Cryptocurrency is a digital or virtual form of currency that relies on cryptography for security.
Bitcoin, created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto, was the first cryptocurrency.
The total supply of most cryptocurrencies is capped, providing a fixed maximum number of coins that can ever be mined or created.
Blockchain technology is the underlying decentralized ledger that records all transactions in a transparent and secure manner.
Altcoins refer to any cryptocurrency other than Bitcoin, and there are thousands of them with various features and purposes.
Initial Coin Offerings (ICOs) are a fundraising method where new cryptocurrencies sell their underlying tokens to the public.
Smart contracts are self-executing contracts with the terms of the agreement directly written into code, running on blockchain platforms like Ethereum.
Cryptocurrencies can be stored in digital wallets, which can be hardware-based (physical devices) or software-based (applications).
The process of validating transactions and adding them to the blockchain is called mining, typically done by specialized computers.
Cryptocurrencies offer pseudonymity, as transactions are recorded on the blockchain, but user identities are not necessarily tied to wallet addresses.
Volatility is a common characteristic of cryptocurrency prices, leading to significant fluctuations in value over short periods.
Fiat-to-crypto exchanges allow users to buy cryptocurrencies with traditional currencies like USD, EUR, or GBP.
Decentralized Finance (DeFi) refers to financial services and applications built on blockchain, aiming to replace traditional financial intermediaries.
Some countries embrace cryptocurrencies, while others impose strict regulations or outright bans on their use.
Cryptocurrency wallets use private keys for access, and losing these keys can result in irreversible loss of funds.
The concept of "hard fork" in cryptocurrencies involves a radical change to the protocol, often leading to a split and the creation of a new cryptocurrency.
Cryptocurrencies can be used for various purposes, including online purchases, remittances, and as a store of value.
Stablecoins are a type of cryptocurrency designed to minimize price volatility by pegging their value to a stable asset, often a fiat currency.
Regulatory challenges, security concerns, and scalability issues are some of the ongoing challenges in the cryptocurrency space.
The environmental impact of cryptocurrency mining, particularly for Proof-of-Work (PoW) coins like Bitcoin, has raised sustainability concerns.
