What is Stablecoin

Sep 3, 2025

A stablecoin is a cryptocurrency whose value is pegged to something stable, most commonly the U.S. dollar. For example, one unit of a popular stablecoin like USDC or USDT is always meant to be worth about $1. These coins achieve stability by being backed by reserves (like dollars in a bank account or short-term U.S. government bonds) and by maintaining that peg through transparent issuance and redemption mechanisms.


Stablecoins: The Digital Dollars That Don’t Fluctuate

When most people hear “cryptocurrency,” they think of Bitcoin or Ethereum — and their unpredictable price swings. But there’s a different kind of digital currency designed to stay steady: stablecoins. In fact, some countries have even taken steps toward officially recognizing or adopting them as government-backed currencies, such as through legislation like the Genuin Act in the United States.

A stablecoin is a cryptocurrency whose value is pegged to something stable, most commonly the U.S. dollar. For example, one unit of a popular stablecoin like USDC or USDT is always meant to be worth about $1. These coins achieve stability by being backed by reserves (like dollars in a bank account or short-term U.S. government bonds) and by maintaining that peg through transparent issuance and redemption mechanisms.

You can think of stablecoins as digital cash that moves as easily as email — no physical bills, no bank middlemen, and no limits on geography.


A Real-World Scenario: Paying Across Borders When Banks Fail

Imagine you run a small design agency in Mexico City. You have freelancers in Argentina, Brazil, and Colombia. Every month, you need to send them their payments.

Here’s the problem:

  • Bank transfers across Latin America are often slow — sometimes taking days.
  • They’re expensive — fees can eat up 5–10% of the payment.
  • Currency exchange rates fluctuate and local currencies can lose value quickly.
  • In some countries, strict capital controls make it hard to move money in or out at all.

Now, picture this: instead of wiring money through multiple banks, you send stablecoins. You convert $1,000 into USDC and transfer it directly to your freelancer’s crypto wallet. Within seconds, they receive exactly $1,000 worth of USDC. They can keep it as digital dollars or exchange it locally for their own currency when needed.


Why Stablecoins Beat Traditional Bank Transfers in This Case

  1. Speed Bank transfers can take 3–5 business days across borders. Stablecoin transactions often settle in under in seconds — even on weekends and holidays.
  2. Lower Cost International wire fees can run from $20–$50 per transaction, plus hidden currency conversion charges. Stablecoin transfers can cost as little as a few cents or even less than 1 cent.
  3. Global Access Stablecoins don’t require you to have a local bank account. All you need is a Mizu account and internet connection. You will be able to receive and send US dollars without having a bank account.
  4. Stability in Volatile Economies Holding funds in a stablecoin pegged to the U.S. dollar helps protect against local currency inflation. In economies where prices can jump week-to-week, stablecoin provides a safe store of value.

They’re not the “future” of money in some far-off sense. In places like Latin America, stablecoins are already solving real problems today. If you're interested in using Stablecoin in your business or day-to-day transactions, feel free to leave a message here.
