What are digital currencies?
Digital currencies are a form of money that exists only in electronic form. They cannot be touched or carried like paper money but are used online for purchases, investments, or transfers.
Digital currencies are divided into several types, some decentralized like Bitcoin, and some centralized managed by governments or banks.

Types of digital currencies
1. Cryptocurrencies
They are the most famous and are built on blockchain technology. They are characterized by decentralization and transparency, as they do not require an intermediary (like banks) to execute transactions.
Famous examples:
Bitcoin (BTC): The first and most famous digital currency, launched in 2009.
Ethereum (ETH): allows the creation of smart contracts and decentralized applications.
Ripple (XRP): Used for fast money transfers between banks.
2. Stablecoins
Aims to reduce price volatility associated with cryptocurrencies. Often backed by real assets such as the dollar or gold.
Examples:
USDT (Tether)
USDC (USD Coin)
3. Central Bank Digital Currencies (CBDCs)
These are digital currencies issued by central banks, considered the digital version of the national currency (like the dollar or euro).
Aims to provide a more efficient and organized payment method.
Examples:
Digital Yuan
Digital Euro – under development
4. Tokens
Used in ecosystems specific to certain applications or platforms. They can be for investment, governance, or even accessing services.
Types of tokens:
Utility Tokens: used to access services or products (e.g., BAT on the Brave browser).
Security Tokens: represent financial assets like stocks.
NFTs (Non-fungible tokens): represent digital ownership of artworks or unique content.
