3 Altcoins To Watch In The First Week Of October 2025

As the month of October begins, the Q3 2025 is also set to begin which is usually a strong month for the crypto market. This is usually when the altcoin season starts to hype up and rather small and obscure coins pick up traction as well.

Given external factors majorly play into this growth, BeInCrypto has analysed three altcoins that the investors should be watching in the coming week.

Jupiter (JUP)

JUP’s price has recorded a steep 23% monthly loss, now holding at the $0.426 support level. The altcoin appears to be bouncing off this critical floor, but sustaining a recovery will require strong investor backing.

Investor optimism could return as Lending on the Jupiter exchange is set to launch this month. The introduction of this feature is expected to attract new capital and market participants, creating additional demand for JUP. This development could provide the catalyst needed for the token’s value to recover further.

With added investor interest, JUP price could climb toward $0.475 and potentially test $0.507. However, failure to breach these resistance levels may leave the altcoin consolidating between $0.475 and $0.426. 

Celo (CELO)

CELO is trading at $0.252 after suffering a 24% monthly decline, mirroring losses seen in JUP. The altcoin now sits dangerously close to its all-time low of $0.236, a level last tested three months ago, raising concerns about further downside risks if bearish pressure persists.

Celo is preparing for a major upgrade, with the Baklava and Alfajores testnets under Holesky scheduled for deprecation by the end of September. From then on, all testing and integrations will transition to Celo Sepolia, the new Ethereum Layer 2 testnet. This shift could boost developer activity and investor sentiment.

The upgrade may help CELO climb from $0.252 toward $0.267 and potentially $0.287 if bullish momentum strengthens. However, without supportive market conditions, CELO could fail to rally and instead drop back to its all-time low of $0.236, which would invalidate the short-term bullish outlook.

Onyxcoin (ONYX)

Onyxcoin is preparing for the launch of its long-awaited Goliath testnet, scheduled for late September or early October. The development has been in progress for months, and its rollout could be the catalyst needed to restore momentum.

The launch could help revive investor interest in XCN, which is trading at $0.0106 while struggling to maintain support above $0.0103. Despite recent weakness, Onyxcoin maintains a strong 0.77 correlation with Bitcoin, suggesting its price trajectory could closely mirror broader crypto market movements in the short term.

If Bitcoin continues to rise and the Goliath testnet delivers as expected, XCN could rally toward $0.0128. However, if bullish support fails to materialize, the altcoin risks slipping below $0.0103 and potentially falling further to $0.0095, which would invalidate the optimistic price outlook for Onyxcoin.
