Introduction
Between November 19-25, Bitcoin experienced a dramatic price plunge, losing nearly 35% of its value within a single week. The cryptocurrency dipped below the $4,000 threshold, continuing its downward trajectory after peaking at $20,000 in late 2017. This marks an 80% decline from its all-time high.

Key Factors Behind Bitcoin's Crash
1. Blockchain Project Bubble Burst
The market has been shaken by numerous low-quality blockchain projects exploiting the "public chain" narrative while engaging in speculative activities. Many fraudulent ICOs and token schemes eroded investor confidence when they collapsed.
2. BCH Hard Fork Conflict
The November 15 Bitcoin Cash (BCH) hard fork created significant market turbulence:
- Miners split between BCH ABC and BCH SV factions
- Community fragmentation weakened decentralization principles
- Investor fears about value dilution triggered sell-offs
3. Global Regulatory Crackdowns
Policy tightening across major economies intensified market panic:
| Country | Regulatory Action |
|---|---|
| United States | SEC penalties for ICO violations (November 16) |
| China | Complete ban on ICOs and crypto trading (2017) |
| Japan | Legalized ICOs under financial regulations (November 2018) |
| UK | Financial Conduct Authority warnings about crypto scams (September 2017) |
Blockchain Technology: Current Challenges
Performance Limitations
- Speed Constraints: Bitcoin processes ~6 transactions/sec vs Visa's 1,600
- Trilemma Paradox: Difficulty balancing decentralization, security, and scalability simultaneously
Successful Implementation Cases
- Distributed Databases
Example: People's Bank of China's blockchain-based asset securitization platform - Digital Bill Platforms
China's blockchain-powered commercial paper system improved settlement efficiency by 90%
Future Outlook for Cryptocurrencies
While the market correction has eliminated many speculative projects, legitimate blockchain applications demonstrate tangible value in:
- Financial infrastructure modernization
- Supply chain optimization
- Secure data sharing systems
The technology requires further technical breakthroughs and more实体经济-focused implementations to achieve sustainable growth.
