Cryptocurrency is a type of digital currency that uses cryptography to secure and verify transactions, without the need for a central authority like a bank or government. Cryptocurrencies are based on a technology called blockchain, which is a distributed ledger that records all transactions in a network of computers. Cryptocurrencies can be used to buy goods and services, or traded for profit, on online platforms that support them. Some of the most popular cryptocurrencies are Bitcoin, Ethereum, and Dogecoin
Types of Cryptocurrency
There are many types of cryptocurrencies, but they can be broadly classified into two categories: coins and tokens.
Coins
Coins are cryptocurrencies that run on their own blockchain, which is a network of computers that validate and store transactions. Coins have their own native currency, such as Bitcoin (BTC), Ethereum (ETH), or Litecoin (LTC). Coins can be used as a medium of exchange, a store of value, or a unit of account. Coins can also be mined, which is a process of generating new coins by solving complex mathematical problems using computing power
Tokens
Tokens are digital assets that are created on existing blockchains, such as Ethereum or Binance Smart Chain. Tokens can represent various things, such as utility, value, or security. Tokens can be used to access services, platforms, or applications that are built on the blockchain. Tokens can also be traded, bought, or sold on cryptocurrency exchanges or marketplaces. Some examples of tokens are Tether (USDT), Binance Coin (BNB), or CryptoKitties (CK)
