What is Cryptocurrency and how does it work?

Cryptocurrency, sometimes called cryptocurrency or crypto, is any form of currency that exists digitally or virtually and uses cryptography to secure transactions. Cryptocurrencies have no central issuing or regulating authority, instead using a decentralized system to record transactions and issue new units.

What is cryptocurrency?

Cryptocurrency is a digital payment system that does not rely on banks to verify transactions. It is a peer-to-peer system that enables anyone to send and receive payments anywhere. Instead of being carried and exchanged in the real world, cryptocurrency payments exist entirely as digital entries in online databases describing specific transactions. When you transfer cryptocurrency funds, the transactions are recorded in a public ledger. Cryptocurrency is stored in a digital wallet.

Cryptocurrency got its name because it uses encryption to authenticate transactions. This means that advanced coding is involved in storing and transferring cryptocurrency data between wallets and public ledgers. The purpose of encryption is to provide protection and security.

The first cryptocurrency was Bitcoin, which was founded in 2009 and is still the most popular today. Much of the interest in cryptocurrencies is trading for profit, with speculation sometimes driving prices sky high.

How does cryptocurrency work?

Cryptocurrencies run on a distributed public ledger called a blockchain, a record of all transactions that is updated and held by currency holders.

Cryptocurrency units are created through a process called mining, which involves using computer power to solve complex mathematical problems that generate coins. Users can also buy currencies from brokers, then store and spend them using cryptographic wallets.

If you own a cryptocurrency, you own nothing tangible. What you have is a key that allows you to transfer a record or unit of measurement from one person to another without a trusted third party.

Although Bitcoin has been around since 2009, the applications of cryptocurrencies and blockchain technology in financial terms are still emerging, and more uses are expected in the future. Transactions including bonds, stocks and other financial assets can eventually be traded using the technology.

How to store cryptocurrency

Once you buy cryptocurrency, you need to store it securely to protect it from being hacked or stolen. Typically, cryptocurrency is stored in crypto wallets, which are physical devices or online software used to securely store your cryptocurrencies’ private keys. Some exchanges provide wallet services, making it easy for you to deposit directly through the platform. However, not all exchanges or brokers automatically provide wallet services for you.

There are different wallet providers to choose from. The terms “hot wallet” and “cold wallet” are used:

Hot wallet storage: “Hot wallets” refer to crypto storage that uses online software to protect the private keys of your assets.
Cold wallet storage: Unlike hot wallets, cold wallets (also known as hardware wallets) rely on offline electronic devices to securely store your private keys.
