What are Stablecoins?

A stablecoin is a digital currency designed to maintain a steady value by linking it to a real-world asset like gold or a traditional currency. This connection to a tangible asset instills confidence in its price. Stablecoins are favored by both regular users and institutions in the cryptocurrency world because they offer reliability. These coins aim to create a dependable environment, reducing the unpredictable nature of digital assets. They combine the security and decentralization of cryptocurrencies with the stability of fiat currencies. Essentially, a stablecoin is a type of cryptocurrency that’s meant to stay at a consistent value, tied to a reference asset, which could be fiat money, commodities, or another cryptocurrency. While the idea is to maintain a 1:1 value with the reference asset, in reality, some stablecoin issuers may not always hold enough reserves to guarantee this stability.

A Brief History of Stablecoins

The cryptocurrency world is still young, and digital assets don’t have much trading activity, which makes their prices go up and down a lot. This unpredictability is a problem because it makes using cryptocurrencies in everyday life difficult.

To fix this, stablecoins were invented. Stablecoins are a type of cryptocurrency that uses technology to keep their value stable by tying them to something real, like a regular currency.

The very first stablecoins, called BitUSD and NuBits, were created in 2014. They were linked to other cryptocurrencies instead of regular money. BitUSD was made by Dan Larimer (who later worked on EOS) and Charles Hoskinson (who later worked on Cardano). But BitUSD didn’t always stay worth the same as the US dollar, which caused problems.

NuBits, on the other hand, was created in 2014 and used a system called Seigniorage, but it lost most of its value over time, dropping to just a few cents.

Tether, also known as USDT, is a stablecoin that you might have heard of. It came out in 2015 and was initially called RealCoin. Tether is connected to real assets and became popular, but it faced issues like a big hack in 2017 and claims of being used to manipulate Bitcoin prices in 2017.

In simple terms, stablecoins are created to make cryptocurrencies more stable and usable in everyday life, but they’ve had their share of problems along the way.

How do Stablecoins Work?

At its core, when an exchange has a stablecoin tied to a regular currency (like the dollar), it keeps one dollar in reserve for every stablecoin in circulation. This link ensures that the stablecoin’s value is directly connected to that currency, allowing stablecoin holders to potentially exchange their stablecoins for regular currency at a one-to-one rate.

While most Stablecoins in circulation are connected to traditional currencies, there are also stablecoins linked to other assets, such as:

Stablecoins tied to valuable resources like gold, as seen with Digix Gold.

Stablecoins connected to different cryptocurrencies, with Dai being a well-known example.

Algorithm-based stablecoins, also known as Non-Collateralized Stablecoins, like Ampleforth or AMPL token.

Regardless of the specific mechanisms used for these various stablecoins, their ultimate goal is the same: to provide confidence to stablecoin holders in the stability of the asset’s value.

Types of Stablecoins 

There are four main types of stablecoins:

Fiat-Backed Stablecoins: These are tied to traditional currencies like the U.S. dollar, with each stablecoin having a one-to-one value ratio with the fiat currency. They maintain stability by holding an equivalent amount of the fiat currency in reserve. Examples include Tether (USDT) and USD Coin (USDC).

Commodity-Backed Stablecoins: These use commodities such as gold or real estate as collateral to ensure stability. Gold is a common choice. Examples include Paxos Gold (PAXG) and Tether Gold (xAUT), allowing you to be part of the gold market without owning physical gold.

Crypto-Backed Stablecoins: They use cryptocurrencies as collateral and rely on blockchain smart contracts to maintain stability. Users lock their cryptocurrency in a smart contract in exchange for an equivalent value in stablecoins. DAI is a popular example.

Algorithmic Stablecoins: These unique stablecoins don’t rely on collateral. Instead, they use algorithms to adjust token supply based on market conditions. When the price exceeds the target, they issue more tokens to lower the price, and when it falls below the target, they reduce supply to raise the price.

Features of Stable Coins

Stablecoins are a type of cryptocurrency designed for price stability, often linked to assets like fiat currencies (e.g., US dollars), commodities (e.g., gold), or other cryptocurrencies (e.g., Bitcoin). They provide a consistent value, unlike volatile cryptocurrencies like Bitcoin or Ethereum. Key features include:

Price Stability: Stablecoins maintain a steady value close to their pegged asset, reducing price volatility.

Pegging Mechanism: Stablecoins use mechanisms like fiat collateralization, crypto collateralization, or algorithms to maintain their peg.

Transparency: Many stablecoin projects offer real-time audits and transparency to build trust among users.

Liquidity: Stablecoins are highly liquid, suitable for trading, remittances, and conversions to other assets.

Cross-Border Transactions: They enable cost-effective and fast cross-border transactions.

Decentralization: Some operate on decentralized blockchains for transparency and censorship resistance.

Use Cases: Stablecoins serve various purposes, from store of value to medium of exchange and international transfers.

Regulatory Compliance: Some issuers adhere to local and international regulations for stability and legality.

Accessibility: Accessible to anyone with an internet connection, promoting financial inclusion.

Volatility Hedge: Used by traders and investors to hedge against cryptocurrency volatility.

Remember that the stablecoin landscape evolves, so users should research and exercise caution, as stability mechanisms can differ among stablecoins.

Fiat Currency

Fiat currency is government-issued money that is not backed by a physical commodity, such as gold or silver. Its value is derived from the government’s decree that it is legal tender, meaning it must be accepted as a form of payment for goods and services within the issuing country.

Features of Fiat Currency

Legal Tender: Fiat currency is recognized and accepted as a valid form of payment within the issuing country.

Government Issued: Fiat currency is issued and regulated by the government or central bank of a country.

Physical and Digital Forms: Fiat currency exists in both physical forms (such as banknotes and coins) and digital forms (such as electronic bank balances and digital payment methods).

Widely Accepted: Fiat currency is universally accepted within the country of issuance.

Stability: Governments and central banks work to maintain price stability and control inflation.

Legal Protections: Fiat currency is protected by law, and counterfeiting is a criminal offense.

Monetary Policy: Central banks can influence the money supply and interest rates to control the economy’s stability and growth.

National Identity: The design and symbols on banknotes and coins often reflect the culture, history, and national identity of the issuing country.

Divisibility: Fiat currency is easily divisible into smaller denominations.

Portability: Fiat currency is lightweight and easy to carry.

Anonymity: Cash transactions offer a level of privacy and anonymity.

Exchange Rate: Fiat currencies can be exchanged for other foreign currencies in international foreign exchange markets.

Store of Value: Fiat currency can be used as a store of value for the short term.

Acceptance of Debit and Credit Cards: Fiat currency serves as the underlying medium for electronic payment methods like debit and credit cards.

Legal Regulations: Governments enact regulations to monitor and control financial institutions and prevent illegal activities involving fiat currency.
