On March 18, Coin Center sent a letter to the US SEC, calling for prioritizing the formulation of systematic cryptocurrency asset regulatory rules to avoid market fragmentation and unfairness. The letter pointed out that crypto networks should be viewed as public infrastructure. The SEC recently issued a classification of non-security crypto assets and signed a memorandum of understanding with the CFTC, aimed at strengthening regulatory coordination. Coin Center warned that selective regulation could affect market fairness. The US Congress is advancing the CLARITY Act, expecting to provide a clear compliance pathway for digital assets.
