3 Altcoins That Can Hit All-Time Highs In September 2025

The month of September could either continue the efforts of August of end up changing the direction altogether. When it comes to the altcoins, the biggest wait for the investors is a new ATH.

Thus, BeInCrypto has analysed three top coins that are holding strong and are also likely to reach a new all-time high in September.

Ethereum (ETH)

Ethereum is among the closest altcoins to retest its all-time high. Currently priced at $4,461, the altcoin leader is just 11% away from reaching its previous peak of $4,956. The proximity highlights Ethereum’s resilience and positions it as one of the top contenders for a breakout this cycle.

Sustained positive momentum will be critical for Ethereum to reach new highs. The Relative Strength Index shows bullish momentum remains, though it is close to slipping below the neutral line. If strength holds, ETH could breach $5,000 in September and establish a new all-time high for the asset.

If Ethereum loses momentum, the risk of decline grows. A fall through the neutral 50.0 RSI level would confirm bearish pressure. Such a move could drag ETH below $4,222, opening the possibility of a drop to $4,000 or lower, weakening its short-term bullish outlook significantly.

XRP

XRP is trading at $2.81, maintaining support above $2.74 at the time of writing. The altcoin’s ability to move toward its all-time high depends heavily on investor sentiment. Market participation will play a decisive role in whether XRP sustains momentum or faces pressure from renewed selling activity.

The Ichimoku Cloud indicates bullish momentum could be developing, offering a potential boost for XRP. This technical signal suggests favorable conditions for upward price action. If sustained, the altcoin may climb 29.8% to retest its all-time high of $3.66, a level that has remained unbroken since previous market cycles.

If investors remain cautious, XRP may struggle to hold its current position. A break below $2.74 would expose the token to additional losses. Continued selling pressure could push the price down to $2.54, weakening support levels and invalidating the bullish outlook that is currently forming for XRP.

Tron (TRX)

TRX remains one of the few cryptocurrencies still within reach of its all-time high despite being 32% away from $0.45. Tron’s recent 60% network fee reduction aims to attract more users and investors. This cost-cutting measure could provide the momentum needed to strengthen demand and drive price recovery.

The network upgrade may serve as a catalyst for TRX, enabling the altcoin to breach resistance levels at $0.34 and $0.37. However, sustained investor support will be critical if the cryptocurrency is to advance toward its previous peak of $0.45 and potentially establish a new all-time high.

If momentum fades, TRX risks slipping into decline. A breakdown below $0.33 support could send the token lower, targeting $0.32 or even weaker levels. Such movement would reduce the likelihood of TRX forming a new all-time high this month.
