Famous U.S.-based bitcoin miner MARA Holdings has released its Bitcoin operation and mining results for May 2025. It has revealed a substantial 950 bitcoins (BTC) boost to its investment portfolio amid different mining challenges and the crypto market volatility.
MARA adopted a strategic bitcoin reserve in 2024. Since then, it has periodically hit the market for bitcoin shopping. It has also regularly filled its stash with all of its mined BTC, standing by its “bitcoin first, bitcoin only” strategy.
50,000 BTC Milestone Incoming
Following MARA’s profitable May mining activities, its bitcoin holdings have grown to contain 49,179 BTC, leaving it just 821 units away from securing 50,000 units of the world’s leading cryptocurrency.
Commenting on MARA May’s success, its CEO, Fred Thiel, said, “May was a record-breaking month for MARA with 282 blocks won, a 38% increase over April and a new monthly high. Our total bitcoin holdings surpassed 49,000 BTC during May, and the 950 bitcoin produced were the most since the halving event in April 2024.”
Remarkably, the 2024 Bitcoin halving reduced mining rewards by 50% to 3.125 BTC per block. Due to the reduced rewards, a handful of miners were unable to survive in the market, so they shifted their business patterns or quit their bitcoin mining operations. Amid this miner capitulation, MARA maintained its stand and has recorded improvements in its operations.
Due to the addition of mining rewards to its stash, calculating how much MARA has spent on BTC could be a herculean task that yields an uncertain result. However, with the current spot bitcoin price above $104,000, the miner’s bitcoin holdings are worth over $5.1 billion.
K33 Joins BTC Adoption Train
In a recent development, K33, a digital asset broker and research firm, has made a strategic move to join the list of firms with BTC in their balance sheet. As revealed by the firm on Tuesday, it has acquired its first 10 BTC and plans to reach the 1,000 BTC milestone as soon as possible.
“This is more than a transaction. It’s the opening move in a long-term strategy rooted in conviction and operational synergies,” the firm noted in its official X post.
Meanwhile, following a two-week-long downtrend, the leading cryptocurrency has made a few bullish moves, signaling a potential breakout from the one-hour order block, which could lead to a price recovery.
