Ethereum is one of the most popular blockchain platforms, and its native cryptocurrency, Ether (ETH), ranks second only to Bitcoin in market capitalization. As of October 2022, approximately 122 million Ether tokens were in circulation. But what exactly are Ethereum and Ether? How does ETH 2.0 change the landscape? Below, we break down everything you need to know.
What Is Ethereum?
Ethereum is the first and largest decentralized application platform built on blockchain technology. Proposed in 2013 by Vitalik Buterin, it launched in July 2015 with the goal of improving upon Bitcoin’s limitations. Unlike Bitcoin, Ethereum is not just a digital currency but a multifunctional platform supporting smart contracts, decentralized apps (DApps), and more.
Key Features:
- Decentralized: No central authority controls Ethereum.
- Smart Contract Capability: Self-executing contracts with terms written in code.
- DApp Support: Enables developers to build applications without intermediaries.
What Is Ether (ETH)?
Ether (ETH) is the native cryptocurrency of the Ethereum blockchain. It serves as the "fuel" for transactions, smart contract executions, and DApp operations. Think of Ether as the currency used within the Ethereum "country," similar to how the USD operates in the U.S.
Ether Basics:
- Symbol: Ξ
- Supply: No cap, but annual issuance is fixed (~18 million ETH).
- Use Cases: Payments, staking, DeFi collateral, and more.
Ethereum vs. Ether: Key Differences
| Ethereum | Ether (ETH) |
|---|---|
| Blockchain platform | Native cryptocurrency |
| Supports smart contracts | Used to pay gas fees |
| Cannot be traded | Tradable on exchanges |
How Ethereum Works
Ethereum operates via the Ethereum Virtual Machine (EVM), which executes smart contracts across a decentralized network. Here’s the process:
- A user initiates a transaction or smart contract.
- Nodes (miners/validators) process the request via EVM.
- Valid transactions update the blockchain.
- Users pay gas fees in ETH for computations.
Ethereum 2.0: The Upgrade to Proof-of-Stake (PoS)
Ethereum’s transition to ETH 2.0 replaces energy-intensive mining (PoW) with staking (PoS), improving scalability and reducing energy use by ~99.95%.
Phases of ETH 2.0:
- Phase 0: Beacon Chain launch (PoS activation).
- Phase 1: The Merge (PoW to PoS transition).
- Phase 2: Shard Chains (64 chains for faster transactions).
Ether vs. Bitcoin: A Side-by-Side Comparison
| Metric | Ether (ETH) | Bitcoin (BTC) |
|---|---|---|
| Consensus | PoS (post-merge) | PoW |
| Supply | Uncapped | Capped at 21 million |
| Use Case | Smart contracts, DeFi | Digital gold |
| Transaction Speed | ~5 minutes | ~10 minutes |
How to Buy and Invest in Ether
Steps to Buy ETH:
- Choose an Exchange: e.g., Coinbase, Binance.
- Deposit Funds: Transfer fiat (e.g., USD/TWD) or crypto.
- Place Order: Buy ETH at market or limit prices.
Storage Options:
- Hot Wallets: Convenient but online (e.g., MetaMask).
- Cold Wallets: Offline, more secure (e.g., Ledger).

Risks of Investing in Ether
- Inflation: No supply cap could impact long-term value.
- Competition: Rivals like Solana offer lower fees.
- Volatility: Prices often correlated with Bitcoin.
- Security Risks: Smart contract vulnerabilities exist.
FAQs About Ether
Q: Should I invest in Ether or Bitcoin?
A: Diversify! BTC is a store of value; ETH supports DeFi and apps.
Q: How can I stake ETH?
A: Use staking pools or exchanges like Kraken post-merge.
Final Thoughts
Ethereum’s versatility makes it a cornerstone of Web3, DeFi, and NFTs. While promising, always invest responsibly and never risk more than you can afford to lose.
