According to PANews, ETF issuers VanEck, 21Shares, and Canary Capital have written to the U.S. Securities and Exchange Commission (SEC), urging the reinstatement of the 'first come, first served' principle. This principle involves approving ETF applications in the order they are submitted to the regulatory body. The companies argue that the SEC's failure to adhere to this principle has hindered healthy competition and obstructed financial innovation in the crypto ETF market.
