MARA increases Bitcoin production by 35% amid new hashrate highs

Mara Holdings, one of the largest publicly traded Bitcoin mining companies in the United States, has significantly increased BTC production in May despite growing mining difficulty and rising hashrate.

Mara produced 950 Bitcoin (BTC) in the month of May, recording a 35% increase month-over-month (MoM), the company reported in its unaudited BTC production update published on June 3.

The mining company has also posted a record high of 282 blocks earned last month, a 38% increase MoM.

Zero Bitcoin sold

According to MARA’s chief financial officer, Salman Khan, the company saw a record production month in May and has sold 0 Bitcoin.

“One of our biggest competitive advantages? Operating our own mining pool,” Khan wrote in an X post on Tuesday, June 3.

The significance of operating a pool

According to Thiel, Mara’s fully integrated tech stack is a “key differentiator,” as the company is the “only self-owned and operated mining pool among public miners.”

“Operating our pool means no fees to external operators and retention of the full value of block rewards,” he said.

The CEO added that May’s production benefited from block reward luck. “Since launch, MARA Pool’s block reward luck has outperformed the network average by over 10%, contributing to our industry-leading block production,” he stated.

Rising hashrate and difficulty

Mara’s record mining update comes despite Bitcoin mining becoming harder and harder.

Bitcoin hashrate, or an indicator referring to the total computational power used by miners to solve complex math problems and verify Bitcoin transactions on the network, has been surging to all-time high levels in the past few months.

According to Blockchain.com, the BTC mining difficulty rate surged past 126 trillion in another upward adjustment on May 30.
