A cryptocurrency is a digital or virtual asset designed to work as a medium of exchange. It uses cryptography to secure its transactions and to control the creation of new units of the currency. Cryptocurrencies are decentralized; they are not subject to government or financial institution control.
Bitcoin, created in 2009, was the first decentralized cryptocurrency. Since then, numerous other cryptocurrencies have been created. These are frequently called altcoins, as a contraction of “bitcoin alternative.
For example, Ethereum, launched in 2015, is considered by many to be the second-most successful cryptocurrency after Bitcoin.
What is Blockchain?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings.
Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the blockchain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
What is Mining?
Mining is how new Bitcoin and other cryptocurrencies are created. Miners are rewarded with cryptocurrency for verifying and committing transactions to the blockchain.
Ethereum miners are rewarded based on their share of work done, rather than their share of the total number of blocks mined.
Cryptocurrency exchanges are online platforms where you can buy, sell, or exchange cryptocurrencies for other digital or fiat currencies. Bitcoin and Ethereum are two of the most popular cryptocurrencies, but there are many other types as well.

What is a Wallet?
A cryptocurrency wallet is a digital wallet used to store, send, and receive digital currency like Bitcoin. Some wallets also allow you to hold traditional fiat currencies. Cryptocurrency wallets come in many forms, but the most important thing is that they are secure.
Cryptocurrency is still a new and evolving technology. As such, it is important to do your own research before investing in any cryptocurrency. This guide should not be taken as investment advice.
What is NFT?
A non-fungible token (NFT) is a type of cryptocurrency that represents a unique asset, such as a digital file, an image, or a piece of virtual land. NFTs are stored on a blockchain, like Bitcoin or Ethereum, and can be bought, sold, or traded like other cryptocurrencies.
Unlike fungible tokens, which are interchangeable and have the same value, each NFT is unique and cannot be replaced by another. This makes them valuable to collectors and investors who see them as digital works of art or rare collectibles.
NFTs have been used to represent everything from in-game items to digital real estate. Some platforms, such as Decentraland and Cryptovoxels, allow users to buy, sell, or trade virtual land on a blockchain. Other platforms, such as Axie Infinity, use NFTs to represent in-game items that can be used, traded, or sold.
