Bitcoin Mining Industry Sells Off Massive Amounts Amid Rising Energy Costs

The Bitcoin mining industry is facing significant challenges as two of its largest players, MARA and Riot, have sold over 32,000 BTC in the first half of 2026. The sales are a result of the industry's struggle to maintain profitability due to declining Bitcoin prices and increasing energy costs.

MARA Holdings sold 23,093 BTC, while Riot Platforms sold 9,665 BTC in the first six months of 2026 alone. This represents more than what many nation-states hold in reserves. Despite this massive liquidation, both companies' stocks have outperformed spot Bitcoin in terms of percentage gains.

The data also shows that Bitcoin mining difficulty has fallen by 15.1% since the beginning of 2026, with ten downward adjustments against only seven increases. This decline is attributed to a combination of factors, including declining network rewards and increasing energy costs.

Riot's Q2 2026 results show that the company mined 1,587 BTC at an all-in cost of $90,631 per Bitcoin, which is 126.5% of the coin's market value at the time of production. This indicates that Riot was mining at a structural loss in Q2 2026.
