Ethereum has seen a significant increase of over 58% in the past 30 days, with almost 40% of that surge occurring in the last 10 days. Despite this notable rally, various important indicators are showing signs of caution.

The BBTrend for Ethereum has recently turned negative, currently standing at -0.02 after maintaining a positive trend for approximately seven days straight. This reversal follows a peak of 28.39 on May 12, possibly indicating the end of the bullish phase.

Furthermore, Ethereum whale accumulation is declining, with addresses holding between 1,000 and 10,000 ETH decreasing below 5,400 for the first time since April 9. This is deemed a crucial level as these large holders have historically influenced market movements.

Additionally, Ethereum's short-term EMA momentum is stalling, with the short-term lines flattening and closing in on the long-term lines. Although the overall trend remains positive, the loss of upward momentum introduces short-term uncertainty.

These signals collectively suggest Ethereum might be reaching a critical juncture where increased buying pressure is necessary to maintain its upward trend, or else it risks a potential reversal.
