This study examines the determinants of price movements for five major cryptocurrencies—Bitcoin, Ethereum, Dash, Litecoin, and Monero—using weekly data from 2010–2018. Key findings highlight the interplay between cryptomarket dynamics, macroeconomic factors, and investor behavior.
Key Findings
Cryptomarket Factors
Market Beta & Trading Volume
- Short- and long-run price movements for all five cryptocurrencies are significantly influenced by cryptomarket-specific variables, including market beta, trading volume, and volatility.
- Bitcoin and Ethereum exhibit higher sensitivity to market fluctuations, with long-run multipliers of 0.79 and 0.38, respectively.
Volatility
- A 1% increase in market volatility reduces Bitcoin and Ethereum prices by 0.15 units long-term, with similar effects observed for Dash, Litecoin, and Monero.
Attractiveness & External Factors
- Google Search Trends: Investor interest (proxied by search frequency) has a delayed but significant long-term impact on prices, particularly for Bitcoin (+1.27 units per 1% increase in attractiveness).
- SP500 Index: Weak positive long-term correlation with Bitcoin, Ethereum, and Litecoin, though short-term effects are negative for Bitcoin (−0.20 units).
Error Correction Models
Cointegrated series converge to equilibrium at varying speeds:
- Bitcoin: 23.68% monthly adjustment
- Ethereum: 12.76%
- Dash: 10.20%
- Litecoin: 22.91%
- Monero: 14.27%
Methodology
- ARDL Technique: Accounts for mixed integration orders (I(0) and I(1)) among variables.
- Crypto 50 Index: Tracks top 50 cryptocurrencies by market cap (92% of total market) to model aggregate trends.
Implications
- Investors: Short-term strategies should prioritize volatility management, while long-term positions benefit from tracking investor sentiment and macroeconomic linkages.
- Regulators: Cryptocurrencies’ decoupling from traditional assets underscores the need for tailored risk frameworks.

FAQs
Q1: Why does Bitcoin show higher sensitivity to market beta?
A: Bitcoin’s dominance in market cap (~34% during the study) amplifies its responsiveness to aggregate cryptomarket movements.
Q2: How reliable are Google search trends as an attractiveness metric?
A: High correlation (p < 0.01) with price shifts confirms its utility, though lag effects suggest gradual market recognition.
Q3: What limits the SP500’s influence on crypto prices?
A: Cryptocurrencies’ decentralized nature weakens traditional equity market linkages, though spillovers occur during crises.

Conclusion
The study underscores the dual role of internal (e.g., trading volume) and external (e.g., SP500) factors in shaping cryptocurrency prices, with ARDL models providing robust tools for forecasting amid high volatility. Future research could explore altcoin-specific bubbles and regulatory impacts.
