Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control.
The most well-known cryptocurrency is Bitcoin, but there are many others including Ethereum, Litecoin, and Ripple. Cryptocurrencies work using a technology called blockchain. Blockchain is a distributed database that keeps a public record of all cryptocurrency transactions. This record is known as a blockchain ledger. The ledger is distributed across a network of computers, and each transaction must be verified by the computers in the network before it can be added to the blockchain..
How to buy cryptocurrency
Cryptocurrencies are often bought and sold on exchanges. There are a number of exchanges that allow you to buy and sell cryptocurrencies. Some exchanges only allow crypto-to-crypto transactions, while others also allow you to buy crypto with fiat currency (such as USD). When buying crypto on an exchange, you will need to create an account and provide some personal information. You will also need to set up a crypto wallet to store your coins. There are two types of wallets: hot wallets and cold wallets. Hot wallets are connected to the internet and are therefore more vulnerable to hacking. Cold wallets are offline and are considered to be more secure.
Advantages and disadvantages to using cryptocurrencies

For example, because they are not subject to government or financial institution control, it can be difficult to get your money back if you are scammed. Additionally, the value of cryptocurrencies can be very volatile, meaning that the value of your coins could go up or down significantly in a short period of time.
