According to online reports, Matthew Sigel, director of digital assets at VanEck, said at the Bitcoin 2025 conference in Las Vegas that the "most feasible path" to establish a permanent U.S. strategic bitcoin reserve is through "targeted amendments to congressional budget legislation." He pointed out that the amendments could include "tax credits for mining companies that use methane gas" and encourage miners to "turn over some of their bitcoins to the federal government." Sigel said this would allow reserves to "grow naturally over time."
