What is Cryptocurrency: A Beginners Guide

From digital art to sports collectibles to gaming if you want to start investing in non-fungible tokens here are the best marketplaces where you can buy and sell NFTs.

Cryptocurrency can also be called electronic money. They cannot be touched or held in hands, but they can be exchanged for quite ordinary money and perform other operations characteristic of various currencies: buy something with them and sell. Cryptocurrencies act not only as a means of payment but also as a way to invest – in recent months, cryptocurrencies have risen significantly in price, which makes them look at as a high-risk way to make good money. The biggest disadvantage of this kind of investment is that it is impossible to predict how much digital money will be worth tomorrow.

What is Cryptocurrency?

A cryptocurrency, also known as crypto-currency or crypto, is a collection of binary data used as a medium of exchange. Individual coin ownership records are kept in a ledger, which is a computerized database that uses strong cryptography to secure transaction records, control coin creation, and verify ownership transfers. Because cryptocurrency is not backed by or convertible into a commodity, it is classified as a fiat currency. Validators are used in some crypto schemes to keep the cryptocurrency running. In a proof-of-stake model, token owners put their tokens up as collateral. In exchange, they receive proportional control over the token based on their stake.Token stakers typically gain additional ownership in the token over time as a result of network fees, newly minted tokens, or other similar reward mechanisms.

Cryptocurrency is a system that satisfies the following six criteria: 


Fun Fact: The Merriam-Webster Dictionary added the term cryptocurrency to its dictionary in March of this year.

History of Cryptocurrencies

NFT marketplaces are platforms or, simply put, “NFT malls” where they can be sold, bought or exchanged. They are created specifically for non-exchangeable tokens and all kinds of digital works are stored, displayed, sold, and in some cases even created here.

There are many such resources available today, but we’ll focus on the 10 most popular and interesting ones. Let’s go!

History of Cryptocurrencies

The theoretical concept of cryptocurrencies existed long before their debut in virtual space. The first enthusiasts of the idea were excited about how the use of computer technology could solve the practical and political limitations that existed in the traditional fiat currencies segment. In the 1990s, there were many attempts to create a global digital currency, but they were all unsuccessful.

Finally, in 2008, a programmer (or group of programmers) under the alias “Satoshi Nakamoto” tried to create a digital monetary system without a central controlling authority. More actively about the new financial tool, as a new phenomenon, began to talk in 2009 – after the first popular cryptocurrency – bitcoin (BTC) was launched.

Data on capitalization, value, and other information about bitcoin you can find here at CoinMarketCap.

Bitcoin was the first digital asset that retained value when sent over the Internet without needing an intermediary or specialized third party to verify the transaction.

Since then, thousands of other crypto coins have been launched, including suspect projects – such as the cryptocurrency Prism. New versions of bitcoin continue to appear almost every month.

Many new cryptocurrencies have similar basic characteristics, but developers are tirelessly improving transaction procedures and creating new solutions to improve the existing system.

Cryptocurrency Rate

The rate of cryptocurrencies is not tied to oil or gold. The only factor that raises the price of, say, bitcoin is a limited issue and a rise or fall in demand: the number of bitcoins is limited. You could compare it to a mineral such as platinum – the amount of material in the world is limited, and it cannot be created artificially. This is the main advantage of cryptocurrency – the impossibility of counterfeiting.

However, financial experts keep telling about the riskiness of such investments, and many states still prohibit operations with cryptocurrencies in their official markets.

Several factors influence the price of a single bitcoin, including supply and demand, competition, and regulation. Investor perceptions of cryptocurrency are also influenced by recent news events.
The intrinsic value of one bitcoin can be calculated by calculating the average marginal cost of production of a bitcoin at any given time, based on the block reward, electricity price, mining hardware energy efficiency, and mining difficulty.

Bitcoin reached an all-time high of $68,790 on November 10, 2021.

How to mine cryptocurrency

Bitcoin mining is the process of creating new bitcoins; it’s also how the network confirms new transactions, and it’s an important part of the blockchain ledger’s maintenance and development. “Mining” is a process that involves using high-tech hardware to solve a difficult computational math problem. The first computer to solve the problem receives the next block of bitcoins, and the process continues.

Cryptocurrency mining is time-consuming, costly, and only profitable on rare occasions. Many cryptocurrency investors, on the other hand, are drawn to mining because miners are rewarded with crypto tokens in exchange for their efforts. This could be due to the fact that, like California gold prospectors in 1849, entrepreneurs regard mining as a divine gift. If you are technologically inclined, why not try it?

Early on in Bitcoin’s history, individuals may have been able to compete for blocks with a regular at-home personal computer, but this is no longer the case. This is due to the fact that the difficulty of mining Bitcoin varies over time.

To ensure the blockchain’s smooth operation and ability to process and verify transactions, the Bitcoin network aims to produce one block every 10 minutes or so. If one million mining rigs compete to solve the hash problem, they will almost certainly find a solution faster than ten mining rigs working on the same problem. As a result, Bitcoin evaluates and adjusts the difficulty of mining every 2,016 blocks, or roughly every two weeks. The rewards for Bitcoin mining are halved every four years. 1 When bitcoin was first mined in 2009, one block was worth 50 bitcoins. In 2012, this was reduced to 25 BTC.

In September 2021, the price of Bitcoin was around $45,000 per bitcoin, so completing a block would have netted you $281,250 (6.25 x 45,000). It may not appear to be a bad incentive to solve the complex hash problem described above.

Cryptocurrency Exchange

If you, by all means, want to get hold of a couple of bitcoins or at least etheriums, while trying to earn something, a direct way to the exchange. Cryptocurrency exchanges work by approximately the same principle as the usual exchanges. The key difference in these platforms is that while a person cannot get to a regular exchange without a broker, it is possible to trade on a cryptocurrency exchange without involving other people in the process. The other steps are similar: register, set up an account in a particular currency quoted on a particular exchange, and you can make transactions. The main thing to remember is that there are two types of cryptocurrency exchanges. On some cryptocurrencies are bought and sold for “real” money – dollars, euros, pounds And on others – for electronic money. The latter act as cryptocurrency exchangers, where bitcoins can be exchanged for etheriums (or other cryptocurrencies) at the current rate online and earn money (or go bankrupt) in the process.

Following an investigation by the Australian Securities and Investments Commission in 2004, three Australian-based digital currency exchange businesses voluntarily shut down (ASIC). The services offered, according to the ASIC, required an Australian Financial Services License, which the companies lacked.

The US Secret Service shut down Gold Age Inc., a New York state-based digital currency exchange company, in 2006 after it had been in operation since 2002.

From their apartments, business owners Arthur Budovsky and Vladimir Kats were charged with “operating an illegal digital currency exchange and money transmittal business,” transferring more than $30 million to digital currency accounts. Customers had to provide limited identification documentation and could send money to anyone in the world for a fee that could reach $100,000. In April 2007, the US government ordered E-Gold administration to lock/block 58 E-Gold accounts owned and used by The Bullion Exchange, AnyGoldNow, IceGold, GitGold, The Denver Gold Exchange, GoldPouch Express, 1MDC (a Digital Gold Currency based on e-gold), and others, forcing G&SR (owner of OmniPay) to liquidate the seized assets.

E-Gold was hit with four indictments a few weeks later.

WebMoney changed its rules in July 2008, affecting many exchanges.WebMoney exchanges for the most popular e-currencies like E-gold, Liberty Reserve, and others have been prohibited since then.
In July 2008, the directors of E-three gold agreed to a plea deal with prosecutors, pleading guilty to one count of money laundering conspiracy and one count of operating an unlicensed money transmitting business. In 2009, E-gold ceased operations.

Is Cryptocurrency Secure?

Cryptocurrencies are usually created using blockchain technology.The way transactions are recorded in “blocks” and time stamps is described by blockchain. It’s a convoluted technical process, but the end result is a secure digital registry of cryptocurrency transactions that hackers can’t access.

In addition, transactions require two-factor authentication.You might be asked to enter your username and password at the start of a transaction, for example. You may then be asked to enter an authentication code that is sent to your personal cell phone via text message.

All of these security measures do not mean that cryptocurrencies cannot be hacked. There have been cases where a few hacks have cost cryptocurrency startups too much. According to Investopedia, in 2018, attackers “bilked” Coincheck and BitGrail to the tune of $534 million and $195 million, respectively. These two security incidents were the largest of the past year.

What is the difference between cryptocurrencies and tokens?

At first glance, cryptocurrencies and tokens appear to be the same thing. Both are traded on exchanges and can move between blockchain addresses.
Cryptocurrencies are designed solely to serve as money, whether as a means of exchange, savings, or both. All coins are functionally interchangeable, meaning that one coin is worth as much as any other.

Bitcoin and other early cryptocurrencies were designed as currencies, but later blockchains strive to do more. Ethereum, for example, provides more than just currency functionality. It allows developers to run code (smart contracts) on a distributed network and create tokens for various decentralized applications.

Tokens can be used like cryptocurrencies, but they have more flexibility. You can mint millions of identical tokens or just a few, but with unique properties. They can serve as anything from digital receipts representing a stake in a company to loyalty points.

In a protocol that supports smart contracts, the base currency (used to pay for transactions or applications) is separate from the tokens themselves. The native currency of Ethereum, for example, is ETH, which is used to create and transfer tokens on the Ethereum network. The ERC-20 and ERC-721 standards are used to implement these tokens.

What is a cryptocurrency wallet?

Basically, a cryptocurrency wallet is something that contains your private keys. It can be in the form of a special device (hardware wallet ), an app on your computer or smartphone, or even a piece of paper.
A wallet is the interface that most users use to interact with the cryptocurrency network. Different types of wallets offer different types of functionality – obviously a paper wallet can’t sign transactions or display current prices in fiat currency.

For reasons of convenience, software wallets (e.g., Trust Wallet) are used for day-to-day payments. In terms of security, hardware wallets are virtually unmatched for hiding locked keys from prying eyes. Users typically use both types of wallets to store funds.

Cryptocurrency capitalization

The main flaw people have when it comes to cryptocurrencies is ignorance of the terms. Many people confuse capitalization with exchange rate, which is a gross mistake. Yes, cryptocurrency capitalization depends on the cryptocurrency rate, but it is not the same thing. Usually, the higher the rate rises, the faster the capitalization rises. However, some experts are of the opinion that it is simply impossible to establish the market value of any cryptocurrency using the available schemes, so the capitalization of cryptocurrencies is a controversial issue. Experts are skeptical about the disappearance of cryptocurrencies.

The most famous case is when bitcoin creators, working under the nickname “Satoshi Nakamoto”, disappeared a few years ago, taking a million bitcoins with them. There were also earlier information about “burned” cryptocurrencies on corrupted hardware. Of course, the system is safer now, the rise in the price of electronic money has forced users to take this issue more seriously, but the risks still remain.


The price of a coin is multiplied by the number of coins in circulation to determine its “market cap.” Bitcoin has historically dominated the total cryptocurrency market cap, accounting for at least 50% of the market cap value, with altcoins increasing and decreasing in market cap value in relation to Bitcoin. Bitcoin’s value is largely determined by speculation, as well as other technological limiting factors like block chain rewards, which are coded into Bitcoin’s architecture technology.

The cryptocurrency market cap follows a trend known as “halving,” in which block rewards from Bitcoin are halved due to technologically mandated limited factors instilled in Bitcoin, thereby limiting the supply of Bitcoin. The cryptocurrency market cap rises as the date approaches a halving (which has happened twice before in history), followed by a downtrend.
