NHL taps Kalshi and Polymarket as official prediction market partners

The 30th edition of the HODL (Formerly World Blockchain Summit), the world's longest-running Crypto & Web3 Summit series is set to return to Dubai.

Ethereum founder, Vitalik Buterin, has unveiled new goals for the Ethereum blockchain today at the Japan Developer Conference. The plan lays out short-term, mid-term, and long-term goals touching on L2 interoperability and faster responsiveness among others. In terms of technology, he said again that he is sure that Layer 2 options are the best way […]

Three of China’s largest Bitcoin hardware manufacturers are establishing production facilities in the United States as President Donald Trump’s tariff policies reshape the cryptocurrency industry. The three industry leaders, Bitmain, Canaan, and MicroBT, collectively control over 90% of the global mining rig market. These companies are the architects of Bitcoin’s physical infrastructure, manufacturing the specialized ASIC (Application-Specific Integrated Circuit) machines that form the backbone of the world’s most valuable cryptocurrency network. Every Bitcoin mined globally likely passes through hardware bearing Chinese engineering fingerprints. 95% Market Control Sparks “Digital Dependency Trap” and Security Risks According to a June 18 Reuters report, these Bitcoin mining giants are establishing U.S. operations to circumvent potential tariffs. However, critics have raised security concerns about Chinese involvement in sectors spanning semiconductor manufacturing and energy infrastructure. Guang Yang, chief technology officer at crypto technology provider Conflux Network, described the situation as extending beyond trade policy. “The U.S.-China trade war goes beyond tariffs,” Yang stated. “It’s a strategic pivot toward ‘politically acceptable’ hardware sources.” Bitmain, the largest of the three companies by revenue, initiated U.S. production of mining equipment in December , one month after Trump’s presidential election victory. Canaan began trial production in the United States on April 2 to avoid tariffs following Trump’s announcement of new trade levies.

When measured by computing power sold, these three Chinese companies command 95.4% of the global market share. The Bitcoin ecosystem encompasses five primary segments: hardware supply, mining farm operations, mining pool management, trading platforms, and payment processing services. Hardware manufacturers like Canaan, the first Bitcoin mining company to go public and the second-largest by computing power , focus exclusively on integrated circuit (IC) design, manufacturing, and equipment sales. Industry analysts project continued sector expansion, with the market expected to reach $11.9 billion by 2028, representing a compound annual growth rate of 15.3%, contingent on Bitcoin’s continued price appreciation driven by supply scarcity. Source: Frost & Sullivan China’s Historical Bitcoin Mining Advantage Understanding today’s migration requires examining how China achieved such overwhelming market control in the first place. The foundation was laid during the historic 2017 Bitcoin boom, when three key factors aligned to create Chinese mining supremacy. During the early expansion phase, Chinese officials recognized cryptocurrency mining as a profitable venture that attracted substantial foreign investment. Consequently, authorities initially overlooked the mining sector while simultaneously restricting Bitcoin trading and initial coin offerings.

Does Chinese Hardware Control America’s Bitcoin Network? While the United States leads global Bitcoin mining operations with over 38% of total network activity , American miners depend almost entirely on Chinese-manufactured equipment. America Leads Bitcoin Mining Operation/ Source: Bitbo This creates what security analysts describe as a “digital dependency trap,” a scenario where America’s cryptocurrency infrastructure relies fundamentally on hardware produced by its primary economic rival. Guang Yang, Conflux Network’s chief technology officer, frames this dependency in geopolitical terms that extend far beyond trade economics . “The U.S.-China trade war goes beyond tariffs,” Yang explains. “It’s a strategic pivot toward ‘politically acceptable’ hardware sources.” His assessment reflects growing concerns within the cryptocurrency community about supply chain vulnerabilities that could impact national economic security.
