The endless sea of cryptocurrencies started with a drop called Bitcoin. But, What is Bitcoin? If you’re new to this space, usually, knowing Bitcoin would be your priority. Bitcoin, one of the oldest digital currencies, runs independently of any central authority or government monitoring. Bitcoin(BTC) is instead based on peer-to-peer software and cryptography.

As you now got a gist of What is Bitcoin you might be wondering how it works right? So here’s a quick insight into it.

All Bitcoin transactions are recorded in a public ledger, and copies are kept on servers worldwide. A node, or server, may be set up by anybody with a spare computer. Instead of depending on a central source of trust, like a bank, consensus on who owns which coins is achieved cryptographically among these nodes. Bitcoin itself is a giant cosmos filled with various opportunities and drawbacks. From its mechanism to its working, it is all complex but revolutionary. 

In this article, we will discuss What is Bitcoin, How does it work, Bitcoin Mining and many aspects of the Bitcoin process. So let’s start with the “What is Bitcoin” Guide for you.

What is Bitcoin?

Before knowing what Bitcoin is, you should always remember that cryptocurrencies are subjected to market fluctuations and volatility. Do your research before investing in Digital assets. 

As per Bitcoin’s official website, “Bitcoin employs peer-to-peer technology to function without a central authority or banks; the network manages transactions and issues bitcoins collectively. Bitcoin is open-source; its design is available to the public, no one owns or controls Bitcoin, and everyone may participate. Many of Bitcoin's unique qualities enable intriguing uses that no prior payment system could cover.”

Bitcoin is just another way of keeping your fund transaction private without showing it to anyone. Banks and central authorities always keep an eye on your daily transactions. Every transaction made by you is monitored by someone, isn’t it like breaching your privacy?

Bitcoin was generally made to solve this issue. Before understanding What is Bitcoin fully, we need to rewind how the revolutionary digital asset was created back then.

How Does Bitcoin Blockchain Work?

Now you know What is Bitcoin let’s discuss How it works.

Cryptocurrencies are a component of a blockchain and the network that powers it. A blockchain is a distributed ledger, which is a shared database that records data. Encryption technologies protect data within the blockchain.

  • When a transaction occurs on the Bitcoin blockchain, information from the previous block is transferred to a new block with the new data, encrypted, and the transaction is validated by validators in the network known as miners. 

  • When a transaction is validated, a new block is opened, and a Bitcoin is produced and handed as a reward to the miners who verified the data within the block—they are then free to use, retain, or sell it.

  • When a new block is introduced, the prior blocks become immutable. This ensures that each block grows more secure over time and demonstrates how Bitcoin technology is changing the way banking and financial transactions are carried out. 

It’s basically like school exams. The yearly exams are more complex than the unit tests.

Bitcoin Mining

Bitcoin isn’t physical money or bill which could be exchanged from any bank or authority. Bitcoin is just a code that needs to be cracked to get the reward. But, it’s not as easy as it sounds. 

Bitcoin can be mined using a variety of devices and software. When Bitcoin was originally introduced, it was feasible to mine it competitively on a home computer; but, as the network gained in size, more miners joined, lowering the chances of being the one to solve the hash. You can still mine with your computer if it has updated hardware, but your odds of solving a hash (a string of fixed length) individually are slim. We will talk about Hash later.

You have various alternatives for being a successful Bitcoin miner. You may utilize your existing computer to run Bitcoin-compatible mining software and join a mining pool. Mining pools are groups of miners that pool their computing power to compete with huge ASIC mining farms.

Significance of Bitcoin

Bitcoin is a decentralized technology with far-reaching implications that go beyond cash. Bitcoin is, first and foremost, a social concept. It is possible to reconstruct the human value exchange system by rethinking the financial system.

Consumers in many nations have resorted to Bitcoin to give a more trustworthy exchange value that cannot be regulated by a central authority, while inflation is fast depreciating the local fiat money.

The government's choice to issue currency has a detrimental impact on the purchasing power of its citizens, and the government's capacity to regulate who receives cash, monitor transactions, and set the value of the currency has increased interest in Bitcoin.

Summing up all the things, Bitcoin is:

  • A decentralised token i.e a central entity don’t require to interfere with transactions.

  • More secure than the traditional financial system.

  • A remedy to inflation.

  • A new technical concept to advance the current financial system.

  • Portrays the whole crypto market sentiment (as Bitcoin holds almost 38% of total crypto market capitalization.)

  • Loved by Big personalities and investment gurus.

How to Buy Bitcoin?

There are several methods you can use to buy Bitcoin. Here are some of the most common ways to buy bitcoin:

Cryptocurrency exchanges: Cryptocurrency exchanges are online platforms where you can buy and sell bitcoin and other cryptocurrencies. Some of the most popular exchanges include Coinbase, Binance, Kraken, and Gemini. To use a cryptocurrency exchange, you'll need to create an account, verify your identity, and link a payment method such as a bank account or credit card.

Bitcoin ATMs: Bitcoin ATMs are physical machines that allow you to buy and sell Bitcoin. You can find Bitcoin ATMs in many major cities around the world. To use a Bitcoin ATM, you'll need to have a Bitcoin wallet and cash to deposit into the machine.

Peer-to-peer marketplaces: Peer-to-peer marketplaces such as LocalBitcoins and Paxful allow you to buy bitcoin directly from other individuals. To use these marketplaces, you'll need to create an account and verify your identity. You can then browse listings from other users and choose a seller to buy Bitcoin from.

Bitcoin futures: Bitcoin futures are financial contracts that allow you to buy or sell bitcoin at a specific price at a future date. To buy bitcoin futures, you'll need to use a futures trading platform such as BitMEX or CME Group.

Bitcoin mining: Bitcoin mining is the process of using specialized computers to solve complex mathematical problems and earn new bitcoin. While it's possible to mine Bitcoin on your own, it's typically not cost-effective unless you have access to cheap electricity and specialized mining hardware.

Where to Buy Bitcoin?

Bitcoin is a virtual currency that only can be traded online. Exchanges are a useful alternative since they provide a wide range of services and more cryptocurrencies for trading, allowing investors to buy, sell, and hold bitcoin while also allowing users to withdraw money to their online wallet for protection.

Some of the popular exchanges are Binance, Coinbase,, Kraken etc.

After registering into the desired exchange, you need to make payments to acquire Bitcoin. Once the payment is approved by the exchange, your Bitcoin will be reflected in your wallet. 

Bitcoin or any digital token could be reserved in Cold wallets and Hot wallets. It solely depends on the user where they want to keep their Bitcoins. Although, it’s easy to carry Bitcoin in cold wallets (Wallets associated with exchanges) are always on the verge of getting exploited by hackers. However, Hot wallets or Hard drive wallets are more secure if one wants to keep Bitcoin away from the internet touch. 

How to Use Bitcoin?

Initially, Bitcoin was primarily used as a digital currency for online transactions, but its use cases have expanded significantly over the years. Today, bitcoin is used for a wide range of purposes, from investment to online shopping to charitable donations. Here are some of the most common uses of Bitcoin:

Online transactions: Bitcoin was created to be a decentralized digital currency that could be used for online transactions without the need for intermediaries such as banks. Today, many online retailers and service providers accept Bitcoin as a form of payment, including, Microsoft, and Expedia.

Investment: Many people view Bitcoin as a digital asset that has the potential to increase in value over time. As a result, they choose to invest in Bitcoin either directly by purchasing the cryptocurrency or indirectly through investment vehicles such as exchange-traded funds (ETFs) or futures contracts.

Remittances: Bitcoin can be used to send and receive money internationally with lower transaction fees than traditional remittance services. This makes it a popular choice for people who need to send money to friends or family members in other countries.

Charitable donations: Some charities accept Bitcoin donations, which can be an easy and secure way to make a contribution. Bitcoin donations can be anonymous and are often processed quickly and without fees.

Store of value: Some people view Bitcoin as a potential alternative to traditional currencies, particularly in countries with high inflation rates or unstable economies. Because Bitcoin is decentralized and not subject to government or financial institution control, some people believe it may be a more stable store of value than traditional currencies.

What Makes Bitcoin a New Kind of Money?


Bitcoin is a decentralized digital currency that operates independently of any central authority, such as a government or bank. This means that no single entity controls Bitcoin, and it is not subject to the same regulations and restrictions as traditional currencies. Decentralization also allows for greater security and privacy, as transactions are not reliant on a central intermediary.

Peer-to-peer network

Transactions are processed directly between users without the need for intermediaries, making it a peer-to-peer network. This allows for fast and efficient transactions with lower fees than traditional payment methods. It also makes Bitcoin more accessible to people who may not have access to traditional banking systems.

Blockchain technology

Bitcoin uses blockchain technology to record and verify all transactions made on the network, making it secure and transparent. The blockchain is a decentralized ledger that is maintained by a network of users, making it difficult for anyone to manipulate the system. This ensures that transactions are secure and cannot be altered after they are recorded.

Limited supply

Only 21 million bitcoins can ever be created, making it a deflationary currency with the potential to increase in value as demand grows. This limited supply is built into the Bitcoin protocol and ensures that the currency is not subject to inflation caused by governments printing more money.


Bitcoin can be used for a variety of purposes, including online transactions, peer-to-peer payments, and even as a store of value similar to gold. It is also increasingly being accepted by merchants as a form of payment, giving it more widespread use as a currency. This versatility makes Bitcoin attractive to a wide range of users, from individuals to businesses.

Increasing acceptance

More and more merchants are accepting Bitcoin as a form of payment, which gives it more widespread use as a currency. This acceptance is driven by the benefits of lower fees, faster transaction times, and increased security compared to traditional payment methods. Additionally, Bitcoin's limited supply and potential for value appreciation make it an attractive investment opportunity for some.


Bitcoin Price Trend

Bitcoin is one of the most volatile crypto tokens out there. Bitcoin investors have seen various Market upsurges and Downturns. From a zero-worth asset, Bitcoin’s journey to reach $69,000 is remarkable. Although, numerous market turmoil, financial crisis and pandemic took the value down still the project holds a lot of potential.

As per the trading view chart analysis, downslope price action could be seen. This inclined line is acting as a resistance to the Bitcoin price hike. Once the value goes par this line, Bitcoin could see a bull rally.

Risks Associated with Bitcoin

Bitcoin is by far the most successful virtual currency today, but like with every new frontier, there will be challenges. Despite Bitcoin's recent popularity, investing in cryptocurrency has some severe dangers.

With so many individuals racing to participate, it's critical to be aware of the risks associated with this new market. Here are the top ten hazards of Bitcoin investment, as well as how to prevent them.

  • Market Volatility

The Crypto market especially Bitcoin is subjected to immense volatility. The price swing is just uncertain. Many investors have drained their life savings into Bitcoin. As the market is very unpredictable, prices could drop severely. Like in 2012, Bitcoin price soared more than 1200% in just a few months. In contrast, Bitcoin's price is more than 70% down from its all-time high at the time of writing this blog.

  • No Regulation

The bitcoin market is now lacking substantial regulations. The government lacks a clear stance on Bitcoin; the business is simply too nascent. Regulations are required to mature a market. A draft law stating the new worldwide regulatory framework for cryptocurrencies was recently introduced in the US Parliament. Currently, bitcoin is not a widely accepted currency, but the future is unpredictable.

  • Unsustainable

Bitcoin works on the Proof of Work mechanism which makes the crypto unsustainable. To mine a Bitcoin blocks a huge amount of energy is required. Miners require a large amount of computer power to tackle challenging mathematical problems. It leads to the depletion of precious resources (money, energy, space, hardware). It is estimated that by the end of 2018, transaction verification would consume 0.3% of the world's electricity.

Each Bitcoin transaction consumes 980 kWh, which is enough to power an ordinary Canadian family for more than three weeks. This isn't only a Bitcoin problem. Almost every other cryptocurrency that employs the Proof-of-Work (PoW) consensus algorithm has a similar issue.

  • Limited Utilisation

Due to its unregulated price, Bitcoin is not accepted widely. This issue points out the basic necessity of any currency to be exchanged in return for some values. Bitcoin can’t be exchanged everywhere. It’s still not seen as a new payment option hence the use of Bitcoin in the traditional market is still a vague topic.

However, few businesses accept it as a valid form of payment. Currently, bitcoin trades are permitted on a few online retailers, like Overstock, Newegg, and Monoprix. Furthermore, bitcoin owners may use their coins to book flights with firms such as AirBaltic, Air Lituanica, and Unfortunately, many businesses do not accept Bitcoin as a valid form of payment.

  • Scams

In addition to cybercrime, the Bitcoin market has a good degree of fraud. Buyers and sellers are trying to trade bitcoins online, but due to the cryptocurrency's popularity, some of these exchanges may be fraudulent. 

The Consumer Financial Protection Bureau and the Securities and Exchange Commission have both issued warnings about these transactions, in which naïve investors are cheated out of their bitcoins through fraudulent trades. This absence of security poses a significant danger to investors. 

  • Quantum Attack

Although, Bitcoin’s SHA-256 Hash function is still considered one of the most secure algorithms. 51% Attacks are very rare and one of the most effective to date to exploit the whole system. Bitcoin is considered resistant to 51% Attacks.

But, Bitcoin’s SHA-256 could be easily breached by Quantum computing as it could make several calculations within a seconds. It is capable of degrading the RSA encryption used in Bitcoin's functioning. Without this, Bitcoin data transit over the internet will be unsafe. When this happens, it will be very easy to mimic actual users' transactions. It will also allow people to take coins from one another.

History of Bitcoin

In October 2008, a person or group going under the pseudonym Satoshi Nakamoto launched the Cryptography Mailing List at "I've been working on a new peer-to-peer electronic cash system with no trusted third party," the anonymous individual or group claimed. This now-famous white paper, "Bitcoin: A Peer-to-Peer Electronic Cash System," published on, would become the Magna Carta for how Bitcoin functions today.

The first Bitcoin block, Block 0, was mined on January 3, 2009. This is also known as the "genesis block," because it contains the text: "The Times 03/Jan/2009 Chancellor on edge of second bank rescue," which might be proof that the block was mined on or after that date, as well as significant political commentary.

Bitcoin was founded and came into operation in 2009, during the economic downturn. Bitcoin was designed to be a peer-to-peer electronic cash system, but it has also attracted the interest of crypto-curious investors as a store-of-value currency equivalent to gold.


In conclusion, Bitcoin is one of the first digital currencies, built on peer-to-peer software and cryptography. It operates autonomously of any central authority or government oversight, and it is open-source, with no one owning or controlling it. Despite several important shortcomings, it is gradually entering the global economic consideration. The recent growth in Bitcoin usage is a significant component that will lead to the crypto king being accepted everywhere.

In this article, we have covered “What is Bitcoin”, How it works, what is Bitcoin mining, its price trend, RIsks and its History so far. But this isn’t the end. There’s a lot to explore about Bitcoin as it’s endless.
