The total market capitalization of cryptocurrencies, including the most famous Bitcoin, declined to one-fifth of its peak value in 2018. Investors grew disillusioned with the decentralized nature of digital currencies. Amid this shift, several nations began exploring Bitcoin-based solutions to transform their national currencies into digital assets, unlocking unprecedented tools for financial system oversight.
The Rise and Fall of Cryptocurrency Markets
Initially conceived as a niche interest among cryptographers, Bitcoin's value surged exponentially by 2017—reaching $20,000 per coin—before crashing in 2018. Key factors behind this volatility:
- Speculative Frenzy: Prices became detached from utility, driven by investor sentiment.
- Regulatory Crackdowns: China’s bans on exchanges and ICOs disrupted 70% of global mining operations.
- Technical Vulnerabilities: Exchange hacks, wallet thefts, and consensus splits (e.g., Bitcoin Cash) eroded trust.

"Digital currency lets us monitor transactions in real time, cutting fraud and tax evasion," notes Dr. Zhang Ning of the Chinese Academy of Social Sciences.
