Uniswap (UNI) is experiencing bearish sentiment as the 6 USD neckline resistance failed to hold on December 26. Despite the recent transaction fee switch proposal, the 4-hour KDJ death cross indicates weakening momentum. The 6 USD level aligns with the daily MA60 resistance, and a sustained close above this level is needed to confirm a breakout. However, if the fear and greed index remains negative, a breakdown below 5.6 USD is likely. Traders are closely monitoring for a potential retest of key support levels as market sentiment continues to influence UNI's short-term outlook.
