What are Stablecoins?

Discover the growing world of stablecoins, where digital currency meets stability.

What are Stablecoins?

Recently, the word "stablecoin" has been heard more and more in the cryptocurrency world, especially after major companies like PayPal announced the creation of their own stablecoins, for example.

Stablecoins are a type of cryptocurrency whose value is tied to another asset, such as fiat currency or gold, to maintain a stable and constant value. Unlike more volatile cryptocurrencies such as Bitcoin and Ethereum , stablecoins offer predictability and reliability, making them ideal for transactions and preserving value.

What is a stablecoin?

A stablecoin is a type of cryptocurrency whose value is pegged to a stable asset such as fiat currency (such as the U.S. dollar), gold or different assets. This pegging provides stablecoins with relative stability in value compared to other cryptocurrencies, which can experience significant price fluctuations in short periods of time.

Key characteristics of stablecoins include:

  • Tied to stable assets: The value of a stablecoin is maintained through a direct link to a specific asset or basket of assets. This provides stability in value, unlike bitcoin and other cryptocurrencies whose prices can fluctuate wildly.
  • Reduced volatility: Stablecoins are designed to minimize price volatility, making them an attractive tool for transactions, trading and preserving value.
  • Widespread use: They can be used for cross-border payments, as a medium of exchange on cryptocurrency exchanges, to earn interest in crypto-financial products, and as a store of value.

Why is stability a key feature?

One of the main problems with cryptocurrencies such as Bitcoin is their high volatility, making their use risky for long-term store of value and everyday transactions. The price volatility of cryptocurrencies can lead to significant financial losses in a short period of time, creating a barrier to their widespread adoption as a means of payment.

Stablecoins solve this problem by offering a digital asset whose value remains stable over time. This makes them an ideal choice for everyday transactions, fund transfers, and for use in decentralized financial applications (DeFi) where predictability of value is required.

The stability of stablecoins gives confidence to users and investors, allowing them to avoid the sharp price fluctuations common to many other cryptocurrencies, and makes stablecoins an important element in the cryptocurrency and blockchain ecosystem.

Types of stablecoins

Stablecoins can be categorized by the type of asset they are tied to in order to maintain their stability. This division includes fiat stablecoins, cryptocurrency stablecoins, and algorithmic stablecoins, each with their own unique characteristics, advantages, and challenges.

Fiat Stablecoins

Fiat stablecoins are the most common type of stablecoins whose value is pegged to a fiat currency such as the US dollar, euro, or Japanese yen. Examples of such stablecoins are Tether (USDT), USD Coin (USDC), and Binance USD (BUSD). These stablecoins are backed one-to-one by fiat currencies held in the reserves of the managing organizations.


  • Predictability and stability of value.
  • Widespread acceptance and use in cryptocurrency transactions.


  • The need for trust in the central issuer that manages the reserves.
  • Regulatory risks associated with the management of fiat reserves.

Crypto сollateralized Stablecoins

Crypto сollateralized stablecoins backed by other cryptocurrencies instead of fiat money. An example of such a stablecoin is DAI, which is issued by the MakerDAO platform and backed by ether (ETH). Cryptocurrency holders can pledge their assets as collateral to receive stablecoins.


  • Decentralized provisioning and management without central control.
  • Ability to maintain stability without being tied to fiat currencies.


  • The high volatility of secured cryptocurrencies can threaten the stability of stablecoin.
  • Difficulty in managing and maintaining sufficient collateral.

Algorithmic Stablecoins

Algorithmic Stablecoins - try to maintain their value through algorithmic mechanisms that regulate token supply, without the use of traditional collateral. These stablecoins work by automatically increasing or decreasing the supply of coins on the market in response to changes in price to stabilize their value.


  • Full decentralization and no need for collateral.
  • Flexibility and adaptability to market conditions.


  • Risk of highly unstable performance and potential collapse without traditional collateral.
  • Difficulty in building and maintaining trust in the algorithmic stabilization mechanism.

Each type of stablecoin offers unique approaches to addressing volatility in the cryptocurrency space, while facing its own set of challenges and limitations. Understanding these differences helps users and investors better navigate the world of stablecoins and make informed choices.

Tether (USDT): One of the oldest and most widely used stablecoins, USDT was launched in 2014. This stablecoin is backed by US dollars held in the issuer's reserves and offers a quick and easy way to transfer value in the cryptocurrency world. USDT is used for trading on exchanges, arbitrage, and as a means to store value.

USD Coin (USDC): Launched in 2018 by Circle and Coinbase, USDC is an open-source and fully backed USD stablecoin. This stablecoin is used for transactions, trading, and as value in decentralized finance (DeFi). USDC stands out for its transparency and regular audits of reserves.

Dai (DAI): Unique among stablecoins, Dai is backed not by fiat currencies but by cryptocurrency backed on the MakerDAO platform. DAI seeks to maintain stability against the US dollar using decentralized Ethereum smart contracts, making it one of the most popular stablecoins in the DeFi ecosystem.

Issues and Challenges Analysis:

  • Legal disputes: Tether (USDT) has faced legal challenges and investigations over allegations of insufficient collateral and misleading information about its reserves. The controversy surrounding Tether underscores the need for transparency and reliability in the management of stablecoin reserves.
  • Collateral issues: The importance of accurately and fully backing stablecoins with dollars or other assets is at the forefront after several instances where stablecoin issuers have failed to provide convincing evidence of adequate reserves. This raises questions about the trust and stability of stablecoins in crisis situations.
  • Centralization and transaction controls: Some stablecoins, including USDC, have built-in mechanisms that allow assets to be frozen or transactions to be reversed at the request of law enforcement. This sparks debate about the balance between the need to comply with laws and maintaining decentralization and anonymity in cryptocurrencies.
