3 Altcoins that have the potential to reach new highs in September 2025

September may continue the trend from August, or conversely, open up a completely new direction for the market. For altcoins, what investors are most looking forward to is the formation of new all-time highs (ATH).

Bitcoin Magazine has analyzed 3 prominent altcoins that are maintaining their position and have the potential to establish ATH in September.

Ethereum (ETH)

Ethereum is currently the altcoin closest to retesting its previous peak. With a price of $4,355, ETH is only about 13% away from its ATH of $4,956. This short distance indicates the persistent strength of Ethereum, making it a strong candidate for a breakout in the current cycle.

Maintaining positive momentum will be very important for Ethereum to reach new highs. The Relative Strength Index (RSI) indicates that the upward momentum is still present, although it is close to slipping below the neutral line.

If buying power is strong enough, ETH could surpass the $5,000 level in September and establish a new ATH for this asset.

This move could pull ETH below $4,222, opening up the possibility of sliding back to $4,000 or lower, significantly weakening short-term bullish prospects.

XRP

XRP is trading at $2.79, maintaining support above $2.74 at this time. The ability to reach the ATH of this altcoin depends heavily on investor sentiment.

Market participation will play a decisive role in whether XRP can maintain its upward momentum or face pressure from new sell-off activities.

The Ichimoku Cloud indicates that a bullish momentum may be developing, providing potential support for XRP. This technical signal suggests favorable conditions for upward movement. If maintained, this altcoin could increase by 29.8% to retest the ATH level at $3.66, a level that has not been broken since previous market cycles.

Selling pressure could pull the price down to $2.54, weakening support levels and invalidating the bullish outlook that is forming.

Tron (TRX)

TRX is still one of the few altcoins that remains in a growth trajectory, despite being approximately 32% away from the ATH at $0.45. Recently, Tron has reduced network fees by 60%, a move aimed at attracting more users and investors. This could be a crucial catalyst for increasing demand and supporting price recovery.

The network upgrade could act as a catalyst for TRX, helping this altcoin break through resistance levels of $0.34 and $0.37. However, sustained support from investors will be crucial if TRX wants to move towards the previous peak at $0.45 and potentially establish a new ATH.

Dropping below the support level of $0.33 could lead the altcoin to a sharp decline, returning to $0.32 or even lower. Such volatility would decrease the likelihood of TRX reaching a new ATH this month.
