What is a Bitcoin and how does it work?

Small wonder that Bitcoin emerged in 2008 just after Occupy Wall Street accused big banks of misusing borrowers’ money, duping clients, rigging the system, and charging boggling fees. Bitcoin pioneers wanted to put the seller in charge, eliminate the middleman, cancel interest fees, and make transactions transparent, to hack corruption, create organic network value, and cut fees. They created a decentralized system, where you could control your money and know what was going on without depending on banks.

Bitcoin has come far in a relatively short time. All over the world, companies, from REEDS Jewelers, a large jewelry chain in the US, to a private hospital in Warsaw, Poland, accept its currency. Billion dollar businesses such as Dell, Expedia, PayPal, and Microsoft do, too. Websites promote it, publications such as Bitcoin Magazine publish its news and price actions, forums discuss cryptocurrency and trade its coins. It has its application programming interface (API), price index, and exchange rate.

Problems include thieves hacking accounts, high volatility, and transaction delays. On the other hand, people in third world countries may find Bitcoin their most reliable channel yet for giving or receiving money.

Understanding Bitcoin – What is Bitcoin in-depth?

What is Bitcoin? [The Most Comprehensive Step-by-Step Guide]

Understanding Bitcoin – What is Bitcoin in-depth?

At its simplest, Bitcoin is either virtual currency or reference to the technology. You can make transactions by check, wiring, or cash. You can also use Bitcoin (or BTC), where you refer the purchaser to your signature, which is a long line of security code encrypted with 16 distinct symbols. The purchaser decodes the code with his smartphone to get your cryptocurrency. Put another way; cryptocurrency is an exchange of digital information that allows you to buy or sell goods and services. The transaction gains its security and trust by running on a peer-to-peer computer network that is similar to Skype, or BitTorrent, a file-sharing system. Satoshi Nakamoto leveraged blockchain technology to allow bitcoin to gain decentralization, complete transparency, and immutability.

Bitcoin Transactional properties:

1.) Irreversible: After confirmation, a transaction can‘t be reversed. By nobody. And nobody means nobody. Not you, not your banks, not the president of the US, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net.

2.) Pseudonymous: Neither transactions or accounts are connected to real-world identities. You receive Bitcoins on so-called addresses, which are randomly seeming chains of around 30 characters. While it is usually possible to analyze the transaction flow, it is not necessarily possible to connect the real-world identity of users with those addresses.

3.) Fast and global: Transaction is propagated nearly instantly in the network and are confirmed in a couple of minutes. Since they happen in a global network of computers they are completely indifferent to your physical location. It doesn‘t matter if I send Bitcoin to my neighbor or to someone on the other side of the world.

4.) Secure: Bitcoin funds are locked in a public key cryptography system. Only the owner of the private key can send cryptocurrency. Strong cryptographic technology and the magic of big numbers make it impossible to break this scheme. A Bitcoin address is more secure than Fort Knox.

5.) Permissionless: You don‘t have to ask anybody to use cryptocurrency. It‘s just a software that everybody can download for free. After you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you from transacting with your own money. There is no gatekeeper.

Judd Bagley: What is Blockchain The creator of bitcoin figured out a way to let two entities confidently trade directly with one another, without the need to rely on all these intermediaries. The key is mathematics. As long as we both trust in math, we can be confident the exchange to occur as expected.

Bitcoin uses public key cryptography and an innovative approach to bookkeeping to achieve the authorization, balance verification, prohibition on double spending, delivery of assets and record inalterability described above. And it happens in near real time at no cost.

Cryptography ensures authorization. You need a private key to transact. And your key is complex enough that it would take the best computer longer than the earth has existed to crack it. In other words, it’s essentially unhackable.

Where can I find Bitcoins?

First, we would recommend you read this in-depth guide for buying Bitcoin.

You can get your first bitcoins from any of these four places.

  • A cryptocurrency exchange where you can exchange ‘regular’ coins for bitcoins, or for satoshis, which are like the BTC-type of cents. Resources:  Coinbase and Coinsquare in the US & Canada, and BitBargain UK and Bittylicious in the UK.
  • A Bitcoin ATM (or cryptocurrency exchange) where you can change bitcoins or cash for another cryptocurrency. Resources: Your best bets are BTER and CoinCorner
  • A classified service where you can find a seller who will help you trade bitcoins for cash. Resources: The definitive site is LocalBitcoins.
  • You could sell a product or service for bitcoins. Resources: Sites like Purse.

Caution! Bitcoin is notorious for scams, so before using any service look for reviews from previous customers or post your questions on the Bitcoin forum.

How does Bitcoin work?

Without getting into the technical details, Bitcoin works on a vast public ledger, also called a blockchain, where all confirmed transactions are included as so-called ‘blocks.’ As each block enters the system, it is broadcast to the peer-to-peer computer network of users for validation. In this way, all users are aware of each transaction, which prevents stealing and double-spending, where someone spends the same currency twice. The process also helps blockchain users trust the system.


“Unlike traditional currencies, which are issued by central banks, Bitcoin has no central monetary authority. Instead it is underpinned by a peer-to-peer computer network made up of its users’ machines, akin to the networks that underpin BitTorrent, a file-sharing system, and Skype, an audio, video and chat service. Bitcoins are mathematically generated as the computers in this network execute difficult number-crunching tasks, a procedure known as Bitcoin “mining”. The mathematics of the Bitcoin system were set up so that it becomes progressively more difficult to “mine” Bitcoins over time, and the total number that can ever be mined is limited to around 21 million. There is therefore no way for a central bank to issue a flood of new Bitcoins and devalue those already in circulation.”

What is Bitcoin? [The Most Comprehensive Step-by-Step Guide]

Is Bitcoin safe and legal?

To see how the system works, imagine someone called Alice who’s trying out Bitcoins. She’d sign up for a cryptocurrency wallet to put her bitcoins in.

The Bitcoin Wallets

There are three different applications that Alice could use.

  • Full client – This is like a standalone email server that handles all aspects of the process without relying on third-party servers. Alice would control her whole transaction from beginning to end by herself. Understandably, this is not for beginners.
  • Lightweight client – This is a standalone email client that connects to a mail server for access to a mailbox. It would store Alice’s bitcoins, but it needs a third-party-owned server to access the network and make the transaction.
  • Web client – This is the opposite of “full client” and resembles webmail in that it totally relies on a third-party server. The third party replaces Alice and operates her entire transaction.

You’ll find wallet technology that comes in five main types: Desktop, mobile, web, paper and hardware. Each of these have its advantages and disadvantages.

Bitcoin as Legal Tender

Currently, Bitcoin is legal tender in two countries – El Salvador and Central African Republic (CAR).


El Salvador

During Bitcoin Miami 2020, Nayyib Bukele – the president of El Salvador – made a game-changing announcement. Bukele said that in 2021, the country would officially accept BTC as legal tender. It made perfect sense for them to do so for multiple reasons.

  1. A significant chunk of the country’s GDP came from international remittances. Folks working in the US would usually send money back to their family via services like Western Union. They end up losing a significant amount of money due to transaction fees.
  2. The El Salvador economy has been suffering due to dollarization. Adopting bitcoin gives them more control over their monetary policies.
  3. Create a friendly ecosystem where Bitcoin entrepreneurs from all over the world can come and create businesses.


Central African Republic

In May 2022, CAR officially made Bitcoin a legal tender. CAR uses the Central African CFA franc – a currency shared by six other Central African countries and governed by the Bank of Central African States (BEAC). The Central African Republic aims to speed up financial innovation by legalizing BTC.


The Real-World Use of Bitcoin as a Payment Method

Bitcoin, the popular cryptocurrency, is not just an investment opportunity but also a viable payment system. Its increasing acceptance by merchants worldwide has made it possible for customers to pay with bitcoin for goods and services. This has opened up new avenues for using digital currency in everyday transactions.

Increasing Acceptance by Merchants Worldwide

One of the key advantages of using bitcoin as a payment method is its growing acceptance by retailers and businesses globally. Many online and physical stores now offer the option to pay with bitcoin alongside traditional payment methods like credit cards or cash. This means that customers who hold bitcoin can conveniently use their digital assets to make purchases without having to convert them into fiat currency.

Fast and Borderless Transactions

Bitcoin’s decentralized nature allows for fast and borderless transactions, making it an ideal payment method for international payments. Unlike traditional banking systems that involve intermediaries and can take several days to process cross-border transactions, bitcoin enables near-instantaneous transfers across borders. This eliminates the need for costly intermediaries and reduces transaction times significantly.

In certain countries, bitcoin has been adopted as legal tender, which further facilitates its use in everyday transactions. For example, El Salvador became the first country to recognize bitcoin as legal tender in 2021. This means that businesses within the country are required to accept bitcoin as a form of payment alongside the national currency. Such adoption provides greater legitimacy to bitcoin and encourages its usage in day-to-day activities.

Seamless Integration with Existing Payment Systems

Bitcoin can be seamlessly integrated into existing payment systems, allowing users to make payments through various channels such as debit cards or mobile wallets. Payment processors have developed solutions that enable retailers to accept bitcoin payments while still receiving funds in their preferred currency, mitigating any potential volatility risks associated with cryptocurrencies.

Decimal Places for Fractional Payments

Bitcoin’s divisibility allows for fractional payments, making it suitable for transactions of any size. Unlike traditional cash where the smallest unit is a cent, bitcoin can be divided into eight decimal places, known as satoshis. This means that even microtransactions can be conducted using bitcoin, further expanding its usability in various industries.

How do I buy and sell stuff with Bitcoins?

Here’s the funny thing with Bitcoins: there are no physical traces of them as of dollars. All you have are only records of transactions between different addresses, with balances that increase and decrease in their records that are stored on the blockchain.

To see how the process works, let’s return to Alice.

Example of a Bitcoin transaction

Alice wants to use her Bitcoin to buy pizza from Bob. She’ll send the bitcoin to Bob’s public address, which is like his bitcoin bank account. She signs off the transaction with her private key to verify that she is indeed the sender of the digital currency. Once the miners have verified the validity of her transaction, the bitcoin get sent to Bob’s public address. Bob can now unlock the bitcoin with her private key. At the same time, Alice’s transaction is broadcast to all the other network participants (called “nodes”) on the bitcoin blockchain and, approximately, ten minutes later, is confirmed, through a process of certain technical and business rules called “mining.” This “mining” process gives Bob a score to know whether or not to proceed with Alice’s transaction.

What is Bitcoin Mining?

Mining, or processing, keep the Bitcoin process secure by chronologically adding new transactions (or blocks) to the chain and keeping them in the queue. Blocks are chopped off as each transaction is finalized, codes decoded, and bitcoins passed or exchanged.

Miners can also generate new bitcoins by using special software technology to solve cryptographic problems. This provides a smart way to issue the currency and also provides an incentive for people to mine.

The reward is agreed-upon by everyone in the network but is generally 12.5 bitcoins as well as the fees paid by users sending transactions. To prevent inflation and to keep the system manageable, there can be no more than a fixed total number of 21 million bitcoins (or BTCs) in circulation by the year 2040, so the “puzzle” gets increasingly harder to solve.

So to summarize the Bitcoin mining process:

  • Bitcoin miners are nodes in the Bitcoin network that possess specialized software technology called ASICs.
  • The Bitcoin miners constantly solve cryptographically hard puzzles.
  • If successful, they get to add a block to the Bitcoin blockchain and get a reward, in return.
  • Currently, the bitcoin block reward is around 12.5 BTC.

There are a few more key things to remember about bitcoin mining or proof-of-work are as follows:

  • It’s extremely difficult to do. Miners often need to spend a lot of money and computing power to successfully mine a Bitcoin. In fact, mining is now so difficult to do that it is impossible for a lone miner to do it on their own. This is why miners often join forces to create mining pools.
  • The metric which defines the degree of toughness of mining is known as “difficulty.”
  • Difficulty is directly proportional to network hashrate. Hashrate is a value that calculates the rate in which miners are executing operations within the ecosystem. Higher the network hashrate, higher the speed and security of the network.
  • When bitcoin hashrate increases, the difficulty increases as well to keep mining under control and maintain a consistent bitcoin block time of 10 mins.

What do I need to know to protect my Bitcoins?

Here are four pieces of advice that will help your bitcoins go further.

As you’d do with a regular wallet, only store small amounts of bitcoins on your computer, mobile, or server for everyday uses, and keep the remaining part of your funds in a safer environment.

  • Backup your wallet on a regular basis and encrypt your wallet or smartphone with a strong password to protect it from thieves (although, unfortunately, not against keylogging hardware or software).
  • Store some of your bitcoins in an offline bitcoin wallet disconnected from your network for added security. Think of them as your bank accounts, while you, generally, keep only some of your money in your wallet.
  • Don’t store your cryptocurrency in bitcoin exchanges or any third-party storage place for that matter.
  • Update your bitcoin software. For added protection, use Bitcoins’ multi-signature feature that allows a transaction to require multiple independent approvals to be spent.

Spending some time on these steps can save you money.

We recommend the Nano Ledger S – Hardware Wallet

Nano Ledger X is just as secure as the other two hardware wallets. It is popular because of its relatively low price of $65 compared to its competitors. Being smaller than KeepKey, it is more portable and easier to carry around. It is a hardware wallet that comes at a very competitive price and is backed by top-class technology.


Bitcoin Distribution

What is Bitcoin? [The Most Comprehensive Step-by-Step Guide]

The graph above shows how many addresses own a particular range of Bitcoins. There are only five addresses that own more than 100,000 BTC. 98 addresses own 10,000-100,000 Bitcoins. A huge chunk of the addresses (45.5%) either own 0.0001-0.001BTC or 0.001-0.01 BTC

What else do I need to know?

Protect your address: Although your user identity behind your address remains anonymous, Bitcoin is the most public form of transaction with anyone on the network seeing your balances and log of transactions. This is one reason why you should change Bitcoin addresses with each transaction and safeguard your address. You can also use multiple wallets for different purposes so that your balance and transaction history remain private from those who send you money.

Your confirmation score: As said, you receive a confirmation score of about 10 minutes before you make your purchase. Different wallets have their own reading.

What is Bitcoin

What are the disadvantages of Bitcoin?

In the beginning, a lot of people were skeptical about bitcoin since nobody knows the identity of its founder- Satoshi Nakamoto. In fact, we don’t even know if Satoshi Nakamoto is a man, woman, or a group of people.

Regarding more practical concerns, hacking and scams are the norms. They happen at least once a week and are getting more sophisticated. Bitcoin’s software complexity and the volatility of its currency dissuade many people from using its payment system, while its transactions can be frustratingly slow. You’ll have to wait at least ten minutes for your network to approve the transaction. Recently, some Reddit users reported waiting more than one hour for their transactions to be confirmed.

Scams to watch out for

The four most typical Bitcoin scams are Ponzi schemes, mining scams, scam wallets, and fraudulent exchanges.

  • Ponzi Scams: Ponzi scams, or high-yield investment programs, hook you with higher interest than the prevailing market rate (e.g. 1-2% interest per day) while redirecting your money to the thief’s wallet. They also tend to duck and emerge under different names in order to protect themselves. Keep away from companies that give you Bitcoin addresses for incoming payments rather than the common payment processors such as BitPay or Coinbase.
  • Bitcoin Mining Scams: These companies will offer to mine outrageous amounts of bitcoin for you. You’ll have to pay them. That’s the last you’ll see of your money (with no bitcoins to show for it, either).
  • Bitcoin Exchange Scams: Bitcoin Exchange Scams offer features that the typical bitcoin wallets don’t offer, such as PayPal/Credit Card processing, or better exchange rates. Needless to say, these scams leave you in the hang while they siphon your dollars.
  • Bitcoin Wallet Scams: Bitcoin scam wallets are similar to online wallets – with a difference. They’ll ask you for your money. If robbers like the amount, that’s the last you’ll see of your deposit. The address, in other words, leads to them, rather than to you.

Of all of these, wallet scams are the most popular with scammers managing to pinch millions.

What are the advantages of Bitcoin?

The best thing about Bitcoin is that it is decentralized, which means that you have a payment system that can settle international deals without messing around with exchange rates and extra charges. Plus, you don’t need to go through a third party like a bank to conduct your transactions. Bitcoin is free from government interference and manipulation, so there’s no Federal Reserve System‍ to hike interest rates. It is also transparent, so you know what is happening with your money. You can start accepting bitcoins instantly, without investing money and energy into details, such as setting up a merchant account or buying credit card processing hardware. Bitcoins cannot be forged, nor can your client demand a refund.

It’s a small wonder that users call Bitcoin “Money 2.0” or that Bill Gates called it “a techno tour de force.”

Tyler Winklevoss, co-creator of Facebook, summed it up when he said:


“We have elected to put our money and faith in a mathematical framework that is free of politics and human error.”

Rick Falkvinge, Founder of the Swedish Pirate Party, predicted that


“Bitcoin will do to banks what email did to the postal industry.”


According to John McAfee, Founder of McAfee,


“You can’t stop things like Bitcoin. It will be everywhere and the world will have to re-adjust.”


Regulatory Landscape and the Future of Bitcoin

The regulatory landscape surrounding Bitcoin is a topic of great importance as governments around the world grapple with how to address concerns related to money laundering and fraud. Each country has taken its own approach, resulting in a varied range of regulatory frameworks.

Governments are keen on preventing illicit activities such as money laundering and fraud that can be facilitated through cryptocurrencies like Bitcoin. As a result, many countries have implemented regulations to ensure greater transparency and accountability within the cryptocurrency ecosystem. These regulations aim to strike a balance between protecting consumers and businesses while still allowing for innovation and growth.

Some countries have chosen to ban or heavily restrict the use of cryptocurrencies altogether, citing concerns about their potential misuse. China, for example, has imposed strict regulations that effectively prohibit cryptocurrency trading and initial coin offerings (ICOs). On the other hand, countries like Japan have embraced cryptocurrencies by implementing supportive regulatory frameworks that encourage their use.

The future of Bitcoin hinges on how it navigates these regulatory challenges while maintaining its decentralized nature. Striking this delicate balance is crucial for ensuring the continued adoption and acceptance of Bitcoin as a legitimate form of digital currency.

One possible outcome is that governments may adopt more favorable regulations over time as they become better acquainted with the benefits and potential applications of cryptocurrencies. This could lead to increased mainstream adoption of Bitcoin as individuals and businesses gain confidence in its stability and security.

Another possibility is that governments may continue to impose stricter regulations, making it more challenging for individuals and businesses to engage with cryptocurrencies like Bitcoin. This could potentially hinder its growth and limit its accessibility, particularly in regions where regulatory restrictions are stringent.

It’s worth noting that while governments play a significant role in shaping the future of Bitcoin, they do not have complete control over its destiny. The decentralized nature of cryptocurrencies means that they operate independently from any central authority or government intervention


Evaluating Bitcoin’s Role in the Financial Ecosystem

Bitcoin, as a digital currency, has emerged as an alternative financial system that operates outside traditional banking structures. It offers unique opportunities for financial inclusion to unbanked populations worldwide. However, the role of Bitcoin as a store of value and medium of exchange continues to be a subject of debate among economists and experts.

Alternative Financial System

Bitcoin provides individuals with the ability to transact without relying on banks or other intermediaries. Unlike traditional currencies issued by central banks, Bitcoin is decentralized and operates on a peer-to-peer network known as the blockchain. This means that transactions can be conducted directly between parties without the need for a bank or any third-party involvement.

Financial Inclusion Opportunities

One of the key advantages of Bitcoin is its potential to provide financial services to those who are currently excluded from traditional banking systems. In many parts of the world, particularly in developing countries, large segments of the population do not have access to basic banking services. Bitcoin offers them an opportunity to participate in global financial transactions, store value securely, and make payments without needing a bank account.

Store of Value vs Medium of Exchange

The debate surrounding Bitcoin’s role centers around whether it is primarily a store of value or a medium of exchange. Proponents argue that Bitcoin has characteristics similar to gold and can serve as a long-term store of value due to its scarcity and limited supply. They believe that over time, more people will view it as a reliable asset class.

On the other hand, critics contend that Bitcoin’s volatility makes it unsuitable for use as a medium of exchange in everyday transactions. The price fluctuations inherent in cryptocurrencies can create challenges when trying to determine their purchasing power or stability over shorter timeframes.

While some businesses accept Bitcoin as payment for goods and services, its adoption remains limited compared to traditional fiat currencies. Factors such as scalability issues and regulatory uncertainty contribute to this hesitation among merchants and consumers.

What is Bitcoin: Conclusion

Frequently Asked Questions

What is Bitcoin?

Bitcoin is a decentralized digital currency that allows for peer-to-peer transactions without the need for intermediaries like banks. It operates on a technology called blockchain, which ensures transparency and security. Think of it as digital cash that can be sent and received globally.

How does Bitcoin work?

Bitcoin works through a network of computers that validate and record transactions on the blockchain. When someone sends Bitcoin to another person, the transaction is verified by miners who solve complex mathematical problems. Once confirmed, the transaction is added to a block in the blockchain, making it permanent and tamper-proof.

Is Bitcoin safe to use?

While Bitcoin offers security features like encryption and decentralization, it’s important to take precautions when using it. Safeguard your private keys (like passwords) and consider using reputable wallets or exchanges. Be cautious of phishing attempts or scams. With proper care, Bitcoin can be a secure payment method.

Can I buy physical Bitcoins?

Physical Bitcoins do exist as novelty items but these are not the same as the digital currency itself. The actual ownership and transfer of Bitcoin happen electronically through wallets and addresses on the blockchain network. Physical Bitcoins are usually collector’s items rather than functional forms of cryptocurrency.

How can I get Bitcoin?

You can acquire Bitcoin through various methods. One way is to buy it from cryptocurrency exchanges using traditional fiat currency or other cryptocurrencies. Another option is to receive it as payment for goods or services you provide. Some individuals mine new Bitcoins by dedicating computational power to solving complex algorithms.

Its almost about that Time of the year when Bitcoin gets to Sky Rocket, so many people are ignorant, they are staying on the sideline, waiting for a move up and the right time to get in. I suspect that the rise will happen in a very short period of time, leaving those waiters behind and their reaction will push the price even higher, so that they will end up under water when btc is consolidating, I know the price will speed up more, then bleed off and have an extended winter and actually go lower than current lows… Then as it goes higher, All we need to do is invest what we’re Holding and make more profit, So we don’t feel the lost in fall of price when it happens again, I discovered a comment of someone giving Accolades to Diego Louis and also thanking him for helping him increase his Portfolio from having 3.4BTC to `*16BTC So i contacted him, Behold I have made 15 Btc in less than two month with his working strategies, if you have lost so much during fall or want to increase your portfolio like me, Reach him on Email Diegolouis000gmail .COM

DO NOT PLAY BITCOIN IF YOU DO NOT KNOW ABOUT IT. There are a lot of person throw money out of the window just because they do not know the information about the Digital Currency. The new trend is always welcome, but you should be smart investors, do not let the page ads flickering comments that make you crazy insane believe. I have lost my mind, I joined the stream of bitcoin response because information will make easy money, young people sure have a few mistakes. And this mistake will probably help you a little miss. I joined the bitcoin a few years ago, Remitato floor is the floor I have chosen, after a time watching the Triggers evaluation, I decided to invest in it. With initial investment $ 1000, I bought 500 TRIG for 0.3200023 and after a few weeks worth 0.3400010, tends to go up, the newcomer saw the will to make a professional Trader Coin . But after that time the floor was hacked to make it freezing, I can not access and some other players said the number of coins in the account vanish without trace. After this incident, the TRAG has been falling completely, despite having recovered the account but the value of TRAG after several months did not go up and the floor of Remitano was disastrous despite gaining ownership. Still persist for a few weeks later hoping for the TRAG to go up but the scandal of the floor is not small. And I have since abandoned the Remitano floor. Unceasing hope, this time I have chosen Binance floor with safety and stability. Binance uses multi-layered architecture, and is committed to security for players. This time I only invested $ 500 because still worried about the safety of the floor. Binance has seen… Read more »

Hey Ameer, do you happen to know a resource to read and gain a better understanding about the current and/or projected domestic legislative roadblocks blockchain technology companies have / will have (ie, specific regulation laws, patenting, etc.)? I’ve been read the cbinsights main read and the http://bit.ly/2oWFNyf market overview, felt they were excellent overviews. However, if anyone has specifics into the legislation, I would greatly appreciate filling in the last gaps.
