Here Are 2 Altcoins Gaining Momentum as Market Optimism Returns

While Bitcoin remains relatively stable, two assets — Sei (SEI) and Arbitrum (ARB) — are now standing out with strong fundamentals and emerging technical signals that could define the next wave of market rotation.

Sei’s Meteoric Rise in User Activity

Sei Network continues to make headlines as one of the fastest-growing blockchains in the world. The latest on-chain metrics reveal 12.9 million monthly active addresses, propelling Sei to #6 globally and placing it ahead of well-established players such as Bitcoin (10.4M), Base (9.6M), and Ethereum (8.3M). This growth, nearly 200% since mid-2025, underscores the network’s accelerating adoption as developers and users flock to its high-speed, low-cost environment.

At the same time, Sei’s economic efficiency is proving to be a major competitive advantage. According to data from RR² Capital, the network boasts the lowest average transaction fee among top chains — just $0.0004 per transaction.

By comparison, Ethereum and Bitcoin sit at $5.70 and $5.50 respectively, while Solana averages $0.04. Such scalability and affordability have helped push Sei’s cumulative trading volume past $138 billion, showing that activity isn’t just growing — it’s being sustained by real user engagement.

From a market perspective, Sei’s token has reacted positively to this momentum. After confirming a buy signal on the daily chart, SEI’s price jumped more than 30%, currently trading around $0.183 with a market capitalization of $1.14 billion. Technical indicators such as MACD and RSI suggest bullish continuation, with traders eyeing a potential breakout above $0.20, which could mark the beginning of a broader mid-term uptrend.

Prominent market analyst Michaël van de Poppe also weighed in on Sei’s price structure, noting that the token is holding a crucial level of support that could mark the start of a stronger trend. He emphasized that altcoins appear to be bottoming at higher timeframe supports, and Sei’s resilience in this zone aligns with that broader pattern.

Van de Poppe stated that Sei remains part of his altcoin portfolio, highlighting his confidence in its long-term outlook. His chart analysis suggests that a break above key resistance could trigger a new upward leg, potentially aligning with the on-chain growth momentum currently driving network activity.

Arbitrum’s Liquidity Grab and Recovery Setup

Arbitrum (ARB) is also seeing renewed investor interest after months of sideways trading. Analysts from BitcoinSensus described its recent price action as a “liquidity grab and reclaim” pattern — a classic setup where the market sweeps lower levels to absorb liquidity before reversing upward.

The move has put ARB back on traders’ watchlists as it now targets the $0.62 resistance zone.

Adding to this bullish narrative, CryptoBusy highlighted a textbook Wyckoff accumulation pattern forming on the daily chart. This pattern typically marks the final stages of market manipulation and consolidation before smart money begins accumulating positions.

On-chain data further supports this thesis, with top wallets increasing their ARB exposure, suggesting confidence in long-term recovery.

Currently, Arbitrum trades near $0.295 with a market capitalization of $1.62 billion and 24-hour volume exceeding $176 million. Technical indicators are starting to stabilize, with RSI hovering around 44, hinting at strengthening momentum. Should buying pressure continue, analysts expect a breakout toward $0.40 in the short term, potentially opening the path to reclaiming the summer highs above $0.60.

Michaël van de Poppe also identified a bullish setup for Arbitrum, pointing to a strong bullish divergence and a clear bottoming pattern forming on higher timeframes. He described ARB as one of the most promising Layer-2 projects within the Ethereum ecosystem, with potential for a major rally once market sentiment strengthens.

According to van de Poppe, Arbitrum could outperform Bitcoin by up to 200% if momentum follows through, citing growing on-chain activity and deep accumulation signals. He views the current range as an opportunity to accumulate before the next wave of upside movement begins.

Momentum Returns to the Altcoin Market

The simultaneous strength seen in Sei and Arbitrum reflects a broader shift in market sentiment as traders rotate capital from Bitcoin and Ethereum into high-performance ecosystems. Sei’s explosive on-chain activity demonstrates growing adoption of next-generation infrastructure, while Arbitrum’s pattern of accumulation may signal a comeback for Layer-2 networks after months of underperformance.

As macro uncertainty eases and liquidity improves, both SEI and ARB stand out as altcoins capable of leading the next phase of market recovery — one powered by real usage, scalability, and a surge in investor confidence.
