Bitcoin Miner Cleanspark Adds 454 BTC at $64K While Others Sell Into the Bear Market

Bitcoin miner Cleanspark (Nasdaq: CLSK) purchased 454 BTC worth about $29 million on July 7, lifting its treasury to 13,924 BTC even as much of the mining industry sells coins to survive the bear market.

Key Takeaways

• Cleanspark bought 454 BTC for about $29 million on July 7 at an average price near $64,000.
• The miner’s treasury now totals 13,924 BTC, worth roughly $880 million.
• Public miners sold a record 32,000+ BTC in Q1 2026, making Cleanspark’s accumulation a contrarian bet.

Swimming Against The Tide

The purchase was made at an average price of roughly $64,000 per coin, according to trackers, pushing the Las Vegas-headquartered company to within striking distance of 14,000 BTC (while simultaneously cementing its place among the largest bitcoin holders in the public mining sector).

Publicly listed miners sold more than 32,000 BTC combined in the first quarter of 2026, a record that surpassed their full-year 2025 total, with Marathon alone selling more than 20,800 BTC to retire debt and fund expansion.

Against that backdrop, a miner adding nine figures’ worth of bitcoin is quite the statement, suggesting conviction in prices going up over the coming weeks.

The Numbers Show Heavy Bleeding

Bitcoin.com News reported that Cleanspark posted a $378.3 million net loss for its fiscal second quarter ended March 31, driven largely by a $224.1 million non-cash loss on the fair value of its bitcoin as prices fell. The same filings showed the company holding $925.2 million in bitcoin and $260.3 million in cash at quarter-end, meaning the treasury itself remains the balance sheet’s center of gravity.

Fair-value rules force miners to mark their bitcoin to market each quarter, so the same stack that produced a paper loss in the spring would swing to gains in any recovery (a leverage effect Cleanspark is effectively increasing with each purchase).

Also, Cleanspark has consistently characterized its purchases as opportunistic, adding coins routinely during market weakness rather than at euphoric tops. Buying at an average near $64,000 is concurrent with that sentiment.

Lastly, it bears mentioning that mining stocks have held up better than the asset they produce this year, and miner equities as a group have outperformed BTC this year.

In that regard, a miner that holds rather than sells its production must fund operations from other sources, and a deeper bitcoin decline would compound both the operating squeeze and the mark-to-market losses. For the time being, the message from the July 7 purchase is unambiguous, i.e. while competitors sell the bear market, Cleanspark is buying.
