According to Cointelegraph, ETF issuers VanEck, 21Shares, and Canary Capital have sent a letter to the US SEC urging the restoration of the "first come, first served" principle and approval of ETF applications in the order they are submitted to regulatory agencies. These companies argue that the SEC's failure to comply with the "first to file principle" (i.e. the default application approval process before the listing of cryptocurrency ETFs) has weakened healthy competition and hindered financial innovation.
