$ETH Sure! Here's a simple breakdown:

- **ETH** stands for **Ethereum**, which is one of the biggest and most important cryptocurrencies, after Bitcoin.

- A **coin pair** means **two currencies that are traded against each other** on a crypto exchange. So when you see **ETH paired with something else**, like **ETH/USDT** or **ETH/BTC**, it shows you're trading **Ethereum** for another currency.

For example:

- **ETH/USDT** means you're trading Ethereum against **Tether** (a stablecoin pegged to the US dollar).

- **ETH/BTC** means you're trading Ethereum against **Bitcoin**.

In these trades:

- The **first** coin (ETH) is the one you're buying or selling.

- The **second** coin (like USDT or BTC) is the one you're pricing it in.
