Popular Cryptocurrencies:
- Bitcoin (BTC) – The pioneer cryptocurrency.
- Ethereum (ETH) – Supports smart contracts.
- Solana (SOL) – High-speed transactions.
- Ripple (XRP) – Focused on cross-border payments.

How Cryptocurrency Works
1. Decentralization
Cryptocurrencies operate on distributed networks, eliminating intermediaries like banks.
| Decentralized vs Centralized |
|--------------------------------------|----------------------------------|
| Transactions validated by nodes | Banks verify transactions |
| Enhanced security | Vulnerable to hacking |
| Lower fees | Higher fees |
Benefits:
- Transparency: Public ledger for all transactions.
- Security: Encryption prevents fraud.
2. Blockchain Technology
A tamper-proof digital ledger recording transactions across networked computers.
Key Features:
| Feature | Description |
|------------------|--------------------------------------|
| Immutability | Once recorded, data can’t be altered.|
| Consensus | Nodes agree on transaction validity.|
3. Mining & Validation
- Proof of Work (PoW): Miners solve complex puzzles (energy-intensive).
- Proof of Stake (PoS): Validators stake coins to verify transactions (eco-friendly).
4. Transactions
- Initiation: Sender signs transaction with private key.
- Verification: Network validates via consensus.
- Recording: Added to the blockchain permanently.
Tools:
- Wallets: Store public/private keys.
- Cold Wallets: Offline storage (e.g., Trezor).
Key Components
1. Cryptography
Secures transactions via encryption.
2. Smart Contracts
Self-executing code (e.g., Ethereum’s dApps).
3. Exchanges
Platforms like 👉 OKX to trade crypto.
Buying Cryptocurrency: Beginner’s Steps
- Research: Study whitepapers and market trends.
- Choose Storage: Hot (online) vs. Cold (offline) wallets.
- Mitigate Risks: Invest only what you can afford to lose.
Pros & Cons
| Pros | Cons |
|------------------------------------|----------------------------------|
