Introduction

What Is Cryptocurrency

Cryptocurrency is a digital or virtual currency exchanged for goods and services, just like the more common fiat money. But there are some key differences. Cryptocurrencies use cryptography to secure and verify transactions on a distributed public ledger using open-source code. This means that anyone holding the cryptocurrency has access to it in its original form.

History

The first cryptocurrency was bitcoin, established in 2009 by an anonymous programmer as an open-source code project on GitHub. Today there are many other cryptocurrencies such as Ethereum, Litecoin, Dash, etc., with varying degrees of popularity and complexity in design; they are often collectively referred to as altcoins.

The concept of cryptocurrency emerged at the beginning of 2009 when an anonymous creator known as Satoshi Nakamoto published a Bitcoin paper: A Peer-to-Peer Electronic Cash System project website, GitHub. The idea was to create a currency independent from any central authority, transferable electronically, more or less instantly, with meager transaction fees.

By the end of 2010, bitcoin was trading at less than $0.01 per coin on an online exchange market. By the end of 2011, bitcoin reached $1 per coin. In November 2013, it crossed the $1000 threshold per coin, which gave rise to serious concerns regarding its safety in light of recent developments on Mt Gox exchange where thousands of bitcoins were stolen by hackers.

The value of 3,000 bitcoins that Mt Gox lost is now valued at $30 million. In the third week of 2013, another essential bitcoin exchange called Bitstamp suspended operations due to what appeared to be a technical issue. Later investigations by investigative journalists revealed that Bitstamp had suffered a security breach and hackers had stolen more than $5 million worth of bitcoins from their hot wallets.

In the fourth quarter of 2013, another major bitcoin exchange called Mt Gox filed for bankruptcy when it suspended its service, citing a DDoS (Distributed Denial of Service) attack on its computer systems triggered by unknown hackers. This led to over $473 million worth of bitcoins being lost and sent ripples throughout the bitcoin community.

To this day, bitcoin has experienced several significant price fluctuations, rising from less than $0.01 to $20,000. In 2013 it was the fastest-growing currency in the world. It is well on its way to becoming a global payment method for many businesses and individuals in the 21st century.

How Cryptocurrency Works

Bitcoin's initial function was a cryptocurrency, but it has evolved into something much more significant (see What Bitcoin is?). It is not just a currency for payments or online purchases but also serves as an electronic platform for storing wealth like gold and silver in conventional banking systems with little or no risk of theft due to digitalization and encryption technologies used by bitcoin.

Cryptocurrencies are designed to be completely decentralized, with a limited number of nodes or servers that can process transactions. They are mined by solving a set of complex algorithms, usually using hardware as powerful as graphics cards or processors and then stored in an encrypted digital wallet. Blockchain technology (see What Blockchain Technology is?) used in the cryptocurrency system enables users to access their digital currency from any location in the world without maintaining a physical wallet.

The blockchain is a public ledger where all cryptocurrency transactions are stored. The wallet owner can access it via their private key, which acts as an identifier and password. The private key is used to sign transactions and authorize withdrawals from the account, verified by network nodes.

The transaction details are then added to the blockchain by nodes that have verified the sender of the payment and were accepted by majority consensus. The cryptocurrency then moves between wallets. As time goes on and more people use a cryptocurrency, its value grows by demand and supply factors. This is similar to how gold and silver rose in value when demand rises and supply falls.

Advantages and Disadvantages

As the world becomes increasingly digital, many are turning to virtual currencies. There are many advantages to using cryptocurrency: no exchange rate hassles, you can carry a wallet on your phone so that you can spend money anywhere, and it also presents more security. However, there are disadvantages as well: some retailers refuse to take cryptocurrencies for transactions; also, some governments have instituted heavy regulations on them for use in the country of origin.

Types

Other cryptocurrencies have been developed over time based on bitcoin's underlying technology (see What Blockchain Technology is?). They include Litecoin, Ethereum, and Ripple. Each of these coins is competing with bitcoin to become the most popular cryptocurrency worldwide.

Introduction to Bitcoin

Bitcoin is a form of digital money or currency held in cyberdeposits without any physical embodiment like banknotes or coins. It is difficult to counterfeit and can be sent electronically from one person to another without the need for a central authority or any middle man. It is not controlled by a central bank like gold, government bonds, or other forms of money. Nor is it backed by any government or bank.

History of Bitcoins

It was established in 2009 by an anonymous programmer as an anonymous open-source project on GitHub with the alias Satoshi Nakamoto. The original project name was Bitcoin: A Peer-to-Peer Electronic Cash System. Still, this name has been abandoned as per the recommendations of a working group that includes core developers and Bitcoin Foundation representatives, suggesting that the bitcoin protocol should no longer be considered a peer-to-peer system.

The primary cryptocurrency has emerged as a new asset class in international finance with a market capitalization of over $200 million when writing this book. Bitcoin's price has experienced a meteoric rise from less than $0.01 in 2010 to over $20,000 by mid-2018

Why Trade Bitcoins

Bitcoin benefits its users by offering them a wide range of applications such as peer-to-peer payments, source of funds, investment assets, and a hedge against traditional market volatility. By design, bitcoin's blockchain technology cannot be controlled by any single authority. Its independence from central regulators also means that it is not subject to government regulations such as taxation, but this also makes it vulnerable to theft and fraud without regulation or protection by the authorities. This has made bitcoin somewhat volatile, with wild price swings representing a significant risk for investors or traders of cryptocurrencies.

Bitcoin is a digital currency at its most superficial level, but it can also be seen as the first global currency for the internet age. It offers excellent value for money, easy transferability, and various applications. It can be used to pay for purchases online, as an investment asset class, and hedge against traditional market volatility by converting it to fiat currencies like the US dollar or British pound.

About Other Cryptocurrencies

The Bitcoin protocol handles two functions: first, verify and record transactions made with bitcoins, and second, to create new bitcoins in each transaction. New bitcoins get created when network nodes compete to solve complex computer algorithms for which the winner gets rewarded with bitcoins. The reward gets divided among all the nodes that participated in the verification process.

Bitcoin is a decentralized currency, and network nodes verify its transactions without any central verification. It is a peer-to-peer network that operates without any single point of failure. All it requires is an internet connection, which could be either cellular or Wi-Fi.

The system was designed to operate in two ways: as a cryptocurrency and as a wallet for storing wealth with the expectation that its value would increase over time. Cryptocurrencies like bitcoin are designed to be used as an electronic payment system, not just as an investment asset class.

Learning the Lingo

Bitcoin has been around for ten years, but not many people know the bitcoin lingo.

What Is a Bitcoin Wallet?

A bitcoin wallet is where you store your bitcoins once you have exchanged them for Norwegian kroner or another currency. There are several types of wallets, each with different levels of security and functionality:

Online web-based wallets (third parties host these).

Mobile apps (these are downloadable apps that provide access to the private keys).

Hardware wallets (these are small devices that plug into your computer's USB port and enable you to spend bitcoins without internet access).

Paper wallets (these are pieces of paper with the address and private key printed on them).

Is it safe?

All wallet types listed above can be stored online or offline. When you store bitcoins offline, in a hardware or paper wallet, they are cold—not connected to the internet. You can also store bitcoins offline in a mobile app, but the app would have to be downloaded from an online app provider and configured offline using an air gap to protect your privacy.

Where Can I Get a Bitcoin Wallet?

You can get a bitcoin wallet from an online service provider, such as Coinbase. Or, you can download the original Bitcoin client (available for free on Bitcoin.org) and create a wallet on your computer.

Each wallet provider will give you a public Bitcoin address—this is the address others will use to send Bitcoins to you. If someone sends Bitcoins to your address, they are stored in your account until you are ready to spend them or exchange them for another currency.

Suppose you choose an online service provider (like Coinbase). In that case, it is a good idea to immediately move your coins into a mobile or hardware wallet that only you control after receiving them.

How Do I Get Bitcoins?

There are three basic ways to obtain bitcoins:

Buy them through an online service provider.

Mine them using your own computer's processing power.

Exchange them for cash or another cryptocurrency, such as Ethereum.

Bitcoin mining is the process of using your computer's processing power to help facilitate and verify transactions on the blockchain—a shared public ledger of transactions that everyone can access but no single person controls or owns. You are rewarded with bitcoins only if you provide this service (called hashing) efficiently, and on time, so it makes sense to join a mining pool for greater efficiency.

What Are Bitcoin Mining Pools?

A mining pool is a group of miners who combine resources such as processing power, advanced hardware, and computers with the most effective bitcoin mining software installed. You can participate by joining a mining pool with others. If you share your resources, you will earn proportionally more bitcoins per block solved.

Who Are the Most Significant Bitcoin Miners?

Bitcoins have not been mined in large quantities yet; the largest miner is:

Bitcoin miner Antpool—If Antpool breaks the current BTC/USD rate daily, it was enough to justify itself as one of the world's biggest Bitcoin mines for as long as it takes to settle this business.

Chapter 1. Comprehending Cryptocurrency Market Cycles

Let's imagine we bought some coins that we don't know anything about based on simple technical analysis for $10, and we find ourselves 24 hours later with the same coins, which dropped to $8. How would we manage the loss? What would happen is that the doubt of having invested in a dying, useless project or on the usual inevitable package would become an exhausting worm that would push us to sell; perhaps in the middle of a dump, perhaps at the lowest possible price (with the greatest possible damage.) It happens more frequently than you might imagine.

On the other hand, if we had bought some coins that we know well, having analyzed in detail the project on which we invested our money, then enduring a collapse from $10 to $8 becomes more accessible. However good a trader can be in technical analysis, it becomes challenging to trade cryptocurrencies without fundamental analysis. We have already had the opportunity to explain that fundamental analysis can be understood as collecting information by reading the company's financial statements in the stock market. Still, it is a pity that when we talk about cryptocurrencies most of the time, there is no company at all, let alone a budget.

However, there are factors that we can take into consideration, such as market capitalization (market cap.) By capitalizing on a cryptocurrency, we mean the total amount we obtain by multiplying the number of coins in circulation by the value of those coins. Another evaluation that we must make in this sense is to distinguish the maximum supply (21 million coins, for example, if we are talking about BTC) from that available (circulating.) Today, there are about 17,5 million BTC in circulation, compared to a maximum number of coins that will ever end up on the market equal to 21 million.

The quantity of coins in circulation, with the maximum number of coins that the network has budgeted, is one factor to study for a new cryptocurrency. For an accurate fundamental analysis, we should be able to disassemble the code of the open-source platform and understand how it is made, how it works, and above all, if it is well done. Not many people have the skills to do an accurate fundamental analysis of a blockchain project, who knows how to disassemble the platform and understand how it works. Ordinary people, who do not have excellent computer skills, therefore have other ways to try to understand if we can trust or not.

The very first things that every cryptocurrency trader wants to know when investing his money are about the community (the nodes and users in the network) and the identity of
