BTC/USDT and ETH/USDC show how major cryptocurrencies are priced using stable, dollar-pegged assets.
Stablecoin-quoted pairs make crypto trading smoother by reducing volatility in price measurement.
Understanding trading pairs improves clarity in market movements and overall crypto strategy.
A crypto trading pair shows the value of one cryptocurrency in terms of another. In a pair like BTC/USDT, BTC (Bitcoin) is the base asset and USDT (a dollar-pegged stablecoin) is the quote asset. The number quoted for BTC/USDT means how many USDT units are required to buy one BTC. These pairs allow direct swapping of assets rather than converting back to fiat currency every time, so traders can move from one digital asset to another smoothly.
Stablecoins, especially those pegged to the US dollar, have become dominant as quote currencies in crypto markets. They offer a relatively stable reference in a highly volatile asset class, so trading pairs frequently use a stablecoin instead of another highly volatile token.
In 2025, the stablecoin market was estimated at approximately $300 billion, and the two major stablecoins, USDT and USDC, controlled more than 90% of the stablecoin market capitalization. This dominance helps them function as the quote leg in many trading pairs.
The blockchain of a major platform recorded stablecoin transaction volumes of $2.82 trillion in October alone. This resulted in a 45% increase compared to the previous month.
The pair BTC/USDT is the flagship crypto market for several reasons. Bitcoin paired with a dollar-linked stablecoin conveniently links a crypto and a dollar-denominated asset. In October 2025, Bitcoin reached $126,000 before dropping down to $90,000.
This shows how important the BTC/USDT pair is. It aggregates global demand for Bitcoin into a market that uses a widely accepted stablecoin as its quote asset. Deep liquidity and strong global participation tighten the spreads (difference between buy and sell), making it efficient for large trades and price discovery across the market.
While BTC/USDT dominates the broad market, ETH/USDC is important within the Ethereum network and regulated-friendly platforms. The base asset is Ether (ETH) and the quote asset is USD Coin (USDC), another major dollar-pegged stablecoin.
Over recent months, stablecoin settlement activity on the Ethereum network soared, reflecting that many protocols use stablecoins for payments, lending, cross-border transfers and swapping.
This makes ETH/USDC a popular pair when users want exposure to Ethereum while keeping their point of reference in a stablecoin aligned with the dollar. It also appeals to institutions and users in compliance-sensitive jurisdictions.

The structure of available trading pairs defines how capital can move through the crypto market. For example, if a trader holds a smaller token and wants to rotate into Bitcoin, they may go from small-token/USDT to BTC/USDT. If one wants exposure to ETH and then to other altcoins, they may use ETH/USDC.
More than a thousand trading pairs are available on large exchanges, with many quoted in USDT or USDC. This dense network enables cross-asset strategies (such as altcoin to altcoin via a major pair), arbitrage between different quote assets (for instance BTC/USDT versus BTC/USDC), and hedging by moving into a stablecoin quote when volatility spikes.
October 2025 featured a major market event where Bitcoin fell sharply after a risk shock. During that period stablecoin-quoted pairs provided liquidity and channels for capital exit and re-entry.
The increasing importance of stablecoin-quoted pairs has drawn attention from regulators and global institutions. In 2025, legislation in major jurisdictions has begun treating stablecoins as more than just crypto tokens: they are being integrated into financial infrastructure and are subject to oversight regarding reserves, auditing and redemption rights. This reinforces their role as quote assets in trading pairs.
The sudden increase in stablecoin transaction volumes, especially on major blockchains, shows that such assets are deeply embedded in digital finance. The extraordinary monthly volume figures also raise focus on liquidity, settlement risk and regulatory compliance within the stablecoin ecosystem.

Trading pairs are the currencies of exchange inside crypto markets. Pairs like BTC/USDT and ETH/USDC do more than express price; they structure how liquidity flows, how portfolios move, and how capital rotates. The use of stablecoins as quote assets reflects the need for a relatively stable medium in a world of high volatility.
Recent data showing record stablecoin volumes and regulatory focus highlight that these pairs are not just technicalities but play a significant role in how crypto markets operate.
