Study Notes
Cryptocurrencies
Definition: Cryptocurrencies are digital or virtual currencies that use cryptography for security and are decentralized, meaning they are not controlled by any government or financial institution.
Key Features:
- Decentralized: Transactions are recorded on a public ledger called a blockchain, which is maintained by a network of computers rather than a central authority.
- Digital: Cryptocurrencies exist only in digital form.
- Limited supply: Most cryptocurrencies have a limited supply of coins or tokens, which helps to prevent inflation.
- Fast and global: Transactions are fast and can be sent and received anywhere in the world in real-time.
Types of Cryptocurrencies:
- Bitcoin (BTC): The first and most well-known cryptocurrency, created in 2009.
- Altcoins: Alternative cryptocurrencies that are not Bitcoin, such as Ethereum (ETH), Litecoin (LTC), and Monero (XMR).
- Tokens: Cryptocurrencies that are issued on top of another blockchain, such as Ethereum-based tokens like ERC-20.
- Stablecoins: Cryptocurrencies that are pegged to the value of a fiat currency, such as USD Coin (USDC) and Tether (USDT).
How Cryptocurrencies Work:
- Mining: The process of verifying transactions and adding them to the blockchain, which is rewarded with a certain amount of cryptocurrency.
- Wallets: Software or hardware that stores cryptocurrency and allows users to send and receive it.
- Transactions: The process of sending and receiving cryptocurrency, which is recorded on the blockchain.
Advantages:
- Security: Cryptocurrencies are secure due to the use of advanced cryptography and the decentralized nature of the blockchain.
- Anonymity: Transactions are pseudonymous, meaning that users can make transactions without revealing their real identities.
- Fast and low-cost: Transactions are fast and often have lower fees compared to traditional payment systems.
Disadvantages:
- Volatility: The value of cryptocurrencies can fluctuate rapidly and unpredictably.
- Regulatory uncertainty: The regulatory environment for cryptocurrencies is still unclear and evolving.
- Security risks: Cryptocurrencies are vulnerable to hacking and other security risks.
