Bitcoin Mining Production Slumps as MARA Plans 40% Network Capacity Boost

Key Takeaway: 

• Despite a 25% production drop, MARA’s $5.3 billion BTC reserve shows institutional-grade diamond hands.
• MARA’s 3GW power pipeline reveals that captive energy is the new competitive moat.
• While MARA expands, Bit Digital shifts to Ethereum staking.

MARA Holdings' latest public report reveals a 25% month-over-month decline in Bitcoin production for June, with output falling from 950 BTC( 282 blocks) in May to 713 BTC (211 blocks). 

MARA attributed the decline primarily to weather-related curtailments at its Texas sites and the temporary deployment of older ASIC rigs in Garden City while crews repaired storm damage.

MARA Holds Firm: $5.3B Bitcoin Treasury Untouched Despite Production Challenges

Despite operational challenges, MARA retained its entire Bitcoin treasury, ending June with 49,940 BTC (currently valued at $5.3 billion) without liquidating any holdings.

Looking ahead, the firm plans to expand its network capacity by over 40%, aiming to reach 75 EH/s by the close of 2025.

This expansion hinges on securing 1.7 GW of captive power capacity, including 1.1 GW already operational and a development pipeline exceeding 3 GW of low-cost energy opportunities.

As Bitcoin's mining difficulty rises, miners face mounting pressure to upgrade hardware and secure cheaper power for their operations. MARA’s focus on efficient capital deployment and captive power positions the company with a likely advantage.

Bit Digital announced a strategic pivot on June 26, raising $150 million via share sales to transition from Bitcoin mining to Ethereum staking. The move aims to enhance treasury flexibility and tap into DeFi demand.

Meanwhile, Norway is considering a temporary ban on crypto mining data centers as early as autumn. Authorities cite concerns over energy consumption under the Planning and Building Act and aim to gather detailed usage data before deciding on permanent measures.
