From SUI to Remittix: Top Altcoins That are Showing Signs of High Volatility in October

Overview

  • SUI and EigenLayer may see extreme volatility due to large token unlocks.

  • Meme altcoins remain highly unpredictable, driven by social hype.

  • Remittix (RTX) emerges as a new speculative play in the cryptocurrency market.

The cryptocurrency market is showing signs of big swings. Bitcoin and Ethereum remain relatively steady, but many altcoins are entering a period of extreme volatility. Several factors are creating this unstable environment, including token unlock events, rising leverage in derivatives markets, new speculative trends, and uncertainty around regulation. These conditions often push altcoins, especially those outside the top two, into wild price movements.

Ethereum, for example, is trading near $4,181 with daily fluctuations between $4,088 and $4,233. Such numbers highlight that even large-cap assets are moving actively, and smaller altcoins with less liquidity are even more prone to sharper rises or falls.

Why Volatility is Increasing

Altcoin volatility does not happen in isolation. It is tied to specific drivers in the market. One of the biggest factors this month is token unlocks. When large batches of tokens are released into circulation, supply increases suddenly. If holders choose to sell, prices can fall sharply. On the other hand, if new buyers absorb the supply, rapid rebounds are possible.

Another factor is leverage. Open interest in altcoin derivatives has reached nearly $47 billion, which is a sign of aggressive betting on price moves. This high level of leverage means that even small shifts in price can trigger mass liquidations, sending prices either crashing or soaring in minutes.

Capital is flowing from safer coins into more speculative ones. Narratives such as artificial intelligence tokens, decentralized infrastructure projects, and meme-inspired coins are attracting attention. Altcoins tied to these themes are moving more sharply than established projects.

Finally, uncertainty in regulation and global economics is adding fuel. Interest rate expectations, legal decisions about crypto trading in the United States and Europe, and broader market swings are all influencing trader behavior. Whenever the outlook shifts, altcoins tend to react more violently than Bitcoin.

SUI: The Main Candidate for Sharp Swings

SUI is one of the most closely watched tokens at the end of September. A major unlock is scheduled for October 1, when 44 million tokens will be released. This represents more than 1.2% of its existing circulating supply, valued at roughly $138 million.

This type of event is almost guaranteed to create volatility. If a large portion of these tokens hits the market, selling pressure could drag prices down quickly. On the other hand, if buying demand is strong, a squeeze could follow, sending prices up in bursts. Either way, traders expect SUI to swing dramatically as September closes and October begins.

EigenLayer (EIGEN): Another Unlock Story

EigenLayer is another project about to experience turbulence. The platform has an unlock event of nearly 39 million tokens. As EigenLayer plays an important role in Ethereum’s restaking system, the token’s market movements will also influence broader staking discussions.

This combination of a big supply shock and a strong connection to Ethereum’s ecosystem means EIGEN is likely to be one of the most unstable altcoins in the final days of September. Price could fall if early investors exit, but equally, renewed confidence in staking rewards could spark buying interest.

ENA: Smaller Unlock, Big Impact

ENA is also approaching an unlock on October 2. While the scale is smaller compared to SUI and EIGEN, the market effect may still be dramatic. Smaller-cap tokens tend to move harder as there is less liquidity and fewer buyers to absorb sudden changes.

Even a moderate increase in supply could create exaggerated price reactions. For this reason, ENA is expected to join the list of highly volatile tokens at the end of the month.

Meme and Viral Tokens: The Wild Cards

Meme tokens have always been the most unpredictable corner of the market. Coins such as Maxi Doge, PEPENODE, Snorter Bot, and newer Shiba Inu spin-offs have shown daily price moves in double or even triple digits.

These tokens are not driven by fundamentals but by social media buzz and community hype. This makes them highly volatile, as sudden surges of attention can send prices soaring, while fading interest can lead to instant collapses. Toward the end of September, as traders look for quick profits, meme coins are likely to see huge swings.

Remittix (RTX): A Rising Speculative Bet

Remittix, a relatively new project, is drawing attention as a “PayFi” token focused on crypto-to-fiat transfers. Backing from major investors, upcoming listings on exchanges like BitMart and LBank, and strong narratives around cross-border payments are pushing it into the spotlight.

As Remittix is still young and has low liquidity, any sudden buying or selling will result in large price moves. Its potential upside is high, but so is the risk of sharp crashes. The coming exchange listings make RTX a token to watch for volatility as September ends.

Other Large-Cap Altcoins in Play

While smaller tokens are set to show the biggest moves, large-cap coins like XRP, ADA, and SOL should not be ignored. These coins are often more stable than meme tokens, but in times of market stress or big headlines, they can also swing dramatically.

Cardano and Ripple, for instance, are competing narratives for network adoption. Any positive or negative news about their ecosystems could cause price spikes or drops. Solana, with its reputation for speed and scalability, remains a trader favorite, and when momentum shifts, the price can surge or fall quickly.

The Influence of Speculative Narratives

Another area of volatility comes from tokens connected to hot narratives such as artificial intelligence, decentralized physical infrastructure networks, and data-sharing protocols. These sectors are attracting speculative inflows as traders bet on the next ‘big thing’ in crypto. However, most of these tokens are new and thinly traded, and their price action is unstable. Sudden announcements, partnerships, or even rumors can trigger wild moves.

What to Expect in the Final Days of September

Altcoin traders are expecting heightened swings during October. The most important things to watch include token unlock schedules, whale transfers to exchanges, changes in derivatives market positioning, and any unexpected regulatory announcements. Even macroeconomic data such as inflation reports or central bank speeches can have ripple effects on crypto prices.

Low-liquidity periods also matter. If trading volume falls, even small trades can cause major price jumps. Conversely, if volume spikes, momentum can carry tokens higher or lower than expected. Altcoins often follow Bitcoin and Ethereum’s overall direction. Any large move in the top two assets will likely spill over into the rest of the market.

The Outlook

Among the altcoins, SUI and EigenLayer appear to be the strongest candidates for extreme volatility thanks to their large unlock events. ENA also deserves attention, since smaller unlocks often hit thinner markets harder than expected. Meme coins like Maxi Doge, PEPENODE, and Snorter Bot will likely remain the most unpredictable, moving in line with social media chatter. Remittix adds another layer of uncertainty as a new project entering a speculative stage with upcoming exchange listings.

XRP, ADA, and SOL remain in the mix as potential surprise movers, particularly if global news or regulatory updates arrive. Meanwhile, tokens tied to popular themes like AI and DePIN could rally sharply on hype but fall just as quickly.

Volatility in altcoins is likely to remain high through the end of September 2025. The combination of unlock events, leveraged positions, narrative-driven rotations, and unpredictable macro events ensures that markets will not remain quiet. For investors and traders, the final days of the month will demand close monitoring and careful risk management, as swings in either direction could be rapid and severe.
