Citi said in a research note on Tuesday that crypto exchange Coinbase (COIN) could benefit from improved regulation after the U.S. presidential election in November and the Supreme Court's overturning of the Chevron case, and upgraded its rating on the stock. Citi upgraded Coinbase's rating from neutral to buy and raised its price target from $260 to $345. In addition, the report said that the launch of a spot Ethereum ETF would help drive wider adoption of cryptocurrencies and bring greater custody revenue opportunities to Coinbase. (Coindesk)
