Stablecoins are often marketed as the safe middle ground between the volatility of cryptocurrencies and the reliability of fiat currencies.
However, beneath their calm surface lies a growing list of technical, systemic, and security vulnerabilities.
A recent phishing attack that resulted in a $2.6 million loss of USDT has brought these concerns into sharper focus.
While stablecoins may maintain a fixed value, the infrastructure supporting them is highly susceptible to exploitation.
This article explores the hidden risks of stablecoins, combining real-world examples, behavioral insights, and emerging regulatory perspectives.
As the cryptocurrency market continues to evolve, understanding stablecoins’ role in financial stability and their impact on financial security becomes essential for any serious investor.
Key Takeaways

What Are Stablecoins and Why Are They Considered “Safe”?
Stablecoins are digital assets pegged to the value of stable assets like the U.S. dollar, euro, or commodities such as gold.
These coins are designed to offer price stability while retaining the benefits of blockchain-based transactions.
The main categories include fiat-backed stablecoins (e.g., USDT, USDC), crypto-backed (e.g., DAI), and algorithmic stablecoins (e.g., FRAX).
Stablecoins like USDC are commonly used for trading, cross-border payments, remittances, and participation in DeFi platforms.
They promise low volatility compared to cryptocurrencies like Bitcoin and Ethereum, making them attractive for users seeking a secure store of value or a medium of exchange.
However, this perceived stability is only as strong as the mechanisms, reserves, and governance frameworks that support it.
The credibility of a stablecoin often depends on the transparency of its collateralization, especially during periods of market fluctuations.
The $2.6 Million USDT Scam: A Case Study in Investor Risk
In May 2025, a crypto investor was targeted by a double phishing scheme involving a method known as the “zero-transfer” scam.
In this exploit, attackers send a transaction of zero value from a malicious address that visually resembles one the user has previously interacted with.
These spoofed addresses appear in the wallet’s transaction history, often convincing users to reuse them for future transfers.
The victim unknowingly sent $2.6 million worth of USDT to a fraudulent address.
The entire event unfolded within a span of hours, underscoring how quickly and easily such scams can compromise funds.
This incident illustrates that even assets designed for price stability can be embedded in vulnerable ecosystems.
As stablecoins like Tether (USDT) become more widely adopted, attackers increasingly target them using sophisticated social engineering and deception.
Core Hidden Risks of Stablecoins Investors Need to Understand
Phishing and Address Spoofing Attacks
Stablecoin transactions typically rely on self-custody wallets, which place the responsibility for security squarely on the user.
Scams such as address poisoning and zero-value transfers exploit common behaviors, such as copying wallet addresses from transaction histories.
These phishing tactics have surged due to the minimal barriers to executing them and the growing use of stablecoins in high-value transfers.
Even tech-savvy users are at risk when attackers employ advanced spoofing strategies.
Wallet providers and blockchain explorers do not always offer adequate warnings or protective UI design to prevent these types of scams.
Reserve Transparency and Asset Backing Risks
Stablecoins like USDT and USDC are backed by reserves that are supposed to match the circulating supply of tokens 1:1.
These reserves often include assets like U.S. Treasuries, cash equivalents, or commercial paper.
While these instruments are relatively stable, they are not immune to market fluctuations.
The lack of real-time, third-party audits means investors must take issuers at their word.
In past cases, questions have been raised about the composition, accessibility, and liquidity of reserves.
If issuers cannot liquidate their holdings quickly during a redemption surge, the stability of the coin can collapse, potentially undermining financial stability across the broader crypto ecosystem.
De-Pegging and Liquidity Events
De-pegging refers to the scenario where a stablecoin temporarily or permanently deviates from its intended peg.
This risk can stem from sudden demand for redemptions, regulatory actions, or insolvency events at partner banks.
The de-pegging of USDC in March 2023 following the collapse of Silicon Valley Bank is a notable example.
Such events not only disrupt market confidence but can also trigger panic selling and contagion across DeFi protocols that rely on stablecoins as collateral.
Investors holding these coins may face losses if the peg is not swiftly restored.
Regulatory Gaps and Jurisdictional Risk
Stablecoins operate across global markets, but regulations vary significantly by jurisdiction.
Some countries treat them as digital money, others as securities, and some still lack clear classification.
This fragmented landscape allows issuers to operate in regulatory gray areas and exposes users to different levels of risk depending on their location.
Without unified standards on disclosures, audits, and consumer protections, users often have little recourse in the event of fraud, insolvency, or loss of access to funds.
As the use of Tether and other stablecoins expands in both centralized and decentralized markets, regulatory clarity will be a major determinant of investor protection.

Psychological Traps in Stablecoin Investing
The term “stablecoin” itself can create a cognitive bias, leading users to believe they are safe by default.
This perceived safety often results in a lax attitude toward due diligence and wallet hygiene.
Many users assume that because the price doesn’t fluctuate, the risks must be minimal.
Behavioral economists have shown that familiarity and simplicity reduce our perception of risk.
Unfortunately, this complacency makes users more susceptible to scams, poor platform choices, and overexposure to a single asset type.
Investors may even treat stablecoins as safe-haven assets within their broader cryptocurrency investment portfolios, without fully understanding the underlying risks.
On-Chain Data: How Often Do Stablecoin Scams Happen?
According to Chainalysis, crypto scams involving stablecoins accounted for nearly 15% of DeFi-related fraud in 2024.
These scams often target users through phishing links, fake airdrops, and impersonation of trusted platforms.
CipherTrace reported a sharp rise in the use of zero-transfer phishing techniques, with more than 75% growth in such incidents year-over-year.
Stablecoins are particularly attractive to scammers because they are widely used, easily transferable, and typically involved in larger transaction volumes.
The trend indicates that as stablecoin adoption grows alongside cryptocurrency markets, so does the sophistication and frequency of scam attempts.
Risks of Stablecoins in Emerging Markets
Emerging markets with high inflation and capital controls often see heavy reliance on stablecoins for savings, remittances, and everyday transactions.
However, users in these regions may lack access to financial education, legal support, or reliable infrastructure.
In countries like Argentina, Nigeria, and Turkey, stablecoins fill a vital gap, but they also expose users to risks they may not fully understand.
Scammers often take advantage of this by targeting low-literacy regions with wallet drainers, fake crypto apps, and Ponzi-style schemes involving stablecoins.
Tether is one of the most used stablecoins in these markets due to its liquidity and cross-border ease of use.

Legal Liability: Who’s Responsible When Things Go Wrong?
Most stablecoin issuers include legal disclaimers absolving them of liability for losses, thefts, or de-pegging events. This leaves users exposed in the event of a failure.
Cross-border enforcement of crypto-related claims is complex and time-consuming, especially when wallets are pseudonymous.
The decentralized and permissionless nature of blockchain compounds the challenge of legal recourse.
Unless regulation mandates certain protections or guarantees, investors must assume full responsibility for their actions and potential losses.
The lack of legal clarity is a significant concern for anyone making an investment in stablecoins.
Risk Mitigation Tools and Technologies
To reduce exposure, users can employ several technologies and tools:
- Revoke.cash helps users cancel or manage active token permissions.
- Smart contract audit services like Certik or DeFiSafety provide transparency on the safety of DeFi protocols and apps.
- Hardware wallets offer offline protection from phishing and malware.
- Multisig wallets require multiple signatures to approve high-value transactions, reducing single point-of-failure risks.
While no solution is perfect, layering multiple tools provides a higher level of protection and increases the cost of attack for scammers.
This is especially important when stablecoins serve as a key component of your crypto investment strategy.
How to Protect Yourself from Stablecoin-Related Risks
- Secure Your Wallet: Use cold storage, strong passwords, and hardware devices.
- Verify Everything: Always double-check recipient addresses and contracts before confirming transactions.
- Do Your Research: Understand how a stablecoin is backed, who the issuer is, and whether reserves are audited.
- Diversify: Spread your holdings across multiple stablecoins and platforms to reduce exposure to a single point of failure.
- Use Reputable Platforms: Choose wallets and exchanges with strong reputations and active security measures.
Incorporating stablecoins like USDC into your cryptocurrency investment portfolio can be practical, but only if you fully understand the associated risks and actively manage your exposure.
The Future of Stablecoin Safety: Is Regulation the Answer?
Efforts like the EU’s Markets in Crypto-Assets (MiCA) regulation and U.S. legislative proposals aim to bring structure to the stablecoin sector.
These frameworks seek to enforce minimum reserve standards, mandate public disclosures, and establish licensing regimes for issuers.
Central Bank Digital Currencies (CBDCs) may eventually offer a more secure alternative by embedding regulatory oversight into the design.
In parallel, industry efforts are underway to build more transparent, audited, and secure stablecoins through on-chain proof-of-reserve mechanisms and open governance.
Still, meaningful protection depends on enforcement and adoption, and until global standards are implemented, users must remain cautious.
Regulation that addresses both investor protection and macro-level financial stability will be key to the future of this sector.

Conclusion
Stablecoins are foundational to many aspects of the crypto economy, but they carry risks that are not always visible or well-understood.
The $2.6 million USDT phishing incident underscores that security failures are more likely to occur at the user interaction level than through price volatility alone.
Understanding the risks of stablecoins, from technical exploits and psychological traps to systemic vulnerabilities, is essential for any serious crypto investor.
By practicing good security hygiene, diversifying assets, and staying informed about regulation, users can better protect themselves while benefiting from what stablecoins offer.
