Cryptocurrency is digital money using blockchain technology for security and decentralization. Bitcoin, created in 2009, was the first and is still the most well-known. Other popular cryptocurrencies include Ethereum, Ripple, and Litecoin.
Key features include:
• Decentralization: No central authority controls it.
• Security: Transactions are secure and transparent.
• Anonymity: Users can remain anonymous.
Cryptos offer potential for high returns but come with risks due to market volatility. They are revolutionizing finance by enabling new forms of transactions and investments.
