$ETH

Ethereum (often misspelled as "Etherum") is a decentralized, open-source blockchain platform that enables smart contracts and decentralized applications (dApps). Here are some key aspects:

### **1. What is Ethereum?**

- A blockchain network designed for programmable transactions (smart contracts).

- Second-largest cryptocurrency by market cap after Bitcoin.

- Native cryptocurrency: **Ether (ETH)**.

### **2. Key Features**

- **Smart Contracts**: Self-executing code that runs when conditions are met.

- **Decentralized Apps (dApps)**: Applications running on Ethereum (e.g., DeFi, NFTs, gaming).

- **Ethereum Virtual Machine (EVM)**: Executes smart contracts across nodes.

- **Proof-of-Stake (PoS)**: Since "The Merge" (2022), Ethereum uses PoS for energy efficiency.

### **3. Use Cases**

- **DeFi (Decentralized Finance)**: Lending, trading (e.g., Uniswap, Aave).

- **NFTs (Non-Fungible Tokens)**: Digital ownership (e.g., CryptoPunks, Bored Apes).

- **Web3**: Decentralized internet infrastructure.

### **4. ETH vs. Bitcoin (BTC)**

- Bitcoin: Digital gold (store of value).

- Ethereum: Programmable blockchain (smart contracts, dApps).

### **5. Upgrades (Ethereum 2.0)**

- **Scalability**: Layer 2 solutions (e.g., Arbitrum, Optimism) and sharding (future update).

- **Lower Fees**: EIP-1559 introduced fee burning, making gas fees more predictable.

### **6. Challenges**

- **Gas Fees**: High during network congestion.

- **Scalability**: Still a work in progress (sharding expected in future updates).

### **7. How to Buy & Store ETH**

- **Buy**: Exchanges like Coinbase, Binance, Kraken.

- **Store**: Wallets like MetaMask, Ledger, Trezor.

### **8. Future Outlook**

- Ethereum aims to become more scalable, secure, and sustainable with ongoing upgrades.
