I’ve been reviewing how stablecoins actually work—how they’re quite different from what many people believe. They’re not just regular cryptocurrencies, but something much closer to traditional money in digital form.

The thing is that stablecoins are assets designed to maintain a fixed value, typically pegged to the US dollar. While Bitcoin and Ethereum go up and down wildly, these coins stay stable around $1. That’s why they function as a safe haven within the crypto market.

In the current market, there are different types. The most common are backed directly by dollars held in bank accounts: USDT and USDC are the clearest examples. Then there are those collateralized with cryptocurrencies, like DAI, which uses Ethereum as collateral. There are also ones backed by physical gold, like PAXG, as well as algorithmic stablecoins that keep their price through smart code.

Looking at the figures right now, USDT is still leading with a market cap of 189.86 billion, followed by USDC with 76.75 billion. But what’s interesting is that we’re seeing more and more options: USDE with 4.45 billion, DAI with 4.35 billion, USD1 with 2.15 billion, FDUSD with 1.45 billion, and PayPal’s PYUSD with 3.51 billion. The ecosystem is diversifying quite a lot.

For those seeking regulatory security, USDC is the most established option. For anyone who prefers total decentralization, DAI is the bet within the DeFi ecosystem. USDE is interesting because, in addition to being stable, it also generates yield if you deposit it into its protocol. FDUSD works well when you need fast liquidity—especially in Asia—and USD0 stands out for its multichain flexibility.

What truly makes stablecoins valuable is their practical utility. You can send money to another country for cents in fees, in seconds. You don’t need a bank. They operate 24/7 without time restrictions. And anyone with internet access can use them, even if they don’t have a bank account.

In countries with high inflation, like Argentina or Venezuela, people use them as a safe haven because they preserve their value while local currencies fall apart. For international remittances, they’re revolutionary. In DeFi, they’re the foundation of everything: loans, staking, decentralized exchanges—everything runs on stablecoins.

Honestly, although they won’t make you rich quickly, stablecoins—at their core—are a fundamental tool in any balanced crypto portfolio. In a market as volatile as this, having assets that preserve value isn’t a luxury; it’s almost a necessity. And considering how regulators in EE.UU. and Europe are legitimizing them, we’ll probably see even more institutional adoption going forward.
