What Are Stablecoins? USDT, USDC and the Digital Dollar Explained
In a world where cryptocurrencies can swing up or down 10% in a single day, there's one category that stays steady: stablecoins. They're the favorite entry point for millions of people across Latin America who want to save in dollars digitally, without the headaches of volatility.
In this guide we explain what they are, how USDT and USDC work, and why X4T —an official partner of Circle, the issuer of USDC— is the ideal place to trade them.
What is a stablecoin?
A stablecoin is a cryptocurrency designed to hold a fixed value, usually pegged to the US dollar at a 1:1 ratio. In other words, 1 stablecoin = 1 dollar.
Unlike Bitcoin or Ethereum, whose prices fluctuate constantly, stablecoins are not meant to be a speculative investment. Instead, they serve as a way to:
- Save in dollars without holding a foreign bank account
- Protect yourself from inflation in local currencies
- Send and receive money quickly and cheaply
- Trade in crypto without exposure to volatility
How do they keep their value stable?
Most of the more trustworthy stablecoins are backed by real reserves. For every stablecoin in circulation, the issuer holds the equivalent in dollars or liquid assets (such as US Treasury bonds) in audited accounts.
This means you can always redeem your stablecoin for its dollar value, which keeps its price anchored.
USDT vs USDC: the two most important stablecoins
There are many stablecoins, but two dominate the market: USDT (Tether) and USDC (USD Coin).
USDT (Tether)
- It's the most widely used stablecoin in the world and the one with the highest trading volume
- Available on multiple networks (Tron, Ethereum, Solana, etc.)
- Very popular in Latin America for saving and transfers
- Ideal for its liquidity and universal acceptance
USDC (USD Coin)
- Issued by Circle, a regulated US company
- Known for its transparency: reserves audited monthly
- 100% backed by cash and US Treasury bonds
- The preferred choice for institutions and users who prioritize regulatory compliance
Which one should you choose?
Both are excellent. USDT offers greater liquidity and acceptance; USDC offers greater transparency and regulatory backing. On X4T you can trade both, according to your preference.
