Cryptocurrencies are digital or virtual assets that use cryptography to secure transactions, control the creation of additional coins, and verify asset transfers without the need for a centralized entity. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control.
Cryptocurrencies are often compared to traditional banking systems where transactions are verified by a third party, such as a central bank or credit card company.
However, cryptocurrencies differ in that they use decentralized technologies to verify transactions as opposed to centralized entities.
For example, sending money from one bank to the other requires the use of a third party, such as an intermediary bank, to complete and verify the transaction.
With cryptocurrency transactions, however, there is no need for an intermediary as the transaction is verified by the decentralized network of computers on the blockchain.
This makes cryptocurrency transactions much faster and more efficient than traditional banking methods.
What is Blockchain?
A blockchain can be described as a digital ledger that keeps track of all cryptocurrency transactions. With each transaction, the blockchain grows continually as it stores and secures each transaction into immutable blocks of transactions.
Each block contains information such as the sender, receiver, and amount involved in the transaction. Once a block is completed it is added to the blockchain, creating an immutable record of all past transactions.
The blockchain is constantly growing as new blocks are added to it with each new transaction. Validators or miners on the specified blockchain network confirm the transaction by verifying the digital signature before it is added to the blockchain. These validators are also decentralized therefore making it impossible for them to be censored by any government or collaborate to commit fraud on the network.
How Do People Use Cryptocurrency?
Cryptocurrency is often used as a speculative investment, similar to how people invest in stocks or gold. Cryptocurrency investors hope that the value of their coins will go up so they can sell them at a profit.
Others use cryptocurrency to buy goods and services. Bitcoin, for example, is often used to buy online goods and services.
Some people also use cryptocurrency as a way to send or receive money internationally. Because cryptocurrency transactions are not subject to exchange rates or transaction fees, they can be a cheaper way to send money internationally than traditional methods like wire transfers.

How Do I Buy Cryptocurrency?
Cryptocurrency can be purchased on exchanges or directly from other people through various marketplaces.
You can go to a cryptocurrency exchange which is an online platform where you can buy, sell, or trade cryptocurrencies for other digital currencies or traditional fiat currencies like US dollars or Euros.
To use an exchange, you will need to create an account and verify your identity. Once you have set up an account, you can deposit money into your account and use it to buy cryptocurrency.
Cryptocurrency exchanges are mostly unregulated, and the security of your account depends on the security measures put in place by the exchange.
It is important to research an exchange before you decide to create an account as some exchanges have been hacked in the past, resulting in the loss of customer funds.
