According to CoinDesk, American Bitcoin (ABTC), a Bitcoin mining company associated with the Trump family, announced that President and interim Chief Financial Officer (CFO) Matt Prusak will leave on August 4 to join AI and energy infrastructure company Giga Energy as Chief Business Officer and interim CFO.Prusak stated that after "years of building the Bitcoin business," he will shift to the upstream energy infrastructure sector, focusing on the current power supply issues that limit the development of Bitcoin mining and AI computing.American Bitcoin was co-founded by Eric Trump and supported by Hut 8, and it is a publicly traded Bitcoin mining company listed on NASDAQ. Prusak was previously responsible for driving the company's Bitcoin accumulation strategy, including expanding hash power and increasing the BTC holdings per share.Giga Energy, headquartered in Houston, primarily develops power equipment and AI data center infrastructure. The company stated that it has delivered over 6.5GW of power infrastructure and is developing over 500MW of AI data center capacity.Industry insiders believe that Prusak's transition reflects the accelerating migration of the Bitcoin mining industry towards the AI infrastructure sector. As competition in the mining business intensifies and profit margins are pressured, more mining companies are beginning to leverage their own power resources, land reserves, and data center capabilities to enter the AI computing infrastructure market.As large tech companies compete for power and data center capacity, energy supply has become a core bottleneck for the expansion of AI computing, and companies with the ability to integrate power resources are gaining more attention.

ChainCatcher news, according to The Block citing Business Insider, after the unannounced release of an interview between FTX founder Sam Bankman-Fried (SBF) and Tucker Carlson on Thursday, SBF's crisis PR manager has resigned. Mark Botnick started representing SBF after the collapse of his cryptocurrency exchange FTX in November 2022, and he resigned on Thursday after learning about the interview. This is the second interview SBF has given since breaking his two-year public silence after being incarcerated. These interviews seem to be part of his attempt to seek a presidential pardon.

From the billions in funds collapsing at FTX to the year he faced court proceedings, SBF has given countless media interviews, sometimes getting himself into trouble. On one occasion, he even showed a reporter his ex-girlfriend's diary, which led to his imprisonment to prevent potential witness tampering. Botnick reportedly worked with SBF during this time. It is said that the PR manager was also caught off guard when SBF posted on X about the Trump administration's attempts to fire federal employees.
