What is Bitcoin?
Bitcoin is a cryptocurrency that operates as a peer-to-peer payment system. The word "Bitcoin" is derived from two syllables: "bit," which refers to a binary unit of information composed of 0s and 1s, and "coin," which represents a form of currency. It was invented by Satoshi Nakamoto in 2008 and released as open-source software in 2009. Bitcoin's unit of account is the bitcoin, which is limited to 21 million units and can be divided up to the eighth decimal place. The smallest unit of Bitcoin is called a Satoshi, and it is equal to 0.00000001 BTC.
New bitcoins are created and distributed to individuals who secure the network. All transactions are verified by network nodes and recorded in a public and tamper-resistant ledger called the "blockchain." Anyone can access this ledger and see that address A sent BTC to address B.
The Bitcoin system operates without a central authority or a single administrator. Instead, it functions in a decentralized manner through the consensus of all network nodes. As a result, it is impossible to prevent someone from making a transaction, but it is also impossible to reverse a transaction. No one controls Bitcoin, and no one can decide to reverse transactions unless more than half of the network's computing power agrees to do so.
Bitcoin is the largest decentralized cryptocurrency, with a market capitalization exceeding $1 trillion as of March 2021. To send bitcoins, you need to possess your private keys, which serve as proof of your ownership and authorize the transaction. When you store your bitcoins on platforms, they hold your private keys, meaning you do not have complete ownership of your BTC. To truly own your bitcoins, you must be the sole possessor of your virtual keys. Wallets, also known as wallets, allow you to store your private keys so that you can check your BTC balance. Various types of wallets exist, with the most secure ones being those that do not have access to your keys. This way, you are the only person who can control and use your BTC.
Since its creation in 2009 and up until the closure of Silk Road by US authorities in 2013, Bitcoin was predominantly used as a medium of exchange by criminal networks. It was utilized for online gambling, purchasing illicit substances, and acquiring pirated databases. However, in recent years, the cryptocurrency has matured, and a growing number of studies conclude that these illegal activities, while still present as in any payment system, represent only a minority portion of overall Bitcoin transactions. Since the end of 2020, many companies have been publicizing their purchases or future use of this cryptocurrency. It started with MicroStrategy investing $250 million in August 2020, followed by PayPal in October 2020, announcing that it would enable users to acquire Bitcoin through their platform. Tesla also announced an investment of nearly $1.5 billion in February 2021. The expansive monetary policies of central banks in many countries could be a contributing factor to this trend.
What is Bitcoin?
Bitcoin (a word that can be divided into two syllables: "bit," which refers to a binary unit of information composed of 0s and 1s, and "coin," which represents a form of currency) is a cryptocurrency that serves as a peer-to-peer payment system. It was invented by Satoshi Nakamoto in 2008 and released as open-source software in 2009. Bitcoin operates without a central authority or a single administrator, functioning instead in a decentralized manner through the consensus of all network nodes.
How does the Bitcoin network work?
Transactions are conducted between different individuals, with bitcoins being sent from one address (address A) to another (address B), similar to bank account numbers. The most recent transactions are grouped together every 10 minutes into blocks, which are then broadcasted to all the network nodes. These nodes maintain the history of blocks and transactions.
All nodes collect these new transactions, and miners, nodes that provide proof of work by solving a mathematical problem, attempt to validate their blocks and earn a reward. Once a node finds the solution to the mathematical problem, it broadcasts its block to all the other nodes in the network. The other nodes verify that the transactions included in the block match those they initially received, ensuring that the validating node does not cheat.
If the majority of nodes accept the block, a new block is created, with a hash (a unique identifier) of the previous block included. The blocks are linked together like a chain, hence the term "blockchain."
Where can you buy Bitcoin?
You can acquire Bitcoin (BTC/XBT) in several ways:
On an exchange: a cryptocurrency exchange platform where you can buy Bitcoin through bank transfers, credit cards, or other available options.
In a physical currency exchange or automated teller machine (ATM).
On an online marketplace like LocalBitcoins.
Through classified ads and arranging a physical exchange.
Whether it is worthwhile to invest in Bitcoin depends on your risk appetite and the length of time you plan to hold your bitcoins. Individuals who hold onto their bitcoins for several years tend to see positive returns, but past performance does not guarantee future results. Before investing, it is advisable to educate yourself about how Bitcoin works and to avoid investing money that you cannot afford to lose. Start with small investments and have a thirst for learning, as even if you don't make money, you can gain valuable knowledge about finance, economics, and computer science.
Advantages and limitations of Bitcoin (BTC)
Advantages:
- The most famous cryptocurrency.
- Near-instant transfers, typically taking less than ten minutes, with low fees.
- Global reach for transactions.
- Lower payment fees compared to credit cards or PayPal.
- No limit on transferred amounts.
- No intermediaries required for storing or transferring bitcoins.
- Anyone can participate in bitcoin exchanges.
- Transactions provide pseudonymity.
- 9-Security:
Bitcoin utilizes advanced cryptographic algorithms to secure transactions. Each transaction is verified and permanently recorded on the blockchain, making data manipulation nearly impossible. Additionally, the Bitcoin network operates on a proof-of-work consensus mechanism, where miners solve complex mathematical problems to validate transactions, making the system resistant to malicious attacks.
Relative Anonymity: While Bitcoin transactions are transparently recorded on the blockchain, users can choose to remain relatively anonymous. Bitcoin addresses are not directly linked to users' real identities, providing a certain level of privacy during transactions.
10-Reduced Transaction Fees:
Transaction fees for Bitcoin payments are generally lower compared to traditional payment methods such as credit cards. This is due to the absence of intermediaries and the peer-to-peer nature of the Bitcoin network.
11-Global Accessibility:
Bitcoin is accessible to anyone with an internet connection, regardless of their geographical location. This enables fast and low-cost cross-border transactions, without the constraints and fees associated with traditional payment systems.
12-Scarcity and Protection against Inflation:
Bitcoin is designed to be limited to a total of 21 million bitcoins. This supply limitation creates a form of digital scarcity and provides protection against inflation, as the creation of new bitcoins is predetermined and reduced by approximately half every four years in a process known as "halving."
13-Potential Value Appreciation:
Over the years, Bitcoin has experienced significant growth in value. However, it's important to note that the price of Bitcoin is highly volatile and can fluctuate significantly over short periods. Investors should be aware of this risk factor when considering investing in Bitcoin.
14-Innovation Potential:
In addition to being a form of digital currency, the underlying technology of Bitcoin, blockchain, offers innovation possibilities in various fields such as finance, logistics, governance, and more. Many companies and institutions are exploring blockchain use cases to enhance efficiency and transparency in their operations.
Limitations:
- Disagreements among miners can create instabilities.
- Bitcoin has drawn scrutiny from certain governments.
- Other cryptocurrencies with improved technologies could potentially replace Bitcoin, which can be slow to adapt.
- Governments can enact laws to prohibit the conversion of fiat (traditional) currency into Bitcoin.
- There can be no more than 21 million units of bitcoin in circulation (as stated in the Bitcoin code).
- A unit of Bitcoin is divisible up to the eighth decimal place.
- 0.00000001 Bitcoin corresponds to 1 Satoshi.
- It is entirely possible to buy or sell fractions of bitcoins.
- Transactions are secure. As the number of users increases, transactions become more secure. I will explain the reason behind this in the following part of this chapter.
Blockchain: The blockchain is the underlying technology that enables the functioning of Bitcoin. It is a decentralized public ledger that records all Bitcoin transactions. Each transaction is grouped into blocks, which are then added to the blockchain in a chronological and immutable manner. The blockchain ensures transparency and integrity of Bitcoin transactions.
Mining: Mining is the process by which new bitcoins are created and transactions are verified. Miners are participants in the Bitcoin network who use their computational power to solve complex mathematical problems and add new blocks to the blockchain. In reward for their efforts, miners receive a quantity of newly created bitcoins as well as transaction fees.
Bitcoin Wallets: A Bitcoin wallet is software or a physical device that allows users to store, manage, and transact with their bitcoins. Wallets can be online (web-based), offline (offline storage), software-based (applications), or hardware-based (specific physical devices). Each wallet has a unique address associated with it, enabling users to receive bitcoins.
Price Volatility: The price of bitcoin is known to be highly volatile. It can experience significant fluctuations due to various factors such as market demand, institutional investor adoption, government regulations, public perception, and economic news. It is important to note that investments in Bitcoin carry a high level of risk due to this volatility.
Relative Anonymity: While Bitcoin is often considered anonymous, it is more accurately described as pseudonymous. All Bitcoin transactions are recorded publicly on the blockchain, meaning that Bitcoin addresses and transferred amounts are visible to everyone. However, users can choose not to reveal their real-world identity associated with their Bitcoin address. This provides a certain level of anonymity, but it is important to note that all transactions remain visible on the blockchain.
It's important to note that while Bitcoin has several advantages, there are also challenges and limitations to consider. Price volatility, evolving government regulations, and environmental concerns related to the massive energy consumption of the Bitcoin network are some of the aspects to consider before engaging in the use or investment in Bitcoin.
Bitcoin and the 2008 Financial Crisis
A New Solution in Uncertain Times
The 2008 financial crisis was a pivotal event that reshaped the global economy and had far-reaching consequences. It was during this tumultuous period that Bitcoin, the groundbreaking cryptocurrency, emerged as a potential solution to the flaws exposed by the crisis. In this article, we will explore how the crisis motivated individuals like Jeff and others to create a new form of currency and delve into how Bitcoin addresses certain problems associated with traditional fiat currencies. We will also discuss the potential risks associated with this innovative technology and shed light on the future prospects of Bitcoin.
The 2008 financial crisis played a crucial role in motivating the creation of Bitcoin a decentralized, transparent, and limited cryptocurrency that aimed to address flaws in traditional fiat currencies. While Bitcoin offers potential solutions, it is important for individuals to approach the cryptocurrency market with caution, given its volatility and regulatory uncertainties. The future of Bitcoin holds promise, but it is essential to stay informed and adapt to the evolving landscape of digital currencies.
Join me on a journey through history as we explore the fascinating origins of Bitcoin
This revolutionary digital currency wasn't created overnight—it emerged from years of dedication and collaboration. By understanding its roots, motivations, and potential, we can gain a clearer vision of this remarkable technology.
Let's start by acknowledging that before the 1970s, cryptography was primarily confined to military and intelligence agencies. It was a domain shrouded in mystery for most people. However, over time, cryptography gradually entered the public sphere with the release of various publications, leading to a certain level of democratization.
But what exactly is cryptography?
According to Wikipedia, it encompasses a set of processes aimed at encrypting information to ensure confidentiality between the sender and the recipient.
In 1992, a small group of cryptography enthusiasts began to gather in San Francisco. With a touch of humor, they dubbed themselves the "cypherpunks," cleverly combining "cypher" (encryption) and "cyberpunk," a subgenre of science fiction. Think of movies like the Matrix trilogy, which fall under the cyberpunk genre. In essence, the term "cypherpunks" can be translated as "crypto-anarchists."
This tight-knit group rapidly evolved into a global mailing list with over 700 members. Their discussions expanded beyond cryptography, encompassing mathematics, politics, philosophy, and computer science. They were driven by a shared passion for privacy, individual liberties, and the potential of decentralized technologies.
It was within this vibrant community that the idea of a digital currency, free from the control of central authorities, began to take shape. These forward-thinking individuals believed that cryptography could enable secure and private transactions, empowering individuals to take control of their financial lives.
Fast forward to 2008, and the world was shaken by the devastating financial crisis. Trust in traditional banking systems and centralized authorities was shattered. It was against this backdrop of economic turmoil and disillusionment that an anonymous figure, known as Satoshi Nakamoto, published a whitepaper outlining a groundbreaking concept the Bitcoin protocol.
Bitcoin, born from the ideas and ideals of the cypherpunks, aimed to create a decentralized, transparent, and secure digital currency. It harnessed the power of blockchain technology a distributed ledger that records all transactions immutably. This innovative system brought about the potential for financial autonomy, bypassing intermediaries and offering a new way of conducting transactions.
Since its inception, Bitcoin has come a long way. It has faced challenges, skeptics, and regulatory hurdles. However, it has also gained traction, attracting a growing community of users, investors, and innovators. Its potential to reshape finance, foster financial inclusion, and provide an alternative to traditional monetary systems is remarkable.
As we navigate the ever-evolving landscape of digital currencies, let's keep an open mind and explore the possibilities together. The future of Bitcoin and blockchain technology holds immense promise, and by staying informed and engaged, we can be part of this transformative journey.
Join me as we delve deeper into the world of Bitcoin, unravel its intricacies, and uncover the potential it holds for a more decentralized and inclusive financial future. Together, we can navigate the exciting realm of cryptocurrencies and embrace the opportunities they present.

Currencies and Banks
Bitcoin is a digital currency, a cryptographic currency, a peer-to-peer payment system... In other words, it is a currency that can only be used on a computer network. Bitcoin is not tangible, there are no physical bitcoin coins, for example. But before we delve into cryptocurrencies, let's first take a look at banks and the currencies we use in our daily lives (such as euros, dollars...).
I would like to start this chapter by sharing a fact: banks hold less than 10% of their customers' money. That means if you have around €5,000 in your bank account, the bank holds approximately €500 in coins and banknotes as a counterpart. But why is that? In reality, the money you deposit in the bank takes the form of a debt that the bank owes you. This debt, which used to be written on paper, is now stored in computer databases. So, in reality, if 90% of your capital is stored on a computer network, we can more or less consider your money as virtual money. It is indeed real, but you don't physically possess it in the form of coins and banknotes. And the same goes for Bitcoin—it is also real, but you don't own physical coins or banknotes; it is virtual. Virtual, yet real. Before we continue, it is essential to distinguish between two types of currencies:
Fiat currency: coins and banknotes.
Scriptural currency: the balance displayed in your bank account, which represents the debt the bank owes you.
Individuals typically store a significant portion of their capital in their bank accounts. In reality, the deposited money corresponds to just a few lines of code on a computer, and the bank doesn't store the equivalent of your deposit in banknotes in a vault... You see "+€1,000" on your online bank account, and you think you have €1,000. But that's not accurate! This "€1,000" is just a line in a database within the bank's computer system. In reality, the bank doesn't keep those €1,000 as banknotes, safely stored in a vault exclusively for you. It is simply a debt that the bank owes you.
And this can be problematic if we experience a monetary crisis. We recently witnessed the consequences of this in Greece. The entire population rushed to ATMs, causing the banks to run out of banknotes and be unable to meet the demands of their customers. This brings us to the topic of context. In what context and framework was Bitcoin born in 2008?
It's all about context
As mentioned earlier, crypto-anarchists are the originators of Bitcoin. It is important to note that in the 1990s and 2000s, several predecessors of Bitcoin emerged. The most well-known ones are:
B-money, envisioned by Wei Dai in 1999.
Bitgold, described by Nick Szabo in 2005.
Well, I believe that sometimes it's all about the context. There are instances when an innovation is ahead of its time, and the public is not yet ready to embrace it. In such a scenario, a direct copy of a product that would have gone unnoticed at its initial release could experience tremendous success a few years later. Now, I'm not saying that Bitcoin is a mere copy of B-money or Bitgold and that it entered the market at the right time. Bitcoin draws inspiration from these two projects but introduces other innovations, such as the blockchain. However, I do believe that
B-money and Bitgold were ahead of their time, and the public was not yet ready to embrace them. Remember, at the time of these two innovations, we were only just beginning to recognize the potential of the internet, and people were not yet comfortable with online payments via credit cards it had not become commonplace as it is today.
Who is the creator of Bitcoin?
The answer will surprise you: no one knows. Is it a revolutionary act, purely philanthropic, or the scam of the century? Perhaps the future will reveal the truth. One thing is certain, the unknown identity of the creator fuels the legend surrounding Bitcoin and gives rise to wild speculations. However, we do know the pseudonym of the Bitcoin creator: Satoshi Nakamoto (聡中本 or 中本). This pseudonym belongs to the author of the Bitcoin white paper published in 2008. Satoshi is also the founder of the official Bitcoin website (bitcoin.org) and the specialized forum bitcointalk. His profile indicates that he was born on April 5, 1975, and resides in Japan. This is peculiar because he writes in perfect and very British English, and there are no Japanese documents about Bitcoin from that time. Furthermore, certain clues, such as the hours of his activity, suggest that he may be originally from the American continent.
Nakamoto released the Bitcoin white paper online in 2008. He sent it via email to crypto-anarchist mailing lists and discussed it on specialized forums frequented by cryptography enthusiasts. In other words, if you were not part of these communities at that time, it was nearly impossible to come across this paper. The inventor of Bitcoin presented his project with the following words: "I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party." Satoshi Nakamoto was then joined by several individuals who helped him bring his project to fruition.
Satoshi published his final message on the bitcointalk forum (which he created) in December 2010. A few days before his departure, he designated Gavin Andresen as his successor, granting him access to the project and a copy of the alert key, used to notify the network of major events. The last trace we have of Satoshi is a message he sent to Martti Malmi (a contributor to the Bitcoin project) in May 2011, in which he wrote, "I've moved on to other things, and probably won't be around in the future."
We do not know if Satoshi Nakamoto is an individual or a group of people. For a long period, he was the only active miner. It is believed that he possesses over a million bitcoins in a Bitcoin wallet, and none of these bitcoins have been transferred since 2008. The legend suggests that Satoshi Nakamoto may have passed away, taking his secrets and bitcoins with him. If he were a single individual, he would be among the 100 wealthiest people in the world.
Numerous theories exist regarding the identity of Satoshi Nakamoto. One of the most plausible theories suggests that it could be a collaboration between Nick Szabo and Hal Finney. An entire article could be dedicated to this topic. If you want to learn more, I recommend watching the documentary "Banking on Bitcoin," which is captivating.
What does the Bitcoin white paper say?
Definition and Explanation of Bitcoin
Bitcoin is a cryptocurrency, which means it is a digital currency that can only be used with machines (computers, phones, etc.) and the internet. Bitcoin is also a unit of account intended to serve as a medium of exchange, similar to the euro or the dollar. The term "bit" refers to a binary information unit, and "coin" refers to a monetary unit. Bitcoin was created in 2008 during the subprime financial crisis. This cryptocurrency is not subject to any control by companies or states; it is said to be decentralized.
Certain rules are predefined:
It is often mentioned that Bitcoin is a digital, peer-to-peer, and decentralized currency. This may sound a bit complex at first. Let's explore each of these concepts together to better understand what they mean. We will also cover other key concepts of Bitcoin, which you can find in the image below.
Let's consider a concrete example. Jean wants to send 3 bitcoins to Anne. He turns on his computer and logs into his digital Bitcoin wallet on the internet. He enters the transaction details (amount of BTC to send, recipient's wallet address...) and clicks on Send. The 3 bitcoins are then sent to the blockchain through the internet network, and Anne will receive them in her wallet a few minutes later. If Anne wants to use her bitcoins, she simply needs to log into her wallet using her computer (or phone). This is a simplified example; other things happen, such as signing the transaction with your private key to prove that you are the person sending the bitcoins.
Bitcoin is, therefore, a digital currency, a virtual currency. There are no physical bitcoin coins or banknotes; instead, there are digital records that indicate your balance, similar to your bank account.
Bitcoin is a virtual currency, but it has real value since it can be exchanged for euros and is also usable in the real world. Some platforms use the symbol XBT instead of BTC to represent Bitcoin.
Peer-to-Peer System
A peer-to-peer (P2P) system is a computer network model where each client is also a server. This is the case with the BitTorrent protocol, for example, where computers communicate directly with each other (file exchange) over the internet network. Files are transferred directly between the two computers connected to the network, without going through a central server. In this type of system, each computer can send/receive information directly with other computers on the network. Machines connected to each other through a peer-to-peer network protocol are called network nodes.
Bitcoin is based on a peer-to-peer system. Indeed, a bitcoin transaction takes place directly between two computers without a central server. The computer can act as a server (sending BTC) or as a client (receiving BTC).
Example: If Marie makes a bank transfer of 10€ to Julie, Marie's bank will first verify the transaction and give the green light if there is enough money in Marie's account. Then Julie's bank will check the source of the funds and validate the transaction if everything is in order. Finally, Julie receives the 10€ in her bank account.
This concept is entirely centralized, and the bank plays the role of a trusted third party: it verifies and validates your transaction. If you want to send money to someone, your transaction will always go through the bank's servers (the same goes for receiving money). This is what is called centralization.
Bitcoin, on the other hand, operates in a decentralized manner. If bitcoins are sent from point A to point B, they don't pass through the hands of a trusted third party or a central server. Instead, they are verified by thousands of computers worldwide that verify the transactions of network users.
Therefore, there is no longer a single entity that verifies the transaction but thousands of them scattered around the world. We will delve into this concept in more detail in the following part of this chapter.
Other Key Points of Bitcoin.
These points are some of the key features of Bitcoin. The technology and Bitcoin ecosystem continue to develop and evolve, which may lead to new developments and changes in the future.
