TechFlow News, March 27: According to Cointelegraph, following mining company MARA’s sale of a portion of its Bitcoin holdings, Twenty One Capital—founded by Jack Mallers—has become the second-largest publicly listed Bitcoin treasury company, currently holding 43,514 BTC, valued at over $2.9 billion, trailing only Strategy’s 762,099 BTC.
MARA sold a cumulative total of 15,133 BTC in March 2026, raising approximately $1.1 billion and dropping to third place. Analyst Tyler Rowe noted that MARA aggressively borrowed during the bull market to accumulate Bitcoin; it is now forced to sell at a loss to repay debt—a development that validates long-standing external warnings about debt-driven treasury strategies.
