Mara Holdings, the owner of the second-biggest BTC treasury, reached a milestone of holding 50K BTC. The mining company relies on its growing hashrate to boost its reserves.
Mara Holdings (MARA) announced the milestone of building up its treasury to 50,000 BTC. Unlike other treasury companies, Mara Holdings combines a growing mining operation with occasional purchases.
The company announced it plans to double down on expanding its mining operations, reaching 75 EH/s by the year end.

Mara Holdings started out at 27,000 BTC in the last quarter of 2024, taking up a series of deliberate purchases. After that, the company continued to accrue coins more slowly through its native mining operations. Currently, Mara Holdings has an unknown BTC acquisition price, but its costs may be lower compared to the newer wave of treasury companies.
The company has also announced a $2B plan to buy more BTC, though the shares would be sold at intervals on the discretion of Mara Holdings. So far, the mining company has not shown any significant moves to acquire BTC more rapidly, instead focusing on mining operations.
Mara Holdings grew its treasury in the past 12 months
In the past 12 months, Mara Holdings nearly tripled its treasury, though it did not have a clear plan for copying Strategy (MSTR). The Mara.com pool currently produces around 7% of all blocks, with around 45 EH/s in active mining power.
Based on its known wallets, Mara Holdings also mines as part of the Foundry pool, further putting its hashrate to work. Mara Holdings added 761 BTC to its wallets in June, following an inflow of 950 BTC in May, with none of the new coins sold. May was an absolute monthly record, followed by a slowdown in June, mostly due to weather conditions, stated Mara Holdings in its recent half-year report.
The Bitcoin mining rate remains high, at over 1,000 EH/s for the entire network, despite the recent slowdown due to a heatwave.
Mara Holdings has outpaced all other miners in its readiness to hold onto the newly produced BTC. Miner reserves remain at 1.89M coins, though not all are dedicated to treasuries. Other mining companies like Riot Platforms and CleanSpark have retained significant reserves, though they do not explicitly mention a treasury plan. Even before the announcement, MARA shares expanded by over 15% in the past week, trading at $16.78. MARA is at a one-month peak following a record month for BTC treasury companies.
The past month marked another high tide for treasury companies. Over 68K BTC was taken off the market, ranging from large-scale purchases by Strategy to deals for under 10 BTC from virtually unknown businesses.
In total, corporate buyers made 250 announcements, coming from companies in healthcare or even coffee sales. A total of 21 new treasuries were announced, buying around 6,745 BTC. A total of 141 public companies now hold BTC, with more funding rounds announced.
