Wall Street firm Bernstein predicts Coinbase's stock price will gain from the recent Ethereum (ETH) surge. Their analysis suggests that the ETH rally signals the beginning of "alt season," benefiting Coinbase due to its extensive listing of over 250 cryptocurrencies. Bernstein anticipates a substantial increase in cryptocurrency trading volume during the third and fourth quarters, leading to higher fee revenue for Coinbase. The availability of diverse altcoins on Coinbase provides traders with more options, potentially driving increased activity on the platform. This analysis suggests a positive outlook for Coinbase, contingent on the continued strength of Ethereum and the broader altcoin market. ```
