Founded in 2016, MicroBT is a Chinese manufacturer of ASIC miners. Its flagship brand, WhatsMiner, is now one of the most trusted names in Bitcoin mining hardware. The company is known for delivering machines that combine strong performance, efficiency, and a solid build.

Reliable Hardware

At captainmining.com, we have seen many clients use WhatsMiner units for years without major issues. These miners run 24/7 and keep working with minimal downtime. Their design is robust, making them perfect for demanding environments.

Performance and Models

WhatsMiner miners are built for the SHA-256 algorithm. This makes them ideal for Bitcoin and other similar coins. The M60 series offers different cooling options—air, hydro, and immersion—so miners can choose what fits their setup.

• M60S / M60S+ (Air-Cooled): Around 210 TH/s with good efficiency.
• M63S / M63S+ (Hydro-Cooled): Up to 390 TH/s with water cooling.
• M66 / M66S (Immersion): Designed for immersion tanks for maximum cooling and stability.

The newer M6XS+ series pushes performance further and is made for industrial-scale farms.

Key Advantages

• High Reliability – Proven track record with long operating life.
• Strong Build Quality – Durable materials and solid engineering.
• Efficiency – Low joules per terahash for better profitability.
• Flexibility – Cooling options for different setups.
• Ease of Use – Simple setup and operation.

Our Experience with WhatsMiner

When it comes to cryptocurrency mining, reliability is often the deciding factor between a profitable long-term setup and a constant source of frustration. Over the years, our work with different ASIC brands has given us a broad perspective on what truly sets certain machines apart. Among them, WhatsMiner models have consistently stood out as some of the most dependable miners available today.

Consistency Above All

From day one, WhatsMiner devices are designed with stability in mind. Once configured, they typically require minimal adjustments, which is a huge advantage for both beginners and large-scale operators. In our hosting facilities, these units run for months without needing intervention, allowing miners to focus on growth rather than troubleshooting. This plug-and-forget quality makes them especially appealing for anyone looking for a long-term solution.

Built Like Tanks

One of the strongest points in favor of WhatsMiner hardware is its durability. Unlike many newer machines that can be sensitive to small fluctuations in temperature, humidity, or voltage, WhatsMiners are remarkably resilient. Their boards are solid, their cooling systems are efficient, and their build quality inspires confidence. Over the years, we’ve seen how well they withstand demanding conditions — a trait that reminds us of the legendary Antminer S9 and Antminer L3, two models famous for their near-indestructible nature. WhatsMiner carries that same reputation forward into the modern mining landscape.

Performance Without Drama

Mining profitability depends on consistent hash rates and minimal downtime. In this regard, WhatsMiners excel. They deliver the advertised performance reliably, and their error rates remain very low compared to other brands. Even in large farms, where hundreds of machines are operating side by side, these units show remarkable uniformity. The result is predictable output, which is essential for calculating ROI and planning future investments.

Minimal Maintenance, Maximum Output

Another reason why we value WhatsMiners so highly is the reduced maintenance burden they place on operators. With many other miners, frequent board swaps, fan replacements, or firmware updates are a reality. WhatsMiners, by contrast, often keep running steadily for years with only basic cleaning and occasional checks. This translates into lower operational costs and less downtime — two key factors that can make or break profitability in today’s competitive mining market.

Trusted by Professionals and Beginners

Whether you are just starting out with one or two machines at home or you are managing a large-scale farm with hundreds of units, WhatsMiners adapt well. Their straightforward configuration makes them approachable for newcomers, while their rugged reliability makes them trusted workhorses for professionals. Many of our clients who started with other brands eventually switched to WhatsMiner after experiencing recurring issues, and most of them never looked back.

The Long-Term Safe Choice

In a rapidly evolving industry, where new models are released every year and promises often exceed reality, WhatsMiners provide something rare: peace of mind. They may not always be the cheapest upfront, but their long lifespan and stable performance make them one of the most cost-effective choices over time. For anyone seeking a safe, long-term mining investment, WhatsMiners remain one of the best bets on the market.
