What Is an On-Ramp?

Euros, dollars, and pounds sit in bank accounts. Stablecoins live on a blockchain. An on-ramp is what connects the two.

Think of it as the entry point into crypto. You put in fiat, you get out a digital asset pegged to that same currency. Start from zero, wallet empty, trading knowledge optional.

USDC holds its value at one dollar. Bitcoin and Ethereum move with the market. Stablecoins sit still. That consistency makes them the natural starting point for anyone buying crypto for the first time.

How to Get Your First Stablecoin

With your account set up, your first stablecoin is a few steps away.

On the home screen, tap More in the main menu to see all available options.
The services menu opens. Under the Trade section, hit Quick Buy.
The purchase screen has two fields: what you're sending and what you'll get back. USDC is already selected as the destination. Choose your payment method and enter an amount to get started.
Type in the amount you want to convert. The platform shows how much USDC you'll receive and at what rate. Press Continue.
Look over the numbers. Hit Confirm when you're good.
The purchase registers with a Pending Payment status. The screen shows the total, the rate applied, and the estimated amount arriving in your account.

Ready to Start?

Getting your first stablecoin used to mean bouncing between platforms and second-guessing every step. This partnership cuts that out. Create your CoinEx account, follow the steps in this guide, and let the Mercuryo widget handle the conversion. The whole thing happens inside one app.

Understanding Stablecoins: How Businesses Use USDT and USDC

Your finance team sent a $50,000 payment to a supplier in Vietnam on Monday. It’s Thursday, the money still hasn’t arrived, and no one can tell you which intermediary bank is holding it up. That kind of problem is why companies are moving to stablecoins. USDT and USDC now account for over 80% of a market that passed $305 billion in 2025, roughly the size of Finland’s entire gross domestic product, and businesses are using them to settle cross-border payments in minutes instead of days. Two regulatory frameworks gave them the confidence to make that switch: the U.S. GENIUS Act and the EU’s MiCA, both requiring issuers to hold equal reserves and operate under licensed oversight. For companies evaluating stablecoins as payment infrastructure, the rules are finally in place.

Buy Crypto with a US Bank Account: ACH Transfer Explained

If your platform only offers card payments, you are leaving money on the table. Credit cards carry 2 to 3% processing fees, frequent declines on crypto purchases, and chargeback risk that eats into margins. Bank transfers eliminate all three.

ACH offers zero-fee deposits for recurring purchases, while wire transfers give same-day settlement for high-value transactions. What follows is the infrastructure breakdown: how ACH and wire work, when to offer each, and how to extend the same experience to users outside the US.
