In this guide, you’ll learn what stablecoins are, how they work, the main types available, and why they are essential for both trading and everyday crypto use.

Basic Definition of a Stablecoin

A stablecoin is a cryptocurrency designed to keep a stable value, usually pegged to fiat currencies like the U.S. dollar or euro, or to commodities such as gold. This makes them a safe and reliable alternative for both investors and businesses.

The first stablecoin appeared in 2014 and quickly gained traction. Stablecoins offer security during volatile market conditions while taking advantage of blockchain speed and transparency. Initially, they were used mainly for trading on exchanges that lacked fiat pairs, but today they are widely used in DeFi platforms, payment systems, and other financial applications.

As of July 2025, the total stablecoin market capitalization exceeds $261 billion, dominated by Tether (USDT) and USD Coin (USDC).

Main Types of Stablecoin

Stablecoins can be grouped based on the mechanisms they use to maintain price stability. Each model comes with different benefits and risks.

1. Fiat-Backed Stablecoin

These are the most common type of stablecoins. Each token is backed by traditional currency reserves like U.S. dollars or euros. For example, one USDT is always equal to one U.S. dollar.

• Fully backed by fiat reserves held in banks.

• Regular audits confirm the collateralization.

• Can be purchased or redeemed directly for fiat.

• Examples include USDT, USDC, and BUSD.

2. Crypto-Backed Stablecoin

These stablecoins are backed by other cryptocurrencies as collateral. Because crypto assets are volatile, they are usually over-collateralized.

• $1,000 worth of ETH might back $500 worth of stablecoins.

• Smart contracts automatically adjust supply and collateral levels.

• Decentralized protocols manage the reserves instead of companies.

• Examples include DAI and sUSD.

3. Algorithmic Stablecoin

Algorithmic models maintain stability without holding any reserves. Instead, they use automated supply and demand adjustments to keep the price close to the target value.

• When price rises above $1, new tokens are minted.

• When price falls below $1, tokens are burned or supply is reduced.

• These systems do not rely on collateral but are riskier.

• Examples include Ampleforth (AMPL) and the now-defunct TerraUSD (UST).

4. Commodity-Backed Stablecoin

These are backed by physical assets like gold, silver, or oil. They allow investors to gain exposure to commodities via blockchain.

• Each token represents ownership of a specific quantity of a commodity.

• Provide a digital way to invest in physical assets without storage costs.

• Examples include PAX Gold (PAXG) and Tether Gold (XAUT).

5. Hybrid and Seigniorage Models

Hybrid stablecoins combine collateralized and algorithmic mechanisms. Some use seigniorage-style systems that adjust supply algorithmically to maintain stability.

• They may hold partial reserves or none at all.

• Highly experimental and carry greater systemic risk.

What Is USDT (Tether)?

USDT (Tether) is the most widely used fiat-backed stablecoin. Each token equals roughly one U.S. dollar and is backed by Tether Limited’s reserves. USDT acts as a safe haven during crypto market volatility and enables seamless trading between digital assets.

Users can transfer Tether through blockchain networks and store it in ERC-20 compatible wallets safely and easily.

How Stablecoins Work

Stablecoins maintain a stable price using several mechanisms:

• Reserve Mechanisms: Fiat-backed tokens are supported by cash or equivalent assets.

• Smart Contracts: Algorithmic and crypto-backed types use code to control supply and maintain equilibrium.

• Price Adjustment Systems: Token supply increases or decreases to stabilize price movements.

Key Use Cases

• Everyday Payments: Used for purchasing goods and services without price volatility.

• DeFi Applications: Serve as collateral in lending, staking, and liquidity pools.

• Cross-Border Transactions: Enable cheaper and faster global money transfers.

• Investment and Savings: Provide a stable store of value during market downturns.

Advantages of Stablecoins

• Low Volatility: Protect investors from market swings.

• Fast and Low-Cost Transactions: Ideal for peer-to-peer and cross-border payments.

• DeFi Integration: Used across lending, yield farming, and liquidity protocols.

• Access to Commodities and Fiat: Simple exposure to gold or USD without intermediaries.

• High Liquidity: Most trading pairs use stablecoins like BTC/USDT or ETH/USDC.

Disadvantages and Risks

• Counterparty Risk: Issuers may lack full reserves or fail to honor redemption.

• Centralization: Fiat-backed stablecoins depend on trust in a single company.

• Algorithmic Instability: May lose their peg in extreme market conditions.

• Regulatory Risk: Subject to freezes, sanctions, or government intervention.

• De-Pegging: Occurs when the stablecoin’s value deviates from its target asset.

Most Popular Stablecoins

The leading stablecoins in 2025 include:

• Tether (USDT) – the largest by trading volume.

• USD Coin (USDC) – known for transparency and regulatory compliance.

• Dai (DAI) – decentralized and backed by Ethereum collateral.

• PAX Gold (PAXG) – pegged to physical gold.

2025 Outlook and Future Trends

As of 2025, the global stablecoin market surpasses $261 billion, showing continued growth and institutional adoption.

• CBDCs (Central Bank Digital Currencies): Expected to coexist and integrate with stablecoins for efficient cross-border settlements.

• Corporate Adoption: Companies are increasingly using stablecoins for payments and reserves.

• Regulatory Focus: Authorities are developing frameworks for transparency, auditing, and investor protection.

The stablecoin giant has launched XAUt0, an omnichain version of its gold-backed token XAUt, on TON (The Open Network), marking a new chapter in digital precious metals.

A New Standard in Gold Investing

Built on LayerZero’s “Omnichain Fungible Token” standard, XAUt0 enables seamless transfers across blockchains without using wrapping mechanisms or middlechains. This technical leap allows broader and more flexible access to digital gold.

XAUt, available only on Ethereum, is currently the largest gold-backed stablecoin by market cap at $832 million, closely followed by Pax Gold at $811 million. Tether backs the token with over 7.7 tons of physical gold stored in a Swiss vault, according to its Q1 2025 attestation.

The move follows Tether’s launch of USDt on the TON network earlier in 2024 and mirrors the structure of USDT0, its omnichain dollar-pegged token that spans multiple chains through Optimism’s Superchain ecosystem.

Gold Prices Surge Amid Global Uncertainty

Gold prices have surged in 2025, driven largely by economic instability and escalating trade tensions. As of May 30, gold traded at $3,304 per ounce — a 29.5% increase from the previous year.

Gold ETFs have also performed strongly, with the top eight funds gaining over 25% year-to-date. Tether’s XAUt0 is set to compete with such instruments, offering digital asset investors a new way to access gold’s stability in turbulent times.

Until March 31, Tokens Can Be Converted

Crypto.com will stop trading USDT and nine other tokens as of January 31. However, users will have until March 31, 2025 to withdraw or convert these tokens into MiCA-compliant assets. Any tokens not converted after this date will be automatically converted by the exchange into MiCA-compliant stablecoins or assets equivalent in value.

Crypto.com’s representative stated that this process is an important step to protect users and ensure full compliance with the regulatory framework.

Which Tokens Will Be Delisted?

Among the tokens that Crypto.com will delist are the following:

• Tether (USDT)
• Wrapped Bitcoin (WBTC)
• Dai (DAI)
• Pax Dollar (PAX)
• Pax Gold (PAXG)
• PayPal USD (PYUSD)
• Crypto.com Staked ETH (CDCETH)
• Crypto.com Staked SOL (CDCSOL)
• Liquid CRO (LCRO)
• XSGD (XSGD)

These tokens are being delisted in line with the European Securities and Markets Authority’s (ESMA) announcement to limit non-MiCA-compliant stablecoins as of January 31, 2025.

Expanding Delist Trend for Tether (USDT)

Crypto.com’s delisting of USDT is one of the latest developments in the process of European exchanges and service providers adapting to MiCA regulations. Coinbase had delisted USDT in October 2024 on the grounds that it was not MiCA-compliant . Coinbase had given its customers the option to convert their USDT into MiCA-compliant stablecoins, specifically Circle’s USDC.

With MiCA in full effect, many crypto asset service providers in Europe have obtained or are working to obtain MiCA licenses. Crypto.com is also in the process of obtaining a license in Malta.

The Competition Between USDT and Its Rivals

USDT is the largest stablecoin in the market with a market capitalization of $139 billion. However, its rival USDC, which benefits from MiCA compliance, is currently in second place with a market capitalization of $52 billion. Circle’s USDC was approved as MiCA-compliant in July 2024, enabling the USDC to gain acceptance in the European market.

Impact of MiCA Regulations on the Industry

MiCA regulations aim to make the operations of crypto asset service providers more transparent and compliant. However, the fact that the market’s largest stablecoins, especially USDT, are not covered by MiCA may affect investors’ preferences. After March 31, USDT is expected to be completely abolished in Europe, and the impact of this on the market is a matter of curiosity.

Crypto.com’s move is seen as an important milestone on the road to compliance with MiCA regulations. However, these changes could reshape the dynamics of the cryptocurrency market.
