Over the past year, leading manufacturers of application-specific integrated circuit (ASIC) bitcoin mining rigs have introduced a range of cutting-edge devices. Many of these rigs are quickly snapped up by major mining enterprises, often disappearing from shelves shortly after release. Below is an exploration of the availability of these bitcoin miners for the average enthusiast—a closer look at what’s accessible for the average individual aiming to acquire a few units from two prominent manufacturers.
The Cost of Mining—Breaking Down Air-Cooled Options From 2 Manufacturers for Hobbyists
As of Jan. 12, 2025, the roster of ASIC bitcoin mining machine manufacturers remains compact, with industry leaders Bitmain and Microbt among them. In 2024, both companies introduced an array of innovative rigs, some of which are scheduled to debut this year. With that in mind, we explored their latest offerings to see what’s currently available on their respective websites for an ordinary person. Keep in mind, however, these high-tech devices come with price tags in the thousands of dollars.
It’s worth noting that hydro and immersion-cooled ASIC miners are unlikely to suit casual hobbyists or the average individual. These systems require intricate setups and ongoing maintenance, often demanding technical expertise beyond what most casual miners possess. For this analysis, we’ll focus specifically on the pricing, performance, and availability of air-cooled bitcoin miners from Bitmain and Microbt.
Bitmain’s online store currently offers only one air-cooled bitcoin miner available through a futures order, meaning buyers secure the device now for later delivery. The Antminer S21+, priced at $4,644, is slated for shipping in Q1 2025. This machine delivers 216 terahash per second (TH/s) with an efficiency rating of approximately 16.5 joules per terahash (J/T). At $4,644 per unit, this translates to about $21.50 per terahash. Payments can be made in USD, bitcoin (BTC), ethereum classic (ETC), or tether (USDT).

In contrast, Microbt’s Whatsminer platform features a wider selection, with eight air-cooled units available for purchase. The most affordable option is the Whatsminer M50, which generates between 110 and 114 TH/s and costs $946. The M50S+ is priced at $1,711.20, offering a hash rate of 138 TH/s. In terms of efficiency, the M50 achieves 29 J/T, while the M50S+ operates at 24 J/T. For higher performance, Microbt also offers the air-cooled M60S++ unit, delivering around 220 TH/s but priced at $5,478, equating to $24.90 per terahash.

Microbt’s catalog includes other models, such as the M60 and M60S+, which provide 154 TH/s and 188 TH/s, respectively. The M60 is priced at $2,310, with an efficiency rating of 21 J/T, while the M60S+ costs $3,929 and operates at 17 J/T. The M60S, another option, produces 184 TH/s at $3,367.20 per unit. Additionally, the air-cooled M50S and M50S++ units are available at discounted rates of $1,267 and $1,624 during a 17-day flash sale, though these prices are subject to change. The M50S delivers 128 TH/s with an efficiency of 26 J/T, while the M50S++ achieves 140 TH/s at 24 J/T.
Both Bitmain and Microbt also provide hydro and immersion-cooled bitcoin miners, though these models are significantly more expensive and tailored for advanced setups. Bitmain offers four hydro-cooled units currently available and two additional models under future shipping terms. Microbt lists six systems designed for hydro and immersion cooling, all available for immediate order.

While these advanced units come with higher price tags, they also boast superior performance and efficiency. For example, Bitmain’s S21 XP Immersion-cooled Antminer costs $7,368, delivering an output of 300 TH/s and an efficiency rating of 13.5 J/T. Similarly, Microbt’s hydro-cooled Whatsminer M63, priced at $7,368, offers 366 TH/s with an efficiency rating of 19 J/T. These types of devices cater to operators seeking top-tier performance and are willing to invest in the associated complexity and cost.
Bitcoin mining, even with air-cooled machines, is far from a plug-and-play endeavor. Beyond the initial cost of the hardware, prospective miners must contend with substantial energy demands. These machines require a reliable and affordable electricity source to operate efficiently, and without it, profitability diminishes quickly. Additionally, managing heat output and ensuring proper ventilation are critical. For those diving into mining, understanding these practicalities is essential to turn ambition into sustainable participation in the bitcoin network.
