What is Ethereum?
Ethereum is a decentralized digital asset network and the second-largest cryptocurrency by market capitalization after Bitcoin. As of March 2026, Ethereum's market cap sits at approximately $233 billion, compared to Bitcoin's $1.33 trillion.
The network's native cryptocurrency is called Ether (ETH). Approximately 121 million ETH are currently in circulation, and unlike Bitcoin, Ethereum has no fixed supply cap.
When was Ethereum created?
Ethereum was originally conceptualized in late 2013 when Vitalik Buterin published a white paper proposing a general-purpose blockchain that could run decentralized applications, addressing limitations in Bitcoin's restricted scripting language. The founding team raised 31,000 BTC (approximately $18 million at the time) through a public crowdfunding campaign in mid-2014. Ethereum's mainnet launched on July 30, 2015, when the genesis block was mined into existence under the codename "Frontier".
What is Ethereum 2.0?
Ethereum 2.0 is an ongoing series of network upgrades designed to improve Ethereum's scalability, security, and energy efficiency. The centrepiece of Ethereum 2.0 was the Merge, executed on September 15, 2022, which transitioned the blockchain from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) model.
Under PoW, miners competed to solve complex mathematical problems using large amounts of computing power to validate transactions.
Under PoS, validators stake ETH as collateral for the right to validate transactions and earn rewards, removing the need for energy-intensive mining.
The Merge reduced Ethereum's energy consumption by approximately 99.95%.
How does Ethereum work?
Ethereum works by using a blockchain-based network where thousands of computers (called nodes) run software that validates transactions and maintains a shared ledger. The platform adopts the blockchain technology established by Bitcoin but extends it with programmable smart contracts, which are self-executing programs that run automatically when predefined conditions are met.
Every interaction on Ethereum follows 3 steps:
A user initiates a transaction, which involves sending ETH, transferring tokens, or calling a smart contract function.
Validators (nodes that have staked ETH as collateral) verify the transaction against the network's rules and confirm it is legitimate.
The validated transaction is recorded permanently on the blockchain, updating the shared ledger across all nodes simultaneously.
Ethereum vs Ether: what is the difference?
The difference between Ethereum and Ether is that Ethereum is a blockchain network, while Ether (ETH) is the native cryptocurrency used to pay for transactions on that network. Ethereum provides the infrastructure, and Ether is the asset used to pay for operations on that infrastructure.
In practice, “Ethereum” and “Ether” are often used interchangeably.
When a trader says "I bought Ethereum," they almost always mean they purchased Ether.
When a developer says "I built on Ethereum," they mean they deployed a smart contract on the Ethereum network.
The difference matters because Ethereum as a network also hosts thousands of other tokens (USDT, LINK, UNI) that are not Ether but still depend on it, since every transaction and smart contract execution on the network requires Ether to pay gas fees.
What moves the price of Ethereum?
The price of Ethereum is driven by 6 primary factors:
Bitcoin price movements
Macroeconomic conditions
Network activity and gas fees
Protocol upgrades
Investor sentiment and speculation
Competition from alternative blockchains
1. Bitcoin price movements
Moves in Bitcoin's price are the primary driver of Ether's price. Over a two-year period measured by CME Group, Bitcoin's daily price movements explained 75% of the daily price movements in ETH, with Ether showing a beta of 1.105 relative to Bitcoin. When Bitcoin rallies or sells off, Ether tends to follow in the same direction with slightly amplified moves.
2. Macroeconomic conditions
Interest rate expectations, large capital inflows into risk assets, and overall investor risk tolerance directly affect demand for ETH. When central banks signal lower rates or economic stability, capital tends to flow into speculative assets including cryptocurrencies. When conditions tighten, that capital withdraws.
3. Network activity and gas fees
Higher usage of the Ethereum network (more transactions, more smart contract calls) increases demand for ETH, since every operation requires gas fees paid in Ether. Periods of heavy DeFi and NFT activity have historically coincided with rising ETH prices, while declining on-chain activity reduces buying pressure.
4. Protocol upgrades
Major upgrades including the Merge (2022), Shapella (2023), Dencun (2024), and Pectra (2025) have reshaped Ethereum's technical and economic design, and successful upgrades strengthen long-term confidence. Each upgrade affects transaction costs, staking rewards, and network capacity, all of which feed into how the market values ETH.
5. Investor sentiment and speculation
Ether is in demand as both a utility token and an investment asset. Short-term price movements are frequently driven by trader sentiment, social media momentum, whale activity (large holders buying or selling), and the launch of investment products such as spot Ethereum ETFs, which opened institutional access in 2024.
6. Competition from alternative blockchains
Ethereum competes with alternative smart contract platforms for developers, capital, and user activity, and shifts in narrative or performance can redirect liquidity away from Ether and toward competing tokens such as Solana (SOL) or Avalanche (AVAX).
What is Ethereum used for?
Ethereum is used to build and run decentralized applications across finance, gaming, digital identity, and supply chain management. Five primary use cases define the network today:
Decentralized finance (DeFi)
Non-fungible tokens (NFTs)
Payments and value transfer
Decentralized applications (dApps)
Investment and staking
1. Decentralized finance (DeFi)
Ethereum hosts lending, borrowing, and trading protocols that replicate traditional banking services without intermediaries. Users can earn interest on deposits, take out collateralised loans, and swap tokens through decentralized exchanges such as Uniswap and Aave, all executed by smart contracts rather than banks.
2. Non-fungible tokens (NFTs)
Ethereum is the primary blockchain for creating, buying, and selling NFTs, which are unique digital tokens that represent ownership of items such as artwork, collectibles, event tickets, and virtual real estate. Ethereum's ERC-721 token standard established the framework that most NFT marketplaces still use.
3. Payments and value transfer
Ether functions as a digital currency for peer-to-peer payments. Users can send ETH to any address globally without relying on a bank or payment processor. Stablecoins issued on Ethereum (USDT, USDC) extend this further by offering dollar-denominated transfers on the same network.
4. Decentralized applications (dApps)
Developers deploy smart contracts on Ethereum to build applications across gaming, identity management, supply chain tracking, and governance systems (DAOs). These applications run on the blockchain rather than on centralised servers, giving users direct control over their data and assets.
5. Investment and staking
Ethereum has become a popular investment vehicle and store of wealth. Beyond buying and holding ETH as a speculative asset, holders can stake their Ether to help secure the network and earn annual staking rewards, or gain exposure through regulated investment products such as spot Ethereum ETFs.
6. Trading
Ether is one of the most actively traded cryptocurrencies in the world, available on both spot exchanges and as a CFD instrument through regulated brokers. Traders speculate on ETH price movements against fiat currencies (ETH/USD) and other cryptocurrencies (ETH/BTC), using tools such as leverage, technical analysis, and automated strategies across platforms that operate around the clock.
Ether (ETH) is the common thread across all five use cases. Every transaction, smart contract execution, and token transfer on the network requires ETH to pay gas fees, making it the essential operating currency of the Ethereum ecosystem.
How do I trade Ethereum?
You can trade Ethereum through 2 venues: a cryptocurrency exchange or a crypto CFD broker.
Cryptocurrency exchanges let you buy and sell actual Ether at its current market price through what is known as spot trading. You deposit fiat currency or another cryptocurrency, purchase ETH, and hold it in a digital wallet. Spot trading means you profit only when the price rises above your purchase price. Exchanges also offer features such as staking and access to thousands of other tokens, but you are responsible for securing your own assets.
Crypto CFD brokers offer Ethereum as a contract for difference (CFD), a derivative that tracks Ether's price without requiring you to own the underlying asset. CFD trading allows you to go long (profit from rising prices) or go short (profit from falling prices), and to use leverage to increase market exposure with a smaller deposit. You do not need a crypto wallet, but leveraged positions carry higher risk and overnight financing charges apply.
An exchange is the direct route to own Ether, use it on the Ethereum network, or stake it for rewards. A CFD broker is the more suitable option to speculate on short-term ETH price movements in both directions with leverage.

How do I invest in Ethereum?
You can invest in Ethereum through 3 methods:
1. Direct purchase. Buy Ether (ETH) on a cryptocurrency exchange, transfer it to a digital wallet, and hold it as a long-term asset. Most exchanges allow fractional purchases, so you do not need to buy a full token. Direct ownership gives you full control of your ETH and the ability to use it on the Ethereum network, participate in DeFi protocols, or stake it to earn rewards.
2. Staking. Lock your ETH to help validate transactions on the Ethereum network and earn annual rewards, which currently range from approximately 3% to 5%. Staking can be done directly (requiring a minimum of 32 ETH to run a validator node) or through a staking pool or exchange service that accepts smaller amounts. Liquid staking protocols issue a receipt token (such as stETH) that represents your staked position, allowing you to retain liquidity while earning yield.
3. Exchange-traded funds (ETFs). Spot Ethereum ETFs, offered by firms such as BlackRock and Fidelity, provide price exposure to Ether through a standard brokerage account. ETFs remove the need to manage wallets or private keys, and some staking-enabled versions distribute a portion of staking rewards to shareholders. The trade-off is management fees and no direct access to the Ethereum network.
The right method depends on your experience and objectives. Direct purchase suits investors who want full ownership and network access. Staking suits holders looking to generate passive yield. ETFs suit investors who prefer a familiar brokerage structure without managing digital assets directly.
