3 Reasons Why Ethereum Price Could Peak in the Weakest Month

September has historically been the weakest month for Ethereum, with an average profit fall of over 12%. This year, September is no different. The capital flight from ETFs and the general market hesitation have put pressure on the price of Ethereum in the first week. However, September 2025 may not unfold according to history. Three bullish signs have emerged, which could reverse the situation and push the price of Ethereum to new highs, during its weakest month in history. Well, that would be a real shock. Whales Buy Big When the Weak Pull Back At the time of the press report, Ethereum is trading around $4,406. Just this week, ETH hit a low of $4,261 but quickly regained its upward momentum. In the past 24 hours, the price of ETH has remained relatively stable, showing no signs of a breakout theoretically. However, whales (whale) have been accumulating strongly. The supply held by external exchange whale wallets has increased from 95.72 million ETH to 99.41 million ETH in less than a day. This figure corresponds to a net purchase of 3.69 million ETH, worth over 16 billion dollars at current prices.

Large capital flows from whales indicate confidence. While retail traders may hesitate, whales seem to be preparing for a price surge. But the buying of whales may face resistance if retail investors, especially those holding short positions, sell. It seems that this has also been addressed. Their buying coincides with the retreat of weaker hands.

The Net Unrealized Profit/Loss Index (NUPL) of short-term investors — indicating the profit or loss of short-term investors — has fallen to 0.21, the second lowest in a month. Traditionally, local lows of this index often signal recovery points when weaker investors withdraw and others hold onto smaller profits. For example, on August 19, when the NUPL was around 0.22, the price of Ethereum was $4,077. In the following trading sessions, ETH increased by nearly 20% to $4,829. The combination of buying power from whales and selling pressure from weaker holders creates an optimistic picture. Even if the price increases by 10% (, not 20% ) compared to the current level, it could bring ETH closer to testing new highs. Ethereum Price Levels and RSI Divergence Confirm Bullish Trend The third reason for the strong upward trend from the all-time high comes from the charts themselves. The daily price chart of Ethereum shows a hidden bullish divergence. While ETH is making higher lows, the Relative Strength Index ( RSI ) — which measures buying and selling momentum — is making lower lows.

This divergence is very important as it often signals the continuation of the trend. It indicates that selling pressure is gradually diminishing even as the price of Ethereum remains stable. The RSI divergence, when combined with the accumulation by whales, further reinforces the bullish trend. Regarding the price of Ethereum, the important resistance level to watch is $4,672 after surpassing $4,496. A complete breakout above this level will pave the way for the price to reach $4,958, and it is likely to explore even higher prices. The downside is the invalidation that occurs if ETH falls below $4,210, which would weaken the bullish trend.
