What Are Stablecoins?


Within the realm of cryptocurrencies, stablecoins serve as a unique subset of crypto assets. They are tethered to other assets, such as fiat currencies or precious metals, to ensure price stability. This design provides users with a means to mitigate the inherent volatility commonly associated with traditional crypto markets.

Stablecoins can be categorized into three main types: fiat-backed, crypto-backed, and algorithmic. Each variant follows distinct mechanisms to maintain their stability. The growing practicality and significant market capitalization of stablecoins have garnered the attention of regulators. As a result, regulatory bodies are now closely examining these assets.

Contrary to the popular notion that cryptocurrencies are inherently volatile, stablecoins challenge this perception. By offering a fixed price, they cater to the demand for blockchain-enabled currencies that exhibit stability. If you have yet to explore the realm of stablecoins in your trading or investment endeavors, delving deeper into their attributes, advantages, and limitations would be worthwhile.

What Is a Stablecoin in Cryptocurrency?

Within the realm of digital assets, stablecoins emerge as a viable solution for tracking the value of fiat currencies or other underlying assets. These assets offer tokens linked to the likes of the dollar, euro, yen, as well as commodities like gold and oil. By leveraging stablecoins, individuals can securely transfer value at a fixed price on decentralized peer-to-peer blockchain networks while effectively managing their profits and losses.

The historically volatile nature of cryptocurrencies like Bitcoin (BTC), Ether (ETH), and other alternative coins has presented both opportunities for speculation and drawbacks. Notably, their volatility hinders seamless everyday transactions. For instance, a merchant accepting $5 worth of BTC for a coffee may encounter a 50% decrease in the value of their BTC the next day, creating complications when operating a business that embraces cryptocurrency payments.

In the past, crypto investors and traders had no avenue to shield themselves from volatility or lock in profits without converting their crypto back into fiat. However, the advent of stablecoins introduced a straightforward solution to address these concerns. Today, individuals can readily navigate the realms of crypto volatility by engaging with stablecoins like TrueUSD (TUSD), enabling smoother transitions between the crypto and traditional financial landscapes.

How Do Stablecoins Functionate?

The creation of a coin that closely tracks the price or value of another asset necessitates the implementation of a pegging mechanism. Various approaches exist, most of which rely on collateralization with another asset. While some methods have proven more successful than others, it's important to note that a guaranteed peg remains elusive.

Fiat-Backed Stablecoins

In the realm of stablecoins, the fiat-backed variant holds a fiat currency, such as USD or GBP, as reserves. For instance, each unit of TUSD is backed by $1 held in collateral. This allows users to seamlessly convert their fiat into stablecoins and vice versa, maintaining a steady pegged rate.

Crypto-Backed Stablecoins

Similar to their fiat-backed counterparts, crypto-backed stablecoins leverage collateralization. However, instead of relying on traditional currency reserves, cryptocurrencies serve as collateral. Given the inherent volatility of the crypto market, crypto-backed stablecoins typically over-collateralize their reserves to mitigate price fluctuations.

Smart contracts play a pivotal role in managing the minting and burning of crypto-backed stablecoins, bolstering reliability through independent contract audits by users. Some crypto-backed stablecoins operate under the purview of Decentralized Autonomous Organizations (DAOs), enabling the community to vote on project changes. Individuals can choose to engage with the decision-making process or trust the DAO's expertise.

To illustrate, let's consider an example. Minting 100 DAI pegged to USD requires providing $150 worth of crypto as collateral, establishing a collateralization ratio of 1.5x. Once you possess DAI, its utilization becomes flexible. It can be transferred, invested, or held as is. If you wish to reclaim your collateral, repaying the 100 DAI is necessary. However, if your collateral's value drops below a specified collateral ratio or the loan's value, liquidation becomes imminent.

When the stablecoin falls below $1, incentives are created for holders to return their stablecoin in exchange for collateral. This reduces the coin's supply, subsequently elevating the price back to $1. Conversely, when the stablecoin surpasses $1, users are incentivized to create more tokens, augmenting the supply and driving the price downward. While DAI exemplifies this process, all crypto-backed stablecoins rely on a fusion of game theory and on-chain algorithms to incentivize price stability.

Algorithmic Stablecoins

Diverging from the aforementioned models, algorithmic stablecoins adopt an alternative approach by eliminating the need for reserves. Instead, supply management is entrusted to algorithms and smart contracts. This model is comparatively rare among stablecoins and entails greater operational complexity.

In essence, an algorithmic stablecoin system adjusts the token supply based on fluctuations in the price relative to the tracked fiat currency. Techniques like locked staking, burning, or buy-backs may be employed to decrease the token supply if the price falls below the targeted fiat value. Conversely, if the price surpasses the fiat value, new tokens enter the circulation to alleviate the stablecoin's value.

What Are the Advantages of Stablecoins?

In the realm of cryptocurrency, stablecoins have emerged as dynamic and formidable tools for investors, traders, and crypto enthusiasts alike. Their exceptional qualities encompass a range of strengths, including:

Enabling Seamless Day-to-Day Payments

Stability holds immense value for businesses and individuals seeking to engage in everyday transactions. Unlike volatile cryptocurrencies, stablecoins have established a solid track record of maintaining their peg, rendering them suitable for widespread use in daily payment scenarios.

Leveraging Blockchain Advantages

Built on the foundation of blockchain technology, stablecoins possess unparalleled flexibility. With a compatible crypto wallet, individuals can effortlessly send stablecoins to recipients globally. Furthermore, the immutable nature of blockchain ensures minimal risk of encountering double-spending or fraudulent transactions. These qualities amplify the versatility of stablecoins, making them a preferred choice for many.

Hedging Portfolios and Reducing Risk

Traders and investors can effectively utilize stablecoins to hedge their portfolios. By allocating a portion of their portfolio to stablecoins, they can mitigate overall risk. This strategic approach fortifies the portfolio's resilience against market price fluctuations while providing readily accessible funds for seizing lucrative opportunities. Additionally, during market downturns, converting crypto assets into stablecoins allows for advantageous repurchases at lower prices (commonly known as shorting). Conveniently, stablecoins enable seamless entry and exit from positions without the need to withdraw funds from the blockchain.

What Are the Disadvantages of Stablecoins?

While stablecoins possess the potential to foster widespread cryptocurrency adoption, it is crucial to recognize their inherent limitations. These considerations include:

The Uncertainty of Peg Maintenance

Despite the commendable track record of certain prominent stablecoin projects, it is important to acknowledge that not all stablecoins guarantee a steadfast peg. Instances of failed projects have underscored the vulnerability of stablecoins, as persistent challenges in maintaining their peg can lead to substantial devaluation.

Transparency Challenges

Full transparency is not universally practiced among stablecoins. While some projects provide regular attestations, comprehensive public audits are not always released. The responsibility of conducting audits often lies with private accountants employed by the stablecoin issuers.

Centralization Concerns in Fiat-Collateralized Stablecoins

Compared to other cryptocurrencies, fiat-collateralized stablecoins tend to exhibit higher levels of centralization. Typically, a central entity assumes the role of holding the collateral, potentially subjecting it to external financial regulations. This concentration of control by the entity raises the importance of trusting the issuer's ability to maintain the claimed reserves.

Community Reliance in Crypto-Collateralized and Uncollateralized Stablecoins

The functionality of crypto-collateralized and uncollateralized stablecoins relies heavily on their respective communities. It is common for crypto projects to adopt open governance mechanisms, granting users a voice in the project's development and operations. Consequently, active participation or trust in the developers and community becomes essential for responsible project management.

Examples of Stablecoins

Crypto-Backed Stablecoin: MakerDAO (DAI)

MakerDAO introduces DAI as a crypto-backed stablecoin operating on the Ethereum blockchain. Its primary purpose is to mirror the value of the US dollar (USD). DAI's management falls under the jurisdiction of the MakerDAO community, with governance decisions influenced by the MKR token holders. MKR tokens grant users the ability to propose and vote on modifications to the project's framework. To address crypto's inherent volatility, DAI is designed to be over-collateralized. Users engage in Collateralized Debt Positions (CDPs) that manage their collateral, all facilitated through the utilization of smart contracts.

Fiat-Backed Stablecoin: TrueUSD (TUSD)

TrueUSD stands as an independently verifiable stablecoin pegged to the US dollar. Notably, it holds the distinction of being the first stablecoin to programmatically control the minting process while ensuring instant on-chain verification of off-chain USD reserves. TUSD implements Chainlink Proof of Reserve to actively monitor its reserves, allowing holders to autonomously validate the backing of their TUSD tokens by the USD held in reserve.

Are Stablecoins Regulated?

The global attention of regulators has been drawn to stablecoins, which offer a distinct combination of fiat and cryptocurrency elements. Apart from their speculative appeal, stablecoins serve various practical purposes, such as enabling swift and cost-effective international transactions. Certain nations are even exploring the creation of their own stablecoin ventures. As stablecoins fall within the cryptocurrency category, they are expected to be subject to the same regulatory framework as other crypto assets in your local jurisdiction. Furthermore, obtaining regulatory approval may be necessary for stablecoin issuance backed by fiat reserves.


In today's investment landscape, it's rare to encounter an investor or trader who hasn't engaged with stablecoins at some stage. These digital assets are commonly held within crypto exchanges, allowing traders to swiftly capitalize on emerging market opportunities. Additionally, stablecoins offer a convenient means to enter and exit positions without the need to convert to fiat currency. Beyond trading and investment, stablecoins have found utility in facilitating payments and international transfers.

Nevertheless, it's crucial not to underestimate the associated risks, despite stablecoins being a vital component of the crypto ecosystem and contributing to the emergence of a novel financial paradigm. Instances of stablecoin projects experiencing peg failures, insufficient reserves, and legal disputes have come to light. While stablecoins offer remarkable versatility, it's essential to acknowledge their inherent crypto nature and the associated risks. Mitigating these risks can be achieved through portfolio diversification, but conducting thorough research prior to investment or trading is paramount. Moreover, it is advisable to only invest amounts that you are prepared to lose.
