A Houston-based seller is looking to offload six Bitmain Antminer S21 machines, all sealed in their original boxes. These units, known for their solid mining power, remain unused and could serve as a substantial asset for crypto enthusiasts or miners looking to expand their hardware portfolio.
The seller, who commented on various forums, reports that these machines have been kept in a climate-controlled environment and have never been deployed. This offers an attractive deal compared to current retail markets, where similar units exceed $3,200.
"Iβd rather move these to someone who will actually plug them in," stated the seller, indicating a preference for genuine mining interests over mere reselling.
Condition: 5 units factory sealed, 1 unit opened (never powered on)
Power: Each machine operates at 200 TH/s at 17.5 J/TH
Pricing: $1,800 per unit individually or $10,000 for all six units (approximately $1,667/unit)
Payment methods: Crypto preferred, with Venmo and Zelle also accepted
Shipping: Local pickup in Houston or nationwide shipping via UPS (insured)
While the original Bitmain warranty has expired, the seller reassures potential buyers of the machines' pristine condition. "No wear, no dust, no hashboard issues," they emphasized.
The reaction from interested parties appears positive, with many engaging in direct inquiries.
Some notable quotes include:
"Just messaged you"
"Got six S21s sitting in storage that need a new home."
π‘ The demand for high-performance mining equipment remains strong.
π° At $1,667 per unit, the offer is significantly lower than retail, attracting attention.
π Local buyers can inspect the units before purchase, which many see as a valuable step.
As cryptocurrencies remain a key component of financial discussions, hardware that supports mining operations is still relevant to many. With the unveiling of this sale, local miners in Houston may confront a new opportunity to boost their operations with reliable, high-output machines.
For those in the market, securing these Antminers may require quick action, as interest continues to ramp up.
Thereβs a strong chance that local miners in Houston will take swift action as interest in the Antminer S21 machines grows. Given the limited availability of high-performance mining equipment and the attractive pricing, more buyers may emerge, potentially leading to a quicker sale than anticipated. Experts estimate that if the machines sell within the next two weeks, it could spark renewed enthusiasm in the local crypto-community for hardware investments, driving demand for similar deals across forums and local user boards.
Drawing a parallel to the late 1990s tech boom, we recall how outdated computer hardware was quickly repurposed during the rise of the internet. Many individuals upgraded to newer models, but loads of stable, previously owned systems were passed along for a fraction of their costs, enabling hobbyists and emerging startups to thrive. Just like those early computer buyers leveraging low-cost options for innovation, todayβs miners may find surprising opportunities to enhance their setups with these Antminers, igniting a new wave of interest and activity in the crypto space.
