Why September could open a buying opportunity for Ethereum

Ethereum’s price was rejected at the $5,000 level in August. Profit-taking pressure at resistance has slowed bullish momentum. However, it has not stopped investors from expecting higher returns.

Is buying Ethereum in September and aiming for profits in the final quarter of 2025 realistic? Analysts point to several data points and forecasts.

Why selling pressure could continue in September but turn into an opportunity

CryptoQuant data shows Ethereum’s Cumulative Net Taker Volume dropped below -$2.4 billion.

This metric tracks trader sentiment and behavior on Binance. Takers are traders who place market orders, consuming existing liquidity. A negative Net Taker Volume means market sell orders dominate, signaling bearish sentiment.

At the same time, Binance Open Interest fell from over $11 billion to nearly $9 billion in August. This decline reflects reduced exposure to ETH.

The bearish mood could carry into September, slowing Ethereum’s rally or lowering the price.

Validator Queue data adds more pressure. As of August 27, 2025, the ETH unstake queue reached a record 986,408 ETH, with a waiting time of 17 days and 3 hours. Such a backlog could trigger heavy selling in September.

The queue continually growing like this means there are net new holders every day waiting to exit. Not a great sign,” investor Grubles noted.

History offers hope for September buyers

CoinGlass data on ETH’s monthly returns shows September has historically been weak. Since 2016, the average return has been -6.42% with a median of -12.55%.

In contrast, the fourth quarter has consistently been Ethereum’s strongest period. Average returns stand at +4.77% in October, +7.88% in November, and +6.85% in December. Across all Q4s since 2016, ETH has delivered an average return of more than 23%.

Overall, current signals suggest September could be a temporary storm. That dip might open a chance to buy ETH at lower levels. With Q4’s strong historical performance and potential recovery after unstaking, Ethereum could break new highs by year-end.

From a technical view, investor Axel Bitblaze expects Ethereum to follow a bullish megaphone pattern through the end of the year. He predicts a September correction could send ETH down to $4,200 before a surge toward $6,800 in Q4.

ETH broke a 4 year bullish megaphone, retested clean, and the structure points to $6,800 – $7,000 next." - Investor Axel Bitblaze predicted.

Still, risks remain. The Federal Reserve’s interest rate decision on September 17 may complicate market moves. A rate cut could support risk assets like ETH. But holding rates higher would intensify selling pressure.
