​What is Cryptocurrency?

​Cryptocurrency (or "crypto") is a type of digital or virtual currency. Its defining feature is that it uses cryptography for security, making it extremely difficult to counterfeit.

​Key Features:

​Decentralized: Unlike traditional currencies (like the Taka or Dollar), most cryptocurrencies are not issued or controlled by any central bank or government. This is a core distinction.

​Blockchain Technology: Crypto operates using a decentralized ledger system called blockchain. This is a distributed database shared among a network of computers that records transactions securely and transparently.

​Popular Forms of Crypto:

​Bitcoin ($BTC ): The first and most widely recognized cryptocurrency, often considered "digital gold."

​Ethereum ($ETH ): The second-largest crypto by market value. Its blockchain is designed to support smart contracts and decentralized applications (dApps).

​A Note on Context: This information is helpful for understanding the absolute fundamentals.
