🔄 What do centralization and decentralization mean in currencies?
🔒 Centralized currencies
They are controlled by a single entity, like the government or a central bank.
Such as: digital dollar or digital riyal (if issued).
This entity can issue the currency, halt its circulation, or track it.
Advantage: Legal regulation and protection from fraud.
Disadvantage: Loss of privacy and excessive control.
🌀 Decentralized currencies
They are not controlled by a single entity.
They rely on a technology called blockchain.
Such as: Bitcoin, Ethereum.
Transactions are verified through a network of computers (miners).
Advantage: Freedom, privacy, resistance to censorship.
Disadvantage: Legal protection is minimal, and price fluctuations are high.
