Coinbase has garnered significant support in its legal challenge against the SEC, with multiple entities including the Crypto Council for Innovation, Paradigm, LEJILEX, SatoshiActFund, TexasBlockchain, and the US Chamber of Commerce submitting amicus briefs. These briefs were filed in response to the SEC's refusal to provide clear regulations for the cryptocurrency industry, a stance Coinbase is contesting in the Third Circuit court. The collective action underscores the industry's push for regulatory clarity and highlights the broader debate over the SEC's approach to cryptocurrency regulation.
