The Securities and Exchange Commission (SEC), led by Chairman Gary Gensler, has been at the forefront of the United States' cryptocurrency crackdown. In the last few months, the agency has filed several enforcement actions against major crypto companies that allegedly violated security laws.
Critics say the agency has adopted a regulation-by-enforcement approach without providing a proper set of rules that fit the unique features of crypto assets. A major source of confusion is the definition of a security and whether it can apply to a highly diverse set of assets such as cryptocurrencies.
