CleanSpark's Bitcoin Treasure Grows: How the Mining Giant Added 629 BTC in September While Cashing Out $49 Million

CleanSpark Expands Bitcoin Holdings to Over 13,000 in September

Bitcoin mining company CleanSpark has significantly increased its Bitcoin holdings during September 2025, with its stack now exceeding 13,000 BTC. This growth represents an important milestone for the mining operation as it continues to strengthen its position in the cryptocurrency mining sector.

September Mining Production

According to the available information, CleanSpark produced 629 Bitcoin during September. This production rate demonstrates the company's substantial mining capacity and operational efficiency during the month.

While building its reserves, the company also engaged in strategic selling. CleanSpark sold 445 Bitcoin tokens in September, generating approximately $49 million in revenue. This selective selling approach allows the company to monetize a portion of its mining rewards while continuing to grow its overall holdings.

Strategic Balance: Holding vs. Selling

The data reveals CleanSpark's balanced approach to Bitcoin management:

• Mined: 629 BTC in September
• Sold: 445 BTC (approximately $49 million)
• Retained: The difference added to their holdings, which now exceed 13,000 BTC

This strategy suggests the company is maintaining operational liquidity through partial sales while simultaneously building its long-term Bitcoin reserves. At current market rates, the company's 13,000+ Bitcoin holdings represent a significant asset on its balance sheet.

Mining Industry Context

CleanSpark's ability to mine 629 Bitcoin in a single month positions it as a substantial player in the Bitcoin mining ecosystem. While the information doesn't specify the exact mining equipment or energy sources used, the production volume indicates significant computational resources and operational scale.

The company's decision to hold more than 13,000 Bitcoin also suggests confidence in the long-term value of the cryptocurrency, even as they liquidate a portion of their production to cover operational costs and potentially fund further expansion.

Financial Implications

The sale of 445 Bitcoin for approximately $49 million provides insight into the average sale price achieved by CleanSpark in September. This translates to roughly $110,112 per Bitcoin, though the exact timing and nature of these sales (whether gradual or in batches) isn't specified in the available information.

These funds likely support the company's ongoing operations, including electricity costs, equipment maintenance, and potential expansion of mining capacity.

Looking Forward

While the source doesn't provide information about CleanSpark's future plans, the substantial increase in Bitcoin holdings suggests the company is positioning itself for long-term participation in the cryptocurrency ecosystem. The balance between holding and selling indicates a strategic approach to managing assets while maintaining operational sustainability.

As the Bitcoin mining landscape continues to evolve, companies with significant holdings like CleanSpark may be well-positioned to benefit from potential future price appreciation while generating ongoing revenue through their mining operations.
