Three Whale-Approved Altcoins to Buy Before October 2025

Crypto whales are placing big bets—and retail investors are scrambling to follow the money trail.

These institutional players move markets with single transactions, making their portfolio choices worth watching as we approach October's volatility window.

BNB: The Exchange Titan

Binance's native token continues defying regulatory headwinds. The platform's massive user base creates built-in demand—while its burn mechanism steadily reduces supply. Whales accumulate during dips, betting on the ecosystem's long-term resilience.

Ethereum Killer or Complement?

Smart contract platforms beyond ETH are attracting serious capital. Look for projects with actual developer activity rather than empty hype. Whale wallets don't lie about where real utility is building.

DeFi's Dark Horse

One under-the-radar protocol keeps appearing in whale transaction data. Its tokenomics reward long-term holders while punishing quick flips—exactly the kind of structure big players love before major market moves.

Timing matters more than picks in crypto. Whales position early, leaving retail investors to chase pumps. October traditionally brings volatility—whether you're riding waves or getting wrecked depends entirely on your entry point. Remember: the 'smart money' made fortunes while traditional finance was still arguing about whether Bitcoin was a passing fad.

Crypto whales, often seen as the “smart money” in digital assets, have been loading up on select altcoins during the recent market pullback. Their activity gives a glimpse into where major capital may FLOW next. With October shaping up to be a critical month for crypto, here are three altcoins that whales are quietly accumulating.

Ethereum (ETH): Buying the Dip

Ethereum has slipped below $4,000, marking a 14% decline in the past month. Despite the weakness, whales are accumulating aggressively. Over 406,000 ETH, worth more than $1.6 billion, has been added to whale wallets in recent days.

Ethereum’s fundamentals remain strong. Transaction fees are falling, and developers continue to improve the network. Some market leaders even compare ETH’s future trajectory to Bitcoin’s early growth. Tom Lee’s firm Bitmine has accumulated nearly $9 billion worth of ETH. Whales view the current dip as a buying opportunity ahead of potential upside later in the year.

Aster (ASTER): Backed by Binance

Aster, a new entrant in the perpetual DEX space, launched on September 17 and has already surged over 240%. Supported by Binance and CZ, Aster is seen as a challenger to Hyperliquid’s dominance.

In just two days, whales purchased more than $48 million worth of Aster tokens. Backing from Binance gives the project credibility and resources, which could fuel long-term growth. If Aster captures even a fraction of Hyperliquid’s market, its price could multiply several times from current levels.

Plasma (XPL): Backed by Big Names

Plasma (XPL) is a stablecoin-focused LAYER 1 blockchain that launched only days ago. Despite being new, it has attracted strong whale activity. Backers include Bitfinex and billionaire Peter Thiel’s Founders Club, adding weight to the project.

XPL has already risen from $0.70 to $1.21 since launch. One whale secured over $2.7 million worth of tokens during the public sale, while others accumulated at just $0.05. Even Justin Sun of TRON fame jumped in, making a quick $16 million profit from trading XPL. While still highly speculative, the project’s strong backers and whale interest make it one to watch closely.
