Why Are Altcoins Down? The Perfect Storm Behind Crypto's Performance Gap

The cryptocurrency market tells two very different stories right now. Bitcoin and Ethereum are weathering the storm relatively well, but altcoins are being battered. Tokens like Solana, Avalanche, Aptos, and Sui have plunged between 38% and 82% from their yearly highs—far exceeding the 22% to 17% declines in BTC and ETH respectively. For altcoin investors holding these assets, the pain is real. This isn’t just a correction; it’s a fundamental mismatch between supply pressure and capital availability that’s crushing smaller tokens while majors hold steady.

The Venture Capital Exit Squeeze

The roots of altcoin weakness trace back to a specific moment in crypto history: Q1 2022. That quarter saw venture capital funds pour $13 billion into blockchain projects. Then the market collapsed into a severe bear market, and VCs found themselves underwater on most investments for over two years.

Now, as markets have recovered and those investments have gained value, these funds face mounting pressure from their Limited Partners to realize gains and deploy capital into hotter sectors like artificial intelligence. The result? A coordinated liquidation wave. “Those funds are now under pressure from their investors to return capital,” explained Markus Thielen, founder of 10x Research. When thousands of institutional holders start unwinding positions simultaneously, there’s simply not enough retail demand to absorb the sales without prices collapsing.

This creates an asymmetric dynamic: Bitcoin and Ethereum benefit from broad institutional adoption and passive capital flows through products like spot ETFs. Altcoins, by contrast, depend on active trading demand that evaporates when sentiment turns negative.

The Chronic Dilution Problem

Beyond the VC exit wave, many altcoins face a structural headwind: relentless token supply growth. Most altcoin tokens are locked during initial distribution, held by early investors, earmarked for ecosystem development, or reserved for future grants. What this means is that as circulating supply increases dramatically over time, the tokens become increasingly vulnerable to price pressure.

Consider Arbitrum’s ARB token. Despite its market capitalization climbing to around $581 million, the token is hovering near its all-time lows because supply has expanded so dramatically. Similarly, Solana’s supply inflates by approximately 75,000 tokens daily—worth roughly $6.6 million at current prices. This represents thousands of tokens hitting the market every single day that need to find buyers.

The comparison to traditional assets is telling. “Unlike equities which have a constant passive bid from ETF inflows and bond buybacks, crypto, and in particular altcoins, have the opposite—a constant stream of sell pressure,” noted Quinn Thomson, founder of Lekker Capital. Bitcoin’s fixed supply tells a different story; Ethereum’s transition to proof-of-stake dramatically reduced inflation. Altcoins get no such relief.

Stablecoin Outflows Signal Liquidity Crisis

The third pillar of altcoin weakness is a sharp reversal in on-exchange liquidity. The combined market capitalization of the four major stablecoins—Tether (USDT), Circle’s USDC ($75.39 billion), First Digital’s FDUSD ($1.45 billion), and Maker’s DAI ($4.21 billion)—expanded by $30 billion earlier in 2025 but has been essentially flat since. More critically, stablecoin balances sitting on exchanges (the “dry powder” available for traders to deploy) have collapsed by $4 billion to their lowest levels since February.

This matters enormously because stablecoins are the gasoline that powers altcoin trading. “This has particularly bad implications for tokens with large upcoming unlocks as well as new tokens and airdrop programs,” David Shuttleworth, a partner at Anagram, warned. Newly launched tokens like Wormhole (W), which has crashed 85.79% from its yearly high, and Ethena (ENA), down 73.16% year-to-date, face billions of dollars worth of additional tokens hitting the market in coming years. Without fresh capital inflows, these tokens have virtually no buyers.

Even established Layer-1 challengers like Starknet, which has fallen 78.45% from peaks, are being crushed by the combination of upcoming unlocks and absent liquidity.

Seasonal Patterns Compound the Pain

History provides an uncomfortable truth for altcoin holders: June has been a consistently brutal month for smaller tokens. Analyzing the past six years of data, the aggregate market cap for altcoins excluding Bitcoin and Ethereum (tracked by the TOTAL.3 metric) has declined every single June. There’s no obvious fundamental reason—it’s simply a seasonal pattern in trading behavior that disadvantages speculative assets when broader market sentiment weakens.

The pattern is repeating. With thin trading volumes and diminished appetite for risk, altcoins lack the resilience to weather technical selling pressure.

The Recovery Question: Can Momentum Shift?

Recent price action has introduced some hope for beaten-down altcoins. Bitcoin rebounded sharply to near $69,000 in a squeeze that pulled along major altcoins, creating a technical bounce. However, this rebound appears driven primarily by short-covering and thin-liquidity mechanics rather than by fundamental improvements. LMAX Group’s Joel Kruger cautioned that the rally’s durability remains questionable without sustained buying pressure through key resistance levels.

For altcoins specifically, the path to meaningful recovery requires either a significant new inflow of capital to exchanges (visible through rising stablecoin balances), a dramatic slowdown in token unlocks, or a fundamental shift in sentiment toward riskier assets. Some funds are indeed rotating into volatile altcoins and options strategies, but this appears speculative rather than conviction-driven.

The gap between Bitcoin’s modest 22% annual decline and Solana’s 38% fall—or Aptos’ 82% collapse—won’t close until the underlying dynamics change. Token supply will keep growing. Venture funds will keep selling. And without fresh capital arriving to exchanges, altcoins remain structurally vulnerable. That’s why altcoins continue to struggle while Bitcoin and Ethereum hold relatively steady: it’s not about the direction of the market, but about the specific pressures bearing down on different cryptocurrency categories.
