Cryptocurrency is a decentralized digital currency that doesn’t belong to any single authority. It was created in 2009 by an anonymous developer or group of developers named Satoshi Nakamoto.
The entire process of transferring funds from one’s wallet to another person is called “mining”. It happens by solving complex mathematical equations that validate transactions on a blockchain network.
As soon as somebody solves the equation, they get a reward in the form of cryptocurrency. This reward can be exchanged for fiat money or other cryptocurrencies at any time. But before anything, let us learn what cryptocurrency is.
What is Cryptocurrency?
Cryptocurrency can be defined as a digital currency or medium of exchange. The best-known examples are Bitcoin, Litecoin, and Dogecoin. While Bitcoin is the most expensive cryptocurrency in the world, with a market cap of US $14 billion, Litecoin is a cheaper alternative to Bitcoin, with a market cap of US $1.8 billion.
Thinking about what makes cryptocurrency different from traditional currencies like USD? Cryptocurrency transactions are decentralized, so you don’t need to use banks or other third parties for transactions and transfers.
It is secure, fast, and private. Cryptocurrency transactions can be made anonymously. This means that no names are attached to the transactions, so the sender and receiver of funds remain anonymous.
They can also be made without paying transaction fees to move money around. The downside to this is trust -as in a DDoS attack against a website, it’s impossible to tell who initiated the attack and when it started.
Cryptocurrency transactions are often made using blockchain technology. Blockchain describes a network of computers all linked together with a common purpose – ensuring that all cryptocurrency transactions are legitimate and correct. A block in this system contains several cryptocurrency transactions on it.
How does cryptocurrency work?
Cryptocurrency has been around for quite some time — in the early days, people had tons of Bitcoin that they received as part of their mining process, which was arduous work to do back then because computers were far less potent than they are today.
Today, most cryptocurrencies are generated by making it easier to create a new block, and how you do this is slightly different for each cryptocurrency. This is commonly how it works:
The miners run software on their computers linked together on a network. When they solve a complex math problem, their computer gets to add the following block to the blockchain. They get rewarded in cryptocurrency for successfully doing this (mining).
That was an oversimplification, of course — these days, there are specialized mining rigs with large amounts of graphics processing units (GPUs) that are designed just for doing this work. In addition, all of these computers need to be kept cool; otherwise, they will overheat and become unusable.
So now we have a blockchain — a record of all the blocks that have already been added to the blockchain. When you add a new block, it links with all the blocks before it. Every block also has a timestamp that connects it to the previous blocks on the chain. Anyone can use this blockchain to verify that any new information is valid because every block has its unique hash code.
Most miners today maintain a copy of the blockchain in their computer’s hard drive because if they don’t keep up with their copy and make sure the hash code for each block is correct, their computer could become unusable and stop working quite literally overnight.
Types of Cryptocurrency
We’ll take a look at three major types of cryptocurrencies: Bitcoin, Ethereum, and Dogecoin. They all have advantages and disadvantages but are traded on significant exchanges. There are also alternative cryptocurrencies like Litecoin, Dash, and others. Let’s take a closer look at each one!
Bitcoin
Bitcoin is the oldest cryptocurrency, but it is also the most used. At the same time, its popularity is decreasing slightly due to new competitors threatening its position. It is currently the only exchange-traded currency traded on most exchanges by anyone in over 100 countries!
Bitcoin has already overtaken gold as the most valuable currency in terms of value per unit because Bitcoin was established back in 2009. It has over 16 million users worldwide, with over 2 million daily transactions. The price of 1 BTC varies between $3200 and $5100, averaging around $3900.
Ethereum
Ethereum was developed by Vitalik Buterin almost a year before Bitcoin was launched. It can run smart contracts and has become a popular cryptocurrency for developers and investors.
The price of Ethereum varies from $300 to $1000, with an average of around $500. It has over 20 million users and makes up 3.2% of the cryptocurrency market.
Dogecoin
Dogecoin was launched in 2013 and is one of the most notable cryptocurrencies based on its use by popular Internet communities. It is considered one of the more fun types of cryptocurrencies to trade with due to its association with humorous Internet memes about a dog named Doge.
Its price varies from $0.0015 to $0.01, with an average of around $0.0025, making it the cheapest type of cryptocurrency to trade with! Dogecoin has over 50 million users and makes up 0.
Ripple
Ripple is a unique cryptocurrency because banks use it to transfer money worldwide. It was launched in 2012 and has been the third-largest cryptocurrency ever since!
Ripple has over 100 million users and has an average price of $0.20. This makes it one of the most affordable coins for traders, with over $950 million in daily transactions.
Tether
Tether is not a cryptocurrency instead, it is a stablecoin since it is 100% backed by cash deposits. This means that all Tethers in circulation are backed by actual cash reserves and can be redeemed at any time.
It was created in 2015 to facilitate the trading of Bitcoin without the need for individual users to open Bitcoin exchanges. Tether has an average price of $0.98 and over 1 million users!
Properties Of Cryptocurrency
Irreversible
Transactions can’t be reversed or banned. A cryptocurrency is an inanimate object. It’s not alive, so it cannot experience pain, hunger, or pleasure. Not that it matters because currency doesn’t have a conscious thought either way.
Whereas living things can feel these emotions from time to time, a currency cannot go through these feelings in the same way we do as human beings. This means when a transaction occurs between two people using cryptocurrency.
This transaction is irreversible, and there will be no turning back, no matter how bad the situation becomes for one person involved in the deal.
Pseudonymous
Cryptocurrency is pseudonymous, meaning that users are not required to provide any personal information to use it. It is P2P which means that there is no centralized control over the currency, meaning a single entity cannot control it, and its value cannot be manipulated.
Unlike fiat currencies, it has a fixed supply where new money can be created out of thin air. It has an open-source code, meaning anyone can contribute to its development and access the code and all the underlying data.
Fast and global
The system has been engineered to be lightweight and efficient, with no single points of failure, ensuring that transactions are confirmed quickly. Cryptocurrency is Fast and global, which means that it is fast and can be accessed from anywhere in the world at any time.
It is not owned by any specific entity, meaning no single institution controls crypto. Cryptocurrency is a decentralized network, meaning no one central authority controls the currency.
Secure
Cryptocurrency can’t be forged or hacked, as cryptography is one of its core principles. Cryptocurrency is secure, meaning that your wallet’s private keys never leave in unencrypted form – they remain encrypted.
A company must offer a wallet service, and they can take care of the encryption details by themselves. It’s also decentralized, meaning no single entity controls it or can regulate what you do with your coins.
In addition, it offers enhanced privacy as any third party cannot track transactions, and it’s fast, so you don’t have to wait for long transaction times.
Permissionless
There needs to be no government or financial institution permission to use cryptocurrency, which means anyone can send cryptocurrency without asking for permission from banks or any other financial institution.
How To Buy Bitcoin And Other Cryptocurrency
If you want to buy cryptocurrency, here are just three steps that you need to follow:
Step 1: Choose A Platform.
There are many different platforms to buy cryptocurrency, and each forum has its pros and cons. The best place to start is with an exchange that offers the cheapest and fastest order execution time.
Cryptocurrencies are available at competitive rates, making them worth your time and money: never stop trading, so you always have the opportunity to make more money!
Step 2: Funding your account.
Once you have selected your desired platform, the next thing you need to do is to fund your account. You can do this by either making a deposit or a purchase.
If you are buying Bitcoin, then, first of all, you will have to transfer some money into your account. Once this transaction has been completed, then you can use the interface to buy Bitcoin for USD, etc
Step 3: Place an order.
Enter the amount of cryptocurrency that you want to buy and choose your desired currency pair. In most cases, you can select your currency pair based on the current exchange rate.
Once your order has been submitted, it will instantly be processed. However, there may be slight delays in the time taken for order execution as it’s an open order book.
Therefore, the price you buy and sell at does not necessarily need to coincide with that of other traders. You will receive payment instantly into your bitcoin wallet.
How to store cryptocurrency
Cryptocurrencies are devices of monetary value, but they can be digital, making them difficult to store. Wallets are the most popular way to store cryptocurrencies.
They allow people to effectively manage their digital currency by making it easy for them to send and receive funds from other wallets, spend coins, and observe holdings among other things.
Different types of wallets have additional requirements for security and usage that must be considered before an individual decides on a kind of wallet for their needs.
Hot wallets and cold wallets are two popular types of wallets. Hot wallets are accessed through the internet and are used by individuals who want to make cryptocurrency transactions. In contrast, cold wallets are not linked to the internet and require physical access.
You can also have an online wallet, which combines the security of a cold wallet with the convenience of a hot one. There are three main types of online wallets that you should be aware of:
- Hosted: A hosted wallet is a web-based wallet maintained by an organization independent of the user and offers its services to cryptocurrency owners. Hosted wallets are a form of online wallet which can store private keys on company servers and are managed by exchanges or other organizations.
- Semi-hosted: A semi-hosted wallet is the same as a hosted one in that the private keys are stored on a web server. However, it has better security than a fully hosted one because users hold the power to reset passwords if needed.
- Non-Hosted: Non-hosted wallets don’t require users to store their cryptocurrency with an outside service provider. Instead, they use peer-to-peer (P2P) technology to send and receive funds among multiple parties.
What can you buy with cryptocurrency?
The reason for the popularity of cryptocurrency is its decentralization. Transactions on the blockchain are verified or “secured” by miners all over the world. This means that transactions cannot be blocklisted or manipulated by any single party who decides to make a change to whatever they want.
Cryptocurrency is also not regulated by banks, governments, or other large organizations like corporations and governments, which makes it appealing to those who want to maintain their privacy and experience more financial autonomy. Cryptocurrency tokens can be spent with vendors mostly anywhere in the world.
Technology and e-commerce sites
With the growing popularity of cryptocurrency and its tokens, more and more vendors are beginning to accept it as a form of payment. Cryptocurrency is also becoming more popular with vendors because it’s a speedy, cost-effective way to take payments on a large scale.

Luxury goods
Purchasing luxury goods online with cryptocurrency is now a reality through several e-commerce platforms. These luxury goods include everything from clothing and jewelry to art and collectibles.
The common feature among all luxury goods bought with cryptocurrency is that they are generally high-priced but what makes them valuable varies widely since they are not sold for any practical use but rather for their status as luxury items and collector’s pieces.
Cars
Buying cars with Bitcoin and then reselling them for more money. This is because the price of Bitcoin and other cryptocurrencies can fluctuate depending on the number of users trading them over the exchange platforms.
When more users want to purchase goods and services with cryptocurrencies, the demand will automatically increase, and so will the prices of these cryptocurrencies because they promise value to their owners.
On the same note, when there is less demand and users want to purchase goods or services using these cryptocurrencies, you can expect that their value will decrease substantially.
Insurance
There are many different types of insurance policies. And while some may allow you to pay premiums in bitcoin, others won’t even consider it an option. It depends on the type of policy you choose.
When you buy an individual insurance policy, your money is funding whatever the details of that policy describe. This means you’re paying coverage premiums – not a bank account.
When you apply for individual insurance, your insurance company will ask you a bunch of questions about what kind of coverage you want and how much you want to pay each month. It’s all based on variables like where you live and how much money you make.
Cryptocurrency fraud and cryptocurrency scams
The popularity of cryptocurrency has made it a target for online fraudsters and thieves. Cryptocurrency scams can be challenging to detect and even harder to avoid. This blog post will help you stay safe by teaching you how to protect yourself from the most common types of cryptocurrency fraud.

Is cryptocurrency safe?
Undoubtedly, cryptocurrency has been on the rise over the past few years, and with it comes a lot of risk on the market. To help you understand these risks, here’s an overview of different types of risk in cryptocurrency.
User Risk
In most cases, this type of risk is due to people not sufficiently knowledgeable about how trading works in cryptocurrency markets.
For example, buying bitcoin or another crypto asset without following proper procedures or understanding as they should have beforehand could give them emotional and financial losses.
Regulatory Risk
This risk is linked to exchanges and cryptocurrencies but is not directly related to the technology. It comes from external laws and rules that could affect your transactions. For instance, cryptocurrency transactions are still not regulated in most countries.
If they were, they could be considered illegal, which means you could lose all the money you invested if you cannot explain where your funds came from.
In addition to this risk, if your country decides to impose taxes on cryptocurrency transactions or exchanges. It might affect how you use cryptocurrencies, resulting in losses for you.
Counterparty Risk
This is the risk that a counterparty will not meet its obligation. For example, if you buy Bitcoin from another person who promises to send it to you soon, they keep delaying, and you start losing your patience. That’s between you and the counterparty.
Management Risk
This type of risk is usually related to big corporations with bad management skills but can also be a risk for individuals in smaller operations. For example, an exchange may have technical problems that make the website inaccessible when a new client wants to trade.
Programming Risk
This risk is related to software bugs in the applications and not security risks like hacking or phishing attacks that can lead to financial losses for traders.
Market Manipulation
This risk comes from other parties who want to manipulate the cryptocurrency market and make more money. For example, if a person or group tries to use the price of bitcoin by spreading rumors that a famous person died during a flight they were traveling—which is false—the market crashes with this news.
