Introduction
This study aims to identify speculative bubbles in cryptocurrency markets by analyzing bubble formation periods and the historical events influencing price fluctuations. The findings aim to equip investors with actionable insights for informed decision-making.
Methodology
We employ the Generalized Supremum Augmented Dickey-Fuller (GSADF) test (Phillips et al., 2015a) to detect bubbles across:
- The entire cryptocurrency market
Three major cryptocurrencies:
- Bitcoin (BTC)
- Ethereum (ETH)
- Ripple (XRP)
Key Findings
Bubble Formation Dynamics
Positive Speculative Bubbles: Occur when:
- Market transactions expand continuously.
- Prices deviate from intrinsic value due to predictable information.
- Result: Upward price trends during bubble formation.
Negative Speculative Bubbles: Emerge when:
- Market transactions expand continuously.
- Prices deviate from intrinsic value due to unpredictable information.
- Result: Downward price trends.
Bitcoin’s Dominance
Speculative bubbles in the overall cryptocurrency index and Bitcoin prices often synchronize due to BTC’s 68% market dominance. Shock events in Bitcoin frequently ripple through the broader market.

FAQs
1. What triggers speculative bubbles in cryptocurrencies?
Bubbles form when prices detach from fundamental values, driven by herd behavior, media hype, or regulatory announcements.
2. How does Bitcoin’s market share affect bubble detection?
Bitcoin’s dominance means its price movements heavily influence the broader market, making it a benchmark for bubble analysis.
3. Can the GSADF test predict future bubbles?
While GSADF identifies historical bubbles, it doesn’t forecast future ones. Investors should combine it with fundamental analysis.
4. Are altcoins like ETH and XRP less prone to bubbles?
Smaller market caps may amplify volatility, but bubble patterns depend on liquidity and adoption rates.
