VanEck, an asset management firm, said that if the United States builds 1 million reserves of bitcoin as proposed by Senator Cynthia Lummis, the national debt could be reduced by 35% over the next 24 years. VanEck's estimates assume bitcoin will grow at a 25% compound annual growth rate (CAGR) to $42.30 million in 2049, while U.S. Treasuries will climb at a 5% compound annual growth rate from $37 trillion in early 2025 to $119.30 trillion in the same period. Matthew Sigel, head of digital asset research at VanEck, and Nathan Frankovitz, an investment analyst, said in a Dec. 20 note: 'The reserve could account for 35 percent of the national debt by 2049, offsetting about $42 trillion in liabilities.'
