MicroBT WhatsMiner M70
Latest Generation Hardware
This is a newer generation of mining hardware using recent ASIC chip technology. Compare efficiency, hashrate, and power draw against older generations before choosing a deployment plan.
Lower J/TH means lower electricity cost per unit of hashrate. Compare efficiency alongside purchase cost, noise, voltage, firmware support, and current network difficulty.
Professional-Grade Miner
This miner draws 3,422W and produces 75 dB of noise — it is designed for dedicated mining environments, not living spaces. Professional-grade miners deliver the highest hashrate and revenue per unit but require proper infrastructure: a 240V circuit, adequate ventilation or exhaust ducting, and a space where noise is not a concern (garage, basement, warehouse, or outdoor enclosure).
For home miners looking for a quieter alternative, consider our Bitcoin Space Heater builds or explore open-source miners like the Bitaxe that are purpose-built for residential environments.
Heater-Class Miner
At 3,422W, this miner outputs approximately 11676 BTU/hr of heat — equivalent to a standard electric space heater. Every watt consumed by an ASIC miner is converted to heat with 100% efficiency, making it a space heater that also mines Bitcoin.
During heating season, miner heat can offset part of the heat a room would otherwise need from another electric heater. The economics depend on your electricity rate, room heat demand, BTC price, network difficulty, and noise constraints.

| Period | Revenue | Electricity Cost | Profit |
|---|---|---|---|
| Daily | $6.43 | $5.75 | $0.68 |
| Weekly | $44.98 | $40.24 | $4.74 |
| Monthly | $192.78 | $172.47 | $20.31 |
| Yearly | $2,345.50 | $2,098.37 | $247.13 |
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.
