This guide explains what ETH currency is, how it works, and why it has become the second-largest cryptocurrency by market value.

You'll learn how to buy, store, and use ETH safely, along with the key factors that influence its price in today's crypto market.

Explore our comprehensive Ethereum guide.

Key Takeaways

ETH (ether) is Ethereum's native cryptocurrency, serving as both digital money and the fuel that powers network operations.
Every transaction on Ethereum requires a small gas fee paid in ETH to validators who secure the network through proof-of-stake.
ETH has become essential for DeFi applications, NFT marketplaces, and smart contracts that execute automatically without intermediaries.
The EIP-1559 upgrade burns a portion of transaction fees, making ETH potentially deflationary during periods of high network activity.
You can buy ETH on exchanges like MEXC and store it in custodial wallets (managed for you) or non-custodial wallets (you control the keys).
ETH's value fluctuates based on network usage, supply dynamics, staking demand, and broader market conditions.

What Currency is ETH and How Does It Work?

ETH, officially called "ether," is the native cryptocurrency of the Ethereum network.

When people ask "what currency is ETH," they're referring to this digital asset that exists entirely on the blockchain without any physical form.

Unlike traditional currencies controlled by central banks, ETH operates on a decentralized network maintained by thousands of computers worldwide.

The Ethereum blockchain processes ETH transactions approximately every 12 seconds, recording each transfer permanently on its public ledger.

ETH serves a dual purpose: it functions as digital money for peer-to-peer payments and as "gas" that powers every operation on the Ethereum network.

Every action on Ethereum, whether sending ETH to someone or interacting with decentralized applications, requires a small fee paid in ETH.

These fees, measured in units called "gwei" (one billionth of an ETH), go to validators who secure the network through Ethereum's proof-of-stake mechanism.

Since September 2022, Ethereum uses proof-of-stake, where validators lock up ETH as collateral to verify transactions and earn rewards, replacing the energy-intensive mining process.

Key Uses and Benefits of ETH Currency

1. Paying for Network Transactions

ETH currency powers every transaction and operation on the Ethereum blockchain through gas fees.

When you send ETH to another wallet, create an NFT, or use a decentralized application, you pay these fees to validators who process your request.

Gas prices fluctuate based on network demand, rising during busy periods and dropping when activity is lighter.

2. Storing and Growing Your Wealth

Many investors hold ETH as a store of value, similar to how people invest in gold or stocks.

You can stake your ETH to help secure the network and earn annual rewards, with validators currently earning around 6% to 8% APR based on network conditions.

Unlike keeping money in a traditional bank account, you maintain complete control over your ETH without relying on financial institutions.

3. Powering Decentralized Finance

ETH serves as the primary currency for DeFi applications that offer lending, borrowing, and trading services without intermediaries.

You can use ETH as collateral to take out crypto loans, lend your holdings to earn interest, or provide liquidity on decentralized exchanges.

The DeFi ecosystem has locked billions of dollars worth of ETH in various protocols, demonstrating its utility beyond simple payments.

4. Enabling Smart Contracts and Digital Ownership

Smart contracts built on Ethereum require ETH to execute their programmed instructions automatically when conditions are met.

These self-executing agreements power everything from NFT marketplaces to gaming platforms where you truly own your digital assets.

ETH makes it possible to transfer value and ownership instantly without lawyers, banks, or other middlemen taking a cut.

How to Buy and Store ETH Currency Safely

Getting started with ETH currency is straightforward when you use a trusted cryptocurrency exchange like MEXC.

You'll need to create an account, complete identity verification, and link a payment method such as a bank account or credit card.

MEXC allows you to buy ETH with multiple fiat currencies, making it accessible regardless of your location.

Once purchased, your ETH appears in your exchange wallet, where you can track its value in real-time and manage your holdings.

Understanding wallet security is crucial for protecting your investment: every Ethereum wallet has a public key (like an email address) that others can use to send you ETH, and a private key (like a password) that you must keep secret.

Custodial wallets on exchanges like MEXC handle your private keys for you, offering convenience and built-in security features perfect for beginners.

As you gain experience, you might explore non-custodial wallets like MetaMask, which give you complete control over your private keys and allow direct interaction with DeFi applications.

Never share your private keys or seed phrases with anyone, and be extremely cautious of phishing attempts that try to steal your credentials.

What Determines ETH Currency Value and Price?

The price of ETH currency fluctuates constantly based on supply, demand, and broader market conditions.

Understanding what drives ETH's value helps you make informed decisions about buying, selling, or holding this digital asset.

Network usage directly impacts ETH demand: when more people use Ethereum for DeFi, NFTs, or other applications, they need ETH to pay gas fees, increasing buying pressure.

Ethereum's EIP-1559 upgrade introduced a burning mechanism that permanently removes a portion of transaction fees from circulation, making ETH potentially deflationary during high network activity.

The transition to proof-of-stake reduced new ETH issuance by approximately 90%, dramatically decreasing the rate at which new supply enters the market.

Staking has locked millions of ETH, further reducing the amount available for trading and potentially supporting higher prices.

Market sentiment, regulatory developments, and global economic conditions also influence ETH's price alongside these technical factors.

Major institutional investments, like when Visa announced using Ethereum for stablecoin settlements, can drive significant price movements through increased legitimacy and adoption.
