When building an investment portfolio, understanding how different assets interact is crucial. For digital asset investors, the relationship between Bitcoin (BTC) and Bitcoin Cash (BCH) is particularly significant. This article explores their correlation, diversification potential, and strategies for managing risk when holding both cryptocurrencies.
The Basics of Correlation in Investing
Correlation measures how two securities move in relation to each other. It is expressed as a coefficient ranging from -1 to +1.
A perfect positive correlation (+1) means they always move in the same direction. A perfect negative correlation (-1) means they always move in opposite directions. A correlation of zero indicates no relationship.
For portfolio diversification, investors often seek assets with low or negative correlation. Combining such assets can help reduce overall portfolio risk.
Analyzing the BTC and BCH Relationship
Historical Correlation Data
Over a three-month period, Bitcoin and Bitcoin Cash have shown a strong positive correlation of 0.88. This high correlation indicates they tend to move together in the same direction most of the time.
The overlapping price movement suggests that much of the risk affecting one cryptocurrency also affects the other. This limits the diversification benefits of holding both in the same portfolio.
Why Are They So Highly Correlated?
Bitcoin Cash originated from a hard fork of Bitcoin. They share much of their history, underlying technology, and market perception.
Both are influenced by similar market factors:
- Broader cryptocurrency market sentiment
- Regulatory developments
- Technological advancements in blockchain
- Institutional adoption news
- Macroeconomic factors affecting digital assets
Risk and Return Comparison
Volatility and Risk Profiles
Despite their correlation, Bitcoin and Bitcoin Cash have different risk-return characteristics. Bitcoin is generally less volatile than Bitcoin Cash, with about 2.15 times less risk based on historical volatility patterns.
However, Bitcoin Cash has shown higher potential returns over certain periods. In a recent 90-day scenario, Bitcoin Cash generated approximately 0.35 returns per unit of risk, compared to Bitcoin's 0.19.
Performance Considerations
While both cryptocurrencies have demonstrated "good" risk-adjusted performance compared to global equities, they rank lower than 81% of all investments in this regard. This highlights the inherently speculative nature of cryptocurrency investments.
Diversification Potential
Limited Diversification Benefits
With a correlation of 0.88, Bitcoin and Bitcoin Cash offer very poor diversification when combined in a portfolio. The high positive correlation means that holding both doesn't significantly reduce overall risk exposure.
During market downturns affecting cryptocurrencies, both assets would likely decline together, providing little protection through diversification.
When Diversification Might Work
Despite the high correlation, there might be brief periods where their prices diverge due to:
- Different development updates
- Varying community support
- Separate partnership announcements
- Chain-specific technical issues
These temporary divergences might create short-term trading opportunities but don't significantly change the long-term correlation picture.
Pair Trading Strategy
How Pair Trading Works
Pair trading involves taking opposite positions in two highly correlated assets. For Bitcoin and Bitcoin Cash, this might mean going long on one while shorting the other.
The goal is to profit from temporary price divergences while maintaining a market-neutral position. This strategy hedges against overall market movements, focusing instead on the relative performance of the two assets.
Benefits of BTC/BCH Pair Trading
This approach can help manage unsystematic risk specific to these cryptocurrencies. If one position performs unexpectedly, the other may offset some losses.
Pair trading also reduces exposure to broader market movements. If the entire cryptocurrency sector declines due to negative news, the short position might balance losses from the long position.

Risk Management Considerations
Understanding the Limitations
While pair trading can reduce some risks, it doesn't eliminate all potential losses. The high correlation between Bitcoin and Bitcoin Cash means price divergences may be small and short-lived.
Transaction costs, timing challenges, and the need for constant monitoring make this strategy more suitable for experienced traders.
Portfolio Integration
For most investors, simply holding both cryptocurrencies provides limited diversification benefits. Consider complementing crypto holdings with assets that have lower correlation, such as:
- Traditional equities
- Bonds
- Commodities
- Real estate investment trusts (REITs)
Future Outlook and Considerations
Changing Correlation Patterns
While historical data shows high correlation, this relationship might evolve. Factors that could decrease correlation include:
- Different technological development paths
- Varying adoption rates for specific use cases
- Separate regulatory treatment
- Changing investor perceptions
Monitoring Correlation Over Time
Regularly review the correlation between assets in your portfolio. Correlation coefficients can change over different time horizons and market conditions.
Use updated correlation data when making investment decisions rather than relying solely on historical patterns.
Frequently Asked Questions
How often should I check the correlation between Bitcoin and Bitcoin Cash?
Review correlation data at least quarterly, or whenever significant market events occur. Correlation can change over time, so regular monitoring helps maintain optimal portfolio allocation. Major regulatory announcements or technical upgrades might particularly affect their relationship.
Can I achieve better diversification with other cryptocurrency pairs?
Yes, pairing cryptocurrencies with different use cases or market caps might offer better diversification. Consider combining established coins like Bitcoin with assets from different sectors such as decentralized finance tokens or privacy-focused cryptocurrencies that may have lower correlation.
What tools can I use to monitor cryptocurrency correlations?
Several platforms provide correlation tracking for digital assets. These tools typically offer visual representations of relationship strength over various time periods. Look for platforms that update frequently and allow custom time frame analysis for the most accurate assessment.
How does correlation affect long-term holding strategies?
For buy-and-hold investors, high correlation between assets reduces diversification benefits. If holding both Bitcoin and Bitcoin Cash long-term, recognize that your portfolio may experience amplified gains or losses during market movements rather than smoothed returns.
Should correlation be the only factor when building a crypto portfolio?
No, correlation is just one consideration. Also evaluate fundamental factors like technology, adoption, team, use case, and regulatory environment. A well-rounded approach combines correlation analysis with fundamental and technical analysis for better decision-making.
What's the difference between correlation and causation in crypto markets?
Correlation shows that two assets move together, but doesn't explain why. Causation would mean one asset's movement directly affects the other. With Bitcoin and Bitcoin Cash, their correlation likely comes from shared market factors rather than direct causation.
Conclusion
Bitcoin and Bitcoin Cash maintain a strong positive correlation that limits their diversification potential when held together. While pair trading strategies might offer some risk management benefits, most investors will find better diversification by including assets with lower correlation to cryptocurrencies.
Understanding these relationships helps build more resilient portfolios that can better withstand market volatility. Regular monitoring of correlation patterns remains essential as the cryptocurrency landscape continues to evolve.
