Overview
MicroBT Whatsminer M21 (31TH/s) — Hardware Overview
Learn more about this ASIC miner, including its specifications, performance, energy consumption, and profitability.
The MicroBT Whatsminer M21 arrives like a precise instrument forged for the alchemy of SHA-256, offering a steady 31 TH/s while drawing about 1860 W f…rom the grid and achieving roughly 0.06 J/GH, a balance of brute hashing and economical energy draw that makes it attractive to solo hobbyists and professional rack operators alike; built-in power supply and robust thermal management simplify installation and lower the barrier to entry, while its ASIC architecture is tailored to mine Bitcoin and allied coins sharing the SHA-256 family-Bitcoin Cash, Bitcoin SV, Namecoin, Ecash, Fractal Bitcoin and Peercoin-so operators can pivot across chains as conditions dictate. In practical terms the M21 rewards careful site planning: reliable mains, ventilation, rack space and monitoring for temperature and uptime will protect hashing continuity and ROI, and using pooled mining, firmware updates and quality cooling will maximize long-term performance. To translate raw hashes into operational decisions, a comprehensive profit calculator that models your hashrate, current network difficulty, block rewards and pool fees alongside electricity consumption and local rates will produce daily, monthly and annual yield projections to help compare setups, optimize energy strategies and decide whether to scale, diversify coin targets, or focus on efficiency improvements that tilt marginal gains into consistent advantage.

Deep dive
MicroBT Whatsminer M21 — In Detail
MicroBT Whatsminer M21 (31TH/s) — a closer look at the hardware and how it performs.
The MicroBT WhatsMiner M21 is a purpose-built SHA-256 ASIC that produces a steady 31 TH/s while drawing roughly 1860 W and delivering about 0.06 J/GH,… positioning it as a high-throughput, energy-aware choice for mining Bitcoin and SHA-256 siblings such as Bitcoin Cash, Bitcoin SV, Namecoin, Ecash, Fractal Bitcoin and Peercoin; its 12 nm ASIC core, dual high-speed fans and aluminum-alloy shell form a compact thermal-management package, while the integrated power supply simplifies cabling at the cost of demanding a stable incoming feed, and firmware that allows voltage tuning alongside automatic thermal throttling gives experienced operators the levers to tune efficiency versus reliability. Operationally this combination implies clear site requirements: disciplined electrical provisioning and surge protection or conditioning to prevent brownouts, structured airflow and rack spacing to avoid heat recirculation, acoustic mitigation where noise matters, and a maintenance cadence that anticipates fan replacement and PSU health-treat spare parts and firmware rollbacks as inventory items rather than afterthoughts. From a systems-strategy perspective, maximize long-term output by combining pooled mining for steadier revenue, proactive firmware updates that close vulnerabilities and refine power curves, and continuous monitoring of hash rate, temperature and uptime so that automated alerts can trigger rapid intervention; use a profitability model that integrates your measured hashrate, current network difficulty, block rewards, pool fees and actual measured power draw to produce daily, monthly and annual projections and run sensitivity analyses against difficulty shifts and utility rate changes to determine break-even horizons and whether to scale, diversify coin targets, or invest in efficiency upgrades. Consider also site-level optimizations such as grouping units to enable waste-heat capture, negotiating power delivery terms to lower effective energy cost per terahash, and planning for decommissioning or resale paths as network economics evolve. Above the metrics and checklists, treat the miner as a body at the threshold between life and silence: every watt sustains its work, every compromised connection risks the void, and the disciplined interplay of cooling, power stability and operational governance is what separates resilient, long-term hash production from intermittent, costly downtime.

The algorithm
Algorithm Information: SHA-256
SHA-256 — what this algorithm is and how it works.
SHA-256 is a cryptographic hash function. NiceHash relies on it for proof-of-work consensus. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.

Based on our real-time ASIC mining profit calculation, the MicroBT Whatsminer M21 is currently most profitable mining NiceHash at your electricity rate of $0.080/kWh. This can change as coin prices and network difficulty shift, so check the Mineable Coins table above for the latest ranking.
This ASIC mining profit calculation for the MicroBT Whatsminer M21 uses live cryptocurrency prices, current network difficulty, and block rewards for every supported coin, combined with your custom electricity rate. Figures update automatically as network conditions change, so the profitability shown reflects current conditions rather than a static estimate.
NiceHash is a hashpower marketplace, not a traditional mining pool — instead of mining a coin directly, you sell your MicroBT Whatsminer M21 hashrate to buyers and get paid in Bitcoin. Compare the NiceHash row against direct-mining rows in the Mineable Coins table above: whichever shows the higher Profit/Day at your electricity rate is currently the better option for this specific miner.
This miner is not currently listed by any of our verified vendors. You can still use the profitability figures on this page to plan ahead for when new listings appear.
