3 Altcoins To Watch In The Fourth Week Of September 2025

The past few days have been murky for the crypto market as Bitcoin has been declining and altcoins have been unable to find a path. Thus, the coming week will likely see altcoins dependent on external developments to find catalysts.

BeInCrypto has analyzed three such altcoins that are important to watch in the coming week.

Aster (ASTER)

ASTER price surged by 64% within 48 hours, making it one of the week’s top-performing altcoins. Currently trading at $1.45, ASTER’s momentum highlights rising investor interest. 

For ASTER to reclaim its all-time high of $1.99, the altcoin must first breach resistance levels at $1.59 and $1.87. If ASTER secures these levels as support, bullish sentiment may drive the token toward new highs in the near term.

However, ASTER faces downside risks if investors begin booking profits. A pullback below $1.39 support would expose the token to further losses, potentially dragging it down to $1.17. Such a decline would weaken confidence and invalidate the bullish thesis, delaying any recovery attempts.

Jupiter (JUP)

JUP’s price declined by 5.2% in the last 24 hours and is now trading at $0.498. The altcoin slipped below the $0.507 support but remains above its two-month uptrend line. Holding this line is crucial for maintaining bullish sentiment and preventing further downside pressure.

A 53.47 million JUP token unlock worth $26.71 million is scheduled this week. Historically, token unlocks increase selling pressure as supply outweighs demand. If the same occurs with JUP, the altcoin could lose strength and slip toward the $0.475 support.

However, strong demand ahead of unlocking could offset the negative effects. If buying momentum builds, JUP price could stabilize above $0.507, preserving its bullish structure. This would invalidate the bearish thesis and provide JUP with breathing room to consolidate.

Artificial Superintelligence Alliance (FET)

FET price dropped 8.4% this week, currently trading at $0.604. The altcoin remains in focus after 21Shares launched its Artificial Superintelligence Alliance AFET ETP, a move that could influence investor sentiment and potentially provide FET with momentum to stabilize after its recent decline.

The launch may serve as a catalyst for recovery, helping FET reclaim lost ground. If the token flips $0.612 into support, it could advance toward $0.637. Sustained bullish momentum would then allow the altcoin to push higher, with a possible move toward $0.663 on the daily chart.

However, failure to attract buying pressure from this launch could worsen losses. If momentum stalls, the FET price risks sliding further, potentially dipping to $0.590. A deeper decline could send the altcoin to $0.573, invalidating the bullish thesis.
