A Brief History of Cryptocurrency
From Barter to Digital Money
- Barter System: Early societies exchanged goods directly (e.g., apples for oranges), but this system faced flaws like mismatched needs and lack of divisible value.
- Modern Currency: Evolved from minted coins (110 B.C.) to paper money (1600–1900), now including digital wallets (Apple Pay, PayPal) controlled by centralized banks.
The Rise of Decentralization
Cryptocurrencies eliminate central authority, offering peer-to-peer transactions via blockchain technology.
