WASHINGTON, July 13 (Reuters) - Partnering with Coinbase Global (COIN.O) may hinder rather than help Nasdaq's (NDAQ.O) bid to win regulatory approval for a bitcoin exchange-traded-fund it wants to launch with BlackRock (BLK.N). The SEC has denied previous spot bitcoin ETF proposals on the basis that they would be vulnerable to manipulation. The SEC last month sued Coinbase, escalating SEC chair Gary Gensler's crackdown on the crypto industry. And with roughly 56% of U.S. dollar bitcoin trading, according to Nasdaq's filing, Coinbase is integral to the U.S. bitcoin market. All told, the SEC has 240 days after it accepts the bitcoin ETF filing applications to make a decision.
