What Is Ethereum? The World Computer, Explained
Ethereum explained simply: smart contracts, ETH vs BTC, staking, gas fees, layer 2 networks, and what gives ether its value.

Bitcoin is digital money. Ethereum is something different: a global, shared computer that anyone can build on — and ETH is the fuel it runs on.
The core idea: smart contracts
Ethereum launched in 2015, created by Vitalik Buterin and co-founders. Its innovation is the smart contract — a program that lives on the blockchain and executes exactly as written, without a company operating it.
That single idea spawned entire industries:
- DeFi — lending, borrowing and trading without banks or brokers
- Stablecoins — most USDT and USDC in existence moves over Ethereum and its networks
- NFTs — verifiable ownership of digital items
- DAOs — internet-native organisations governed by token holders
When people say “crypto is programmable money,” Ethereum is what they mean.
ETH vs BTC: different assets, different bets
| Bitcoin | Ethereum | |
|---|---|---|
| Purpose | Store of value | Platform for applications |
| Supply | Hard cap: 21M | No hard cap; low, sometimes negative net issuance |
| New coins | Mining (proof of work) | Staking (proof of stake) |
| Analogy | Digital gold | Digital oil / an index on onchain activity |
Buying BTC is a bet on scarce, neutral money. Buying ETH is a bet that economic activity keeps moving onchain — and that Ethereum stays the platform it happens on.
Staking, gas and layer 2s in one minute
- Gas: every transaction pays a fee in ETH. Busy network = higher gas. This is ETH’s built-in demand.
- Staking: since 2022, Ethereum is secured by validators who lock up ETH and earn yield (roughly 2–4% APR). Exchanges like Bitget offer staking products that handle the technical side.
- Layer 2s (Arbitrum, Optimism, Base and others): networks built on top of Ethereum that make transactions dramatically cheaper while inheriting its security. Most user activity now happens there.
The honest risk list
- ETH has historically fallen as hard as, or harder than, BTC in bear markets.
- Competing chains (notably Solana) take real market share in users and activity.
- The “ultrasound money” supply story depends on network usage staying high.
How to buy ETH on Bitget
- Create your account and complete verification.
- Deposit USDT or fiat — the deposit guide walks through it.
- Trade ETH/USDT on spot. If you plan to hold, look at Bitget’s ETH staking products under Earn to put the position to work.
