The Rise and Challenges of Cryptocurrency: A Global Perspective

·

The rapid evolution of digital finance has placed cryptocurrency at the center of global economic discourse. In a keynote address titled "The Rise and Challenges of Cryptocurrency," Nankai University President Chen Yulu offered a comprehensive analysis of the transformative forces shaping the future of money, regulation, and financial sovereignty. Delivered during the 2025 China Digital Economy Development and Governance Academic Conference, his insights shed light on the technological foundations, geopolitical implications, and strategic positioning of nations in the emerging digital asset landscape.

Understanding Cryptocurrency: Types and Core Characteristics

At its foundation, cryptocurrency is a digital currency operating through decentralized computer networks. Ownership is recorded on a distributed ledger—most commonly, blockchain—secured by consensus mechanisms like Proof of Work (PoW). This technology enables trustless transactions without centralized intermediaries.

There are three primary categories of cryptocurrencies:

Cryptocurrencies exhibit seven defining features:

  1. Decentralization – Distributed across nodes globally
  2. Security – Protected by cryptographic protocols
  3. Scarcity – Many have capped supply (e.g., Bitcoin’s 21 million cap)
  4. Pseudonymity – Transactions are traceable but not directly tied to identities
  5. High price volatility – Rapid value fluctuations due to speculative demand
  6. Energy consumption – Significant power use in PoW mining
  7. Global accessibility – Enables near-instant cross-border transfers without currency conversion

The Growing Influence of Cryptocurrency in Global Finance

Since the mining of Bitcoin’s Genesis Block in January 2009, what began as an experimental digital currency has evolved into a significant component of the global financial ecosystem. Over 130 countries now engage in discussions about integrating crypto into mainstream finance.

A pivotal moment occurred in January 2024 with the approval of spot Bitcoin ETFs in the United States—a landmark step toward institutional adoption. By December 2024, Bitcoin surpassed $100,000 per coin, propelling the total crypto market capitalization from $800 billion to $3.4 trillion within just two years. Notably, crypto’s share of G6 central banks’ liquidity surged from less than 1% in 2009 to 12% by the end of 2024.

This shift reflects a broader trend: Bitcoin is transitioning from a niche speculative asset to a recognized mainstream investment class. The proposed Strategic Bitcoin Reserve (SBR) under the new U.S. administration further accelerates this transformation, signaling national-level recognition of digital assets.

The U.S. Strategy: Building a Tripartite Digital Dollar Dominance

Recent policy shifts indicate that the United States is constructing a "three-pronged" strategy to extend its financial hegemony into the digital era. This framework rests on three pillars:

  1. Strategic Bitcoin Reserves (SBR)
  2. Dollar-pegged stablecoins
  3. U.S.-controlled digital financial infrastructure

Five Key Shifts in U.S. Crypto Policy

  1. Regulatory Evolution: Regulatory bodies have moved from suppression to guided oversight. The appointment of Paul Atkins, a known crypto advocate, as SEC chair marks a clear pivot toward innovation-friendly regulation.

  2. Legislative Support: Two major bills—FIT21 and GENIUS—are advancing through Congress:

    • FIT21 establishes a regulatory framework for digital assets, clarifying jurisdiction between SEC and CFTC.
    • GENIUS creates oversight for stablecoins like USDT and USDC, which dominate 90% of the market.
  3. Asset Stratification: The U.S. plans to acquire up to one million Bitcoins for strategic reserves while banning domestic CBDC development—a move designed to eliminate competition for dollar dominance.
  4. Corporate Adoption: Major firms including Apple, Tesla, and MicroStrategy are incorporating crypto into corporate treasuries. BlackRock’s IBIT ETF alone holds 45% of all Bitcoin in ETFs, with total assets exceeding $153 billion by early 2025.
  5. Tax Incentives: The IRS introduced flexible accounting methods for crypto gains in 2025, easing short-term tax burdens and encouraging compliance within regulated platforms.

Europe's Approach: Regulation, Sustainability, and Market Unity

In contrast to U.S. strategic accumulation, the European Union emphasizes regulatory coherence and environmental responsibility. The Markets in Crypto-Assets (MiCA) framework took full effect on December 31, 2024, establishing a unified regulatory environment across member states.

MiCA classifies crypto assets into three categories with tailored oversight and imposes strict rules on stablecoin issuers and exchange operators. Beyond consumer protection and financial stability, MiCA promotes green finance by taxing energy-intensive PoW blockchains and incentivizing migration to low-carbon alternatives like Proof-of-Stake (PoS).

This regulatory clarity strengthens Europe’s position in global standard-setting while reshaping mining geography away from high-emission regions.

Global Competition: Stablecoins vs. Sovereign Digital Currencies

Over 130 economies are exploring Central Bank Digital Currencies (CBDCs), with China’s digital yuan leading in scale and deployment. Meanwhile, G20 nations like Japan, South Korea, India, and Russia are accelerating their own digital currency initiatives.

Despite this momentum, dollar-backed stablecoins maintain a significant lead:

However, growing fragmentation risks loom:

Stablecoins: Bridging Traditional and Digital Finance

Stablecoins are emerging as the critical link between legacy finance and blockchain innovation.

They’ve outpaced U.S. M2 growth during periods of fiscal uncertainty, reinforcing demand for dollar-denominated assets. In the first 11 months of 2024 alone, stablecoins facilitated $27.1 trillion in transactions—many involving peer-to-peer and cross-border business payments.

Moreover, platforms like Visa and Stripe are integrating stablecoin rails, signaling mainstream acceptance of blockchain-based settlement systems.

Geopolitical Risks: U.S. Crypto Hegemony and Financial Security

America’s aggressive crypto strategy poses several challenges to China’s financial sovereignty:

  1. Capital Outflows & Currency Pressure: Rising Bitcoin valuations and widespread stablecoin usage strengthen dollar dominance, potentially undermining RMB internationalization.
  2. DeFi Regulatory Arbitrage: Favorable U.S. policies attract global DeFi talent and capital, building long-term technological advantages.
  3. Standards Competition: U.S. leadership in core protocols and EU regulatory influence via MiCA threaten China’s ability to shape global norms.
  4. Digital Sanctions Precedent: The seizure of Russian crypto assets during the Ukraine conflict demonstrates the power—and danger—of centralized control over decentralized systems.

While current crypto valuations may reflect speculative excesses vulnerable to correction, the underlying infrastructure race is real. As President Chen emphasized, maintaining strategic clarity and prioritizing financial services for the real economy remains essential.
