Citibank has downgraded the cryptocurrency trading platform Gemini from neutral to sell, reducing its price target from $13 to $5.50. The bank cited concerns over Gemini's prolonged path to profitability as a key reason for the downgrade. In a related move, Citibank also adjusted its one-year price targets for major cryptocurrencies, lowering Bitcoin's target to $112,000 and Ethereum's to $3,175. These revisions reflect Citibank's cautious outlook on the cryptocurrency market's near-term performance.
