Barclays has lowered its price target for Coinbase to $291, a reduction of 18% from the previous target of $357. The adjustment reflects ongoing regulatory risks and market volatility affecting the cryptocurrency exchange. Despite these challenges, Barclays maintains an 'Equal Weight' rating, suggesting that the stock is fairly valued at current levels. Coinbase's focus on regulatory compliance and its diverse product offerings are highlighted as key strengths by Barclays. Meanwhile, market participants are closely monitoring the fear and greed index for potential shifts in investor sentiment, which could influence altcoin movements if risk appetite increases.
