It is commonly used in the financial industry to amplify the potential returns from an investment. However, while leverage can magnify profits, it can also magnify losses. Key Points: • Mechanism: Leverage is achieved by borrowing funds to increase the size of a trade or... More blockchainA blockchain is a decentralized and distributed digital ledger used to record transactions across multiple computers in a way that ensures the data can only be modified once it has been recorded. Once a block of data is recorded on the blockchain, it becomes extremely difficult to change it without altering all subsequent blocks, which requires consensus from the majority... More technology to gain decentralizationDecentralization refers to the process of distributing and dispersing power, functions, and decision-making authority from a central entity or location to multiple entities or locations. Instead of having a single central authority that makes decisions and holds power, decentralization spreads out these responsibilities among several players or nodes. Key Features of Decentralization: • Distributed Authority: No single entity has complete... More, transparency, and immutability.

Key Features:

1. Decentralization: Cryptocurrencies operate on a decentralized network of computers, meaning no central authority governs or regulates it.
2. Cryptography: Secure transactions and control the creation of new units.
3. Transparency: All transactions are recorded on a public ledgerA ledger is a record-keeping system that maintains a complete and verifiable history of transactions. In the context of cryptocurrencies and blockchain technology, a ledger is a digital record of all transactions that have ever taken place on a particular blockchain network. Key Points: • Types of Ledgers: • Physical Ledger: Traditional record-keeping systems where transactions are recorded manually. •... More called the blockchain.

The platform uses "gas" as a unit to measure the computational effort required to execute operations. More: Known for its smart contractA smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. It is a protocol intended to digitally facilitate, verify, or enforce the negotiation or performance of a contract, without the need for intermediaries. Key Points: • Decentralization: • Smart contracts are stored on blockchain platforms, ensuring... More functionality.
3. Ripple (XRP): Known for its digital payment protocol more than its cryptocurrency.
4. Litecoin (LTC): Created as the “silver” to Bitcoin’s “gold”.
5. Cardano, Polkadot, Binance Coin: Examples of other notable cryptocurrencies.
