+Cryptocurrency is a digital currency secured by cryptography, existing on decentralized networks using blockchain technology.
+It's not issued by any central authority, making it theoretically immune to government interference.
+Blockchain is a connected set of blocks of information on an online ledger, containing verified transactions.
+Cryptocurrencies like Ethereum's ether and Ripple's XRP serve specific purposes on their blockchains.
+The legal status of cryptocurrencies varies by country; in the US, they're considered a form of money.
+Despite risks like scams and volatility, cryptocurrencies have a market capitalization of about $1.2 trillion.
+They offer advantages such as easier fund transfers but also have disadvantages like criminal uses and volatile prices.
