Cryptocurrencies 101: A Beginner's Guide to Understanding the Basics

Cryptocurrencies have been around for over a decade, with the first one, Bitcoin, launched in 2009.

The total supply of Bitcoin is capped at 21 million, which helps prevent inflation and maintain its value.

The first cryptocurrency, Bitcoin, was created by an individual or group using the pseudonym Satoshi Nakamoto.

The decentralized nature of cryptocurrencies means that transactions are recorded on a public ledger called a blockchain, which is maintained by a network of computers around the world.

Cryptocurrencies are digital or virtual currencies secured by cryptography, making them nearly impossible to counterfeit or double-spend.

They exist on decentralized networks using blockchain technology, a distributed ledger enforced by a disparate network of computers.

A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.

Here are the six conditions that define a cryptocurrency, as outlined by Jan Lansky:

You can use cryptocurrency to pay for everyday things, like buying a new pair of socks or booking flights and hotels for your next holiday.

A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block contains a hash pointer as a link to a previous block, a timestamp, and transaction data.

The data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. This makes blockchain technology inherently resistant to modification.

A blockchain is managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. This decentralized consensus has been achieved with a blockchain.

Here are some key concepts related to blockchain:

A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp, and transaction data.

Blockchain technology is designed to be secure by nature, with an inherent resistance to modification of the data. This is achieved through a decentralized consensus mechanism, where a peer-to-peer network collectively adheres to a protocol for validating new blocks.

The blockchain ledger is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. This eliminates the need for a trusted third party to verify transactions.

Here are some key features of a blockchain:

By design, blockchains are inherently resistant to modification of the data, making them a secure way to record transactions. This is achieved through a combination of cryptography and decentralized consensus.

Atomic swaps are a mechanism where one cryptocurrency can be exchanged directly for another cryptocurrency without the need for a trusted third party, such as an exchange.

This means that users can trade cryptocurrencies without having to rely on a central authority, giving them more control over their transactions.

Atomic swaps are a decentralized way to exchange cryptocurrencies, allowing users to bypass traditional exchange services.

Decentralized exchanges are often more secure and less prone to hacks, making them an attractive option for users who value their security.

Atomic swaps can be used to exchange a wide range of cryptocurrencies, from popular coins like Bitcoin and Ethereum to smaller, niche cryptocurrencies.

Cryptocurrencies have various purposes, and understanding these types can help you decide whether to invest in them. A cryptocurrency with a purpose is likely to be less risky than one without a use.

Many cryptocurrencies were created to serve specific functions on their respective blockchains. For example, Ethereum's ether was designed to be used as payment for validating transactions and opening blocks.

Some cryptocurrencies have a clear purpose, such as XRP, which is designed for financial institutions to facilitate transfers between different geographies. Others, like Bitcoin, are primarily used as a payment method.

Here are some common types of cryptocurrencies:

Mining accelerator chips are a type of specialized hardware designed to increase the efficiency of cryptocurrency mining.

Numerous companies have developed these chips, which can perform at a much higher price-performance ratio than traditional CPU or GPU mining.

At one point, Intel even marketed its own brand of crypto accelerator chip, named Blockscale.

These chips have been a game-changer for miners, allowing them to process transactions faster and more efficiently.

The development of mining accelerator chips has led to an arms race for cheaper-yet-efficient machines, driving innovation in the field of cryptocurrency mining.

This has had significant environmental implications, with a 2023 IMF working paper estimating that crypto mining could generate 450 million tons of CO2 emissions by 2027.

Bitcoin is pseudonymous, not anonymous, meaning its owners aren't immediately identifiable, but transactions are publicly available in the blockchain.

Cryptocurrency exchanges are often required by law to collect users' personal information, making anonymity a complex issue.

Some cryptocurrencies, like Monero, Zerocoin, Zerocash, and CryptoNote, implement additional measures to increase privacy, such as using zero-knowledge proofs.

A 2020 study demonstrated that anonymity techniques in cryptocurrencies aren't sufficient safeguards against certain attacks.

Researchers suggested new cryptographic schemes and mechanisms to hide the IP address of the source to improve privacy.

Altcoins are alternative cryptocurrencies to bitcoin, often with underlying differences that set them apart. They emerged in the 2010s as a collective term for tokens, cryptocurrencies, and digital assets that weren't bitcoin.

More than 5,000 cryptocurrencies existed as of early 2020, showcasing the vast array of altcoins available. Altcoins can process transactions faster than bitcoin, with Litecoin confirming transactions every 2.5 minutes compared to bitcoin's 10 minutes.

Ethereum is a notable altcoin with smart contract functionality, allowing decentralized applications to run on its blockchain. It was the most used blockchain in 2020, according to Bloomberg News.

The term "altseason" refers to significant market price rallies across multiple altcoin markets.

Stablecoins are designed to maintain a stable level of purchasing power, but their designs are not foolproof.

Terra's stablecoin UST fell from $1 to 26 cents on 11 May 2022, resulting in a significant loss of value.

The subsequent failure of Terraform Labs led to the loss of nearly $40B invested in the Terra and Luna coins.

In September 2022, South Korean prosecutors requested the issuance of an Interpol Red Notice against the company's founder, Do Kwon.

Understanding the different types of cryptocurrencies can be overwhelming, but it's essential to make informed decisions when investing.

Ethereum's ether and XRP are examples of utility tokens, designed to serve specific functions on their respective blockchains.

Utility tokens are used for a specific purpose, such as facilitating transfers or validating transactions.

Transactional tokens, like Bitcoin, are designed to be used as a payment method.

Governance tokens, such as Uniswap, represent voting or other rights on a blockchain.

Platform tokens, like Solana, support applications built to use a blockchain.

Security tokens, like MS Token, represent ownership of an asset, such as a stock that has been tokenized.

Here are the different types of cryptocurrencies:

Staking is a type of cryptocurrency investment where you lock up your coins in a wallet to support the network and earn rewards.

By staking, you're essentially acting as a validator, verifying transactions and helping to secure the network. This process requires a significant amount of coins, as you need to hold a certain amount to participate.

The amount of coins required for staking varies depending on the network, but it's often around 32 Ethereum or 1,000 Tron. You'll also need to keep your coins in a wallet that supports staking, such as a Ledger or Trezor.

As a validator, you'll earn a percentage of the block reward, which is the new coins created by the network. This can be a lucrative way to earn passive income, especially if you have a large holding of coins.

However, staking also comes with some risks, such as the potential for your coins to be frozen or lost if the network is compromised. You'll need to do your research and choose a reputable wallet and network to minimize these risks.

Staking is a relatively low-risk investment compared to other types of cryptocurrency investments, such as mining or trading. It's also a great way to support the growth and development of the network.

A fresh viewpoint: Cryptocurrency Security Risks

Let's explore the common types of cryptocurrencies that you might have heard of.

Ethereum, for example, is one of the most well-known cryptocurrencies after Bitcoin. It's often used for decentralized applications and smart contracts.

Litecoin is another popular cryptocurrency that's similar to Bitcoin but with faster transaction times.

Cryptocurrencies are supported by a technology called blockchain, which keeps track of who owns what and prevents people from making copies of their holdings and attempting to spend it twice.

Individual units of cryptocurrencies can be referred to as coins or tokens, depending on how they are used.

Some cryptocurrencies are intended to be units of exchange for goods and services, while others are stores of value or used to participate in specific software programs such as games and financial products.

Cryptocurrencies are supported by a technology called blockchain, which keeps track of who owns what and maintains a tamper-resistant record of transactions.

Blockchain addressed a problem faced by previous digital currency efforts: preventing people from making copies of their holdings and trying to spend them twice.

Individual units of cryptocurrencies are referred to as coins or tokens, depending on how they are used. Some are meant to be units of exchange for goods and services, while others are stores of value or used to participate in specific software programs.

You can store your cryptocurrency in a wallet, which keeps your public and private keys or seed safe. These keys are essential for receiving or spending your cryptocurrency.

There are multiple methods to store your keys or seed, including paper wallets, hardware wallets, digital wallets, and even hosting your wallet on an exchange where cryptocurrency is traded.

Crypto can make money for you in various ways, but none of them are guaranteed. You can loan your crypto with interest through decentralized finance applications, or stake a compatible one on a blockchain or at certain exchanges for rewards.

Decentralized finance applications let you loan your crypto with interest, which is a way to earn money from your existing holdings. This is a relatively low-risk way to earn some extra cash.

You can also stake a compatible cryptocurrency on a blockchain or at certain exchanges for rewards. For example, the Ethereum Foundation's "The Merge" project aims to improve the efficiency of the Ethereum network, which could potentially increase the value of staked Ether.

Some people have benefitted from holding onto their cryptocurrencies and watching their market value increase. However, this method is highly speculative and comes with significant risks. As the article "Investing In The Millennium Sapphinre STO" by MSToken notes, investing in cryptocurrencies is a high-risk, high-reward game.

Here are some ways to make money with crypto:

One of the biggest advantages of cryptocurrencies is the speed of transactions. Your money can be with someone on the other side of the world within seconds.

This is especially impressive considering the cost, which is a fraction of what you'd pay for an international wire transfer.

Investing in cryptocurrencies is a long-term game, where investors look for growth in the fundamentals of the asset. You can start investing with as little as $15 and the onboarding process is smooth and quick.

To make informed investment decisions, it's essential to understand fundamental analysis (FA), which involves evaluating an investment's profit potential. You can also consider asset allocation and diversification to spread your risk.

If you're new to investing, it's worth exploring different strategies, such as dollar-cost averaging (DCA), which involves investing a fixed amount of money at regular intervals, regardless of the market's performance.

To buy cryptocurrency, you'll need to visit a cryptocurrency exchange, which allows you to buy or sell cryptocurrencies from other users at the current market price, similar to a stock.

You can also buy cryptocurrency as an investment through your brokerage, such as Robinhood, which allows users to invest in bitcoin and other cryptocurrencies, although you cannot withdraw them from the platform for purchases.

To buy cryptocurrency for purchases, you'll need to transfer it to a digital wallet or use a third-party service like Coinbase to store your coins.

There are also crypto ETFs that provide exposure to the crypto asset class without requiring the investors to maintain their own wallets, such as Bitcoin futures ETF shares, which were approved by the SEC as of May 2024.

If you're new to investing, you can start with as little as $15, and the onboarding process is smooth and quick.

Here are some popular options for buying cryptocurrency:

Crypto investing can be a bit complex, but it's not as scary as it seems. People invest in cryptocurrencies for the same reason anyone invests in anything: they hope its value will rise, netting them a profit.

Investors look for long-term bets based on the fundamentals of an investment, and cryptocurrencies can be viewed through a similar lens. You don't have to jump in with large amounts, either - you could start with as little as 15 dollars!

Fundamental analysis (FA) is a key concept in investing, and it's worth looking into. FA involves analyzing a company's or asset's financial health, management, and industry trends to determine its value.

Asset allocation and diversification are also crucial in investing, including crypto investing. This means spreading your investments across different assets to minimize risk and maximize returns.

Dollar-cost averaging (DCA) is another strategy to consider when investing in cryptocurrencies. This involves investing a fixed amount of money at regular intervals, regardless of the market's performance, to reduce the impact of volatility.

If you want to invest in cryptocurrencies, there are several ways to get started. You can start by learning about the fundamentals of an investment, such as FA, asset allocation, and DCA. You can also explore different types of cryptocurrencies, such as Bitcoin and Ethereum.

Here are some key concepts to consider when investing in cryptocurrencies:

Remember, investing in cryptocurrencies involves risk, and there are no guarantees of profit. However, with the right approach and a solid understanding of the fundamentals, you can make informed decisions and potentially reap the rewards.

Cryptocurrency exchanges can be a bit tricky, but essentially, they allow customers to trade cryptocurrencies for other assets, such as conventional fiat money, or to trade between different digital currencies.

It's worth noting that crypto marketplaces don't guarantee that an investor is completing a purchase or trade at the optimal price, which can lead to opportunities for arbitrage.

As of 2020, it was possible to arbitrage to find the difference in price across several markets, so it's essential to do your research and stay informed to make the most of your trades.

Crypto marketplaces provide a platform for trading, but they don't provide any guarantees about the prices.

Investors need to be aware of the risks involved and do their research before making any trades.

Crypto marketplaces are constantly evolving, and new exchanges are emerging all the time, offering different features and services.

ATMs are a convenient way to access your cryptocurrency, and they've been around since 20 February 2014, when Jordan Kelley launched the first bitcoin ATM in the United States.

The first bitcoin ATM was installed in Austin, Texas, and it's similar to a regular bank ATM, but with scanners to read government-issued identification to confirm users' identities.

This innovation made it possible for people to buy and sell bitcoins using cash, which was a major breakthrough in the world of cryptocurrency.

Cryptocurrencies are not clearly defined as securities, but regulators have signaled they should be regulated similarly to stocks and bonds. This could have major implications for the asset class.

The Supreme Court's June 2024 Loper Bright Enterprises v. Raimondo ruling may change how cryptocurrencies are regulated, potentially shifting the responsibility to Congress to clearly define crypto regulation through law.

The rise of cryptocurrencies has led to increased scrutiny from governments, with the Financial Action Task Force (FATF) defining cryptocurrency-related services as "virtual asset service providers" (VASPs) and recommending regulation to protect users.

In the US, the IRS ruled in 2014 that bitcoin will be treated as property for tax purposes, making it subject to capital gains tax.

The FATF's Travel Rule, updated in June 2020, mandates that VASPs obtain and exchange information about the originators and beneficiaries of virtual asset transfers.

The European Commission published a digital finance strategy in September 2020, including a draft regulation on Markets in Crypto-Assets (MiCA), which aims to provide a comprehensive regulatory framework for digital assets in the EU.

Regulators are taking a closer look at cryptocurrencies, defining them as "virtual asset service providers" (VASPs) to ensure they adhere to the same anti-money laundering (AML) and know your customer (KYC) requirements as financial institutions.

The Financial Action Task Force (FATF) has developed a universal common language, IVMS 101, for communication between VASPs, aiming to standardize data exchange.

In June 2020, the FATF updated its guidance to include the "Travel Rule" for cryptocurrencies, requiring VASPs to obtain and exchange information about originators and beneficiaries of virtual asset transfers.

This regulation is part of a broader effort to provide a comprehensive framework for digital assets in the EU, as seen in the European Commission's digital finance strategy published in September 2020.

The Basel Committee on Banking Supervision proposed that banks holding cryptocurrency assets must set aside capital to cover potential losses, a more extreme standard than for other assets.

The IMF is seeking a coordinated approach to supervising cryptocurrencies, emphasizing the need for global regulations to maintain financial stability.

In the United States, the IRS ruled on March 25, 2014, that bitcoin will be treated as property for tax purposes.

This means that virtual currencies are considered commodities subject to capital gains tax.

Banks have been making significant moves in the world of cryptocurrency, with some major institutions actively working on blockchain initiatives.

Morgan Stanley, the first big Wall Street bank to embrace cryptocurrencies, announced in 2021 that they would be offering access to bitcoin funds for their wealthy clients.

BNY Mellon, another major financial institution, followed suit by announcing that it would begin offering cryptocurrency services to its clients in February 2021.

Major financial institutions are taking the leap into cryptocurrency, and it's not just about investing - it's about offering new services to their clients.

Venmo, a popular digital payment platform, added support for buying, holding, and selling cryptocurrencies on its platform in April 2021.

Mastercard is also getting in on the action, working with digital asset manager Bakkt to create a platform that would allow any bank or merchant on the Mastercard network to offer cryptocurrency services, announced in October 2021.

These moves show that banks are serious about embracing cryptocurrency and offering new services to their clients, and it's likely that we'll see even more developments in this area in the future.

Bitcoin's social and political aspects are complex and multifaceted. Libertarians and anarcho-capitalists were attracted to the philosophical idea behind bitcoin, seeing it as a way to separate money from the state.

Roger Ver, an early bitcoin supporter, said that almost everyone who got involved did so for philosophical reasons. They believed in the idea of a decentralized currency that didn't rely on central authorities.

Economist Paul Krugman, however, views cryptocurrencies like bitcoin as "something of a cult" based in "paranoid fantasies" of government power. This contrast highlights the differing opinions on bitcoin's social and political implications.

The ideas influencing bitcoin advocates emerge from right-wing extremist movements such as the Liberty Lobby and the John Birch Society, which have anti-Central Bank rhetoric. This is also reflected in the views of Ron Paul and Tea Party-style libertarianism.

Steve Bannon, a bitcoin investor, sees cryptocurrency as a form of disruptive populism, taking control back from central authorities. This perspective highlights the potential for bitcoin to challenge traditional power structures.

Bitcoin's founder, Satoshi Nakamoto, supported the idea that cryptocurrencies go well with libertarianism. Nakamoto believed that "it's very attractive to the libertarian viewpoint if we can explain it properly."

The decentralization of money offered by bitcoin has its theoretical roots in the Austrian school of economics, especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined.

Cryptocurrencies offer several advantages, including removing single points of failure, making it easier to transfer funds between parties, and eliminating the need for third-party intermediaries. This can lead to faster and more secure transactions.

One of the most significant benefits of cryptocurrencies is their ability to streamline remittances, allowing people to send money across borders without the need for intermediaries. According to Pew Research Center data, 16% of Americans have invested in, traded, or used a cryptocurrency.

Here are some of the key advantages of cryptocurrencies:

On the other hand, cryptocurrencies also have some disadvantages, including the fact that transactions are pseudonymous, which can allow for criminal uses. Additionally, some cryptocurrencies have become highly centralized, making them vulnerable to security issues.

Cryptocurrencies offer several advantages, including the ability to remove single points of failure, making transactions easier and faster between parties, and eliminating the need for third-party intermediaries. This decentralized system can streamline remittances and provide a new way to generate returns.

One of the key benefits of cryptocurrency is its ability to remove central banks from managing the money supply, which can help prevent inflation. In communities that have been underserved by the traditional financial system, cryptocurrencies can provide a promising foothold.

Cryptocurrencies also offer a secure way to transfer funds, using public keys and private keys to secure transactions. This can be faster than standard money transfers, and can even be used for flash loans in decentralized finance, which can be executed within seconds.

Some cryptocurrencies also offer the opportunity to earn passive income through a process called staking, which involves using your cryptocurrencies to help verify transactions on a blockchain protocol.

Here are some of the key advantages of cryptocurrency:

And here are some of the key disadvantages:

Equality is a key aspect of the cryptocurrency world, where different coins and tokens have their own unique features and purposes.

Bitcoin, for example, is often referred to as the "king of cryptocurrencies" due to its widespread adoption and acceptance.

Ethereum, on the other hand, is a distributed computer that enables the creation of smart contracts and decentralized applications.

Monero is a coin that prioritizes privacy, making it a popular choice for those who value anonymity.

Here's a brief rundown of some of the most well-known cryptocurrencies:
