What Is Cryptocurrency?
Cryptocurrencies like Bitcoin, Ethereum, or meme coins are blockchain-based digital assets. Unlike traditional points systems (e.g., Line Points), they're truly decentralized—operating without banks or governments. Examples include:
- SOL (Solana blockchain)
- ETH (Ethereum blockchain)
Uses span payments, investments, and Web3 applications (DeFi, NFTs). It's both currency and innovative protocol.
Why Create Cryptocurrencies?
Projects issue coins for:
- Fundraising: ICOs/IEOs bypass traditional finance.
- Incentives: Rewards for mining/staking/participating.
- Governance: DAO tokens enable voting.
- Ecosystem currency: Game/trading platforms use native tokens.
How Cryptocurrency Works
- Wallet: Hold assets (self-custody or exchange).
- Transaction: Sign/broadcast transfers (e.g., send BTC).
- Validation: Miners/nodes verify legitimacy.
- Recording: Immutable blockchain entry.
No banks needed—just math and consensus.
Cryptocurrency vs. Blockchain
| Aspect | Blockchain | Cryptocurrency |
|---|---|---|
| Definition | Decentralized ledger tech | Digital asset |
| Purpose | Infrastructure | Application |
| Dependency | Can exist without coins | Requires blockchain |
| Example | Ethereum, Bitcoin chain | ETH, BTC, USDT |
Blockchain enables crypto; crypto isn't mandatory for blockchains.
Bank vs. Bitcoin Transfers
| Feature | Bank Transfer | Bitcoin Transfer |
|---|---|---|
| Speed | 1-3 days (cross-border) | ~10-60 minutes |
| Fees | High (intermediaries) | Low |
| Transparency | Private | Public ledger |
| Availability | Banking hours | 24/7 |
Bitcoin eliminates intermediaries but lacks chargebacks.
Centralized vs. Decentralized Networks
| Factor | Centralized | Decentralized |
|---|---|---|
| Control | Single entity | Distributed nodes |
| Failure Risk | High (single point) | Resilient |
| Censorship | Enforceable | Resistant |
| Examples | Facebook, Banks | Bitcoin, Ethereum |
Decentralization = user sovereignty + responsibility.
