Odaily reports that as resource competition intensifies, US Bitcoin mining companies are accumulating cryptocurrency funds to help them withstand tightening profit margins. Since last November, companies like Mara Holdings, Riot Platforms, and CleanSpark have raised over $3.7 billion from investors, which they then use to purchase Bitcoin. These companies typically raise funds through zero-interest (or near-zero-interest) convertible notes. CoinShares research head James Butterfill said, "If Bitcoin prices don't rise, we'll see a lot of miners start to shut down or go bankrupt." Executives say the bigger challenge comes from large AI developers with more financial resources than miners. Core Scientific Chief Development Officer Russell Cann said, "US AI demand will greatly impact how much Bitcoin mining can increase," predicting that most of Bitcoin's computing power will be outside the US in the coming years. "It can only be explained mathematically: is the optimal use of the grid as a Bitcoin mining facility or as an AI data center? Currently, from an economic standpoint, AI will be the optimal use," Cann said. Additionally, Mara aims to move half of its mining operations overseas by 2028 and expand to energy-surplus locations like Kenya, the UAE, and Paraguay.
