The concept of the "Bitcoin race" refers to the global competition among nations and entities to adopt, regulate, or dominate the cryptocurrency landscape, particularly Bitcoin. This race has intensified as Bitcoin's value and influence in the financial world have grown. Senator Cynthia Lummis, as highlighted in the post you mentioned, advocates for the U.S. to lead this race, drawing parallels to historical competitions like the Space Race. The idea is to position the U.S. at the forefront of cryptocurrency innovation and adoption, potentially through legislative measures that could include establishing a strategic Bitcoin reserve. This reflects a broader trend where countries like El Salvador and the Central African Republic have already taken steps to recognize Bitcoin as legal tender.
