What Are Stablecoins and Their Purpose?
Similar to fiat currencies, stablecoins are a type of cryptocurrency designed to maintain a relatively stable price. They serve as a hedge for investors and facilitate payments. Note that stablecoin prices are not absolutely stable—they can fluctuate, but their volatility is significantly lower compared to non-stablecoins like BTC or ETH.
Before stablecoins existed, several challenges arose, such as merchants hesitating to accept cryptocurrencies and investors avoiding long-term holdings due to the risk of depreciation. For example: Imagine you're a bakery owner who earns 1 BTC worth $10,000 today. Tomorrow, its value might drop to $5,000 due to market volatility. While it could also rise, most businesses cannot tolerate such roller-coaster price swings.
To address the high volatility of cryptocurrencies, solutions were sought. In 2014, Tether launched the first stablecoin, USDT. In 2015, MakerDAO introduced DAI. By 2018, Paxos and Gemini released Paxos Standard (PAX) and Gemini Dollar (GUSD). The DeFi boom in 2020 further accelerated the emergence of stablecoins.
Types of Stablecoins and Their Characteristics
According to CoinMarketCap, as of August 10, 2023, there are 148 stablecoins. Based on their underlying mechanisms, they can be categorized into four main types:
| Type | Collateral | Features | Examples |
|---|---|---|---|
| Fiat-backed | USD, EUR, GBP, etc. | Centralized, issuer risk | USDT, USDC, BUSD |
| Crypto-collateralized | BTC, ETH, etc. | Decentralized, liquidation risk | DAI, sUSD |
| Commodity-backed | Gold, precious metals | Centralized, asset-backed | PAXG, XAUT |
| Algorithmic | None | Algorithmic supply adjustments | USDD, AMPL, FRAX |
Advantages and Disadvantages of Stablecoins
Stablecoins combine blockchain technology with fiat-like stability, offering unique benefits but also facing certain limitations.
Advantages:
- Price Stability: Lower volatility makes them ideal for risk-averse investors.
- Cross-Border Payments: Faster and cheaper transactions compared to traditional forex.
Disadvantages:
- Reserve Transparency: Doubts persist about whether reserves (e.g., USDT) are fully backed.
- Centralization Risks: Regulatory actions can impact fiat-backed stablecoins (e.g., BUSD halt by SEC).
- Liquidation Risks: Crypto-backed stablecoins may face forced sales if collateral ratios fall.
Future Trends and Predictions for Stablecoins
Despite past failures (e.g., UST depegging), stablecoins remain vital due to crypto market volatility. Their total market cap exceeds $120 billion (10% of the crypto market), with USDT and USDC ranking among the top cryptocurrencies.
As blockchain adoption grows, demand for stablecoins will rise, though some may fail. Investors should diversify holdings across types (e.g., USDT + DAI) to mitigate risks.
Investment Strategies for Stablecoins
Stablecoins trade like forex—low volatility necessitates large capital or leverage (though few platforms offer leveraged trading). Strategies include:
- Arbitrage: Buy low during temporary depegging (e.g., USDC during the SVB crisis).
- Yield Farming: Earn interest via lending or liquidity pools (higher rewards for new stablecoins).
