Stablecoin Beginner's Guide: Learn About Stablecoins from Scratch

If you're just getting started with cryptocurrencies, the term 'stablecoin' may sound a bit unfamiliar. But don't worry, this simple guide will use easy-to-understand language to help you understand what stablecoins are, why they're important, how they work, and some common questions and answers.

What are stablecoins?

In simple terms, a stablecoin is a type of 'stable cryptocurrency'. Its value is usually pegged to a real-world asset, such as the US dollar, euro, or gold. Why do this? Because regular cryptocurrencies (like Bitcoin and Ethereum) have too much price volatility, while stablecoins aim to maintain a stable value (usually pegged 1:1 to the US dollar), allowing people to trade and store value without worrying about sudden price changes.

Why are stablecoins important?

Reducing Volatility Risk:

For example, if you hold Bitcoin and the market suddenly crashes. If you promptly convert Bitcoin to stablecoins, you can avoid losses.

Convenient for Daily Transactions:

Stablecoins are more suitable for payments, cross-border transfers, or storing assets due to their price stability, unlike other cryptocurrencies that may cause concerns over value volatility.

More Efficient Global Payments:

Through blockchain technology, stablecoins can achieve fast, low-cost international transfers, eliminating the cumbersome procedures and high fees associated with traditional banks.

Gateway to the DeFi World:

Stablecoins are the foundational assets for many DeFi (Decentralized Finance) platforms, allowing for participation in lending, staking, and liquidity mining to earn returns.

How do stablecoins work?

The core of stablecoins is 'having stable supporting assets'. Just like how paper money is backed by national credit, stablecoins also have different collateral mechanisms to maintain their value stability.

Fiat Currency Support:

For example, Tether (USDT) and USD Coin (USDC), which are backed by actual dollar reserves. In simple terms, the issuer deposits an equivalent amount of dollars in the bank to ensure that every USDT or USDC has real asset backing.

Cryptocurrency Support:

For example, Dai (DAI), which relies on cryptocurrencies (like Ethereum) as collateral instead of dollars. To ensure safety, these types of stablecoins usually use an 'over-collateralization' approach, such as collateralizing $150 worth of Ethereum to support $100 worth of stablecoins.

Commodity Support:

Some stablecoins, such as gold-backed stablecoins, are backed by reserves of gold, silver, and other commodities.

Algorithm Support:

This method is somewhat special, as it does not rely on actual asset collateral but instead automatically adjusts the supply and demand of stablecoins through algorithms and smart contracts to maintain price stability (such as TerraUSD, despite its failure).
