What Is Digital Currency? Types, Risks, and How to Protect Yourself
Payment methods have seen an impressive evolution over the years. We have moved from coins to cash to cards, and now to crypto and central bank digital currencies. Juniper Research projects that the value of global digital currency transactions will reach $213 billion by 2030, up from $100 million in 2023.1
Explore key elements of digital currencies, including important distinctions between different payment methods, benefits and challenges of various methods, the most persistent fraud threats these methods face, and the strategies needed to keep them safe.
Key Takeaways
- Digital currencies are a kind of financial asset. They work like regular money but only exist online.
- Juniper Research projects that the value of global digital currency transactions will reach $213 billion by 2030.1
- Digital currencies can either be publicly issued (e.g., central bank digital currencies) or privately issued (e.g., cryptocurrencies).
- Digital currencies are vulnerable to numerous fraud tactics, including phishing attacks, social engineering scams, account takeover, and even physical threats.
What is Digital Currency?
Digital currency, sometimes known as digital money, electronic money, or electronic currency, is a financial asset that only exists digitally. Unlike traditional cash, such as banknotes or coins, you cannot touch, store, or change them. You can only exchange them in an electronic environment.
Digital currencies can be privately or publicly issued. Privately-issued digital currencies are digital money created and managed by private companies, not a central government. Publicly issued digital currencies, known as central bank digital currencies (CBDCs), are digital versions of national currencies, issued and backed by a central authority.
Types of Digital Currency
Digital currencies fall into four unique categories, based on their specific characteristics. The key types of digital currencies include:
Central Bank Digital Currencies
According to recent data from the Atlantic Council, 49 countries have launched CBDC pilot programs. Three countries (the Bahamas, Jamaica, and Nigeria) have launched their own national digital currency.2 Meanwhile, the eurozone is planning its own digital currency between 2027 and 2029.3
Cryptocurrencies
Cryptocurrency (often called crypto) is a form of digital money. It is decentralized and secured by cryptography, which is used to protect its transactions. Cryptocurrencies operate on digital ledger technology such as blockchain.
Unlike CBDCs, a central authority does not control or monitor cryptocurrencies. Notable names in the cryptocurrency space include Bitcoin and Ethereum.
Stablecoins
Stablecoins are cryptocurrencies that have their value tied to stable assets like fiat currencies or commodities such as gold. This gives them greater stability than cryptocurrencies, making them more suitable for everyday transactions. Notable stablecoin names include Tether and USD Coin.
Virtual Currencies
Virtual currencies are currencies that are often used in specific platforms like gaming ecosystems. Its developers, network, or the organization that created it frequently control it.

Digital Currency in the Real World: Pros & Cons
There are both benefits and drawbacks when using digital currencies. Here are some key points to consider:
Digital Currency Benefits
- Stronger Central Bank Authority. Central banks often emerge as the big winners with digital currencies. CBDCs allow national central banks to strengthen their positions in digital finance by providing citizens with a secure, state-backed payment option.
- Strategic Autonomy Resilience. Using CBDCs, nations can reduce their reliance on foreign or private payment systems, strengthening their economic independence.
- Expanding Financial Inclusion: Digital currencies open new financial opportunities to unbanked or underbanked populations, who number 1.4 billion worldwide, according to figures from the World Bank.4 Many unbanked people do not have bank accounts. However, they can use mobile devices to pay merchants, vendors, or utility providers.
- Enhanced Privacy: Unlike other peer-to-peer methods, digital currencies let users transfer money without an internet connection. This makes digital transactions feel like cash swaps.
- Cross-Border Efficiency: The digital euro is expected to enhance cross-border payments by making them more seamless and efficient.
Digital Currency Risks
- Privacy Concerns: While digital currencies can be exchanged without a digital connection, they are centralized and issued by the local government or regional authority. This raises important questions over the potential of government surveillance into users’ financial activity.
- Financial Stability Risks: CBDCs can introduce new financial risks, especially in the event of a “bank run” where people withdraw funds from banks and convert them into digital currencies.
- New Banking Competition: The availability of digital currencies creates new competition for banks by increasing competition for deposits. This may result in banks reducing funding and lending services to other customers.
- Cyberattack Risks: Centralized digital banking currencies immediately become prime targets for cybercriminals and state-sponsored attacks, creating new and substantial national financial security threats.
CBDCs vs. Cryptocurrencies
Central Bank Digital Currencies share some similarities with cryptocurrency. However, they are very different in several key areas.
Category
CBDC (Central Bank Digital Currency)
Privately-Issued Digital Currency
Issuer
The central bank or government is the sole issuer and authority over CBDCs.
Private companies or decentralized collectives control issuance.
Legal Status
Serves as a form of legal tender and is a direct liability of the central bank, ensuring its value.
Not considered legal tender; its value is often speculative or derived from underlying assets.
Backing/Collateral
Value is backed by a government promissory guarantee, similar to traditional fiat currency.
Value is often asset-backed (e.g., a traditional fiat currency like cash, or a commodity like gold) or algorithmic. Some currencies lack any collateral.
Governance & Control
Governance is centralized, with the central bank maintaining complete control and oversight of both transactions and the currency’s supply.
A private company manages governance or a decentralized protocol. Oversight can vary by organization or entity.
Monetary Policy Tools
Provides an integrated tool for government monetary policy, enabling direct intervention in the economy, such as stimulus distribution or interest rate adjustments.
Operates outside traditional monetary systems with no integration with central bank policy, sometimes complicating economic controls.
Financial Stability
Enjoys frequent financial stability by being backed by the stability of the national economy and robust nationwide safeguards.
Highly volatile and vulnerable to risk factors such as market instability or collapse, exchange attacks, or the loss of value.
Privacy
Privacy can vary by system design, from fully traceable transactions to systems with limited anonymity.
Often pseudonymous with wallet transactions visible on a public ledger, but the user’s real identity is concealed.
User Protections
Users benefit from established consumer protection regulations and anti-fraud measures enforced by the government.
Protections are contingent upon the issuer's policies, code audits, and the platform's reputation.
Use Cases
Primarily used for domestic payments, interbank settlements, and as a tool for programmable government policy.
Popular for cross-border transactions, decentralized finance (DeFi), and peer-to-peer (P2P) payments.
Fraud Threats
Common threats are similar to those in the traditional banking system, including phishing scams, malware, and identity theft.
Threats are more specific to the digital asset space and include smart contract exploits, rug pulls by developers, and fraudulent projects such as pump-and-dump schemes.
Common Fraud Threats in Digital Currency
Digital currency offers an exciting new payment option for individuals, merchants, and person-to-person transactions. However, like all payment methods, it is unfortunately targeted by criminals using various fraud and scam tactics.
Phishing Scams
Digital currencies effectively convert cash to electronic currency. Fraudsters will use phishing attacks to steal or obtain legitimate credentials by posing as trustworthy parties, such as bank staff, law enforcement officials, or even family members.
Investment Scams
Criminals pressure their targets to give them money for a once-in-a-lifetime investment opportunity that promises high returns with little risk. However, in reality, the investment doesn’t really exist or is a Ponzi scheme that eventually collapses when new investors dry up.
Rug Pulls
A “rug pull” is a type of crypto fraud where developers build hype and community over a new digital currency asset they are developing. Next, they abruptly abandon the project, selling off assets and causing the currency’s value to plummet. The fraudsters disappear with the money, leaving investors with worthless assets and no recourse.
Fake Wallets and Exchanges
Fraudsters use social engineering tactics to create fake digital wallets or crypto exchanges that resemble legitimate platforms. This may involve using similar or stolen logos, web designs, and branding. When users attempt to connect their digital wallets to these fake platforms, they unknowingly reveal their login information and passwords, allowing criminals to steal their assets.
Social Engineering Fraud
Social engineering fraud is central to many scams that exploit victims’ trust. Criminals tailor carefully crafted messages, designed to psychologically manipulate targets into sharing sensitive data or transferring money. Common tactics include phishing, smishing, vishing, romance scams, and business email compromise (BEC). Using GenAI, criminals can make their social engineering scams even more convincing with deepfakes or voice cloning.
Account Takeover (ATO) Fraud
Criminals use stolen credentials, malware, and malicious bots to log into other people’s digital wallets. From there, they can make purchases or transfer assets to different accounts they control.
Synthetic Identity Fraud
Criminals use a combination of real and fabricated information to create fake identities and commit new account fraud. If successful, these profiles can bypass KYC checks and allow criminals to launder money from criminal activities.
Physical Threats
While digital currency may only exist electronically, criminals may resort to physical threats and force to steal them. These types of attacks are also known as “wrench attacks” or “$5 wrench attacks” and may involve brutal methods like kidnapping, home invasion, or even torture to coerce owners to transfer assets.5

Building a Safer Digital Currency Future
Digital currencies are a vast leap from traditional payment methods like coins, cash, and cards. While these may be newer payment options, they are still vulnerable to the same fraud tactics that target both organizations and customers.
As currency becomes digital, it’s more important than ever to understand who is behind a transaction and quickly assess their risk level. Feedzai’s AI-powered risk-scoring engine, combined with our behavioral analysis and biometrics capabilities, is an essential tool for keeping digital currency transactions secure.
Digital currencies hold significant promise to help unbanked populations, bolster a nation or region’s local economy, and promote economic independence. However, transactions must remain secure across all possible channels for customers and citizens to realize the full benefits of these currencies. As these currencies expand, it’s never been more essential to ensure real-time risk scoring protections.
Frequently Asked Questions about Digital Currency
What is the difference between CBDCs and cryptocurrencies?
Central Bank Digital Currency, or CBDC, is a digital version of a nation’s fiat currency, issued and controlled by its central bank. Unlike decentralized cryptocurrencies such as Bitcoin, which lack government backing, a CBDC is centralized, maintains a stable value, and is an official liability of the issuing central bank.
How can I identify a cryptocurrency scam?
Scammers frequently try to rush you into investing. Be suspicious of unsolicited messages on social media, fake websites, or individuals impersonating celebrities or well-known companies. Authentic investments will never require payment in cryptocurrency. Always be wary of claims promising high returns with minimal risk.
Are stablecoins safe?
Stablecoins aim for a stable value, often tied to a fiat currency like the US dollar. Though typically less volatile than other cryptocurrencies, they still carry risks. Their safety hinges on the transparency of their reserves and the regulatory framework. Always investigate a stablecoin’s backing and audit reports before use.
How can I secure my digital currency investments?
For substantial investments, use hardware wallets for cold storage. These physical devices safeguard your private keys offline from online threats. Always enable two-factor authentication (2FA) and use strong, unique passwords for online accounts. Remain alert to phishing attempts and never disclose your private keys or seed phrase.
