How a cryptocurrency works
Cryptocurrencies are legal in the European Union. Derivatives and other products that use cryptocurrencies will need to qualify as "financial instruments. Within the United States, the biggest and most sophisticated financial market in the world, crypto derivatives such as Bitcoin futures are available on the Chicago Mercantile Exchange.
This stance implies that cryptocurrency's legal status may become subject to regulation. Although cryptocurrencies are considered a form of money, the Internal Revenue Service IRS treats them as a financial asset or property. And, as with most other investments, if you reap capital gains in selling or trading cryptocurrencies, the government wants a piece of the profits.
On May 20, , the U. How exactly the IRS would tax proceeds—as capital gains or ordinary income—depends on how long the taxpayer held the cryptocurrency. Are Cryptocurrencies Safe Investments? Cryptocurrencies have attracted a reputation as unstable investments, due to high investor losses as a result of scams, hacks, and bugs. Although the underlying cryptography is generally secure, the technical complexity of using and storing crypto assets can be a major hazard to new users.
In addition to the market risks associated with speculative assets, cryptocurrency investors should be aware of the following risks: User risk: Unlike traditional finance, there is no way to reverse or cancel a cryptocurrency transaction after it has already been sent. By some estimates, about a fifth of all bitcoins are now inaccessible due to lost passwords or incorrect sending addresses. Regulatory risks: The regulatory status of some cryptocurrencies is still unclear, with many governments seeking to regulate them as securities, currencies, or both.
A sudden regulatory crackdown could make it difficult to sell cryptocurrencies, or cause a market-wide price drop. Counterparty risks: Many investors and merchants rely on exchanges or other custodians to store their cryptocurrency. Theft or loss by one of these third parties could result in the loss of one's entire investment.
Management risks: Due to the lack of coherent regulations, there are few protections against deceptive or unethical management practices. Many investors have lost large sums to management teams that failed to deliver a product. Programming risks: Many investment and lending platforms use automated smart contracts to control the movement of user deposits.
An investor using one of these platforms assumes the risk that a bug or exploit in these programs could cause them to lose their investment. Market Manipulation: Market manipulation remains a substantial problem in the cryptocurrency space, and some exchanges have been accused of manipulating prices or trading against their customers. Despite the speculative nature of the asset, some have been able to create substantial fortunes by taking on the risk of investing in early-stage cryptocurrencies.
Advantages and Disadvantages of Cryptocurrency Cryptocurrencies were introduced with the intent to revolutionize financial infrastructure. As with every revolution, however, there are tradeoffs involved. At the current stage of development for cryptocurrencies, there are many differences between the theoretical ideal of a decentralized system with cryptocurrencies and its practical implementation.
Some advantages and disadvantages of cryptocurrencies are as follows. Advantages Cryptocurrencies represent a new, decentralized paradigm for money. In this system, centralized intermediaries, such as banks and monetary institutions, are not necessary to enforce trust and police transactions between two parties. Thus, a system with cryptocurrencies eliminates the possibility of a single point of failure, such as a large bank, setting off a cascade of crises around the world, such as the one that was triggered in by the failure of institutions in the United States.
Cryptocurrencies promise to make it easier to transfer funds directly between two parties, without the need for a trusted third party like a bank or a credit card company. Such decentralized transfers are secured by the use of public keys and private keys and different forms of incentive systems, such as proof of work or proof of stake.
Because they do not use third-party intermediaries, cryptocurrency transfers between two transacting parties are faster as compared to standard money transfers. Flash loans in decentralized finance are a good example of such decentralized transfers.
These loans, which are processed without backing collateral, can be executed within seconds and are used in trading. Cryptocurrency investments can generate profits. The remittance economy is testing one of cryptocurrency's most prominent use cases. Currently, cryptocurrencies such as Bitcoin serve as intermediate currencies to streamline money transfers across borders. Thus, a fiat currency is converted to Bitcoin or another cryptocurrency , transferred across borders, and, subsequently, converted to the destination fiat currency.
This method streamlines the money transfer process and makes it cheaper. Disadvantages Though they claim to be an anonymous form of transaction, cryptocurrencies are actually pseudonymous. This opens up possibilities of governments or federal authorities tracking the financial transactions of ordinary citizens. Cryptocurrencies have become a popular tool with criminals for nefarious activities such as money laundering and illicit purchases.
The case of Dread Pirate Roberts , who ran a marketplace to sell drugs on the dark web, is already well known. Cryptocurrencies have also become a favorite of hackers who use them for ransomware activities. In theory, cryptocurrencies are meant to be decentralized, their wealth distributed between many parties on a blockchain. In reality, ownership is highly concentrated. One of the conceits of cryptocurrencies is that anyone can mine them using a computer with an Internet connection.
However, mining popular cryptocurrencies requires considerable energy, sometimes as much energy as entire countries consume. The expensive energy costs coupled with the unpredictability of mining have concentrated mining among large firms whose revenues running into the billions of dollars. Though cryptocurrency blockchains are highly secure, other crypto repositories, such as exchanges and wallets, can be hacked. Many cryptocurrency exchanges and wallets have been hacked over the years, sometimes resulting in millions of dollars worth of "coins" stolen.
Cryptocurrencies traded in public markets suffer from price volatility. Some economists thus consider cryptocurrencies to be a short-lived fad or speculative bubble. How Do You Buy Cryptocurrencies? Any investor can purchase cryptocurrency from popular crypto exchanges such as Coinbase, apps such as Cash App, or through brokers. Another popular way to invest in cryptocurrencies is through financial derivatives, such as CME's Bitcoin futures, or through other instruments, such as Bitcoin trusts and Bitcoin ETFs.
What Is the Point of Cryptocurrency? Cryptocurrencies are a new paradigm for money. Their promise is to streamline existing financial architecture to make it faster and cheaper. Their technology and architecture decentralize existing monetary systems and make it possible for transacting parties to exchange value and money independently of intermediary institutions such as banks.
Can You Generate Cryptocurrency? Cryptocurrencies are generated by mining. It is built this way so that taking part in the network is far more economically incentivized than attacking it. Bitcoin vs. Blockchain Blockchain technology was first outlined in by Stuart Haber and W. Scott Stornetta, two researchers who wanted to implement a system where document timestamps could not be tampered with. The Bitcoin protocol is built on a blockchain.
As discussed above, this could be in the form of transactions, votes in an election, product inventories, state identifications, deeds to homes, and much more. Currently, tens of thousands of projects are looking to implement blockchains in a variety of ways to help society other than just recording transactions—for example, as a way to vote securely in democratic elections. For example, a voting system could work such that each citizen of a country would be issued a single cryptocurrency or token.
Each candidate would then be given a specific wallet address, and the voters would send their token or crypto to the address of whichever candidate for whom they wish to vote. The transparent and traceable nature of blockchain would eliminate both the need for human vote counting and the ability of bad actors to tamper with physical ballots.
Blockchain vs. Banks Blockchains have been heralded as being a disruptive force to the finance sector, and especially with the functions of payments and banking. However, banks and decentralized blockchains are vastly different. How Are Blockchains Used? Today, there are more than 10, other cryptocurrency systems running on blockchain. But it turns out that blockchain is actually a reliable way of storing data about other types of transactions as well.
For example, IBM has created its Food Trust blockchain to trace the journey that food products take to get to their locations. Why do this? The food industry has seen countless outbreaks of E. In the past, it has taken weeks to find the source of these outbreaks or the cause of sickness from what people are eating.
If a food is found to be contaminated, then it can be traced all the way back through each stop to its origin. Not only that, but these companies can also now see everything else it may have come in contact with, allowing the identification of the problem to occur far sooner and potentially saving lives.
This is one example of blockchain in practice, but there are many other forms of blockchain implementation. Banking and Finance Perhaps no industry stands to benefit from integrating blockchain into its business operations more than banking. Financial institutions only operate during business hours, usually five days a week.
That means if you try to deposit a check on Friday at 6 p. Even if you do make your deposit during business hours, the transaction can still take one to three days to verify due to the sheer volume of transactions that banks need to settle. Blockchain, on the other hand, never sleeps.
By integrating blockchain into banks, consumers can see their transactions processed in as little as 10 minutes—basically the time it takes to add a block to the blockchain, regardless of holidays or the time of day or week. With blockchain, banks also have the opportunity to exchange funds between institutions more quickly and securely. In the stock trading business, for example, the settlement and clearing process can take up to three days or longer, if trading internationally , meaning that the money and shares are frozen for that period of time.
Given the size of the sums involved, even the few days that the money is in transit can carry significant costs and risks for banks. Currency Blockchain forms the bedrock for cryptocurrencies like Bitcoin. The U. In , several failing banks were bailed out—partially using taxpayer money. These are the worries out of which Bitcoin was first conceived and developed. By spreading its operations across a network of computers, blockchain allows Bitcoin and other cryptocurrencies to operate without the need for a central authority.
This not only reduces risk but also eliminates many of the processing and transaction fees. It can also give those in countries with unstable currencies or financial infrastructures a more stable currency with more applications and a wider network of individuals and institutions with whom they can do business, both domestically and internationally.
Using cryptocurrency wallets for savings accounts or as a means of payment is especially profound for those who have no state identification. Some countries may be war-torn or have governments that lack any real infrastructure to provide identification. Citizens of such countries may not have access to savings or brokerage accounts—and, therefore, no way to safely store wealth.
When a medical record is generated and signed, it can be written into the blockchain, which provides patients with the proof and confidence that the record cannot be changed. These personal health records could be encoded and stored on the blockchain with a private key, so that they are only accessible by certain individuals, thereby ensuring privacy.
In the case of a property dispute, claims to the property must be reconciled with the public index. This process is not just costly and time-consuming—it is also prone to human error, where each inaccuracy makes tracking property ownership less efficient.
Blockchain has the potential to eliminate the need for scanning documents and tracking down physical files in a local recording office. If property ownership is stored and verified on the blockchain, owners can trust that their deed is accurate and permanently recorded.
If a group of people living in such an area is able to leverage blockchain, then transparent and clear time lines of property ownership could be established. Smart Contracts A smart contract is a computer code that can be built into the blockchain to facilitate, verify, or negotiate a contract agreement. Smart contracts operate under a set of conditions to which users agree. When those conditions are met, the terms of the agreement are automatically carried out. Say, for example, that a potential tenant would like to lease an apartment using a smart contract.
The landlord agrees to give the tenant the door code to the apartment as soon as the tenant pays the security deposit. Both the tenant and the landlord would send their respective portions of the deal to the smart contract, which would hold onto and automatically exchange the door code for the security deposit on the date when the lease begins.
This would eliminate the fees and processes typically associated with the use of a notary, a third-party mediator, or attorneys. Supply Chains As in the IBM Food Trust example, suppliers can use blockchain to record the origins of materials that they have purchased. Voting As mentioned above, blockchain could be used to facilitate a modern voting system. Voting with blockchain carries the potential to eliminate election fraud and boost voter turnout, as was tested in the November midterm elections in West Virginia.
Using blockchain in this way would make votes nearly impossible to tamper with. The blockchain protocol would also maintain transparency in the electoral process, reducing the personnel needed to conduct an election and providing officials with nearly instant results. This would eliminate the need for recounts or any real concern that fraud might threaten the election.
From greater user privacy and heightened security to lower processing fees and fewer errors, blockchain technology may very well see applications beyond those outlined above. But there are also some disadvantages. Pros Improved accuracy by removing human involvement in verification Cost reductions by eliminating third-party verification Decentralization makes it harder to tamper with Transactions are secure, private, and efficient Transparent technology Provides a banking alternative and a way to secure personal information for citizens of countries with unstable or underdeveloped governments Cons Significant technology cost associated with mining bitcoin Low transactions per second History of use in illicit activities, such as on the dark web Regulation varies by jurisdiction and remains uncertain Data storage limitations Benefits of Blockchains Accuracy of the Chain Transactions on the blockchain network are approved by a network of thousands of computers.
This removes almost all human involvement in the verification process, resulting in less human error and an accurate record of information. Even if a computer on the network were to make a computational mistake, the error would only be made to one copy of the blockchain.
Cost Reductions Typically, consumers pay a bank to verify a transaction, a notary to sign a document, or a minister to perform a marriage. Blockchain eliminates the need for third-party verification—and, with it, their associated costs. For example, business owners incur a small fee whenever they accept payments using credit cards, because banks and payment-processing companies have to process those transactions.
Bitcoin, on the other hand, does not have a central authority and has limited transaction fees. Decentralization Blockchain does not store any of its information in a central location. Instead, the blockchain is copied and spread across a network of computers.
Whenever a new block is added to the blockchain, every computer on the network updates its blockchain to reflect the change. By spreading that information across a network, rather than storing it in one central database, blockchain becomes more difficult to tamper with. If a copy of the blockchain fell into the hands of a hacker, only a single copy of the information, rather than the entire network, would be compromised.
Efficient Transactions Transactions placed through a central authority can take up to a few days to settle. If you attempt to deposit a check on Friday evening, for example, you may not actually see funds in your account until Monday morning. Whereas financial institutions operate during business hours, usually five days a week, blockchain is working 24 hours a day, seven days a week, and days a year.
Transactions can be completed in as little as 10 minutes and can be considered secure after just a few hours. This is particularly useful for cross-border trades, which usually take much longer because of time zone issues and the fact that all parties must confirm payment processing. Although users can access details about transactions, they cannot access identifying information about the users making those transactions.
It is a common misperception that blockchain networks like bitcoin are anonymous, when in fact they are only confidential. When a user makes a public transaction, their unique code—called a public key, as mentioned earlier—is recorded on the blockchain. Their personal information is not. Secure Transactions Once a transaction is recorded, its authenticity must be verified by the blockchain network.
Thousands of computers on the blockchain rush to confirm that the details of the purchase are correct. After a computer has validated the transaction, it is added to the blockchain block. Each block on the blockchain contains its own unique hash, along with the unique hash of the block before it. This discrepancy makes it extremely difficult for information on the blockchain to be changed without notice.
Transparency Most blockchains are entirely open-source software. This means that anyone and everyone can view its code. This gives auditors the ability to review cryptocurrencies like Bitcoin for security. Because of this, anyone can suggest changes or upgrades to the system. If a majority of the network users agree that the new version of the code with the upgrade is sound and worthwhile, then Bitcoin can be updated. Banking the Unbanked Perhaps the most profound facet of blockchain and Bitcoin is the ability for anyone, regardless of ethnicity, gender, or cultural background, to use it.
According to The World Bank, an estimated 1. Nearly all of these individuals live in developing countries, where the economy is in its infancy and entirely dependent on cash. These people often earn a little money that is paid in physical cash. They then need to store this physical cash in hidden locations in their homes or other places of living, leaving them subject to robbery or unnecessary violence. Keys to a bitcoin wallet can be stored on a piece of paper, a cheap cell phone, or even memorized if necessary.
For most people, it is likely that these options are more easily hidden than a small pile of cash under a mattress. Blockchains of the future are also looking for solutions to not only be a unit of account for wealth storage but also to store medical records, property rights, and a variety of other legal contracts.
Drawbacks of Blockchains Technology Cost Although blockchain can save users money on transaction fees, the technology is far from free. For example, the PoW system which the bitcoin network uses to validate transactions, consumes vast amounts of computational power. In the real world, the power from the millions of computers on the bitcoin network is close to what Norway and Ukraine consume annually.
Despite the costs of mining bitcoin, users continue to drive up their electricity bills to validate transactions on the blockchain. When it comes to blockchains that do not use cryptocurrency, however, miners will need to be paid or otherwise incentivized to validate transactions. Some solutions to these issues are beginning to arise.

Cold storage, on the other hand, is safer but makes it harder to transact. Transacting or investing Cryptocurrencies like Bitcoins can be easily transferred from one digital wallet to another, using only a smartphone. Once you own them, your choices are to: a use them to buy goods or services b trade in them c exchange them for cash If you are using Bitcoin for purchases, the easiest way to do that is through debit-card-type transactions.
You can also use these debit cards to withdraw cash, just like at an ATM. Converting cryptocurrency to cash is also possible using banking accounts or peer-to-peer transactions. Types of Cryptocurrencies There are tens of thousands of cryptocurrencies available today with the figure pegged at 10, in Bitcoin is so popular, there was a time when its name was synonymous with cryptocurrency.
But potential investors need to know bitcoins have become very expensive. Altcoin Altcoin is the term used for any alternative digital currency to bitcoin. The most popular in this ecosystem is Ethereum — one of the fastest-growing cryptocurrencies in the market. There is also a range of other altcoins in the market today such as Luckyblock, Shiba Inu and Terra.
Crypto tokens The concept of crypto coins vs tokens can be confusing to many. At first glance, coins and tokens appear the same. However, the two have many differences Coins can be mined, but tokens cannot be mined. Coins are linked to blockchains, tokens are not.
In terms of utility, they vary in the type of product or service they allow users to purchase. Should You Invest In Cryptocurrency? There are many advantages to dealing in cryptocurrencies, and a fair share of disadvantages as well. Here are the top three reasons that work in favor of and against cryptocurrencies.
Advantages: They are private and secure: The blockchain technology that fuels cryptocurrencies ensures user anonymity. It also assures high levels of security through cryptography, which we discussed before. They are decentralized, immutable, and transparent: The entire system functions on shared ownership, where data is available to all permissioned members and is tamper-proof. They are a hedge against inflation: Cryptocurrency makes for a great investment in times of inflation.
For example, investors often compare cryptocurrency to gold. One of the reasons behind this is that, just like gold, they are in limited supply, as there is a cap on mining any type of cryptocurrency. Disadvantages: They are not widely understood: They are a relatively new concept and the long-term sustainability of cryptocurrencies remains to be seen.
They are prone to high risks: Needless to say, cryptocurrencies bring in as many rewards as risks. Their highly volatile and speculative nature makes them prone to sharp downward spirals. Investing in cryptocurrency can be risky for many reasons. A major deterrent could be the fact that digital currency seems to have no inherent or underlying value.
There is a supply-demand type of equation that is used to determine the value of cryptos like bitcoins. Plus, it is easy to see how simple speculations over the internet can result in a substantial rise or loss of value of these coins. Also the fact that cryptocurrencies are banned or their usage restricted in a lot of countries plays out as a significant risk.
Their legality is debatable in countries like India. Scalability is a problem: This is a complex issue, which has more to do with the technology side of the blockchain. Simply put, the sluggish nature of the blockchain makes it prone to transactional delays. This has the tendency to make crypto payments inefficient when compared to modern-day electronic payment techniques. Cryptocurrency in India Until the Union Budget announcement, the fate of cryptocurrency in India was largely undecided.
It set off the debate on whether or not the tax on cryptocurrency indicates the government has recognized it as a legitimate form of currency. Bottom Line Whether cryptocurrency is the future of money or not, one thing is clear: It is not advisable for anyone to invest in it without doing enough research. Investing in cryptocurrencies is not a new phenomenon.
But with the recent surge in popularity and value, coupled with falling returns on bank deposits, more people are looking for cryptocurrency advice. If you have decided to invest in cryptocurrencies, ensure that you start with the leading cryptocurrencies like bitcoin, as newer ones may not have sufficient liquidity you may not be able to sell them when you want to.
The market is rife with scamsters. Hence using authorized platforms to buy or trade cryptos is important, especially while starting out. Investing in cryptocurrency is a risky venture. After all, cryptocurrency is a digital currency, where transactions are recorded on a public digital ledger called a blockchain, and every process along the way is secured by cryptography. The goal of this page will be to help you understand these things and how they connect. Cryptocurrency works a lot like bank credit on a debit card.
In both cases, a complex system that issues currency and records transactions and balances works behind the scenes to allow people to send and receive currency electronically. Likewise, just like with banking, online platforms can be used to manage accounts and move balances.
The main difference between cryptocurrency and bank credit is that instead of banks and governments issuing the currency and keeping ledgers, an algorithm does. What is cryptocurrency? Cryptocurrency is best thought of as digital currency it only exists on computers.
It is transferred between peers there is no middleman like a bank. It is decentralized, meaning it is controlled by users and computer algorithms and not a central government. It is distributed, meaning the blockchain is hosted on many computers across the globe.
Meanwhile, cryptocurrencies are traded on online cryptocurrency exchanges , like stock exchanges. To transfer funds, knowledge of a password AKA a private key associated with the account is needed. The transaction amounts are public, but who sent the transaction is encrypted transactions are pseudo-anonymous. Each transaction leads back to a unique set of keys. Whoever owns a set of keys, owns the amount of cryptocurrency associated with those keys just like whoever owns a bank account owns the money in it.
Many transactions are added to a ledger at once. However, some altcoins use unique mechanics. How does blockchain work? The blockchain is like a decentralized bank ledger, in both cases, the ledger is a record of transactions and balances. When a cryptocurrency transaction is made, that transaction is sent out to all users hosting a copy of the blockchain.
Sometimes miners pool computing power and share the new coins. The algorithm relies on consensus. If the majority of users trying to solve the puzzle all submit the same transaction data, then it confirms that the transactions are correct. Further, the security of the blockchain relies on cryptography.
Each block is connected to the data in the last block via one-way cryptographic codes called hashes which are designed to make tampering with the blockchain very difficult. Offering new coins as rewards, the difficulty of cracking the cryptographic puzzles, and the amount of effort it would take to add incorrect data to the blockchain by faking consensus or tampering with the blockchain, helps to ensure against bad actors.
What is cryptocurrency mining? People who are running software and hardware aimed at confirming transactions to the digital ledger are cryptocurrency miners. Solving cryptographic puzzles via software to add transactions to the ledger the blockchain in the hope of getting coins as a reward is cryptocurrency mining. How does cryptography work with cryptocurrency? The keys that move balances around the blockchain utilize a type of one-way cryptography called public-key cryptography.
How does one obtain or trade cryptocurrency? Cryptocurrency can be obtained most of the same ways other types of currencies can.
