The world of digital finance is evolving at an unprecedented pace, and at the heart of this transformation lies cryptocurrency. A recent academic study conducted by the UK-based trading platform eToro in collaboration with Imperial College London suggests that digital assets are steadily progressing toward fulfilling the core functions of traditional money. According to the report titled Cryptocurrencies: Overcoming Barriers to Trust and Adoption, cryptocurrencies have already achieved one of the three fundamental characteristics of money—store of value—and could become a mainstream payment method within the next 10 years.
This milestone marks a pivotal moment in the evolution of financial systems, as decentralized digital currencies move beyond speculative assets and begin to demonstrate practical utility in everyday economic activity.
The Three Pillars of Money and Cryptocurrency’s Progress
For any asset to function as money, it must fulfill three essential roles:
- Store of value: The ability to retain purchasing power over time.
- Medium of exchange: Widely accepted for transactions.
- Unit of account: A standard measure for pricing goods and services.
The research highlights that cryptocurrencies like Bitcoin have already proven effective as a store of value. Despite market volatility, long-term holders view digital assets as a hedge against inflation and currency devaluation—similar to gold. However, widespread adoption as a medium of exchange and reliable unit of account still hinges on overcoming several critical challenges.

Five Key Challenges to Mainstream Adoption
For cryptocurrencies to achieve full monetary functionality, five major barriers must be addressed:
1. Scalability
Current blockchain networks often struggle to process high transaction volumes quickly and cost-effectively. To support global commerce, systems must scale to handle millions of transactions per second without congestion or soaring fees. Innovations like layer-2 solutions (e.g., Lightning Network) and next-generation blockchains are paving the way forward.
2. Usability
Ease of use remains a significant hurdle. Wallet setup, private key management, and transaction confirmation can confuse non-technical users. For mass adoption, cryptocurrency interfaces need to match the simplicity of mobile banking apps—intuitive, secure, and seamless.
3. Regulatory Clarity
Governments worldwide are taking varied approaches to crypto regulation. While some nations embrace innovation, others impose strict restrictions. Standardized global regulations would provide legal certainty for businesses and consumers, fostering trust and integration into traditional financial ecosystems.
4. Volatility Reduction
High price swings undermine confidence in crypto as a stable medium of exchange. While fiat currencies also fluctuate, crypto volatility is significantly higher. Stablecoins—digital currencies pegged to fiat assets—are emerging as a solution, offering blockchain efficiency with reduced price risk.
5. Privacy Enhancements
While blockchain offers transparency, many users demand stronger privacy protections. Public ledgers can expose transaction histories, raising concerns about surveillance and data misuse. Privacy-focused protocols and zero-knowledge proofs aim to balance transparency with confidentiality.
The Road to Everyday Use
Despite these hurdles, momentum is building. Iqbal Gandham, Managing Director at eToro, emphasizes that over eight years since the first Bitcoin transaction, we’re witnessing gradual but tangible progress toward daily usability. Cross-border payments represent one of the most compelling use cases: near-instant settlements, lower fees, and no intermediaries make crypto uniquely suited for international transfers.
Moreover, institutional interest continues to grow. Companies like Ledger, a French firm specializing in cryptocurrency hardware wallets, reported €25 million in profit last year. With a successful $75 million funding round in January and ongoing expansion plans, Ledger’s growth reflects rising consumer demand for secure digital asset management tools. Reports suggest major tech giants such as Siemens, Samsung, and Google are closely monitoring such companies’ financial performance—signaling deeper industry engagement.

The Bigger Picture: A Financial Revolution
As Professor William Knottenbelt and Dr. Zeynep Gurguc from Imperial College Business School note in their report, the cryptocurrency ecosystem is advancing rapidly—but not without complexity. The space is filled with technical jargon and fragmented systems, yet beneath the noise lies transformative potential.
Decentralized technologies could redefine not only how we pay for goods but also how we conceptualize ownership, identity, and financial inclusion. From enabling unbanked populations to access financial services to reshaping cross-border remittances, the implications extend far beyond price charts.
Even short-term trends reflect growing resilience. According to Coindesk data, Bitcoin rebounded nearly 13% from recent lows—from $5,853 to $6,597.89 in just days—demonstrating both market volatility and enduring investor confidence.

Frequently Asked Questions (FAQ)
Q: Can cryptocurrency really replace traditional money?
A: While full replacement is unlikely in the near term, crypto is increasingly complementing traditional finance—especially in areas like remittances, microtransactions, and digital ownership.
Q: Why is volatility a problem for using crypto as payment?
A: High price swings make it difficult for merchants to set consistent prices and for consumers to predict purchasing power. Stablecoins help mitigate this issue.
Q: How do regulations affect cryptocurrency adoption?
A: Clear regulations build trust and encourage institutional investment. Conversely, inconsistent or overly restrictive rules can stifle innovation and limit access.
Q: What does “store of value” mean in crypto context?
A: It means holding an asset that maintains or increases its worth over time. Bitcoin is often compared to digital gold due to its limited supply and growing acceptance.
Q: Are more companies starting to accept cryptocurrency payments?
A: Yes—major brands across e-commerce, travel, and tech sectors now accept crypto directly or through payment processors, signaling growing commercial viability.
Q: Is it safe to use cryptocurrency for everyday transactions?
A: With proper security practices—like using trusted wallets and enabling two-factor authentication—crypto transactions can be safe and efficient.
Final Thoughts
The journey toward mainstream cryptocurrency adoption is not a sprint but a marathon. While challenges remain in scalability, regulation, and user experience, the foundational pieces are being laid today. Backed by academic research, real-world use cases, and growing corporate interest, digital currencies are moving closer than ever to becoming a normal part of our financial lives.
As innovation accelerates and trust builds, the next decade may well witness a fundamental shift—not just in how we pay, but in how we think about money itself.
