Top five altcoins worth buying in October 2026: These currencies may be about to soar

为什么2026年10月是山寨币的大月？

在连续三周上涨后，比特币重新站稳86,000美元上方。现货ETF刚刚录得第三周的净流入，而疲软的9月就业报告使得美联储10月加息的预期落空。这正是山寨币市场喜欢的背景：稳定的比特币、更宽松的货币预期，以及一个开始将目光从“老大”身上移开、寻找下一个增长点的市场。

资金轮动已经开始。Quant在被The Clearing House选中用于代币化存款结算后，一周内暴涨超过300%；AAVE在月初的前三天从约159美元飙升至180美元以上；Sui则在Basecamp大会前正逼近阻力位。然而，追逐已经翻了三倍的币种是快速亏损的捷径，因此本列表聚焦于五种具有流动性、催化剂明确指向10月且价格仍远低于历史新高的山寨币。

以下是2026年10月值得关注的五大山寨币（截至10月5日的当前价格）：

1. 以太坊 (ETH)：Glamsterdam升级是否是以太坊所需的催化剂？

以太坊今日价格：约2,720美元

以太坊周一以2,727美元开盘，目前交易价位略低于该水平，较周日上涨约1.5%。尽管以太坊在第三季度跑赢比特币，但它在2,800美元附近已被拒绝三次，因此图表处于蓄势待发状态，等待突破的理由。

This reason has a clear date. Glamsterdam, the largest Ethereum upgrade since the merger, will be tested online in Sepolia on October 6, with a main network target of the fourth quarter of 2026. This upgrade includes two major features: one is to "establish a proposer and builder separation mechanism"(EIP-7732), which incorporates block construction into the protocol layer and reduces reliance on MEV-Boost middleware; the other is "block-level access list"(EIP-7928), which allows clients to process transactions in parallel. The Ethereum Foundation said that the lower gas limit after the fork would support 200 million yuan, more than three times the current capacity.

Add in the growing tokenization pipeline (ARK has just launched tokenized fund shares on Ethereum via Securitize) and the continued supply of spot ETH ETFs, and you get the only one of the large-cap tokens with a hard-planned event this month. The risk lies in the cliché: the upgrade schedule could be delayed, and if the Sepolia fork is chaotic, it could push the main online launch time and narrative into 2027.

Focus: The daily line closed firmly above US$2,800. If it falls below US$2,600, the breakthrough logic will be temporarily shelved.

2. Solana (SOL): Can Solana recover $150 after a 60% discount?

Solana Today's price: About US$121

Solana was trading at about $121, up about 2% on the day, but still nearly 60% below its all-time high of $295. This gap is at the core of its investment logic. Solana is one of the few networks whose ecosystem continues to grow while token prices stagnate: Decentralized Exchange (DEX) trading volume remains at the forefront of cryptocurrencies, consumer applications continue to be launched, and at the end of August, Charles Schwab added SOL trading to its 39 million customers, tying with Avalanche and Chainlink.

Although there is a spot Solana ETF, its inflows have cooled, which is why the rebound has stagnated around $120 for several weeks. Note the special situation for European readers: SOL rises throughout the year in euros and falls in dollars, so your entry currency is more important than ever.

Solana does not have a single hard date catalyst like Ethereum. Its case lies in cheap Beta gains as a revival of widespread altcoins and supported by the strongest on-chain activity in any large alternative Ethereum network. If funds are withdrawn from Bitcoin, SOL has historically been the first and most violent currency to react.

Focus: ETF capital flow turned positive again, and the weekly closing firm above US$130. Support is around $109, the level at which SOL rebounded in late September.

3. Chainlink (LINK): Is Chainlink the best tokenization target in 2026?

Chainlink Today's price: About US$11.40

Chainlink has moved slightly higher recently, trading close to $11.40 after consolidating in the $8 to $9 range throughout most of the summer. Among the five currencies, LINK has the strongest institutional story and the weakest price trend, which is exactly the combination that contrarian investors are looking for.

Background: Chainlink is the infrastructure behind tokenized finance. Its network now includes data providers such as the U.S. Department of Commerce, Standard & Poor's Global Ratings, FTSE Russell, Deutsche Börse and Tradeweb; it has signed an agreement with SIX Group of Switzerland; and CCIP 2.0 adds compliance and configurable settlement capabilities that banks require before transferring real assets across chains. Charles Schwab decided in August to list LINK on his platform, making it available to a mainstream U.S. broker audience for the first time.

The well-known trap is that network adoption rates and token prices have been decoupled over the years. LINK needs the tokenization boom to be reflected in fee revenue and pledge needs, not just press releases. With Bitcoin stabilizing and Quant's transactions reminding people that banks are actually clearing tokenized deposits online, October is a good time to close the gap.

Focus: $12 is the level at which LINK has failed repeatedly. An effective breakthrough would open the door to $13 to $14; if it fell below $10.20, it would return to summer range.

4. Sui (SUI): Can Sui Basecamp push SUI above $1.30?

Sui Today's price: About US$1.23

Sui is the trend choice this time. SUI traded close to $1.23, rising about 5% in 24 hours and more than 60% in a month after strong support areas drove its 80% gain. It is still 77% below the historical low of $5.37, so there is still room to rise, but it is also the most overbought currency on the chart in this list.

The catalyst is just two days later. Sui Basecamp 2026 will be held at the Marina Bay Sands Hotel in Singapore on October 7th and 8th, and Mysten Labs has been promoting its next plans: global payments, stablecoins and AI proxy transactions. The data supports this argument. The Sui Foundation said that since August 2025, the network has processed more than US$1 trillion in stablecoin transfers. USDsui was launched in March through Stripe's Bridge as a local dollar for payment apps, and the Hashi protocol recently enabled Bitcoin to be used as collateral on Sui, triggering the latest wave of gains.

Two considerations. A batch of tokens were unlocked on October 3, which has been absorbed by the market, but there are more unlocking plans in the future, and SUI has the habit of selling after the meeting ends and the announcement is priced. Buying Basecamp is a deal, not long-term investment logic, unless DeFi's Total Locked Value (TVL) can eventually keep up with the payment size.

Focus: $1.27 is the immediate obstacle, and $1.34 is the key. If it is rejected here and closes below $1.10, it means that the hype caused by Basecamp has subsided.

5. Aave (AAVE): Why did whales buy Aave in October 2026?

Today's price of Aave: About US$180

Aave is DeFi's first choice, starting in October with the strongest on-chain signal of any blue-chip protocol token. AAVE was trading close to $180, climbing from about $159 on October 1, and a positive line of 13.8% appeared on October 3. It is about 73% below its all-time high of $670, with a hard supply cap of 16 million tokens, of which more than 96% are in circulation. There is no unlocking selling pressure here.

The interesting part is who is buying. Holding 100,000 to 1 million AAVE addresses has added approximately 190,000 tokens since September 28, worth approximately $30 million. Weighted sentiment turns positive as prices rise, rather than lagging behind. Thanks to the recovery of Bitcoin and the fading of expectations for a Federal Reserve interest rate hike, renewed DeFi lending activity is boosting agreement revenue. Aave remains the largest lending market in the crypto space, so when DeFi wakes up, money flows first to AAVE.

The risk lies in correlation. A sharp correction in Bitcoin will trigger liquidations in the lending market, and AAVE tends to fall harder than ETH at these moments. The token has doubled since July, so the cooling-down period between $160 and $180 will be healthy rather than worrying.

Focus: Holding on to US$170 can maintain the upward trend. A breakthrough of $200 will be the first time since spring and is likely to drive the rest of the DeFi sector.

Which altcoins should you first buy in October 2026?

If you only choose one,Ethereum is the anchor point: maximum market value, clear catalyst, and minimum unexpected risk. Solana and Chainlink are recovery targets for investors who believe that the next wave of the cycle will reward fundamentals that have been ignored by prices. Sui and Aave are trend names that are suitable for small positions configured and observed daily.

Explanation of missing content: Quant, XRP and Avalanche also have October stories. Quant was excluded because a 300% weekly gain was not the entry point, and XRP at around $1.39 lacked a specific catalyst for the month. They should all be on the watch list.
