What is Cryptocurrency


Any kind of money that exists digitally or electronically and employs cryptography to safeguard transactions is known as cryptocurrency, sometimes referred to as crypto-currency or just crypto. Cryptocurrencies use a decentralized mechanism to track transactions and create new units rather than a central body to issue or regulate.

A digital payment system known as cryptocurrency doesn’t rely on banks to validate transactions. Peer-to-peer technology makes it possible for anybody, anywhere, to send and receive money. Payments made using cryptocurrencies do not exist as actual physical coins that may transport and exchange. Instead, they only exist as digital entries to an online database that detail individual transactions. A public ledger keeps track of all bitcoin transactions that involve money transfers. 

Due to the fact that transactions verify via encryption, cryptocurrency has earned its term. It implies that the storage, transmission, and recording of bitcoin data to public ledgers all entail sophisticated code. And the goal of this encryption is to offer security and protection.

The first cryptocurrency was created in 2009 and is still the most well-known today: Bitcoin. A large portion of cryptocurrency interest is in trading for financial gain, with speculators occasionally sending prices stratospheric. In this article, we will discuss the following:

How does Cryptocurrency Work?

A distributed public ledger known as a blockchain, updated and maintained by currency holders, is the foundation of cryptocurrencies.

A process known as mining, which employs computer power to solve challenging mathematical problems, generates units of Bitcoin. Additionally, users can purchase the currencies from brokers, then store and spend them in digital wallets.

When you hold cryptocurrencies, you don’t actually own anything. Instead, what you possess is a key that enables you to transfer a record or a measurement unit between people without using a reliable third party.

Despite the fact that Bitcoin has been available since 2009, the financial applications of cryptocurrencies and blockchain technology are constantly developing, and more in the future. 

Cryptocurrency examples

There are numerous cryptocurrencies out there in the market. And some of the most well-known are:


Ethereum, a blockchain platform created in 2015, has its own digital currency called Ether (ETH), also known as Ethereum. After Bitcoin, it is the most widely used cryptocurrency.


Despite moving more swiftly to create new ideas, such as speedier payments and processes to allow more transactions, this cryptocurrency is most comparable to bitcoin.


The original cryptocurrency, currently the most traded Bitcoin, was established in 2009. The person or group whose precise identity is still unknown, usually regarded by the pseudonym Satoshi Nakamoto, is credited with creating the money.


Ripple was created in 2012 and is a distributed ledger system. It is a tool used to track more than just bitcoin transactions. The organization that created it has collaborated with several banks and financial organizations.

The term “altcoins” distinguishes non-Bitcoin cryptocurrencies from the original.

How to Buy Cryptocurrency

You might be thinking about secure cryptocurrency purchases. Typically, there are three steps. These are:

Step 1: Choosing a Platform

The first step is to decide on a platform. In general, you have the option of using a standard broker or a specialized cryptocurrency exchange.

Traditional brokers: These are online brokers who provide services for purchasing and selling cryptocurrencies as well as other financial assets such as stocks, bonds, and ETFs. These platforms often have cheaper trading fees but fewer crypto features.

Cryptocurrency exchanges: There are several exchanges to select from, each with its own set of cryptocurrencies, wallet storage, interest-bearing account choices, and other features. In addition, several exchanges charge asset-based fees.

When comparing different platforms, consider which cryptocurrencies are available, their fees, security features, storage and withdrawal choices, and any instructional materials.

Step 2: Funding your Account

After you’ve decided on a platform, the following step is to fund your account so you can start trading. Most crypto exchanges enable users to buy crypto with fiat (government-issued) currencies like the US dollar, British pound, or Euro using their debit or credit cards; however, this varies by platform.

Credit card purchases of cryptocurrency are deemed dangerous, and some exchanges do not accept them. Crypto transactions are also not permitted by some credit card companies. Due to the extreme volatility of cryptocurrencies, it is not prudent to risk getting into debt – or perhaps paying hefty credit card transaction fees – for some assets.

Some systems support ACH and wire transactions as well. As a result, the payment methods accepted and the time required for deposits and withdrawals vary on each platform. Similarly, the time it takes for deposits to settle varies according to payment type.

However, fees are a significant consideration. These might include deposit and withdrawal transaction fees and trading costs. Fees will vary depending on payment method and platform, so do your homework ahead of time.

Step 3: Placing an Order

You can place an order using your broker’s online or mobile platform or exchange. For example, if you wish to acquire cryptocurrencies, click “buy,” then pick the order type, input the number of coins you want to buy, and complete the order. The identical procedure is also for “sell” orders.

There are alternative methods to invest in cryptocurrency. For example, payment systems such as PayPal, Cash App, and Venmo allow customers to purchase, trade, or store cryptocurrencies. There are also the following investment vehicles:

Bitcoin trusts: Bitcoin trust shares can be purchased using a traditional brokerage account. These vehicles provide regular investors with access to cryptocurrency through the stock market.

Bitcoin mutual funds: You can pick between Bitcoin mutual funds and exchange-traded funds (ETFs).

Blockchain stocks or ETFs: You may indirectly invest in crypto through blockchain businesses that are experts in the underlying technology of cryptocurrencies. You can also invest in the stocks or exchange-traded funds (ETFs) of the companies that utilize blockchain technology.

Your investing objectives and risk tolerance will determine which choice is best for you.

How to Store Cryptocurrency

Once you’ve bought cryptocurrency, you must keep it safe to avoid hackers or theft. Some exchanges provide wallet services, allowing you to store directly through the site. However, not all exchanges or brokers will immediately supply you with wallet services.

There are several wallet providers. In this regard, people often use the words “hot wallet” and “cold wallet” interchangeably:

Hot wallet storage: The term “hot wallets” refers to crypto storage that uses online software to safeguard your assets’ private keys.

Cold wallet storage: Cold wallets (also known as hardware wallets) rely on offline electrical devices to securely store your private keys instead of hot wallets.

Cold wallets often charge fees, but hot wallets do not.

What can you Buy with Cryptocurrency?

Initially introduced, Bitcoin was a medium for daily transactions, allowing users to purchase everything from a cup of coffee to a computer or even large-ticket things such as real estate. Unfortunately, that hasn’t happened yet, and while the number of institutions adopting cryptocurrencies is increasing, significant transactions involving them are uncommon. Nonetheless, crypto was used to purchase a wide range of things through e-commerce platforms. Here are a couple of such examples:

Technology and e-commerce sites:

Several tech corporations, like newegg.com, AT&T, and Microsoft, accept cryptocurrency on their websites. Overstock, an online retailer, was among the first to take Bitcoin. Shopify, Rakuten, and Home Depot also accept it.

Luxury goods:

Some high-end stores accept cryptocurrency as payment. For example, the online luxury store Bitdials accepts Bitcoin in exchange for Rolex, Patek Philippe, and other high-end timepieces.


Some vehicle dealerships, ranging from mass-market to high-end luxury, currently accept cryptocurrencies as payment.


AXA, a Swiss insurer, stated in April 2021 that it has begun taking Bitcoin as a form of payment for all of its insurance lines, excluding life insurance (due to regulatory issues). In addition, Premier Shield Insurance, which provides house and vehicle insurance coverage in the United States, accepts Bitcoin as payment for premiums. 

You can use a bitcoin debit card, such as BitPay in the United States, to spend cryptocurrency at a store that does not accept it directly.

Cryptocurrency fraud and scams

Unfortunately, bitcoin crime is becoming more prevalent. Scams involving cryptocurrency include:

Fake Websites: Fake testimonials and crypto jargon promise big, guaranteed profits if you keep investing.

Virtual Ponzi Schemes: Cryptocurrency fraudsters offer fictitious opportunities to invest in digital currencies and create the illusion of massive profits by repaying existing investors with the money of new investors. Before its offenders were arrested in December 2019, BitClub Network raised more than $700 million.

“Celebrity” Endorsements: Scammers act as millionaires or well-known figures on the internet, promising to quadruple your investment in a virtual currency but instead stealing what you contribute. They may even utilize messaging applications or chat forums to spread rumors that a well-known business person is supporting a particular cryptocurrency. Then, after encouraging investors to purchase and driving up the price, the fraudsters sell their investments, and the currency’s value falls.

Romance Scams: The FBI has issued a warning about an increase in online dating scams in which con artists persuade people they meet on dating apps or social media to invest or trade in virtual currencies. In the first seven months of 2021, the FBI’s Internet Crime Complaint Centre received over 1,800 reports of crypto-focused romantic scams, with losses totaling $133 million.

Otherwise, fraudsters may act as real virtual currency dealers or set up fraudulent exchanges in order to defraud individuals out of their money. Another type of cryptocurrency scam involves false sales presentations for cryptocurrency-based individual retirement plans. Then there’s plain cryptocurrency hacking, in which hackers get into people’s digital wallets to take their virtual cash.

Is Cryptocurrency Safe?

Blockchain technology creates cryptocurrencies. Blockchain defines how transactions are time-stamped and recorded into “blocks.” It’s a rather intricate, technical procedure, but the end result is a digital ledger of bitcoin transactions that hackers find challenging to manipulate.

Furthermore, transactions need a two-factor authentication procedure. For example, you may be requested to enter a login and password to begin a transaction. Then, you may be required to provide an authentication number delivered to your personal mobile phone through text message.

While security measures are in place, this does not mean that cryptocurrencies are impenetrable. Several high-value hacks have cost bitcoin startups a lot of money. Hackers stole $534 million from Coincheck and $195 million from BitGrail, making them two of the most potent cryptocurrency attacks of 2018.

In contrast to government-backed money, supply and demand determine virtual currencies’ value. It can result in huge fluctuations that result in significant gains or losses for investors. Furthermore, bitcoin investments have significantly less regulatory protection than traditional financial assets such as equities, bonds, and mutual funds.

Four Tips for Investing in Cryptocurrency Safely

According to Consumer Reports, all investments involve risk, but some experts believe bitcoin is one of the riskier investing options. If you want to invest in cryptocurrencies, the following suggestions might help you make informed decisions.

Research exchanges:

Learn about bitcoin exchanges before you invest. There are around 500 exchanges to select from, according to estimates. Before proceeding, conduct research, read reviews, and consult with more experienced investors.

Know how to Store your Digital Currency:

When you purchase bitcoin, you must keep it. You can save it in a digital wallet or on an exchange. While there are various types of wallets, each has its own set of advantages, technical requirements, and security. Therefore, you should investigate your storage options before investing, just as you would with exchanges.

Diversify your Investments:

Diversification is essential in any solid investment plan, and this is especially true when investing in cryptocurrencies. Don’t put all of your money into Bitcoin simply because the term is familiar to you. There are dozens of possibilities, and it is best to diversify your investments across many currencies. In addition, comply with all the financial analyses done by investment analysts and consultants. 

Prepare for Volatility:

Since the bitcoin market is very volatile, expect ups and downs. Prices will fluctuate dramatically. If your investment portfolio or mental health can’t take it, bitcoin may not be your best option.

Cryptocurrency is all the rage, but keep in mind that it is still in its infancy and very speculative. Investing in something new has risks, so be prepared. If you intend to engage, do your homework and begin by investing modestly.

A thorough antivirus is one of the greatest methods to keep online security. There are many antivirus products that can protect you from malware infections, spyware, and data theft while also safeguarding your online payments with bank-grade encryption
