The creation of a United States digital dollar would “crowd out” the cryptocurrency ecosystem and protect the national security of the U.S. according to a former top advisor in president Joe Biden’s administration. Daleep Singh — a former Deputy National Security Advisor for International Economics in the Biden administration — made the comments at a Feb. 28 Senate Banking Committee hearing, suggesting that cryptocurrencies facilitate ransomware attacks and contribute to the evasion of U.S. sanctions. Singh believes the U.S. government embracing a Central Bank Digital Currency (CBDC) “is the single best step that we could take [to protect national interests] because it would crowd out the ecosystem of crypto.” (Cointelegraph)
