What is cryptocurrency and how does it work?

Cryptocurrency – definition and meaning

Cryptocurrency, also known as crypto or crypto-currency, is any digital or virtual currency that employs encryption to safeguard transactions. Instead of a central issuing or regulating authority, a decentralized system records transactions and issues new units for cryptocurrencies.

What is digital currency?

Cryptocurrency is a digital payment mechanism independent of banks for transaction verification. It is a peer-to-peer system that allows anyone, regardless of location, to make and receive payments. Cryptocurrency payments exist solely as digital entries in an online database that describe individual transactions. When bitcoin funds are transferred, the transactions are recorded in a public ledger. Digital wallets are used to store cryptocurrency.

Cryptocurrency derives its name from the use of encryption to authenticate transactions. This means that storing and sending cryptocurrency data between wallets and public ledgers requires complex coding. Encryption is intended to ensure security and safety.

Bitcoin, which was created in 2009 and remains the most popular cryptocurrency today, was the first digital currency. Speculators sometimes drive cryptocurrency values through the stratosphere as they attempt to benefit from trading.

How do cryptocurrencies operate?

All cryptocurrency transactions are recorded on a distributed public ledger called blockchain, which is held by currency holders.

The technique through which units of cryptocurrency are generated is known as mining, and it entails the use of computer power to solve complex mathematical puzzles that generate coins. Users can also purchase the currencies via brokers, store them in encrypted wallets, and spend them.

If you own cryptocurrencies, you do not possess anything physical. What you possess is a key that enables you to transfer a record or unit of measure from one person to another without a third-party intermediary.

Although Bitcoin has been since 2009, cryptocurrencies and financial applications of blockchain technology are still in their infancy, and additional usage is anticipated shortly. Eventually, transactions involving bonds, stocks, and other financial assets could be executed via this technology.

Examples of Cryptocurrency

There are thousands of digital assets. Among the most well-known are:


Bitcoin, which was created in 2009, was the first cryptocurrency and remains the most widely traded. The currency was created by Satoshi Nakamoto, who is commonly thought to be a pseudonym for an unknown individual or group of individuals.


Ethereum is a blockchain platform with its cryptocurrency, Ether (ETH) or Ethereum, which was developed in 2015. After Bitcoin, it is the most popular cryptocurrency.


This money is most comparable to bitcoin, although it has developed innovations more rapidly, including speedier payments and procedures that enable more transactions.



In 2012, Ripple, a distributed ledger technology, was founded. Ripple may be used to monitor more than just financial transactions. Its creators have collaborated with numerous banks and financial institutions.

Alternative cryptocurrencies to Bitcoin are collectively referred to as “altcoins” to differentiate them from Bitcoin.

How to acquire virtual currency

You may be wondering how to safely acquire cryptocurrency. Typically, there are three processes involved. These include:

Step 1: Platform selection

Choosing the platform to utilize is the initial step. You can typically select between a standard broker and a specialized cryptocurrency exchange.

  • Conventional brokers These are online brokers that facilitate the purchase and sale of cryptocurrency in addition to equities, bonds, and ETFs.
  • Typically, these platforms offer reduced trading fees but fewer crypto features.

There are cryptocurrency exchanges. There are numerous cryptocurrency exchanges from which to choose, each of which offers a variety of cryptocurrencies, wallet storage, and interest-bearing account alternatives, among others. Numerous exchanges levy asset-based fees.

Consider which cryptocurrencies are available, the platform’s costs, security features, storage and withdrawal choices, and any educational materials when comparing platforms.

Account funding is the second step

After selecting a platform, the following step is to fund your account to begin trading. The majority of crypto exchanges permit users to acquire cryptocurrencies with fiats (i.e. government-issued) currencies such as the US Dollar, the British Pound, or the Euro using debit or credit cards, however, this varies by platform.

Credit card purchases of cryptocurrencies are deemed hazardous, and some exchanges do not support them. Some credit card providers prohibit cryptocurrency transactions as well. Due to the extreme volatility of cryptocurrencies, it is not wise to risk incurring debt or paying excessive credit card transaction fees for specific assets.

Additionally, some systems accept ACH transactions and wire transfers. The approved deposit and withdrawal methods and processing times vary by platform. Similarly, the time required for deposits to clear varies depending on the payment type used.

Fees are an important element to consider. These include potential transaction costs for deposits and withdrawals, as well as trading fees. Fees will vary by payment method and platform, therefore it is important to conduct preliminary research.

Third stage: placing an order

You can place an order via the web or mobile platform of your broker or exchange. You can purchase cryptocurrencies by selecting “buy,” selecting the order type, entering the number of coins you wish to acquire, and confirming the order. The same procedure applies to orders to “sell.”

There are additional ways to invest in cryptocurrencies. These include payment platforms such as PayPal, Cash App, and Venmo that enable users to purchase, sell, or store cryptocurrencies. In addition, the following investment vehicles are available:

Bitcoin trusts: Bitcoin trust shares can be purchased using a standard brokerage account. These instruments provide ordinary investors access to cryptocurrencies via the stock market.

There are Bitcoin ETFs and Bitcoin mutual funds available for investment.

You can also indirectly invest in cryptocurrencies through blockchain companies that specialize in the technology underlying cryptocurrencies and cryptocurrency transactions. Alternatively, you may invest in the stocks or ETFs of companies that employ blockchain technology.

The optimal choice for you will depend on your investment objectives and risk tolerance.

How to store digital currencies

Once you have acquired bitcoin, you must store it securely to prevent hacking or theft. Cryptocurrency is typically held in crypto wallets, which are physical hardware or internet software used to securely store your cryptocurrency’s private keys. Some exchanges offer wallet services, making it simple to store digital assets directly on the platform. However, not all exchanges and brokers provide wallet services automatically.

There are various wallet providers from which to pick. Use of the words “hot wallet” and “cold wallet”

Hot wallet storage: “hot wallets” refer to crypto storage that employs internet software to safeguard your secret keys.

Cold wallet storage: Unlike hot wallets, cold wallets (also known as hardware wallets) save your private keys using offline technological equipment.

Cold wallets typically charge fees, whereas hot wallets do not.

What may be purchased with cryptocurrencies?

Bitcoin was initially meant to be a medium for daily transactions, allowing for the purchase of anything from a cup of coffee to a computer or even expensive things such as real estate. This has not yet occurred, and while the number of institutions that accept cryptocurrencies is expanding, significant transactions involving cryptocurrencies are uncommon. Nevertheless, it is feasible to purchase a vast array of goods through e-commerce websites using cryptocurrencies. Here are several examples:

Technology and online commerce:

Several websites that offer technology products accept cryptocurrency, including newegg.com, AT&T, and Microsoft. Overstock was one of the first e-commerce platforms to accept Bitcoin. Additionally, Shopify, Rakuten, and Home Depot accept it.

Luxury goods:

Some high-end retailers accept cryptocurrency as payment. Bitdials, an online luxury merchant, accepts Bitcoin in exchange for Rolex, Patek Philippe, and other high-end watches.



Some vehicle retailers, ranging from mass-market to luxury brands, already accept cryptocurrencies as payment.


AXA, a Swiss insurer, stated in April 2021 that it has begun taking Bitcoin as payment for all of its insurance lines besides life insurance (due to regulatory issues). Premier Shield Insurance, an American provider of house and car insurance, also accepts Bitcoin for premium payments.

If you wish to spend cryptocurrency at a merchant that does not take it directly, you can utilize a cryptocurrency debit card, such as BitPay in the United States.


Fraud and cons with cryptocurrencies

Unfortunately, cryptocurrency-related crimes are increasing. Among crypto-currency frauds are:

Fake websites: Fake websites that incorporate fabricated testimonials and crypto jargon and promise large, guaranteed returns if you continue to invest.

Virtual Ponzi schemes: Cryptocurrency thieves offer nonexistent possibilities to invest in digital currencies and create the illusion of astronomical returns by paying off existing investors with the funds of new investors. Before its offenders were indicted in December 2019, one fraud scheme, BitClub Network, amassed more than $700 million.

“Celebrity” endorsements: online scammers act as billionaires or well-known figures, promising to multiply your investment in a virtual currency but instead stealing what you contribute. They may even utilize messaging applications or chat forums to spread the rumor that a prominent businessperson supports a particular cryptocurrency. After encouraging investors to purchase and driving up the price, con artists liquidate their holdings, causing the currency’s value to decrease.

The FBI has issued a warning about a surge in online dating scams, in which con artists convince individuals they meet on dating apps or social media to invest or trade in virtual currencies. In the first seven months of 2021, the Internet Crime Complaint Centre of the FBI received more than 1,800 reports of crypto-focused romance scams, with losses approaching $133 million.

Otherwise, fraudsters may act as legitimate virtual currency traders or establish phony exchanges to defraud individuals into handing over their money. Another crypto scam involves false sales presentations for cryptocurrency-based individual retirement plans. Then there is conventional cryptocurrency hacking, in which hackers get access to digital wallets where users store their virtual currency to steal it.

Are cryptocurrencies secure?

Typically, cryptocurrencies are created utilizing blockchain technology. Blockchain explains the method by which transactions are grouped into “blocks” and time-stamped. It’s a rather sophisticated and technical procedure, but the result is an unalterable digital log of cryptocurrency transactions.

Moreover, transactions necessitate a two-factor authentication procedure. To initiate a transaction, you may be required to enter a login and password. Then, you may be required to provide an authentication number sent to your cell phone through text message.

Despite the presence of security measures, cryptocurrencies are not hack-proof. Several high-dollar breaches have incurred significant costs for bitcoin startups. Coincheck was hacked for $534 million and BitGrail was hacked for $195 million, making them the two largest cryptocurrency attacks of 2018.

Contrary to government-backed currency, the value of virtual currencies is solely determined by supply and demand. This can result in violent fluctuations that cause substantial gains or losses for investors. Moreover, cryptocurrency investments are subject to significantly less regulatory protection than conventional financial assets such as equities, bonds, and mutual funds.

Four methods for investing securely with cryptocurrencies

According to Consumer Reports, all investments involve risk, but bitcoin is one of the riskier investing options available. If you wish to invest in cryptocurrencies, following guidelines will help you make informed decisions.

Academic exchanges:

Before investing, familiarise yourself with bitcoin exchanges. There are reportedly around 500 exchanges to choose from. Before proceeding, conduct research, read reviews, and consult with more seasoned investors.

Learn how to securely keep your digital currency:

When you get cryptocurrency, you must keep it. You can store your cryptocurrency on an exchange or in a digital wallet. Each type of wallet has its advantages, technical requirements, and security measures. As with exchanges, before investing you should study your storage options.

Diversify your holdings:

Diversification is essential to any successful investment strategy, and investing in bitcoin is no exception. Don’t throw all your money into Bitcoin, for example, simply because you recognize the word. There are dozens of alternatives, and it is preferable to invest in multiple currencies

Prepare for uncertainty:

Be prepared for ups and downs in the cryptocurrency market, which is highly volatile. There will be severe price fluctuations. If your investment portfolio or mental health cannot manage such volatility, cryptocurrencies may not be the best option for you.

Remember that cryptocurrency is still in its relative infancy and is regarded as highly speculative, despite its current popularity. Be prepared for difficulties while investing in anything novel. If you choose to engage, conduct a study and invest cautiously at first.

Utilizing a thorough antivirus is one of the greatest ways to maintain online safety. Kaspersky Internet Security protects you against malware infections, spyware, and data theft, and safeguards your online transactions with bank-level encryption.
