Cryptocurrency – Meaning and Definition

Cryptocurrency, sometimes called crypto-currency or crypto, is any currency that is digital or virtual and uses cryptography to secure transactions. Cryptocurrencies have no central issuer or regulatory authority, instead using a decentralized system to record transactions and issue new units.

What is cryptocurrency?

Cryptocurrency is a digital payment method that does not rely on banks to verify transactions. It is a peer-to-peer system where anyone anywhere can send and receive money. Unlike physical money in the real world, cryptocurrency payments exist only as digital entries in online databases detailing specific transactions.

When you transfer cryptocurrency funds, the transaction is recorded on a public ledger. Cryptocurrencies are stored in digital wallets.


The cryptocurrency got its name because it uses encryption to verify transactions. This means that storing and transferring cryptocurrency data between wallets and public ledgers involves extensive coding. The purpose of encryption is to provide security and protection.

Bitcoin was the first cryptocurrency established in 2009 and is still very popular today. Interest in cryptocurrencies is traded for massive profits, with speculators sometimes sending prices skyrocketing.

How does cryptocurrency work?

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

Cryptocurrency units are created through a process called mining, which uses computing power to solve complex mathematical problems to generate coins. Users can buy, store and spend coins from brokers using cryptographic wallets.

If you own cryptocurrency, you obviously own nothing. You have the key that allows you to move records or units of measurement from one person to another without a trusted third party.

Although Bitcoin has only existed since 2009, the applications of cryptocurrency and blockchain technology are still growing economically, and more applications are expected in the future. Transactions including bonds, stocks and other financial assets could eventually be traded using the technology.

Examples of Cryptocurrencies
There are thousands of cryptocurrencies. Some of these are known:


Founded in 2009, Bitcoin was the first cryptocurrency and is still commonly traded. This coin was minted by Satoshi Nakamoto – widely believed to be the pseudonym of a person or persons whose exact identity is unknown.


Created in 2015, Ethereum is a blockchain platform that has its own cryptocurrency called Ether (ETH) or Ethereum. It is the most popular cryptocurrency after Bitcoin.



The currency is very similar to Bitcoin, but has moved toward rapid innovation, including processes that allow faster payments and more transactions.


Ripple is a distributed ledger system founded in 2012. Waves can be used to track many types of transactions, not just cryptocurrencies. The company behind this has worked with various banks and financial institutions.

Non-Bitcoin cryptocurrencies are collectively called “altcoins” to distinguish them from the original.

how to buy cryptocurrency
You may be wondering how to buy cryptocurrencies safely. It usually consists of three stages. These are:

Step 1: Choosing a Site

The first step is to decide which platform to use. In general, you can choose a traditional broker or a dedicated cryptocurrency exchange:

Traditional brokers. Online brokers that offer ways to buy and sell cryptocurrencies, stocks, bonds, and ETFs. These platforms offer low trading costs but fewer crypto features.

Cryptocurrency Exchange. There are many cryptocurrency exchanges to choose from, each offering different cryptocurrencies, wallet storage, interest-bearing account options, and more. Most exchanges charge asset-based fees.

Comparing different platforms, which cryptocurrencies are offered, what they charge, their security features, storage and withdrawal options

Step 2: Fund your account

Once you’ve chosen your platform, the next step is to fund your account and you can start trading. Most crypto exchanges allow users to use their debit or credit cards to buy crypto using fiat (i.e. government-issued) currencies such as US dollars, British pounds or euros – but this varies by platform.

Crypto purchases using credit cards are considered risky and some exchanges do not support them. Some credit card companies don’t even allow crypto transactions. This is because cryptocurrencies are very volatile and it may not be worth taking out a loan for some assets or paying high credit card transaction fees.

Some sites accept ACH transfers and wire transfers. Accepted payment methods and timing of deposits or withdrawals vary from platform to platform. Similarly, the time to repay the deposit varies depending on the payment method.

An important factor to consider is the fee. This includes potential investment, withdrawal transaction fees and trading fees. Fees vary by payment method and site and should be researched initially.


Step 3: Ordering

You can place orders through your broker or exchange’s web or mobile site. If you wish to purchase cryptocurrency, you may do so by selecting “Buy”, selecting an order type, entering the amount of cryptocurrency you wish to purchase, and confirming the order. The same process applies to “sell” orders.

There are other ways to invest in crypto. These include payment services such as PayPal, CashApp and Venmo that allow users to buy, sell or hold cryptocurrencies. In addition, the following investment instruments are available:

Bitcoin Trust:

You can buy Bitcoin Trust shares using a regular brokerage account. These vehicles provide retail investors with crypto exposure through the stock market.

Bitcoin Mutual Funds: There are Bitcoin ETFs and Bitcoin Mutual Funds to choose from.
Blockchain Stocks or ETFs: You can invest in crypto indirectly through blockchain companies that specialize in crypto and the technology behind crypto transactions. Alternatively, you can buy stocks or ETFs of companies that use blockchain technology.

How to save cryptocurrency

After you buy cryptocurrency, you need to keep it safe to protect it from being hacked or stolen. Typically, cryptocurrencies are stored in crypto wallets, which are physical devices or online software used to securely store your cryptocurrencies’ private keys.

Some exchanges offer wallet services that make it easy to store funds directly through the site. However, not all exchanges and brokers will automatically provide you with wallet services.

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

Hot Wallet Storage: “Hot wallet” refers 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.

What can be bought with cryptocurrency?

When it first launched, Bitcoin was envisioned as a medium for everyday transactions, making it possible to buy everything from a cup of coffee to big-ticket items like computers or real estate.

This is not fully realized, and although the number of companies accepting cryptocurrencies is increasing, large transactions involving it are rare. However, a wide variety of products can be purchased from e-commerce websites using crypto. These are some examples:

Technology and E-Commerce Platforms:

Many companies that sell tech products accept crypto on their websites, such as newegg.com, AT&T, and Microsoft. E-commerce platform Overstock was one of the first to accept Bitcoin. It has been adopted by Shopify, Rakuten and Home Depot.

Luxury goods:

Some luxury retailers accept crypto as payment. For example, online luxury retailer Bitdeals offers Rolex, Patek Philippe and other high-end watches in exchange for Bitcoin.
