is usually cheaper per unit of heat.
Estimate. Changes with Bitcoin price and network difficulty. Uses BTC ≈ $80,382, network ≈ 1,026 EH/s and the seller-stated hashrate, minus a 2% pool fee and a 10% safety margin, rounded down. Updated Nov 5, 2026 1:47 AM ET. Solo vs pool

About the GekkoScience KBeast 50
The GekkoScience KBeast 50 is a plug-and-mine room heater miner built on GekkoScience's KBox platform, with an integrated 800 W power supply. Bitcoin Merch states up to 50 TH/s at 800 W at the wall, with efficiency down to about 13 J/TH when tuned, and High/Medium/Low presets you can edit.
Best for: Someone heating a room this winter who wants roughly Avalon Mini 3 / Heatbit Maxi class hashrate in one enclosed box, and is fine waiting for the shop's ship date.
Check before you buy
- Bitcoin Merch's listing says it ships in December 2026, so check the stock badge before you pay.
- Right now only Bitcoin Merch sells it among the shops we track.
- The 800 W PSU is built in (120 V or 240 V). No external power supply to buy.
- At 800 W it heats like a small space heater. Use a dedicated outlet; don't share a power strip with other big loads.
- Hashrate and heat depend on the power mode you pick. The figures above are the seller's, not our measurements.

How much heat does the GekkoScience KBeast 50 give off?
Almost all the electricity a miner uses comes out as heat, like an electric space heater. At full power that's about 800 W, or roughly 2,730 BTU per hour. How heater miners work.
Will the GekkoScience KBeast 50 pay for its electricity?
Usually not all of it, and nothing is guaranteed. Pointed at a mining pool, it earns small, steady amounts of bitcoin that can offset part of the power bill. How much depends on Bitcoin's price, the network's total hashrate and your electricity rate, and all three change. Pointed at solo mining, it's a lottery ticket for a whole block. Solo vs pool, explained.
