Cryptocurrency, What Is It & What A Beginner Investor Needs To Know

Cryptocurrency is the latest opportunity to hit the investment world. It is also a new way of earning money and storing wealth. Like all new investment categories, many people have no clue how it actually works and what opportunities exist for investing in cryptocurrency. Let me help you understand this new industry before delving into it. We’ll cover a lot of what you need to know to understand crypto better and get started down the road to making successful investments.

What Is Cryptocurrency?

Cryptocurrencies are digital currencies that use encryption techniques to regulate the generation of units and verify the transfer of funds. They are not controlled by any bank or government, which means they cannot be debased like fiat currencies. They also allow users to send money anywhere in the world without needing a third-party financial institution.

Cryptocurrencies are generally considered to be decentralized digital currencies. However, if you think about it, Bitcoin is not actually decentralized as it’s maintained by a group of developers and miners who decide what codebase needs to be used for the coin’s development. So, in fact, the term “decentralized” may not even apply to Bitcoin at all.

A lot of people refer to cryptocurrencies as virtual currencies because they aren’t regulated by any government or central bank; however, this label doesn’t fully describe what cryptocurrencies are. In reality, cryptocurrencies are just another form of currency that can be used online but can also be used in person-to-person transactions as well when paying for goods and services.

Cryptocurrencies use cryptographic algorithms called hashes (also known as cryptographic hash functions) to create new units of currency while ensuring that all transactions remain secure and anonymous. There are numerous different types of cryptographic hash functions, with each having its own pros and cons.

Who Invented Cryptocurrency?

Satoshi Nakamoto is the name of an anonymous person who developed Bitcoin and introduced it to the world. His real identity has never been uncovered, but many people believe that he is actually a group of people who came together to create this digital currency.

Satoshi Nakamoto’s genuine identity has never been discovered. However, there have been many theories about who invented cryptocurrency and where he came from. Some people say that it was invented by an unknown Japanese man named Dorian Satoshi Nakamoto; others believe that it was created by an American man named Nick Szabo or Hal Finney (a cryptographer). Some even think that it was created by a group of people who worked together under one name, such as Neal King (a cryptographer) and Vladimir Oksman (an Estonian programmer).

When Did Cryptocurrency Start?

The first cryptocurrency, bitcoin, was created by an anonymous developer named Satoshi Nakamoto in 2008. It was a decentralized peer-to-peer payment platform that uses state-of-the-art cryptography to secure transactions between two parties. Bitcoin was the first successful cryptocurrency, but there have been many others since then.

The cryptocurrency market has grown exponentially in recent years. The total value of all cryptocurrencies at the time of writing this is now worth more than $1.03 trillion — and it’s growing over time.

Cryptographic hash functions

A cryptographic hash function, also known as a message digest function or one-way function, is an algorithm that takes an input and produces a fixed-length hash value that can be used for identification purposes. The same input should produce the same hash value every time it is run through the hashing algorithm.

Hash algorithms are essential for cryptography because they allow two parties who have no previous knowledge about each other to create and verify digital signatures, as well as to derive other values from messages such as checksums or random numbers. Hash functions are also used in forensics and security applications where they are used to validate data integrity by identifying any change made to the original document or file.

Examples of Hash functions

There are many different types of cryptographic hash functions. Some of these functions are designed for use in public-key encryption, some for password storage, and some for checksums.


SHA1 was designed by the National Security Agency (NSA) and published by NIST as a federal standard in 1995 (FIPS 180-1). SHA1 produces a 160-bit hash value (20 bytes). SHA1 is similar to MD5, but it offers improved security over MD5 because it requires more than twice as many steps to produce an output as MD5 while still producing a 20-byte output result.


The SHA-2 family of hash functions are the most widely used cryptographic hash functions and a common standard within the U.S. government. These functions produce a 160-bit output from a data stream that is at most 224 bits long (SHA-224). The SHA-2 functions were designed by NSA in order to improve on the original SHA-1 algorithm (which was also an NSA design). They are optimized for 64-bit processors with 64-byte cache lines, although they can be implemented on 32-bit processors as well.


The SHA-3 competition was held in 2012 to select a new hash function standard; Keccak was selected as the winner of this competition and has been endorsed by NIST as FIPS 202. It produces a 256-bit output from a data stream that is at most 448 bits long (SHA-3 256).


MD5 (Message-Digest Algorithm 5) – MD5 was designed by Professor Ronald Rivest as a response to concerns about the security of SHA-1. It produces a 128-bit hash value from any input message of any length, making it suitable for use with any type of file or document. However, because MD5 uses only 32 rounds of hashing processing and does not use keyed hashing like its predecessor, MD4, it has been found to be vulnerable to collision attacks if used for digital signatures or other applications that require high levels of security.

How Do Cryptocurrencies Work?

Unlike centralized electronic money and central banking systems, cryptocurrency uses decentralized control. The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.

This database is used to track transactions and verify balances. Each cryptocurrency has its own blockchain where all transactions take place. Transactions are added to blocks which are linked together, creating a chain of blocks known as the blockchain. A copy of this blockchain exists on every computer in the network so that it is always available for use by everyone who participates in its maintenance and upkeep (known as miners).

Who is a crypto miner?

Cryptocurrency miners are the people who are responsible for verifying and adding transactions to the blockchain. A transaction can only be verified by a miner if they have all the necessary information, including who sent the funds and how much was sent. Miners also have a copy of the blockchain, which keeps track of every single transaction that has ever been made. This is why they are so important; they keep everything running smoothly and securely.

Miners receive rewards in return for their work, usually in the form of newly created cryptocurrency coins. This means that when you mine cryptocurrency, you are actually helping to create new money.

Miners use special software to solve mathematical problems as part of their verification process. These problems require a lot of computing power to solve quickly – this is what gives miners more power over others when it comes to solving blocks faster than anyone else in order to earn more rewards from doing so (and hence increasing their profits).

How do miners verify transactions?

Miners verify transactions by solving a cryptographic puzzle that requires them to find a number whose hash value starts with several zeros. This number is called a nonce, and it’s an arbitrary number that increases the difficulty of finding an appropriate hash value for each block. Once they find it, they announce their solution to the network, which then verifies if it’s correct or not.

There are a few different ways you can use cryptocurrencies:

• Exchange it for fiat money like dollars or euros (or vice versa)

• Pay for goods and services with merchants who accept cryptocurrencies as payment (like Overstock.com)

• Sell it for bitcoins or other cryptocurrencies on an exchange site like Coinbase or Kraken (or vice versa)

What Is The Blockchain?

The blockchain is a digital ledger used to keep a record of cryptocurrency transactions. When a transaction takes place where crypto is transferred from one account or wallet to another, it is recorded in the blockchain as a public record of that transaction. It is constantly growing as “completed” blocks are added with a new set of recordings. Each record or “block” contains a cryptographic hash of the previous block, a timestamp, and transaction data. By example, Bitcoin is built on a blockchain that is used to record legitimate transactions and also to distinguish them from attempts to re-spend coins that have already been spent elsewhere.

The use of blockchains allows two parties who do not fully trust each other to interact without having to go through a trusted third party or central server. This means that a transaction can be completed between two parties without needing any kind of middleman or intermediary service providers, such as eBay or PayPal or a bank.

How does blockchain work?

A blockchain is a decentralized, distributed, and open digital ledger that is used to record transactions across many computers in such a way that the record cannot be changed retrospectively without affecting all subsequent blocks and requiring network collusion. This allows the participants to verify and trust the ledger in a trustless environment.

Blockchain technology was invented to support bitcoin, but it can be used for so much more than just cryptocurrency. The blockchain is an incorruptible digital database of economic transactions that can be configured to record nearly anything of value, not only financial transactions.

Blockchain technology can also be used to create a permanent, public, transparent ledger system for compiling data on sales, tracking digital use and purchases, checking for counterfeit goods, and even validating electronic voting results. In this way, it can help reduce fraud and errors that occur during manual data entry processes.

Why is the Blockchain so secure?

The blockchain’s ability to store data securely and transparently, without any need for central oversight, makes it an attractive option for secure record-keeping. Because it can be used to store any type of data, including money, contracts, and identity information, it offers an efficient way for people or companies to share information with each other securely — without having to rely on third parties such as banks or governments.

Here are some of the main ways in which blockchains provide security:

Immutability — Once there’s a record on the blockchain, it can’t be altered without being noticed by everyone else using the network. This makes it harder for hackers to tamper with data without being detected.

Durability — Blockchains are designed so that they can’t be hacked or compromised by outside forces because there’s no single point of failure. No one person or company controls the network; instead, users collectively manage it through consensus-based decision making. If hackers were somehow able to compromise the system, then that would only result in a minor delay and inconvenience for some users. The rest of the network would still be using the correct version of the ledger and would continue to operate as normal.

What Is The Difference Between A Crypto Coin And A Crypto Token?

Although the terms “crypto coin” and “crypto token” are frequently interchanged, they have distinct meanings.

What Is A Crypto Token?

A crypto token is also known as an ERC-20 token or a utility token because it provides access to certain products or services within its ecosystem. Unlike crypto coins, which are used for payments, tokens are used by investors who want to participate in an ICO (Initial Coin Offering).

What Is A Crypto Coin?

A crypto coin is a form of digital currency that can be used for transactions. It has no physical form and exists only in the digital world as numbers on your computer screen or smartphone.


A crypto coin is just like a regular coin: It represents value and can be used as payment. One example of a crypto coin is Bitcoin (BTC), which is one of the most popular cryptocurrencies in circulation today. The value of BTC fluctuates greatly depending on market conditions and sentiment regarding its future potential.

A crypto token is usually associated with some specific blockchain-based platform or project. A good example would be an Ethereum ERC20 token like OmiseGo (OMG).

What Is A Crypto Wallet?

A crypto wallet is a software program that stores public and private keys and interacts with various blockchains to enable users to send and receive digital currency and monitor their balance. Cryptocurrency wallets are software programs where you can store your digital money. They come in many different forms, designed for different types of devices and purposes. The most common type of cryptocurrency wallet is an online wallet, which allows users to access their funds from any location. Online wallets are cloud-based services, so they don’t need any additional hardware or installation on the user’s device.

If you want to own a cryptocurrency wallet but don’t have many technical skills, then you can use an online wallet provider like Coinbase or Coinomi (Android). They offer simple interfaces that make it easy for beginners to use them even if they don’t know much about cryptocurrencies yet. One of the biggest advantages of using an online wallet provider is that they allow users to exchange fiat currencies with cryptocurrencies easily as well as buy them from other people via bank transfers or credit cards.

What Are The Different Kinds Of Crypto Wallets?

Desktop wallets

These are downloaded from the internet and installed on your computer. They can be used with any device that has an internet connection (including mobiles). Desktop wallets do not store your keys on a website, so they are more secure than web-based wallets. However, they are more difficult to use than mobile or hardware wallets.

Mobile wallets

Mobile wallets run on your smartphone as an app and can be used in much the same way as desktop wallets. They allow you to send and receive bitcoins through Q.R. codes or NFC (Near Field Communication) if your phone has this feature installed. The advantage of using a mobile wallet is that the private keys never leave your device, so they cannot be stolen by hackers like desktop wallets can be. Most mobile wallets use servers that store data for their users, but there are some which allow you to keep control of your own private keys and therefore retain privacy over your transactions too.

Hot wallets

Hot wallets are online cryptocurrency wallets that allow you to access your coins immediately, anywhere in the world. Hot wallets are more convenient than cold storage because they don’t require any time to set up or any knowledge about how to use a command-line interface (CLI). However, this convenience comes at the cost of security since hot wallets are stored on an online server that can be hacked into by malicious actors.

Cold storage

Cold storage refers to storing your coins offline on a hardware device such as a USB drive or hard drive. Cold storage has its own advantages over hot storage because it’s much less vulnerable to hacks than an online wallet. However, it does have some disadvantages, too, because you won’t be able to access your money whenever you want unless you have another device with you that is connected to the internet (and therefore vulnerable).

Hardware wallets

Hardware wallets are small devices, often USB sticks, that store your private keys on a computer completely disconnected from the internet. They can be a bit cumbersome to use, as they require you to manually connect them to a computer when you want to send funds, but they are by far the most secure type of wallet.

Paper wallets

A paper wallet is simply a piece of paper with your public and private keys printed on it (whereas an electronic wallet stores your private keys electronically). All you need to do is write down your public address and private keys, keep them safe somewhere safe and then use that public address whenever you want to receive cryptocurrency in your wallet.

What Is Fiat Currency Vs. Cryptocurrency?

Fiat currency refers to the paper money and coins that are printed by the government and have value. The term comes from the Latin word “fiat,” meaning “let it be done.” Fiat currency is also known as hard currency because it can be used to pay for goods and services or exchanged for other currencies. Examples of fiat currencies include the U.S. Dollar (USD) and the Euro (EUR).

Cryptocurrency, on the other hand, is a digital currency that uses cryptography for security. It is also referred to as virtual currency or digital money. Examples of cryptocurrencies include Bitcoin (BTC), Ether (ETH), Litecoin (LTC), and Ripple (XRP). Unlike fiat currencies, cryptocurrencies do not have any legal tender status in any jurisdiction around the world.


Fiat currency has no intrinsic value, while cryptocurrency does

The value of fiat currency is determined by the government that issues it. The United States dollar, for example, is backed by the full faith and credit of the U.S. government. This means that if you have one dollar in your pocket, the government will accept it as payment for tax obligations and other debts.

The only way for a government to create more money is if it prints more paper bills or mints more coins — but this does not increase its value. The amount of circulating cash in an economy also has an impact on its inflation rate (how much prices increase). If there are too many bills in circulation, then more people will try to spend them before they lose their value due to inflation. This leads to higher demand for goods and services, which causes prices to rise quickly.

Cryptocurrency has value because it can be used as a medium of exchange — just like fiat currency — but it can also be used as a store of value or unit of account (measurement). Cryptocurrencies are not backed by any sovereign nation or authority but instead rely on cryptography and peer-to-peer networks to create trust between users who transact with each other online without having to trust middlemen such as banks or governments.

It’s easier to use fiat currency in everyday transactions, while cryptocurrency use is limited

Fiat currency has been around for centuries and is accepted worldwide as a form of payment. Cryptocurrency is not yet widely accepted in most places around the world, which means you cannot use it as easily as you can use fiat currency when traveling internationally or shopping online at home.

Where To Buy Cryptocurrency?

The question of where to buy cryptocurrency can be a bit tricky, as there are many options out there. The answer depends on your location, payment method, and preferred coin. If you are looking for Bitcoin (BTC), Ethereum (ETH), or Litecoin (LTC), Coinbase is one of the most popular places to purchase these cryptocurrencies.

You can register with Coinbase by providing your email address and phone number. To purchase cryptocurrency, you will need to provide further information about yourself, including your name, address, and credit card details. After this process is completed, you will receive a confirmation email from Coinbase and will be able to start buying coins instantly.

Alternatively, if you want to buy altcoins such as Ripple (XRP), Dash (DASH), or Monero (XMR), then Kraken would be a good option for you. This site offers a wide variety of coins and has some great features such as margin trading that allows you to make money on price movements in the market without having to own any coins yourself. You can use USD or EUR as your base currency when trading on Kraken, which makes it easy for Europeans who want to convert euros into crypto.

Binance – this is one of the largest cryptocurrency exchanges in the world, and it has over 200 different coins listed on its platform. The site offers both basic trading options as well as advanced ones such as margin trading.

What Is A Centralized Exchange Vs. Decentralized Exchange?

What Is A Centralized Exchange

A centralized exchange is a platform where a user can buy or sell cryptocurrency. It is owned by a single entity and managed through a central server. The exchange charges a fee for its services, which include verifying transactions and keeping track of users’ funds.

What Is A Decentralized Exchange?

A decentralized exchange is also known as a DEX. In this type of trading platform, there are no third parties involved in managing your funds or providing escrow services. Instead, trades are made directly between traders using their own respective wallets. There is no need to register with an account or provide personal information when using this type of platform.

How Many Cryptocurrencies Are There?

As of 2022, there are 18,465 cryptocurrencies. This number is expected to grow exponentially in the coming years as more people become aware of cryptocurrencies and their potential.

The main Cryptocurrencies include:

Bitcoin (BTC) is the most popular cryptocurrency which is used by many people. Bitcoin (BTC) offers anonymity and decentralization to its users. It also offers security to its users as it uses blockchain technology to keep all transactions safe and secured.

Ethereum (ETH) is another cryptocurrency that has gained popularity among many people because it allows developers to create decentralized applications (DApps), smart contracts, and even DAOs on its platform.

Ripple (XRP) is another popular cryptocurrency that allows banks and other financial institutions to make cross-border payments instantly and at low costs with minimal risks involved in the process.

Litecoin (LTC) was launched in 2011 as an alternative to Bitcoin due to some limitations found in Bitcoin, such as slow transaction speed and high transaction fees for miners. Litecoin also uses blockchain technology but differs from Bitcoin in terms of confirmation time, block generation rate, and maximum supply limit.

Dodge coin is a cryptocurrency that was launched in the year 2019. It was developed by dodgecoinfoundation, and it is based on the PoS algorithm. The total supply of this cryptocurrency is 100,000,000 DOGE. This cryptocurrency can be traded on major exchanges like Binance, Kucoin, and Cryptopia. These exchanges are located in different parts of the world, such as China and Hong Kong.

Cardano is a blockchain platform that was launched in 2015 by Charles Hoskinson and Jeremy Wood. The main aim of this project was to provide solutions to some of the problems that were facing Bitcoin, such as scalability issues and interoperability between currencies created by different developers. Cardano also provides a platform for decentralized applications (dApps) to be built on top of its network. The total supply of Cardano is 31 billion coins which are divided into two layers, namely Cardano Settlement Layer (CSL) and Cardano Computation Layer (CCL).

Is Investing In Crypto Risky?

The truth is that investing in crypto is risky, but it’s not as risky as it might seem. In fact, the riskiness of investing in crypto depends on a number of factors. The most important one is your level of experience with cryptocurrency.

If you’re new to crypto, then the risks are much higher than if you’re an experienced investor who has learned the ins and out of cryptocurrency. But even then, there are ways to mitigate those risks and make sure that you’re investing wisely for your own benefit.

What Are The Risks Of Investing In Cryptocurrency?

The most obvious risk of investing in cryptocurrency is the volatility of prices. The price of a cryptocurrency can swing wildly over short periods of time, making it difficult to determine an appropriate entry point into the market.

This leads many people to invest more than they can afford to lose, which can have devastating consequences if the price drops substantially before they’re able to sell their position.

Another risk is that governments around the world may decide that cryptocurrencies are too risky or unstable and ban them altogether. This could cause a major crash in prices.

There are also many smaller risks associated with investing in cryptocurrency, such as exchange security breaches, fraud and hacking attacks on exchanges and wallets, scams, lack of liquidity, and more.

As far as financial investment opportunities go, cryptocurrency can be a bit scary. It’s not something that is easily understood or readily accepted among the masses yet. However, it seems as if these fears are slowly dissipating as of late. In reality, even if you’re not too inclined to give this a try, this guide should have enough information to help you make an informed decision when investing in your money.
