In recent months, the crypto market has undergone a significant shift. While Bitcoin (BTC) and Ethereum (ETH) have remained relatively resilient—down only around 15% from their 2025 highs—many major altcoins have plunged dramatically. Assets like Solana (SOL), Avalanche (AVAX), Aptos (APT), and Sui (SUI) have seen corrections ranging from 40% to as high as 70%, sparking growing concern among investors and reshaping market sentiment.
This divergence raises a critical question: why are altcoins turning bearish despite BTC and ETH maintaining strong price levels? The answer lies in a combination of structural, economic, and behavioral factors unique to the broader altcoin ecosystem.
The Altcoin Downturn: A Closer Look
While BTC and ETH continue to benefit from institutional adoption and ETF inflows, altcoins face mounting pressure from multiple fronts. Unlike large-cap cryptos with deep liquidity and strong network effects, mid- and small-cap tokens are more vulnerable to supply shocks, weak demand, and seasonal trends.

SOL, once one of the best-performing assets in 2024–2025, is now down over 50% from its peak. Similarly, AVAX has retraced nearly half its value, while newer layer-1 blockchains like APT and SUI have shed up to 70%. These steep declines aren’t isolated—they reflect a broader trend of weakening confidence in speculative digital assets.
But what’s driving this sell-off?
Rising Token Supply and Dilution Pressure
One of the most underappreciated forces behind the altcoin slump is token dilution due to scheduled unlocks. Many projects released tokens with long vesting periods for team members, early investors, and ecosystem funds. Now, those periods are expiring—flooding the market with new supply.
Take Arbitrum (ARB) as an example. Despite its market cap increasing from $1 billion to $2.5 billion, the price of ARB has hovered near its lowest levels since September 2024. Why? Because a massive influx of unlocked tokens has overwhelmed demand.
Similarly, Solana adds approximately 75,000 new tokens to circulation every day—worth about $10 million at current prices. This constant emission creates persistent selling pressure, especially when there's no matching increase in buying interest.
Quinn Thomson, founder of Lekker Capital, highlighted this dynamic on X:
“Unlike traditional markets where ETF inflows or share buybacks create passive buying, crypto—especially altcoins—faces the opposite: continuous selling pressure from unlocks.”
Without strong organic demand or capital inflows, such supply waves naturally push prices down.
Venture Capital Exit Pressure
Another major driver is venture capital (VC) fund liquidation. Many VCs invested heavily in blockchain startups between 2021 and early 2022, just before the last bear market. Now, with those investments maturing and unlock schedules ending, funds face pressure to realize returns for their limited partners.
Markus Thielen, founder of 10x Research, noted that over $13 billion was invested by VCs in Q1 2022, right before crypto crashed. With artificial intelligence drawing investor attention and capital away from crypto, these funds are now under pressure to return profits—prompting them to offload their altcoin holdings.
This creates a self-reinforcing cycle:
- More selling → lower prices → weaker sentiment → reduced new investment → further price drops.
And because many altcoins lack diversified holder bases, even modest sell-offs can trigger sharp declines.
Lack of Fresh Capital Inflows
Even more concerning is the stagnation—or reversal—of new money entering the crypto space. One of the clearest indicators is the stablecoin supply trend.
According to TradingView data, the combined market cap of the four largest stablecoins—USDT, USDC, FDUSD, and DAI—grew by $30 billion earlier in 2025 but has plateaued since April. This suggests that traders aren’t bringing in fresh fiat capital to buy crypto.
David Shuttleworth, partner at Anagram, pointed out on X that exchange-based stablecoin balances have dropped by $4 billion, reaching their lowest level since February. That means not only is new money not coming in—existing capital may be exiting.

Shuttleworth added:
“The lack of incoming capital is particularly damaging for tokens facing large unlocks, new launches, or upcoming airdrops.”
This is evident in recent token launches:
- Wormhole (W): down ~65% from its all-time high
- Ethena (ENA): down ~70%
- Starknet (STRK): down ~60%
All three face multi-billion-dollar token distributions over the next few years—further weighing on investor sentiment.
Seasonal Trends: The June Slump
Historical patterns also play a role. Data from TradingView shows that June has historically been a weak month for altcoins. Over the past six years, the TOTAL3 index—which tracks the combined market cap of all cryptocurrencies except BTC and ETH—has declined every June.
So far in June 2025, TOTAL3 is already down more than 15%. This seasonality likely stems from reduced trading activity during summer months, especially in North America and Europe.
While not deterministic, this pattern reinforces downward momentum when combined with other negative forces.
FAQ: Understanding the Altcoin Bear Case
Q: Are BTC and ETH immune to these pressures?
A: Not entirely—but they’re far more resilient. Both benefit from strong institutional demand via spot ETFs, larger liquidity pools, and global recognition as digital commodities. This helps absorb sell-side pressure better than smaller-cap assets.
Q: Will altcoins recover?
A: Historically, altcoins have rebounded strongly during bull markets. However, recovery depends on renewed capital inflows, reduced unlock schedules, and improved market sentiment—none of which are immediate.
Q: Should I sell my altcoins now?
A: Investment decisions should be based on individual risk tolerance and portfolio strategy. However, understanding the structural headwinds—like dilution and VC exits—can help inform smarter timing and allocation choices.
Q: How can I identify altcoins less affected by unlocks?
A: Look for projects with transparent tokenomics, low circulating supply growth rates, and long-term vesting schedules already past major unlock events. On-chain analytics platforms can help track these metrics.
What’s Next for Altcoins?
The current environment is undoubtedly challenging for altcoin investors. With rising supply, falling demand, VC profit-taking, and seasonal weakness, the path to recovery won’t be quick or easy.
However, downturns also create opportunities. As weaker projects fade, stronger ecosystems with real usage—such as Ethereum layer-2 networks or high-throughput blockchains with growing dApp activity—may emerge stronger in the next cycle.

For now, patience and selectivity are key. While BTC and ETH act as anchors in uncertain times, altcoin investors must navigate a more complex landscape shaped by tokenomics, macro flows, and market psychology.
As always in crypto: risk management isn't optional—it's essential.
