Altcoins 2025: Will They Run, or Is It Over for Them?

The crypto market is known for its cyclical nature. There are times when Bitcoin dominates, followed by periods where altcoins take the spotlight. In 2021, Bitcoin’s dominance played a significant role in shaping the market cycle, and in 2025, we’re seeing striking similarities. These parallels have led many investors and analysts to wonder whether an altcoin season is just around the corner.

Bitcoin dominance (BTC.D) refers to Bitcoin’s market capitalization relative to the total crypto market. When Bitcoin dominance rises, it indicates capital is flowing into Bitcoin rather than altcoins. On the flip side, a decrease in BTC.D can mean altcoins are gaining traction, often signaling the start of an “altcoin season.” This article will delve into the current state of Bitcoin dominance in 2025, how it compares to 2021, and whether an altcoin rally is on the horizon.

Bitcoin Dominance in 2021: A Breakdown

At the start of 2021, Bitcoin dominance was approximately 70%. However, as the year progressed, it began to drop rapidly. Several factors contributed to this decline:

• Altcoin Boom: Altcoins such as Ethereum, Binance Coin, and Solana saw massive price increases, shifting investor focus away from Bitcoin.
• DeFi and NFTs: The rise of decentralized finance (DeFi) and non-fungible tokens (NFTs) caused investors to look more towards Ethereum and other alternative layer-1 blockchains.
• Institutional Adoption: Initially, institutions were mostly interested in Bitcoin. However, many began exploring Ethereum and other smart contract platforms as the year went on.
• Market Cycles: Historically, Bitcoin leads the market. However, after reaching a peak, altcoins typically rally as investors seek higher returns.

By mid-2021, Bitcoin dominance had dropped to around 40%, marking one of the most significant altcoin seasons in history. During this period, many altcoins saw substantial gains, outperforming Bitcoin in percentage growth.

Bitcoin Dominance in 2025: The Resurgence

Fast forward to 2025, and Bitcoin dominance has once again taken center stage. After a prolonged bear market in 2022 and 2023, Bitcoin began to regain dominance, reaching about 61% by early 2025. Many alts and memes have been bleeding hard, including hot shiny new ones like Fartcoin which saw a 70% retrace. This resurgence of BTC.D mirrors what happened in 2021, leading many to speculate on what’s next for altcoins.

Key Factors Contributing to Bitcoin’s Dominance in 2025:

• Spot Bitcoin ETFs: The approval of Bitcoin exchange-traded funds (ETFs) has led to more institutional investment in Bitcoin.
• Regulatory Clarity: With improved regulatory frameworks, Bitcoin has become the preferred asset for conservative investors.
• Macroeconomic Factors: Economic uncertainty and inflation have reinforced Bitcoin’s narrative as “digital gold.”
• Bitcoin Halving: With the Bitcoin halving event scheduled for April 2024, the reduced supply of Bitcoin has contributed to price appreciation and dominance.

Despite these factors, Bitcoin dominance appears to be stalling, raising questions about whether an altcoin season is just around the corner.

Is an Altcoin Season on the Horizon?

Historically, altcoin seasons have been triggered when Bitcoin dominance reaches a resistance level and begins to decline. In 2021, BTC.D faced resistance around 60-65% before reversing. In 2025, a similar pattern is emerging.

Several indicators suggest that an altcoin season may soon take place:

• BTC.D Resistance Level: Bitcoin dominance is currently testing historical resistance levels, just as it did before the altcoin boom in 2021.
• Increased Development in Altcoins: New projects, including layer-2 solutions, artificial intelligence (AI) blockchain, and interoperability protocols, are gaining traction.
• Ethereum ETF Possibilities: If an Ethereum ETF gets approved, it could reignite interest in altcoins.
• Retail Investor Sentiment: During bull runs, retail investors tend to shift from Bitcoin to altcoins, seeking higher returns.

Expert Opinions on Bitcoin Dominance and Altcoin Season

Bullish on Altcoins

Many analysts are optimistic about the potential for an altcoin season. Crypto strategist Michaël van de Poppe believes Bitcoin dominance will soon drop, leading to a massive altcoin rally. He points to altcoin narratives, such as AI and gaming tokens, which are gaining momentum.

Similarly, analyst Benjamin Cowen predicts that Bitcoin’s dominance could fall to 50% or lower if capital begins flowing into altcoins. He highlights the strengthening position of Ethereum and the rise of alternative layer-1 and layer-2 networks as key factors.

Cautious Approach

Some analysts remain cautious, suggesting that an altcoin season may not fully materialize until Bitcoin dominance hits 70% or higher. Market analyst Rekt Capital warns that while altcoins may experience short-term surges, a true altcoin season might take longer. He emphasizes that institutional capital is still primarily focused on Bitcoin and Ethereum.

Comparing Market Conditions: 2021 vs. 2025

Funds Moving to Stablecoins Instead of Altcoins

A significant trend noted by crypto analyst Ali Martinez is the flow of capital into stablecoins instead of altcoins. This shift reflects a more cautious stance among investors, as they seek stability through assets like Tether (USDT) and USD Coin (USDC).

Since Donald Trump’s election win, stablecoin supply has surged significantly. Tether’s supply has grown by $20 billion to $140 billion, while USD Coin’s supply has increased by $17 billion to $52 billion. These shifts suggest that investors are waiting for more favorable conditions before diving back into the altcoin market. With stablecoins now an integral part of the global economy, liquidity could soon flow back into the crypto space.

Ethereum’s Struggles

Ethereum has traditionally played a central role in driving altcoin seasons. However, ETH has faced some significant challenges recently. Its price has remained stagnant, and traders have begun to focus more on other Layer-1 projects and speculative tokens. Without Ethereum leading the charge, altcoins are struggling to capture the same level of attention and capital.

Crypto trader Picolas Cage argues that for altcoins to recover, Ethereum needs to see a price rebound. Without ETH’s leadership, the altcoin market may remain in a holding pattern, waiting for a catalyst that could trigger a shift.

Potential Risks and Challenges

While there are many indicators pointing toward an altcoin season, risks remain:

• Bitcoin Rally Continues: If Bitcoin’s uptrend persists, it could continue dominating the market, delaying altcoin growth.
• Regulatory Uncertainty: Stricter regulations on DeFi, stablecoins, or altcoin projects could slow down adoption.
• Macroeconomic Factors: A global recession or financial crisis could hinder speculative investments like altcoins.
• Security Concerns: Hacks and exploits in DeFi protocols or major altcoin networks could reduce investor confidence.

Final Thoughts

Bitcoin dominance in 2025 shares many similarities with the trends seen in 2021, leading many to speculate that an altcoin season is approaching. Historical patterns suggest that once Bitcoin dominance peaks and starts to decline, altcoins typically experience a surge.

While some analysts remain cautious, the growing interest in blockchain projects, Ethereum ETFs, and Layer-2 solutions points to the possibility of an altcoin rally. For investors, monitoring Bitcoin dominance, market sentiment, and regulatory developments will be crucial to making informed decisions.

As the crypto market evolves, diversifying your portfolio and staying informed will help you navigate the potential opportunities and risks in this dynamic space.
