On March 17, according to Crypto In America, Canadian bitcoin mining company Bitfarms announced that it had successfully completed an all-stock acquisition of Stronghold Digital Mining with a transaction value of more than US$110 million, making it the largest merger between two listed bitcoin mining companies. The acquisition will increase Bitfarms 'share of the North American energy market from 6% to 80%, especially in the U.S. PJM grid. It is worth noting that Riot Platforms, the world's second-largest bitcoin mining company, tried to hostile acquisitions of Bitfarms, but ultimately failed and chose to hold a 20% stake in Bitfarms. In addition, the U.S. SEC will hold an industry roundtable on Friday to discuss the securities properties of crypto assets, which is expected to affect the direction of future industry supervision. At the same time, New York is hosting multiple crypto industry conferences this week, including Tokenize NYC, Blockworks DAS and Medici NY, attracting the participation of many industry leaders and policymakers.
