Fiat money and cryptocurrencies each have unique security features and risks that should inform how you use and trust them.
Security Features of Fiat Money
The earliest forms of fiat money can be traced back to the Song Dynasty in China (around the 10th century) which began issuing paper money. The 20th century saw a significant shift towards fiat money systems.
Fiat money, such as dollars or euros, has been the backbone of modern economies since 1971 when US President Richard Nixon ended the direct convertibility of the U.S. dollar to gold.
This effectively transitioned the world to a predominantly fiat currency system. Fiat money’s security features are built on legal frameworks and centralized institutions that aim to protect both the currency and its users.
Government Backing
Fiat money is supported by the authority of the government that issues it, meaning that it is legally recognized as a valid form of payment.
Government backing not only gives confidence to the public but also ensures that strict laws are in place to protect against fraud and misuse.
For example, in the United States, the U.S. dollar is backed by federal law, and any act of counterfeiting is a serious crime with severe penalties.
The Role of Central Banks
Central banks, like the Federal Reserve in the United States or the European Central Bank in the Eurozone, manage their countries’ money supply and interest rates.
Central banks help to stabilize the economy by preventing excessive inflation or deflation.
An example of central bank control is when a central bank adjusts interest rates to either cool down or stimulate economic activity, thus ensuring the currency remains valuable and secure.
Governmental Deposit Insurance
Many countries offer deposit insurance to protect the funds of people who deposit money into banks.
In the United States, the Federal Deposit Insurance Corporation (FDIC) protects bank deposits up to a certain limit per depositor per insured bank. This insurance provides peace of mind to depositors, as their money is safe even if the bank fails.
For example, if a small community bank were to collapse, FDIC insurance would reimburse customers up to $250,000 per account, thereby reducing the risk of complete financial loss for individuals who have saved their money there.
Other Countries
In Canada, the Canada Deposit Insurance Corporation (CDIC) performs the same function as the FDIC does in the US up to CAD 100,000 per deposit insurance category.
In Germany, there is a statutory deposit protection scheme that adheres to a European Union directive, providing coverage up to €100,000. Additionally, German banks often participate in voluntary deposit insurance funds that offer significantly higher levels of protection.
It’s important to note that while the concept of deposit insurance is common, the specifics, such as coverage limits and the structure of the schemes, can vary significantly from country to country.
Regulation
A comprehensive network of regulations governs the use and management of fiat currencies. These regulations are designed to ensure transparency, accountability, and trust in the financial system.
For instance, the U.S. government mandates strict reporting requirements for financial institutions to prevent money laundering and terrorist financing.
This means banks must follow rigorous procedures to verify the identity of their customers, which in turn helps to secure the financial system from illegal activities.
Banknote Design
Governments continuously update the design and incorporate advanced security features, like holograms and watermarks, into their banknotes to stay ahead of counterfeiters.
An everyday example is how modern currency in many countries features intricate designs and special inks that change color when tilted, making it extremely difficult for counterfeiters to replicate.
Storage
The storage of fiat money has evolved significantly with technology, from physical safes and bank vaults to digital banking systems.
Banks and financial institutions invest heavily in security systems to protect deposits from theft or loss.
A typical example is a bank that uses multi-factor authentication and encrypted digital vaults to secure customers’ online accounts, ensuring that even if someone gains unauthorized access to a system, the actual funds remain protected.
Risks of Fiat Money
While fiat money is widely trusted, it is not without its vulnerabilities.
Central Bank Malfeasance or Manipulation
There is always a risk that those in control of the currency might misuse their power. Central bank malfeasance, such as the manipulation of interest rates or excessive money printing, can lead to economic instability.
A historical example is the hyperinflation experienced by Zimbabwe in the late 2000s, where excessive printing of money by the central bank led to astronomical inflation rates, severely devaluing the currency and wiping out people’s savings.
Robbery
Physical cash is inherently vulnerable to theft. Robbery of bank vaults or even individual bank branches can lead to significant financial losses.
For instance, the 1990s saw several high-profile bank robberies that significantly impacted law enforcement and security protocols.
One of the most notorious examples is the North Hollywood Shootout (1997), involving heavily armed and armored bank robbers who engaged in a prolonged and intense gun battle with the Los Angeles Police Department (LAPD).
This event spurred increased adoption of advanced security technologies and practices in banks, including:
- Improved CCTV surveillance systems
- Silent and enhanced alarm systems
- Increased use of dye packs that marked stolen cash and potentially the robbers themselves
- Changes in bank protocols like stricter cash handling procedures, enhanced staff training, and increased presence of armed guards
Counterfeiting
Counterfeiting is another critical risk for fiat money. Criminals may produce fake notes that can circulate in the economy if not detected by proper security features.
Political Instability
A country’s political instability can severely undermine the value of its fiat currency.
Changes in government, political unrest, or even the threat of war can cause rapid devaluation as investors lose confidence.
Global Economic Interconnectedness
In today’s interconnected global economy, the economic problems of one country can quickly spread to others.
This can lead to a domino effect, where the devaluation of one fiat currency can trigger a wider financial crisis.
Technological Vulnerabilities
As more and more fiat currency becomes digital, it becomes increasingly vulnerable to cyber attacks, and digital theft.
This shift creates opportunities for sophisticated criminals to exploit weaknesses in digital infrastructure, potentially leading to significant financial losses and systemic disruption.
Digital fiat can be stolen remotely through hacking, malware, and other cyberattacks – which extends beyond individual accounts to include entire financial institutions and even national payment systems.
The interconnected nature of digital finance means that a single successful attack can have cascading effects, impacting a wide range of individuals and businesses
A stark example of this vulnerability is the Bangladesh Bank heist of 2016.
Loss of Reserve Currency Status
The status of a global reserve currency confers significant economic advantages upon the issuing nation. Thus, a large portion of international trade, financial transactions, and central bank reserves are held in that currency.
However, this dominance is not guaranteed and can shift over time. If a nation’s fiat currency loses its reserve currency status, the economic repercussions can be profound.
Historically, the transition of reserve currency status has been a complex and often turbulent process. The decline of the British pound sterling and the rise of the US dollar in the 20th century serves as a prime example.
The transition involved significant economic and geopolitical shifts, highlighting the potential for instability and uncertainty during such periods.
In the modern context, with the rise of other economic powers and the emergence of alternative financial systems, the dominance of any single reserve currency is increasingly being questioned, introducing uncertainty and potential volatility into the global financial system.
Security Features of Cryptocurrencies
Cryptocurrencies operate on a fundamentally different model than fiat money, emphasizing digital security and decentralization.
Their security features are rooted in complex algorithms and distributed systems that provide transparency and resilience.
Decentralization
Unlike fiat money, which is controlled by a central banking authority, cryptocurrencies are typically decentralized, meaning that no single institution or government can control the entire network, reducing the risk of manipulation.
A classic example is Bitcoin, where thousands of nodes across the globe verify transactions, making it nearly impossible for any one party to alter the transaction history without consensus.
Cryptographic Design
At the heart of cryptocurrency security lies cryptography, a sophisticated branch of mathematics and computer science.
Cryptocurrencies leverage cryptographic techniques to secure transactions, control the creation of new units, and maintain the integrity of the digital ledger (blockchain), distinguishing it from traditional fiat currencies and digital payment systems.
Hashing
Cryptocurrencies utilize cryptographic hash functions, which take input data of any size and produce a fixed-size, seemingly random output (a hash).
These hash functions are one-way, meaning it’s computationally infeasible to derive the original input from the hash.
Hashing is crucial for creating secure transaction records and linking blocks in the blockchain. Any alteration to a transaction or block will result in a different hash, immediately revealing tampering.
Public-Key Cryptography (Asymmetric Cryptography)
Cryptocurrencies employ digital signatures, which use public-key cryptography to verify the authenticity and integrity of transactions.
- Each user possesses a pair of keys: a private key (kept secret) and a public key (shared with others).
- A user’s private key is used to create a digital signature for a transaction, which can be verified by anyone using the corresponding public key. This ensures that only the rightful owner can authorize transactions.
Thus, once a transaction is signed, the signer can not deny it.
Blockchain and Digital Ledgers
At the heart of most cryptocurrencies is blockchain technology—a digital ledger that records every transaction across a network of computers.
Ledgers are publicly available and immutable, meaning that once a transaction is recorded, it cannot be changed or deleted.
For example, if you buy a digital asset using Bitcoin, the transaction is recorded on the blockchain, where anyone can verify its authenticity and see that it has not been tampered with.
Transaction Transparency
Every transaction on a cryptocurrency network is visible on the blockchain, providing complete transparency. This helps in tracking funds and ensuring that all transactions are conducted according to the established rules of the network.
For instance, if a transaction seems suspicious, anyone with access to the blockchain can trace the origin and destination of the funds, thereby acting as a deterrent against illicit activities.
Anonymity
While transactions on many blockchains are transparent, the identities behind the transactions can remain anonymous. Users typically interact with cryptographic addresses rather than personal identities.
A good example is how individuals can donate to causes or pay for services using cryptocurrency without revealing their identity, similar to how one might use cash, but with the added benefit of digital traceability.
Irreversibility
One key security feature of cryptocurrencies is that transactions are irreversible. Once confirmed on the blockchain, a transaction cannot be undone, which reduces the risk of fraud through chargebacks.
For example, when you send Bitcoin to a merchant, the payment is final, and there is no way to reverse it, ensuring that both parties have certainty in the exchange.
Smart Contracts
Used in Decentralized Finance (DeFi) applications, smart contracts are self-executing contracts with the terms of the agreement directly written into code.
They automatically execute transactions when predetermined conditions are met, reducing the need for intermediaries and minimizing the risk of human error or manipulation.
For example, a smart contract could automatically release funds from an escrow account to a seller once a buyer confirms receipt of goods, ensuring that both parties are treated fairly without the need for a middleman.
Storage
Cryptocurrency storage differs significantly from traditional bank storage. Users can store their funds in digital wallets, which can be online (hot wallets) or offline (cold wallets).
Cold wallets, such as hardware devices or paper wallets, are not connected to the internet, making them less vulnerable to hacking.
Examples of hardware wallets include Ledger or Trezor, which keeps the private keys for your cryptocurrency offline, drastically reducing the risk of cyberattacks.
Regulation
The regulation of cryptocurrencies is an evolving area, as governments and regulatory bodies work to balance innovation with consumer protection.
Regulations in the cryptocurrency space often focus on anti-money laundering (AML), licensing, and market oversight by agencies such as the SEC, FinCEN, and CFTC.
A real-world example is how exchanges like Coinbase comply with various licensing requirements and regulatory frameworks to ensure that they operate safely and transparently for their users.
Securities and Exchange Commission (SEC)
The SEC is the U.S. government agency responsible for protecting investors, maintaining fair, orderly, and efficient markets, and facilitating capital formation.
The SEC’s oversight aims to protect investors from fraudulent schemes and ensure transparency in the market.
For example, the SEC investigates and takes action against initial coin offerings (ICOs) that are found to be unregistered securities offerings, ensuring that investors are provided with the necessary information to make informed decisions.
Financial Crimes Enforcement Network (FinCEN)
FinCEN is a bureau of the U.S. Department of the Treasury that collects and analyzes financial transactions to combat domestic and international money laundering, terrorist financing, and other financial crimes.
FinCEN’s role in the cryptocurrency space centers on enforcing anti-money laundering (AML) and combating the financing of terrorism (CFT) regulations.
Virtual currency exchanges and administrators are considered money service businesses (MSBs) and are required to register with FinCEN.
This oversight is crucial for preventing the use of cryptocurrencies in illicit activities and maintaining the integrity of the financial system. For example, FinCEN imposes fines on exchanges that fail to implement adequate AML/CFT measures.
Commodity Futures Trading Commission (CFTC)
The CFTC is the U.S. agency that regulates the U.S. derivatives markets, which include futures, options, and swaps.
In the cryptocurrency context, the CFTC has jurisdiction over cryptocurrency derivatives, such as Bitcoin futures.
The CFTC’s oversight ensures that these markets are fair, efficient, and transparent, and that they are not susceptible to manipulation.
State Regulations
Cryptocurrency regulations in the U.S. can differ significantly between federal and state levels. While federal agencies set overarching guidelines, individual states might impose additional regulations that reflect local priorities.
For example, New York’s BitLicense regulations require cryptocurrency businesses to meet higher standards of transparency and security, which may differ from requirements in other states, ensuring a layered approach to consumer protection.
Risks of Cryptocurrency
Despite the advanced security features of cryptocurrencies, several risks can affect users and the broader market.
Fraudulent Digital Assets and Platforms
The cryptocurrency market is susceptible to fraudulent schemes, including the creation of deceptive digital assets and platforms. Investors may be misled by false promises of high returns, only to discover that the underlying project lacks legitimacy.
Mechanism:
- Perpetrators develop counterfeit digital assets or platforms, often accompanied by sophisticated marketing campaigns.
- These schemes capitalize on investor enthusiasm and a lack of due diligence.
- Upon securing substantial investments, the developers may abandon the project, resulting in significant financial losses for investors.
Impact:
- Investors suffer financial losses due to the inherent lack of transparency and accountability in such fraudulent ventures.
- This undermines confidence in the broader cryptocurrency market.
Example: The BitConnect Ponzi scheme. BitConnect was a cryptocurrency lending platform that promised extraordinarily high returns. It heavily relied on referral programs and created its own token, BCC. Eventually, it was revealed to be a Ponzi scheme, and the platform collapsed, causing massive financial losses for investors.
Cybersecurity Vulnerabilities and Digital Asset Theft
The digital nature of cryptocurrencies renders them vulnerable to cyberattacks, posing a significant risk to investors. Malicious actors may exploit security vulnerabilities in digital exchanges and wallets to illicitly acquire digital assets.
Mechanism:
- Cybercriminals employ sophisticated hacking techniques to infiltrate cryptocurrency exchanges and digital wallets.
- These attacks can result in the unauthorized transfer of substantial digital asset holdings.
Impact:
- Investors experience direct financial losses due to the theft of their digital assets.
- These attacks highlight the critical importance of robust cybersecurity measures within the cryptocurrency ecosystem.
Example: The Mt. Gox hack is a prime example. In 2014, the Tokyo-based Bitcoin exchange Mt. Gox, which was handling a large percentage of Bitcoin transactions at the time, suffered a massive hack. Hundreds of thousands of Bitcoins were stolen, leading to the exchange’s collapse.
Market Manipulation and Volatility
The cryptocurrency market’s inherent volatility and decentralized structure create opportunities for manipulative practices, such as coordinated price manipulation schemes. These can lead to substantial financial losses for unsuspecting investors.
Mechanism:
- Groups of traders or public figures may engage in coordinated efforts to artificially inflate the price of a digital asset through manipulative trading practices.
- Once the price reaches a predetermined peak, these traders liquidate their holdings, causing a rapid price decline.
Impact:
- Investors who enter the market during the artificial price inflation phase experience significant financial losses.
- These manipulations contribute to market instability and erode investor confidence.
Example: “Pump-and-dump” schemes like the one involving the sale of Airborne Wireless Network securities are a real risk in the cryptocurrency market. Social media sites are commonly used to coordinate these schemes. Many smaller less known coins are often the target of these schemes.
Regulatory Ambiguity and Jurisdictional Challenges
The nascent nature of the cryptocurrency market presents regulatory challenges, characterized by ambiguity and jurisdictional complexities.
The lack of uniform regulatory frameworks across jurisdictions creates an environment of uncertainty.
Mechanism:
- Varied regulatory approaches across different jurisdictions like Federal vs State laws create a fragmented regulatory landscape.
- The absence of clear regulatory guidelines can impede market development and increase the risk of illicit activities.
Impact:
- Regulatory uncertainty can deter institutional investment and hinder the development of a mature cryptocurrency market.
- The lack of clear regulatory frameworks can facilitate fraudulent activities and impede law enforcement efforts.
Example: The ongoing debate and differing rulings on whether certain cryptocurrencies are securities or commodities in the U.S. The SEC and CFTC have taken different stances on various digital assets, leading to legal battles and regulatory uncertainty. The Ripple (XRP) case is a good example. The SEC filed a lawsuit against Ripple, alleging that XRP is a security.
