The cryptocurrency market has long been characterized by high volatility and interdependence among digital assets. One of the most critical dynamics shaping investor strategy is the strong correlation between cryptocurrencies—particularly how alternative coins (altcoins) move in tandem with Bitcoin (BTC), the market leader. Understanding this relationship is essential for effective portfolio management, risk mitigation, and long-term investment planning.
Market Correction Amplifies Cryptocurrency Correlation
Historically, most cryptocurrencies have mirrored Bitcoin’s price movements, especially during periods of market stress. This phenomenon is known as cryptocurrency correlation, where the price action of altcoins closely follows that of BTC. Legacy cryptocurrencies like Ethereum (ETH) and Litecoin (LTC) have shown particularly strong alignment with Bitcoin due to their established market presence and investor perception as foundational digital assets.
Recent market data reveals the extent of this correlation:
- ETH / BTC: 0.68
- LTC / BTC: 0.73
- UNI / BTC: 0.32
- AAVE / BTC: 0.31
- DOT / BTC: 0.54
These figures represent the average correlation coefficients observed in 2021, with values closer to 1 indicating a stronger relationship. As seen above, traditional altcoins such as ETH and LTC exhibit high correlation, meaning they tend to rise and fall alongside Bitcoin.

Diversification in Crypto: Is It Still Effective?
A common question among investors is whether diversification—a cornerstone of traditional finance—applies effectively in the crypto space. The answer depends heavily on asset selection.
During bull markets, newer decentralized finance (DeFi) tokens like Uniswap (UNI) and Aave (AAVE) often display lower correlation with Bitcoin, sometimes as low as 0.31–0.32. This reduced linkage suggests potential for portfolio diversification, allowing investors to capture unique growth drivers within the DeFi ecosystem.
However, during bear markets or sharp corrections, correlations tend to converge toward 1. For example, UNI and AAVE saw their correlation with BTC jump from around 0.25 in early spring 2021 to nearly 0.75 after the broader market downturn. This “risk-on, risk-off” behavior illustrates that in times of panic, investors treat most cryptocurrencies as a single asset class, selling off everything indiscriminately.
In essence: DeFi tokens offer diversification benefits in bullish cycles, but these advantages diminish during market-wide sell-offs.
This cyclical nature underscores the importance of timing and macro awareness when constructing a crypto portfolio.
Ethereum Gas Fees Drop to 2021 Lows Ahead of EIP-1559
Amid the broader market correction, Ethereum’s network activity has cooled significantly, leading to a dramatic decline in gas fees—the cost of executing transactions on the blockchain. In February 2021, average gas prices spiked to 243.33 gwei, driven by surging DeFi and NFT activity. By mid-year, however, fees had plummeted to just 16.63 gwei, marking the lowest level of the year.
Several factors contributed to this decline:
- Reduced on-chain activity due to market uncertainty
- Increased adoption of Layer 2 scaling solutions like Polygon, which offload transactions from Ethereum’s mainnet
- Investor caution following the price drop
Despite lower usage, Ethereum remains at the forefront of innovation. The highly anticipated EIP-1559 upgrade aims to overhaul the fee structure by introducing a base fee that is burned rather than paid to miners. This deflationary mechanism could increase ETH’s scarcity over time, potentially boosting its long-term value proposition.

Strong Year-over-Year Performance Despite Volatility
While short-term fluctuations have caused concern among retail investors, the year-over-year (YoY) performance of major digital assets remains exceptionally strong:
- Bitcoin (BTC): +333.01%
- Ethereum (ETH): +1010.14%
Just one year ago, Bitcoin traded below €8,000; today, it holds above the €30,000 mark. Similarly, Ethereum surged from approximately €200 in June 2020 to over €2,000 in 2021. These gains highlight the transformative potential of digital assets, even amidst pronounced volatility.
Such performance reflects growing institutional adoption, increased regulatory clarity in certain regions, and expanding use cases across decentralized applications.
Bitcoin as a Hedge Against Inflation
With global inflation concerns rising, Bitcoin has re-emerged as a compelling hedge against monetary devaluation.
In May 2021, the U.S. Consumer Price Index (CPI) reached 5%, the highest level since the aftermath of the 2008 financial crisis. Analysts point to expansive monetary policies by central banks—especially the Federal Reserve—as a primary driver. Nordea economist Andreas Steno Larsen noted that more than 20% of all U.S. dollars in circulation were created in 2020 alone, fueling fears of sustained inflation.
Bitcoin’s design directly counters this trend:
- Fixed supply cap of 21 million coins
- Approximately 18.74 million already mined, with dwindling new issuance
- Thousands of BTC likely lost forever due to forgotten private keys
This built-in scarcity mirrors precious metals like gold, positioning Bitcoin as "digital gold." Unlike fiat currencies, which can be printed indefinitely, Bitcoin’s supply is algorithmically constrained—making it inherently resistant to inflation.
As macroeconomic uncertainty persists, many investors view BTC not just as a speculative asset, but as a long-term store of value.
Frequently Asked Questions (FAQ)
Q: Why are most altcoins highly correlated with Bitcoin?
A: Bitcoin dominates market sentiment and liquidity flow. When BTC moves sharply, it triggers broad risk-on or risk-off behavior across the crypto market, pulling altcoins along due to shared investor psychology and trading platforms.
Q: Can I diversify within the cryptocurrency market?
A: Yes, but selectively. DeFi tokens and niche projects often show lower correlation during bull runs. However, during market crashes, correlations spike—limiting diversification benefits.
Q: How does EIP-1559 affect Ethereum’s value?
A: By burning transaction fees instead of giving them to miners, EIP-1559 introduces deflationary pressure. If network usage remains high, ETH could become scarcer over time, potentially increasing its value.
Q: Are lower gas fees good or bad for Ethereum?
A: Lower fees improve user experience and accessibility but may indicate reduced demand. They’re beneficial short-term for users but could reflect declining network activity.
Q: Is Bitcoin truly an inflation hedge?
A: While not proven over decades like gold, Bitcoin’s fixed supply makes it theoretically resistant to inflation. Growing institutional adoption supports its role as a macro hedge, though price volatility remains a factor.
Q: What causes crypto correlations to increase during downturns?
A: During market stress, investors de-risk by selling all crypto assets indiscriminately. This “flight to cash” behavior erases temporary decoupling and forces correlations toward 1.
