The debate over whether cryptocurrency can function as mainstream currency continues to grow louder as digital assets gain global attention. While some countries have experimented with adopting cryptocurrencies like Bitcoin as legal tender, central banks in many nations—including Malaysia’s central bank, Bank Negara—remain cautious. Despite the rising popularity of digital currencies, they are not recognized as official payment methods due to significant concerns around volatility, regulation, and financial stability.
This article explores the core reasons why cryptocurrency cannot currently serve as a widely accepted form of currency, the distinction between blockchain technology and crypto assets, and what central banks are doing instead to embrace digital innovation—such as developing central bank digital currencies (CBDCs).
The Volatility Problem: A Barrier to Everyday Use
One of the most critical issues preventing cryptocurrency from becoming a practical medium of exchange is its extreme price volatility.
Imagine buying a cup of coffee with Bitcoin today, only for that same amount of Bitcoin to double in value by tomorrow—or lose half its worth. This unpredictability makes it impractical for daily transactions. For any currency to function effectively, it must maintain relative price stability so consumers and merchants can trust its value over time.

Unlike traditional fiat currencies backed by governments and regulated monetary policies, cryptocurrencies like Bitcoin, Ethereum, and others derive their value purely from market demand and speculation. Their prices can swing dramatically within hours due to news events, regulatory announcements, or even social media influence.
Such instability undermines two key functions of money:
- Store of value: If an asset's price fluctuates wildly, people hesitate to save or hold it.
- Unit of account: Businesses need predictable pricing; volatile currencies make budgeting and accounting extremely difficult.
Without these foundational qualities, cryptocurrency remains more of a speculative investment than a functional currency.
Blockchain vs. Cryptocurrency: Understanding the Difference
A common misconception is that blockchain technology and cryptocurrency are the same thing. They’re not.
Blockchain is the underlying technological infrastructure—a decentralized, transparent, and tamper-resistant ledger system—that enables secure record-keeping across networks. It has vast applications beyond finance, including supply chain tracking, healthcare data management, and voting systems.
Cryptocurrencies, on the other hand, are digital assets built on top of blockchain networks primarily for transferring value or serving as investment vehicles.
Bank Negara emphasizes this distinction clearly: while it does not endorse cryptocurrencies as legal tender, it actively explores blockchain and distributed ledger technology (DLT) for improving financial efficiency and accessibility.
For instance, the central bank has been researching wholesale central bank digital currency (CBDC) since 2017—focusing on large-scale interbank settlements rather than retail use. These efforts aim to enhance cross-border payments and streamline domestic financial operations through tokenized deposits and secure DLT frameworks.
Central Bank Digital Currencies: The Regulated Alternative
Instead of embracing decentralized cryptocurrencies, many central banks are developing their own digital versions of national currencies—known as central bank digital currencies (CBDCs).
Unlike Bitcoin or Ethereum, CBDCs are:
- Issued and backed by a nation’s central bank
- Pegged to the value of the local fiat currency
- Fully integrated into the existing financial system
- Subject to regulatory oversight
This approach allows governments to harness the benefits of digitization—such as faster transactions, reduced fraud, and improved financial inclusion—without sacrificing control over monetary policy or financial stability.
Bank Negara confirms it is not planning to issue a retail CBDC in the near term but continues to evaluate its potential through pilot programs and international collaborations, including initiatives led by the Bank for International Settlements (BIS) Innovation Hub.
These projects focus on wholesale CBDC applications, where financial institutions use digital tokens for interbank settlements, potentially reducing settlement times from days to minutes.
Are Cryptocurrencies Legal? Regulatory Guidance You Need
In Malaysia, holding or investing in cryptocurrencies is not illegal—but there are important caveats.
Bank Negara advises the public to only trade digital assets through platforms approved by the Securities Commission (SC). These regulated exchanges operate under strict compliance standards designed to protect investors from fraud, market manipulation, and cyber threats.
Trading on unauthorized platforms carries high risks, including loss of funds and lack of legal recourse. By limiting activity to licensed venues, regulators aim to balance innovation with consumer protection.
It’s also crucial to understand that while you can legally own crypto assets, they are not legal tender. No merchant is obligated to accept them as payment, and their use in everyday commerce remains minimal compared to traditional payment methods like credit cards or mobile wallets.

Key Cryptocurrency Risks Beyond Volatility
While price swings are the most visible issue, several other factors limit cryptocurrency adoption as currency:
1. Scalability Challenges
Most public blockchains struggle with transaction speed and network congestion during peak usage. For example, Bitcoin processes about 7 transactions per second (TPS), whereas Visa handles over 24,000 TPS.
2. Energy Consumption
Proof-of-work cryptocurrencies like early versions of Bitcoin require massive computational power, raising environmental concerns.
3. Regulatory Uncertainty
Governments worldwide are still crafting rules for crypto taxation, anti-money laundering (AML), and consumer safeguards—creating uncertainty for users and businesses alike.
4. Security Vulnerabilities
While blockchain itself is secure, exchanges and wallets remain prime targets for hackers. Losses from crypto theft run into billions annually.
Frequently Asked Questions (FAQ)
Q: Can I use cryptocurrency to pay for goods and services in Malaysia?
A: Technically yes—if a merchant agrees—but it's extremely rare. Most businesses do not accept crypto due to volatility and regulatory ambiguity.
Q: Is blockchain technology safe for financial systems?
A: Yes, when properly implemented. Distributed ledger technology offers enhanced transparency, auditability, and resilience against fraud when used in controlled environments like CBDC trials.
Q: Will Malaysia ever adopt cryptocurrency as legal tender?
A: Unlikely in the foreseeable future. Bank Negara has consistently stated that due to volatility and lack of intrinsic value, private cryptocurrencies won’t replace the Malaysian ringgit.
Q: What’s the difference between CBDCs and stablecoins?
A: Both aim for price stability, but CBDCs are issued by central banks and represent direct liabilities of the state. Stablecoins are privately issued and usually backed by reserves like USD or bonds—though their reliability depends on transparency and regulation.
Q: Why are central banks exploring CBDCs if they don’t trust crypto?
A: Because CBDCs offer the efficiency of digital money without the risks of decentralization. They maintain central control over monetary supply while modernizing payment infrastructure.
Conclusion: Digital Evolution Without Disruption
Cryptocurrency may have ignited a revolution in how we think about money—but it is not yet ready to replace traditional currencies in everyday life. Its volatility, scalability issues, and regulatory challenges make it unsuitable as legal tender.
Instead, institutions like Bank Negara are choosing a measured path: rejecting unregulated crypto as currency while actively innovating through central bank digital currencies, tokenized deposits, and blockchain-based financial solutions.
The future of money isn’t about abandoning control—it’s about enhancing trust, efficiency, and access through responsible digital transformation.
As global financial systems evolve, one thing is clear: true innovation lies not in replacing fiat with crypto, but in integrating the best of both worlds—securely, sustainably, and inclusively.
