Key Takeaways
As September 2025 draws to a close, the crypto market looks set to finish on a strong note, with the total market cap edging back toward $4 trillion.
Yet, the month was a mixed bag for altcoins — some delivered explosive new highs, while others struggled to keep up.
With October just two days away, market watchers are turning their attention to history. Traditionally, October has been one of the most bullish months for crypto.
In this analysis, CCN spotlights three altcoins that could break into new all-time highs in October 2025, outlining the key drivers behind their momentum and the price targets they might reach.
To start the list of altcoins that could reach new all-time highs in ASTER. At press time, the token trades at $1.92, down about 20% from its Sept. 24 all-time high of $2.24.
One of the key reasons behind Aster’s explosive rally has been the bullish sentiment surrounding perpetual decentralized exchanges (DEXs).
Backing from Yzi Labs (formerly Binance Labs) added even more fuel, while public support from Changpeng “CZ” Zhao amplified the hype.
Looking ahead to October, ASTER looks well-positioned as one of the altcoins to test new all-time highs. In a recent X Space, CZ expanded on the project’s mission, revealing that ex-Binance employees hold stakes in Aster.
He also clarified that Aster is designed to compete with Binance directly rather than Hyperliquid, though he emphasized that it still indirectly supports the BNB ecosystem.
“Few understand this. Aster competes with Binance, but helps BNB,” CZ wrote on X.
From an on-chain perspective, Aster’s momentum looks even stronger. According to DeFiLlama, the project’s perpetual DEX volume has surged past $225 billion in the last seven days.
Sustained demand at this scale also strengthens the case for ASTER’s price to retest its previous all-time high.
From a technical perspective, the 4-hour chart highlights a bullish setup for ASTER. The token has carved out a double bottom pattern that aligns with the horizontal support of a descending triangle.
Furthermore, ASTER has broken above the triangle’s upper trendline. Meanwhile, the Chaikin Money Flow (CMF) has crossed above the zero line, showing that capital inflows are returning and buyers are regaining control.

If momentum holds, Aster could break the $2.42 resistance at its previous all-time high and rally toward $3.61 by October 2025.
However, if next month brings low demand and thin liquidity, the bullish setup may fail. In that scenario, ASTER risks sliding back to $1.26.
Another altcoin with sights set on a new all-time high in October is Mantle (MNT), the native token of Ethereum’s layer-2 project. MNT has surged nearly 50% this month alone, leaving it just 8% shy of its record peak.
Rising buying pressure fueled the September rally, and the daily chart now shows a bullish flag pattern. At press time, MNT tests the flag’s upper trendline, a breakout zone that could determine its next big move.
If the breakout is validated, MNT may breach resistance at $1.91. From there, momentum could drive the token toward a fresh all-time high at $2.75.

Conversely, if selling pressure builds, Mantle could struggle to clear resistance. In that scenario, the token risks sliding back toward $1.39.
Closing out the list is ApeX (APEX), the native token of the ApeX protocol, another fast-rising perpetual DEX. At press time, APEX trades at $2.27, marking a staggering 762% gain in the past seven days.
Much of this momentum comes from the bullish sentiment surrounding perpetual DEXs, which has fueled demand for rivals like Aster. But APEX has carved its own narrative as well.
On Sept. 28, the protocol announced it would soon launch a buyback program, which will begin in the coming days.
“Beginning next week, 50% of ApeX Protocol’s daily revenue will be allocated to repurchase APEX tokens from the open market combined with the $12,000,000 committed. Over time, this allocation will gradually increase, reaching up to 90% of all revenue,” The project disclosed.
Such initiatives often signal team confidence, reduce circulating supply, and intensify demand pressure — a combination that could drive APEX to fresh all-time highs in October.
At press time, APEX is 40% away from reclaiming its all-time high set a year ago. On the 4-hour chart, the Awesome Oscillator (AO) is positive, signaling that bullish momentum is building.

If this strength continues, APEX’s price could break above $2.71, clearing the way for a rally toward a new all-time high at $4.27.
However, the bullish case depends on the momentum being steady. If it fades, the token risks a pullback, with downside targets near $1.75
