### What is Cryptocurrency?
Cryptocurrency is a digital or virtual currency that utilizes blockchain technology to ensure transaction security and control the generation of new units. Here’s an in-depth look at what cryptocurrency entails:
#### Definition and Basic Principles
**Digital Currency**: Cryptocurrencies exist solely in electronic form and have no physical counterparts like paper money or coins.
**Decentralization**: Most cryptocurrencies operate on decentralized systems, meaning they are not governed by central authorities like governments or banks. Instead, they use distributed ledger technology (DLT), specifically blockchain.
**Blockchain Technology**: A blockchain is a distributed ledger composed of sequential blocks, each containing a list of transactions. These blocks are linked using cryptography, creating an immutable chain.
**Cryptography**: Cryptocurrencies employ cryptographic techniques to secure transactions and prevent counterfeiting and double spending. This includes the use of public and private key encryption and hash functions.
#### Main Features of Cryptocurrency
**Anonymity and Privacy**: Many cryptocurrencies offer a degree of anonymity, making it difficult to trace the identities of transaction participants. This has raised concerns about potential misuse for illegal activities.
**Global and Borderless**: Cryptocurrencies are not confined by national borders and can be transferred globally, facilitating efficient international transactions.
**Irreversibility**: Once confirmed, cryptocurrency transactions are generally irreversible, unlike traditional bank transactions which can be reversed or refunded by financial institutions.
**Limited Supply**: Many cryptocurrencies, such as Bitcoin, have a capped supply to prevent inflation. For instance, Bitcoin is limited to 21 million coins.
#### Types of Cryptocurrencies
**Bitcoin (BTC)**: The first and most well-known cryptocurrency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It is often referred to as "digital gold."
