Environmental regulators should seek “a comprehensive analysis as it relates to understanding the potential environmental effects of digital asset mining,” according to the letter, which was signed by Sen. Cynthia Lummis (R-Wyo.), one of the authors of new legislation to regulate crypto, and Rep. Patrick McHenry (R-N.C.), the ranking Republican on the Financial Services Committee, along with three other senators and nine members of Congress. They insisted the U.S. government shouldn’t do anything to disrupt American leadership in the sector.
