Built for Solo Mining
Solo mining means mining independently — no pool, no shared rewards. One lucky hash wins the entire block reward. Low-power miners like this one are perfect for solo mining: the electricity cost is negligible, so you can run 24/7 as a perpetual lottery ticket.
Every hash has an equal chance. Every hash counts.

Heating offset estimates the value of heat replacing an electric space heater during heating season (~6 months/year in Canada). Actual savings depend on your heating setup and climate.
Solo Mining Estimate
Solo mining is a lottery. There is no guarantee of finding a block. These estimates are based on current network difficulty and your hashrate. Every hash has an equal chance.

Frequently Asked Questions
Is the StealthMiner profitable?
At $0.07/kWh, the StealthMiner currently operates at a daily loss of $0.00. However, profitability can improve with lower electricity rates or rising BTC prices. If used as a space heater, the heating offset may make it economically viable.
Can I mine Bitcoin at home with the StealthMiner?
Yes, the StealthMiner scores 70/100 for home mining viability. It produces 28 dB of noise and draws 18W. It is suitable for home environments with appropriate placement considerations.
Can the StealthMiner heat my home?
The StealthMiner outputs approximately 61.4 BTU/hr of heat. For reference, a typical space heater produces 5,000-5,500 BTU/hr. All electrical energy consumed by the miner is converted to heat, making it 100% efficient as a heater. D-Central offers Bitcoin Space Heater builds designed specifically for home heating integration.
What power supply does the StealthMiner need?
The StealthMiner draws 18W of power. You need a power supply rated for at least 20W with appropriate voltage (5V DC (barrel jack 5.5x2.1mm)). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect your investment.
