Grayscale wrote a letter to the U.S. Securities and Exchange Commission (SEC) on Thursday calling for the agency to simultaneously approve any qualifying Bitcoin spot ETF applications, so as to not “pick winners and losers.”

However, the firm also argued that Coinbase shouldn’t qualify as a surveillance partner to launch such a product, under the SEC’s pre-established rules.

Why Coinbase Isn’t Good Enough
