What is Cryptocurrency?

Cryptocurrency has shaken up the financial world, offering a decentralized alternative to traditional money. Whether you’re eyeing it as a long-term investment, a hedge against inflation, or just a way to diversify your portfolio, crypto is no longer just a niche interest—it’s a major asset class. But what exactly is cryptocurrency, and how does it work? In this article, we’ll break down the essentials, from blockchain technology to key use cases, so you can better understand what you’re investing in.

Introduction

Like any other currency, cryptocurrencies can be used to buy and sell goods and services. The big difference? They’re entirely digital and secured by cryptography, making transactions safe and decentralized. While crypto does have practical uses, most of the buzz comes from traders looking to profit off price swings. With no central authority regulating them, even though global regulators are trying to do so, cryptocurrencies can see wild price movements driven by market speculation—sometimes sending their value soaring, as we’ll explore later.

What Is a Cryptocurrency?

Cryptocurrency is a type of digital or virtual currency that uses cryptography for security, making them nearly impossible to counterfeit or double-spend—a key advantage in the digital world. Unlike traditional currencies, digital assets face a unique challenge known as double-spending, where the same token could be used more than once. This risk exists because digital information can be copied, and while most people wouldn’t know how to exploit it, those with the right technical skills and a deep understanding of blockchain networks could, in theory, attempt to game the system.

This is where blockchain technology comes in. Most cryptocurrencies operate on a decentralized blockchain—a distributed ledger maintained by a network of independent computers. Unlike fiat currencies, which central banks control, cryptocurrencies generally aren’t issued or regulated by any single authority. This decentralization makes them resistant, by design, to government intervention or manipulation, reinforcing their appeal to those looking for financial independence outside traditional banking systems.

What Is Blockchain Technology and How is it Related to Cryptocurrencies?

To really get cryptocurrencies, you first need to understand the backbone of every crypto transaction: blockchain. At its core, blockchain is a type of distributed ledger technology (DLT), a broad term for systems that enable secure, decentralized exchanges of value. Think of it as a database, but instead of being controlled by a single entity, it’s spread across a network of users. Transactions are recorded in “blocks,” which are then linked together to form a “chain.” Each block gets a unique identifier, called a hash, which acts like a digital fingerprint, ensuring that data can’t be altered or tampered with.

So why does blockchain matter? It’s more secure, efficient, and faster than traditional financial systems—but the real game-changer is decentralization. Traditional finance relies on intermediaries like banks, central banks, and governments to control currency and transactions. Blockchain flips that model on its head by distributing power and trust across a network of users. It eliminates the need for middlemen, giving individuals more control over their assets while maintaining security and transparency. In this article, we’ll focus on one of the most well-known uses of blockchain: cryptocurrencies.

History of Cryptocurrencies

During the mid-to-late-1990s’ tech boom, there were several attempts to create a digital currency, and systems like Flooz, Beenz and DigiCash quickly emerged on the market, but eventually failed miserably. There were many different reasons for their failures, including fraud and financial problems, to name a few. Notably, all of those systems utilized a Trusted Third-Party approach, signifying that the companies behind them verified and facilitated the transactions. Due to the failures of these companies, the creation of a digital cash system was seen as a “lost cause” for quite a long time.

Come 2009, when an anonymous group of programmers under the alias “Satoshi Nakamoto” introduced the first digital currency, Bitcoin. Described by its launchers as a “peer-to-peer electronic cash system,” it is completely decentralized, meaning there are no servers involved, and no central controlling authority. The concept closely resembles P2P networks for file sharing of music, or otherwise.

Of course, and as noted earlier, one of the most important problems that any electronic payment network has to address is that of double-spending. More simply, this is a fraudulent technique of spending the same amount twice. The conventional solution to counter this phenomenon was a trusted third party – a central server – that kept records of the balances and transactions. However, this method always entailed an authority in control of your funds and with all your sensitive personal details on hand.

In a decentralized network like Bitcoin, every participant needs to do this chore. This is done by way of the Blockchain – a public ledger of all transactions that ever happened within the network, available to everyone. Therefore, everyone in the network can see every account’s balance.

Every transaction is a file that consists of the sender’s and recipient’s public keys (wallet addresses) and the number of coins transferred. The transaction also needs to be signed off by the sender with their private key. All of this is just basic cryptography. Eventually, the transaction is broadcasted in the network, but it needs to be validated first.

Within a cryptocurrency network, only “miners'' can confirm transactions by solving a cryptographic puzzle: first by taking transactions, second by marking them as legitimate and third by spreading them across the network. Afterward, every node of the network adds it to its database. Once the transaction is confirmed, it becomes unforgeable and irreversible, and a miner receives a reward, plus the transaction fee.

Fundamentally, any cryptocurrency network is based on the absolute consensus of all the participants regarding the legitimacy of balances and transactions. If nodes of the network oppose a single balance, the system would basically collapse. However, there are many rules pre-programmed into the network that prevent this from happening.

Understanding Cryptocurrencies

Types of Cryptocurrency

As aforementioned, the first blockchain-based cryptocurrency was Bitcoin, which continues as the world’s most popular and most valuable. However, today there are thousands of other cryptocurrencies, with various functions and specifications. Some of these are simply clones of Bitcoin, while others are new currencies that were built from zero. As of February 2025, there are approximately 19.82 million Bitcoins in circulation, with a total market capitalization of around $1.935 trillion.

Some of the competing cryptocurrencies established because of Bitcoin’s success, known as “altcoins,” include Litecoin, Peercoin and Namecoin, as well as Ethereum, Cardano and EOS. As of early 2025, the total market capitalization of all cryptocurrencies is approximately $3.18 trillion, with Bitcoin accounting for about 60% of that value.

Most Common Cryptocurrencies

Cryptocurrencies have not only changed the world’s expectations surrounding money and financial assets, but they have also continued to evolve in their own space since the first Bitcoin block was mined in 2009. Since then, thousands of unique cryptocurrencies have burst forth. Of these, Bitcoin remains the most popular. As of October 2022, approximately 17% of U.S. adults have invested in, traded, or used cryptocurrency, a figure that had remained stable since 2021. Among these cryptocurrency users, a significant portion have invested in Bitcoin, though exact percentages vary across studies. For instance, a 2024 report found that up to 40% of American adults own crypto, up from prior findings.

1. Bitcoin (BTC)

It has been well over a decade since Bitcoin launched its currency into the digital space. Since that time, it has remained the most popular cryptocurrency in the world. With Bitcoin, users can transfer money from one digital wallet to another with relative ease. Each transaction is then verified by other users and recorded on the public ledger, known as the blockchain. Some key factors that have contributed to Bitcoin’s eye-popping popularity include:

• High Value. Although it fluctuates widely, its price has always remained lofty. A single Bitcoin is worth $104,000 as of this writing. This is significantly higher than other cryptocurrencies that exist.

• Major companies are starting to accept Bitcoins. These include Microsoft and Overstock.com, among others.

• Bitcoin is easy to set up and is supported by the most preeminent exchanges and digital wallet platforms around the globe, such as Coinbase. This makes the process of getting into the “game” easier.

• Investors have been supporting Bitcoin’s growth for years. Bitcoin has been around longer than all other cryptocurrencies, which has allowed it to gain a strong following of investors and enthusiasts.

• Bitcoin has the highest market capitalization among cryptocurrencies, which is often considered carefully by investors before they make a decision. Market caps are calculated by multiplying the current supply of the currency by the current market price. This is known as the “circulating supply of currency,” and can indicate whether or not a currency is a risky investment. High market caps usually indicate less risk because there are more users. Therefore, Bitcoin is believed to be a better choice than other cryptocurrencies out there.

2. Ethereum (ETH)

Bitcoin flurry aside, another widely admired cryptocurrency is Ethereum. This cryptocurrency uses a blockchain that is similar to Bitcoin’s, but has a totally different currency. Ethereum’s currency is called Ether. Like Bitcoin, it is managed by an open network of users.

The predominant area from where Ethereum branches off from Bitcoin is with its “smart contracts.” These are digital contracts that pay users only after certain conditions are met. Benefits of smart contracts generally include:

• Eliminating third parties in transactions. For example, if you have a smart contract for your house. In a traditional transaction, you would need a realtor to help you with paperwork and mediate the transaction with the buyer. With smart contracts, however, you can transfer ownership of the home to the buyer without anyone else’s involvement. You also do not have to pay third parties, as you would with a realtor.

• Quick transactions. You do not have to wait for paperwork to process. Smart contracts are faster and easier, as everything is done over the Internet. Indeed, you avoid great amounts of paperwork altogether.

• Transactions are verified by hundreds of other users. In addition to your transactions being verified, they are also encrypted and stored on a public ledger. This helps keep a documented record of your transaction, ultimately helping secure it.

3. Ripple (XRP)

Though most cryptocurrencies boast about providing rapid transactions, for Ripple – and its digital tokens known as XRP – lightning-fast transactions are a particular piece of its uniqueness. In fact, Ripple processes transactions in as few as four seconds. You can compare this to Ethereum, which takes two minutes, and Bitcoin, which is a bit longer. By sharp contrast, traditional currencies can take a few days.

Ripple works by creating a platform for banks and other payment providers to send money around the planet. XRP can be exchanged in any currency. For instance, it can be used for exchanges in dollars, euros or the Japanese Yen. Being able to send money around the globe in seconds allows banks and financial institutions to reach new frontiers more quickly. The farther their reach goes, the more customers they can serve. Other notable features of Ripple’s XRP tokens that contribute to their popularity include:

• Being a cost-effective option for sending money. You can send money across borders in seconds, relatively cheaply, without having to pay high foreign exchange fees and other costs.

• Having notable institutional investors backing it. For example, both Accenture and Google Ventures have invested an equity stake in Ripple.

• Enjoying high scalability. This refers to faster transaction speeds, which are required for cryptocurrencies to compete globally. According to industry sources, Ripple can handle 1,500 transactions per second.

4. Litecoin (LTC)

Litecoin and Bitcoin have more in common than just the “coin” in their names: Litecoin has a blockchain, public ledger and miners, all at once, for the verification of transactions. However, there are three key features that make Litecoin stand out even more:

• Processing speed. Litecoin processes transactions more quickly than does Bitcoin. In fact, Litecoin processes transactions in about 2.5 minutes while Bitcoin processing can take up to 10 minutes.

• Larger supply of currency. Litecoin has 84 million Litecoins in total, compared to Bitcoin’s 21 million.

• Less complex algorithms. Compared to Bitcoin, Litecoin has algorithms that are easier to undo. This can make mining transactions simpler to solve, and miners also will not need as much high-tech equipment to solve them as they would with Bitcoin.

5. Bitcoin Cash (BCH)

Although Bitcoin is the most popular cryptocurrency at present, that does not mean it is without flaws. In fact, its youngest family member, Bitcoin Cash, was created to help improve Bitcoin's scalability, which, among other things, affects transaction speed and has led to a gain in popularity for Bitcoin Cash.

To help improve transaction speed, Bitcoin Cash increased each block size from one megabyte (MB) to eight MBs. Each block represents a list of transactions that need to be verified. Increasing the block size allows more transactions to be verified each time. In turn, increasing the number of transactions that can be processed should also help Bitcoin Cash compete with bigger, more established companies, such as PayPal, Visa and Mastercard. Further, Bitcoin Cash also aims to cut transaction fees.

With all the available cryptocurrencies, how do you know which, if any, to choose? In a nutshell, the most useful way to determine if a cryptocurrency is popular is to look at its market capitalization, which shows you the circulating supply of the currency worldwide. From there, you can investigate what features make sense for your future transactions. For instance, would smart contracts be useful to you? If so, you may want to use Ethereum. For super-fast processing, you might choose Ripple. Regardless of what you are seeking, cryptocurrencies are not likely to disappear anytime soon. Rather, they may just be the currency of the future.

How to Trade Cryptocurrencies? CFDs vs. Cryptocurrencies Trading Exchange

In more ways than one, cryptocurrency trading can be compared to foreign exchange trading: the markets in various fiat currencies from all over the world are traded against each other. In FOREX trading, US dollars can be used to purchase a position or an option in euros, Swiss Francs or any other currency, and then sold again at the time of the investor’s choosing, booking either a profit or a loss on the trade.

Cryptocurrency trading is very similar to FOREX, allowing traders to purchase cryptocurrency with US dollars. As with FOREX, cryptocurrency traders can trade with a buy-and-hold strategy or trade the daily or weekly up-and-down volatility. There are several tools available by which you can potentially make a profit from a cryptocurrency, even when it is going down in value. These include futures contracts and binary options.

Due to considerable volatility in Bitcoin and altcoin trading, as well as the frequent use of leverage in these types of trades, betting on a downward move in price, called “shorting,” is not generally recommended for less-experienced traders.

With Bitcoin itself trading for thousands of dollars, it might seem like the cost is price-prohibitive for most traders to take a position, but Bitcoin and other cryptocurrencies may be purchased as a decimal-based fraction of a coin. While Bitcoin is limited to 21 million coins, about 18 million of which are already in circulation, the ability to trade partial Bitcoin allows for each of those 21 million coins to be split 100 million times – in theory at least. In practice, however, not all crypto exchanges support such small units in trades. Most exchanges have you to specify an amount you want to purchase in US dollars. The exchange then calculates how much Bitcoin or other altcoins you can buy with that amount of money.

Other ways to gain exposure to cryptocurrency

Traders drawn to invest in cryptocurrencies may also do so by channeling money into specialized funds that purchase Bitcoin or altcoins. Though these funds can often carry a significant premium when compared to direct trading, they simplify the process of cryptocurrency ownership, as well as provide a way to gain exposure to cryptocurrencies in more conventional investment accounts, like individual retirement accounts (IRA) and personal accounts. Not only that, crypto exchange traded funds (ETFs) have sprung to prominence, allowing for less risky investment in crypto. Another way you can get exposure to cryptocurrencies is through crypto contracts for difference (CFDs), a form of trading that gives you the chance to hedge your bets on the future performance of an asset without owning the underlying asset.

Cryptocurrency exchanges and brokers

To trade in cryptocurrency directly, as opposed to investing in a fund, you have two choices: use an exchange or a FOREX broker. With an exchange, you are buying and selling bitcoins or altcoins directly. In contrast, with a FOREX broker, you are buying a CFD. For this reason, and for portability as well, many cryptocurrency traders prefer exchanges – and sometimes utilize more than one exchange at once.

The workings of a cryptocurrency trade depend on the marketplace or exchange, but usually are either similar to stock-market broker trades, with buyers and sellers each posting their respective orders at set prices and quantities, or are like buying from a market maker who buys and sells to traders at a fixed price that is usually close to the market price.

A full-featured exchange, like GDAX, provides traders with an experience nearer to what they might encounter with an online broker, including posted bid-and-ask prices that indicate the price at which traders are willing to trade, as well as the quantity. 

How do you make a profit on a trade?

Much like stock market trading or FOREX trading, gains or losses on cryptocurrency are on paper – or its digital equivalent – and are only realized when an exchange event or sale actually takes place.

It may seem oxymoronic to discuss long-term trends with cryptocurrency when the second most popular currency is less than a few years old. However, when viewing the chart prices of the leading cryptocurrencies since their inception, the overall trend has generally been upward. Many cryptocurrency traders do not trade much at all. Instead, they bet large parts of their position on long-term gains, sometimes known as swing trading.

Special Considerations

The key to the functionality and allure of Bitcoin and other cryptocurrencies is the blockchain technology that is used to keep an online ledger of all the transactions that have ever been conducted. This provides a data structure for this ledger that is quite secure and is shared and agreed upon by the entire network of individual nodes or computers maintaining a copy of the ledger. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories. 

Meanwhile, many industry insiders see blockchain technology as having momentous potential for other uses, such as crowdfunding and online voting, and major financial institutions like JPMorgan Chase see the potential to lower transaction costs by streamlining payment processing. However, because cryptocurrencies are virtual and are not stored on a central database, a digital cryptocurrency balance can be wiped out simply by the loss or destruction of a hard drive if a backup copy of the private key does not exist. There are ways to keep your crypto safe. We should also say that the crypto space can be exposed to crypto scams, so you should always be on alert.

Advantages and Disadvantages of Cryptocurrencies

Advantages

Cryptocurrencies hold the promise of making it easier to transfer funds directly between two parties without the need for a trusted third party, like a bank or credit card company. These transfers are instead secured by the use of public keys and private keys, as well as different forms of incentive systems, like proof of work or proof of stake.

In modern cryptocurrency systems, a user's “wallet,” or account address, has a public key, while the private key is known only to the owner and is used to sign transactions. Fund movements are completed with minimal processing fees, allowing users to avoid the high fees charged by banks and financial institutions for wire transfers.

Disadvantages

The quasi-anonymous nature of cryptocurrency transactions makes them ideal for a host of illicit activities, such as money laundering and tax evasion, to name a few. However, cryptocurrency proponents often value their anonymity, citing the benefits of privacy protection for whistleblowers or activists living under repressive regimes. Note that some cryptocurrencies are more private than others. Bitcoin, for instance, is a relatively poor choice for conducting illegal business online. More privacy-oriented coins do exist, however, such as Dash, Monero or ZCash, which are far more difficult to trace.

Regulation of Cryptocurrencies Around the World

With technology continuing its brash integration into every aspect of our lives, regulators around the globe are struggling to keep up with the exasperating pace of balancing top-notch technology with the use of traditional regulatory schemes, leading to many questioning when crypto will become mainstream. 

As the technology sector exists in a constant state of growth and advancement, it is essential for regulators to steadily monitor and apprehend market dynamics in order to tailor traditional infrastructure to best suit the needs of the industry. While the financial sector is no stranger to technological development, the growing popularity of such technology as blockchain and cryptocurrencies has forced financial institutions to quickly face the transformative era of financial technology.

One of the most unique characteristics of cryptocurrencies is that they operate without a central regulatory authority. Traditional banking runs the risk of slow approval processes and high fees for transactions that may take days to complete. Decentralization in the case of crypto allows for financial transactions to take place nearly instantly with little-to-no fees mitigates bank failures, and offers the benefit of utilizing wallets that store cryptocurrencies offline (cold storage). This further safeguards consumers from data violations.

However, this does not mean cryptocurrencies should go unregulated. In spite of, or perhaps because of these unique attributes, regulators around the world are trying hard to determine how to best apply regulations to cryptocurrencies. In some countries, like Switzerland and Malta, for example, advanced legislation has already been enacted, setting the legislative framework for other nations building their own cryptocurrency regulations; while for many others countries, regulations do not even yet exist. Recently, with Donald Trump assuming the office of the US Presidency for the second time, the US has vowed to become a leader in the crypto regulation space.

As you would expect, regulation is important for several reasons. Regulators rightfully have an interest in overseeing the use of cryptocurrencies to minimize such risks as market manipulation, breaches in customer security and the use of cryptocurrencies in illegal activities, among others. Regulators are working to determine the best method that balances between reducing the risks associated with utilizing cryptocurrencies and minimizing the benefits of the mechanism.

Maltese and Swiss regulations

Malta was the first EU-member state to enact a comprehensive legal framework regulating DLTs, Virtual Financial Assets (VFA) and entities providing certain services related to VFAs. In 2018, the Maltese parliament issued three acts, the first of their kind: the Malta Digital Innovation Authority Act, the Innovative Technology Arrangements and Services Act and the Virtual Financial Assets Act (VFA Act). Collectively, this triumvirate of legislation provides a model framework for the industry regarding DLT software, the offering and issuing of VFAs and the provision of certain services connected to VFAs. The VFA Act qualifies all forms of cryptocurrencies as DLT assets and defines assets that are “intrinsically dependent on, or utilizes, Distributed Ledger Technology.” DLT assets can either be:

• Virtual Tokens, also known as utility tokens.

• Virtual Financial Assets.

• Electronic Money.

• Financial Instruments.

The VFA Act also outlines the Maltese Financial Instruments Test, used to determine under which category a DLT asset falls and must be performed by all companies issuing DLT assets in or from Malta, as well as persons conducting activities that fall within the scope of the VFA Act or other DLT-related legislation.

Meanwhile, in Switzerland, the Swiss Federal Council stated that the current best approach is to depend on categories of tokens, which were introduced by the Swiss Financial Market Supervisory Authority (FINMA) in its guidelines issued on 16 February 2018. The categories of tokens include: 

1. Payment tokens.

2. Utility tokens. 

3. Asset tokens.

Payment tokens, which FINMA considers synonymous with “pure cryptocurrencies,” involve cryptocurrencies that are intended to be used as a means of payment to acquire goods or services. When compared to traditional financial instruments, these most closely correspond with currencies. Utility tokens include tokens intended to provide digital access to an application or service by means of a blockchain-based infrastructure. Asset tokens, also referred to as stable coins, represent assets such as debt or equity claims against the issuer and are analogous to equities, bonds or derivatives. In this vein, FINMA stated that tokens enabling physical assets to be traded on a blockchain-infrastructure also fall within this category.

The UK and Germany are among the other countries that have also implemented legislation categorizing cryptocurrencies under different groups of tokens. Arincen will continue to monitor whether this modern view of banking techniques will catch hold in other Western countries and the world at large.

Cryptocurrency Scams

Cryptocurrency scams have become a popular way for scammers to trick people into sending money. While they pop up in many styles, and can target you regardless of your crypto trading strategy, most crypto scams appear as emails trying to blackmail someone, online chain referral schemes or bogus investment and business opportunities. Cryptocurrency-related fraud has seen a significant increase in recent years. In 2019, scams resulted in losses exceeding $4 billion. This figure has escalated substantially, with the FBI reporting that in 2023, losses from cryptocurrency-related frauds and scams totaled more than $5.6 billion, marking a 45% increase from the previous year.

Cryptojacking

Cryptojacking is the unauthorized use of someone else’s computer to mine cryptocurrency. Hackers do this either by getting the victim to click on a malicious link in an email that loads cryptomining code on the computer, or by infecting a website or online ad with JavaScript code that auto-executes once loaded in the victim’s browser. In either case, the cryptomining code then works in the background as unsuspecting victims use their computers normally. The only sign they might notice is slower performance or lags in execution.

How cryptojacking works

Hackers have two principal methods to get a victim’s computer to secretly mine cryptocurrencies. One is to trick victims into loading crypto mining code onto their computers. This is done through phishing-like tactics: Victims receive a legitimate-looking email that encourages them to click on a link. The link then runs a code that places the crypto mining script on the computer and it then runs in the background as the victim works.

The other practice is to inject a script on a website or an ad that is delivered to multiple websites. Once victims visit the website or the infected ad pops up in their browsers, the script automatically executes. No code is stored on the victims’ computers. Whichever method is used, the code runs complex mathematical problems on the victims’ computers and sends the results to a server that the hacker controls.

Why is cryptojacking popular?

No one knows for certain how much cryptocurrency is mined through cryptojacking, but there is no question that the practice is widespread. Browser-based cryptojacking grew fast at first, but seems to be tapering off, most likely because of both cryptocurrency volatility and the closing in March 2019 of Coinhive, the most popular JavaScript miner that was also used for legitimate crypto mining activity. The 2020 SonicWall Cyber Threat Report divulged that the volume of crypto hacking attacks fell 78% in the second half of 2019 as a result of the Coinhive closure.

The decline began earlier, however. Positive Technology's Cybersecurity Threatscape Q1 2019 report shows that cryptomining now accounts for only 7% of all attacks, down from 23% in early 2018. The report suggests that cybercriminals have shifted more to ransomware, which is believed to be more profitable.

In January 2018, researchers discovered the Smominru crypto mining botnet, which infected more than a half a million machines, primarily in Russia, India and Taiwan. The botnet targeted Windows servers to mine Monero, and cybersecurity firm Proofpoint estimated the botnet had generated as much as $3.6 million in value as of the end of January 2018.

Cryptojacking does not even require significant technical skills. According to the report, The New Gold Rush Cryptocurrencies Are the New Frontier of Fraud, from Digital Shadows, cryptojacking kits are available on the dark Web for as little as $30.

The straightforward reason why cryptojacking is becoming more popular with hackers is more money for less risk. The risk of being caught and identified is also much less than with ransomware. The cryptomining code runs covertly and can go undetected for a long time. Once discovered, it is very hard to trace back to the source, and the victims have little incentive to do so since nothing was stolen or encrypted. Hackers tend to prefer anonymous cryptocurrencies, like Monero and Zcash, over the more popular Bitcoin because it is harder to track the illegal activity back to them.

How to prevent cryptojacking

Follow these two elementary steps to minimize the risk of your organization falling victim to cryptojacking:

• Incorporate the cryptojacking threat into your security awareness training, focusing on phishing-type attempts to load scripts onto users’ computers; and 

• Install an ad-blocking or anti-crypto mining extension on web browsers. Since cryptojacking scripts are often delivered through web ads, installing an ad blocker can be an effective means of stopping them. Some ad blockers have some capability to detect crypto mining scripts. Laliberte recommends extensions like No Coin and MinerBlock, which are designed to detect and block crypto mining scripts.

Criticism of Cryptocurrencies

Prices for cryptocurrencies based on the forces of supply and demand, the rate at which a cryptocurrency can be exchanged for another currency can vary widely. This is especially true because the design of many cryptocurrencies ensures a high degree of scarcity. 

Bitcoin has experienced some rapid surges and collapses in value, climbing as high as $19,000 per Bitcoin in December 2017 before dropping to around $7,000 in the following months. Today, Bitcoin is worth $104,000 per coin. Cryptocurrencies are therefore considered by some economists to be a short-lived fad or speculative bubble. Further, there is growing concern that cryptocurrencies like Bitcoin are not rooted in any material goods. 

Cryptocurrency blockchains are highly secure, but other aspects of a cryptocurrency ecosystem, including exchanges and wallets, are not protected from the threat of hacking. In fact, in Bitcoin's history, several online exchanges have been the subject of hacking and theft, sometimes with millions of dollars’ worth of “coins” stolen.

In spite of that, many observers see potential advantages in cryptocurrencies, like the possibility of hedging against high inflation and facilitating exchange while being easier to transport and divide than precious metal, and, further, existing outside the influence of central banks and governments.

The Future of Cryptocurrencies

The future of cryptocurrencies is shaping up to be a mix of innovation, regulation, and market cycles—just like any other financial evolution. While the wild speculation and boom-and-bust cycles aren’t going away anytime soon, we’re likely to see greater institutional adoption, more refined use cases, and increased regulatory oversight.

Central banks are already exploring digital currencies (CBDCs), which could either compete with or legitimize crypto further. Meanwhile, blockchain technology is expanding beyond finance, with real-world applications in supply chains, gaming, and smart contracts. However, crypto’s future still depends on mass adoption, security improvements, and how governments decide to regulate (or embrace) digital assets. Whether as an investment, a decentralized alternative to traditional finance, or the backbone of Web3, crypto isn’t disappearing anytime soon.

Conclusion

Cryptocurrencies are a groundbreaking innovation, however, they are still a relatively young experiment in the financial world. While it’s clear they’re here to stay, it’s unlikely they will fully replace fiat currencies anytime soon. That said, as we’ve explored in this article, crypto has sparked important discussions about how money is governed, the role of financial intermediaries, and what truly defines a currency. Whether they complement traditional finance or challenge it outright, cryptocurrencies have reshaped the conversation around monetary policy, regulation, and the future of global finance.
