The Trust Project is a worldwide group of news organizations working to establish transparency standards.

The crypto industry is not easy to comprehend, considering some unfamiliar terms enthusiasts come across when learning about digital assets. So, before we deep-dive into the topic “What is Bitcoin,” let us first understand what Bitcoin is and how it works. 

Bitcoin is a cryptocurrency that doesn’t rely on a central bank or financial institution. Bitcoin transactions don’t require third-party verification, and Blockchains containing all past transactions are distributed across the internet. In this guide, we will answer your questions about Bitcoin and provide you with all the information you need to understand this exciting new currency.

Bitcoin is a cryptocurrency that is not backed by any central bank or financial organization.

What is Bitcoin?

Bitcoin is a decentralized digital currency that allows you to buy, sell, and exchange directly without an intermediary like a bank. Satoshi Nakamoto, the creator of Bitcoin, noted the importance of “an electronic payment system based on cryptographic proof instead of trust.” With Bitcoin, all transactions are saved open-source on a ledger called the blockchain for anyone to see. The lack of centralization and transparency is what sets cryptocurrencies like Bitcoin apart from regular fiat currencies.

Because no central authority controls Bitcoin, it is often seen as more secure than traditional currencies. Additionally, Bitcoin can be used anonymously, which gives users more control over their personal information. Finally, Bitcoin is not subject to inflation like many fiat currencies, meaning its value is not affected by the government printing money.

Bitcoin has become increasingly popular since its inception in 2009, and it is now one of the most widely-used digital currencies in the world. If you’re interested in buying, selling, or exchanging Bitcoin, there are many different ways. You can find a local exchange in your area or use an online exchange like Coinbase. No matter how you buy Bitcoin, do your research first and only invest what you can afford to lose.

A public ledger is a digital record of all cryptocurrency transactions. The ledger is maintained by decentralized computer network that verifies each transaction. 

Every time someone buys or sells bitcoin, the transaction is recorded in the blockchain. Computers on the network then compete to verify and approve the transaction. This process is known as mining. Once a transaction is verified, it cannot be reversed or altered.

While Bitcoin is often hailed as a revolutionary technology, it is important to remember that it is still in its early stages and has yet to be fully adopted by the mainstream. Some challenges, such as scalability and volatility, need to be addressed before it can truly reach its full potential. However, with more and more businesses and individuals beginning to use Bitcoin every day, it is clear that this digital currency is here to stay.

How Does Bitcoin Work?

Bitcoin works by using a decentralized peer-to-peer network to verify and record transactions. No central authority, such as a bank or government, oversees or regulates the Bitcoin network. Instead, all network users contribute to its overall security and stability.

Each transaction on the Bitcoin network is recorded in a publicly available ledger known as the blockchain. The blockchain contains a record of every transaction that has ever taken place on the network, all the way back to its very first transaction. This allows anyone to see which addresses are associated with how many bitcoins and can be used to verify ownership of those bitcoins.

Before a transaction can be added to the blockchain, it must first go through a process known as mining to verify it. Miners are specialized computers that use their processing power to verify transactions and add them to the blockchain. In return for their work, they are rewarded with newly created bitcoins.

There will only ever be 21 million bitcoins available on the Bitcoin network. This is due to the network’s operating system’s design, which calls for the gradual delivery of fewer new bitcoins.

The Bitcoin network is designed to be only a limited supply of 21 million bitcoins. This is because the software that powers the network is programmed to release new bitcoins at a steadily decreasing rate. As more and more people start using Bitcoin, the demand for new bitcoins will continue to increase, but the supply will not.

Bitcoin is often described as a digital or virtual currency, but it is important to remember that it is much more than that. Bitcoin is new money used to buy things like any other currency. But unlike other currencies, Bitcoin is also a payment network that allows people to send and receive money anywhere in the world without needing a bank or other financial institution. Even though no central authority oversees the Bitcoin network, it is still secure and stable.

Bitcoin key features

Bitcoin has several key features that set it apart from traditional fiat currencies. These features include:

1. Decentralization.

2. Immutability.

3. Pseudonymity.

4. Fast and global.

5. Permissionless.

6. Security.

7. Divisibility.

8. Programmability.

9. Scarce.

Bitcoin decentralization refers to the lack of a central point of control. No single entity, like a central bank or government, can issue new bitcoins or control the network. Instead, the Bitcoin network is powered by its users’ computers.

Immutability means that once a transaction has been recorded on the Bitcoin blockchain, it cannot be altered or removed. This is possible because Bitcoin transactions are verified by multiple computers on the network (referred to as “nodes”), each of which keeps a copy of the blockchain. For a transaction to be considered valid, it must be verified by most nodes.

Pseudonymity means that while all Bitcoin transactions are public, the identities of the parties involved are hidden. Your name or personal information is not attached when you make a transaction. Instead, your transaction is associated with a unique “address” generated for each transaction.

Fast and global means that Bitcoin transactions are processed quickly and can be sent anywhere. Transactions are typically confirmed within 10 minutes.

Permissionless means anyone can use Bitcoin without needing permission from any authority. No restrictions exist on who can buy, sell, or use Bitcoin.

Security refers to the fact that Bitcoin transactions are secured by cryptography. Cryptography is used to verify transactions and prevent fraud.

Divisibility means that Bitcoin can be divided into smaller units. The smallest unit of a Bitcoin is called a “satoshi,” which is one hundred millionth of a Bitcoin.

Programmability means that Bitcoin can be used to create new types of applications. For example, you can create a “smart contract” where two parties agree to certain conditions, and the network automatically enforces the contract.

Scarce means that there is a limited supply of Bitcoins. There will only ever be 21 million Bitcoins created. This scarcity gives Bitcoin value and makes it an attractive investment.

Bitcoin Use cases

Bitcoin can be used for various purposes, some of which can be considered legitimate or not, per each jurisdiction’s laws. Here are some examples of how Bitcoin is currently being used:

  1. Online purchases – Due to its pseudonymous nature, Bitcoin is often used to buy goods and services online without the need for a third-party intermediary such as a bank or credit card company. This allows for increased privacy and decreased fees when compared to traditional methods.
  2. Speculation – Many people purchase Bitcoin, hoping its price will increase in the future to make a profit. While this is certainly possible, it’s important to remember that prices can also go down, so speculation should be done with caution.
  3. Gambling – Bitcoin-based online gambling has become quite popular, as it offers a higher degree of anonymity and lower fees than traditional online gambling sites.
  4. Crime – Unfortunately, Bitcoin’s pseudonymous nature has also made it popular among criminals, who use it for money laundering or purchasing illegal goods on the dark web.
  5. Charity – Some charities accept Bitcoin donations to avoid the fees and restrictions associated with traditional donation methods.
  6. A store of value – Some people view Bitcoin as a potential store of value, similar to gold. This is due to its limited supply and decentralized nature, which makes it resistant to government manipulation or inflation.
  7. Personal payments – Since Bitcoin can be sent directly from person to person without a third party, it’s often used for making personal payments or sending money to friends and family.

While there are many legitimate uses for Bitcoin, it’s important to remember that its pseudo-anonymous nature means that it can also be used for illegal activities. Be sure to research any potential uses of Bitcoin before participating in them.

How to Buy Bitcoin

If you’re new to the world of cryptocurrency, buying Bitcoin can be a daunting task. Here’s a step-by-step guide on how to do it.

Step 1: Choose an Exchange

The first step is to choose a reputable Bitcoin exchange. There are a number of exchanges out there, but the most popular ones are Coinbase, Bitstamp, and BTC-e.

Coinbase is one of the simplest exchanges to use, and it’s available in over 25 countries. Bitstamp is another popular option that’s available in a number of European countries. BTC-e is a bit more complicated to use but has lower fees.

Step 2: Create an Account

Once you’ve chosen an exchange, you’ll need to create an account. You’ll need to provide personal information, such as your name and email address. You’ll also need to create a strong password.

Once your account is created, you’ll need to verify your identity. This usually involves uploading a copy of your passport or driver’s license.

Step 3: Deposit Funds

Next, you’ll need to deposit funds into your account. Most exchanges accept deposits via bank transfer, credit card, or PayPal. Once your funds have been deposited, you’re ready to buy Bitcoin.

Step 4: Buy Bitcoin

Now it’s time actually to purchase some Bitcoin. You can do this on most exchanges using a simple market or limit order.

A market order will immediately buy Bitcoin at the best available price. On the other hand, a limit order allows you to set a particular price at which you want to buy Bitcoin.

Once your order has been placed, it will be executed immediately. Depending on the exchange, you may need to confirm your transaction using Two-Factor Authentication.

Step 5: Withdraw Bitcoin to Your Wallet

Once you’ve purchased Bitcoin, you’ll need to withdraw it to a wallet. A Bitcoin wallet is simply a software program where you can store your Bitcoin. Many different wallets are available, but some popular ones include Blockchain.info, Armory, and Electrum.

There are numerous wallets to choose from, but some of the more well-known ones are Electrum, Armory, and Blockchain.info.

Is Bitcoin a good investment?

Some call Bitcoin a bubble, while others say it’s a significant investment. So, what’s the truth? Is Bitcoin a good investment or not?

Let’s examine the pros and cons of investing in Bitcoin.

Bitcoin pros

1. Potential for huge returns. While risk is involved in any investment, some believe that Bitcoin has the potential to make its investors very rich. For example, if you had invested just $100 in Bitcoin in 2010, your investment would be worth over $4 million today!

2. Diversification. Many experts recommend diversifying your portfolio with different investments. By investing in Bitcoin, you can add another asset class to your portfolio, which can help offset any losses in other investments.

3. Limited supply. There will be 21 million Bitcoins mined. This limited supply could make Bitcoin a valuable asset in the future.

Bitcoin cons

1. Volatile prices. The price of Bitcoin is notoriously volatile and has seen massive swings over the years. While this can make for some great opportunities to make money, it can also lead to big losses if the price falls sharply.

2. Risk of hacks and theft. One of Bitcoin’s biggest risks is the threat of hacks and thefts. Because Bitcoin is stored digitally, it is vulnerable to hackers who could steal your coins. There have been several high-profile hacks of Bitcoin exchanges in recent years, so this is definitely a risk to consider.

3. No guaranteed returns. Unlike other investments like stocks or bonds, there are no guaranteed returns with Bitcoin. This means that you could potentially lose all of your investment if the price of Bitcoin falls sharply.

So, should you invest in Bitcoin? Ultimately, the decision comes down to you and your circumstances. However, if you’re considering investing in Bitcoin, do your research and understand both the pros and cons before making any decisions.

Storing your Bitcoins: Hot wallets vs. cold wallets

There are two main ways to store your Bitcoins: hot and cold wallets. Hot wallets are online wallets connected to the internet, while cold wallets are offline wallets that are not connected to the internet.

Hot wallets are more convenient because they allow you to send and receive Bitcoins quickly. However, they are also more vulnerable to hacking because they are constantly connected to the internet. Cold wallets are less convenient because you have to connect them to the internet to send or receive Bitcoins. However, they are much more secure because they are not constantly connected to the internet.

If you want the convenience of a hot wallet but with increased security, you can use a hybrid wallet that combines a hot wallet and a cold wallet. Hybrid wallets allow you to send and receive Bitcoins like a hot wallet, but they also have the option of storing your Bitcoins offline like a cold wallet.

Whatever type of wallet you choose, it is important to keep your private keys safe and secure. Private keys allow you to spend your Bitcoins, so if they are lost or stolen, your Bitcoins are gone forever. There are many ways to store your private keys, so be sure to choose a method that is right for you.


What is Bitcoin?

Bitcoin is a decentralized digital currency, without a central bank or single administrator, that can be sent from user to user on the peer-to-peer bitcoin network without intermediaries.

Who created Bitcoin?

Bitcoin was created by Satoshi Nakamoto, the pseudonym for an individual or group who designed the original protocol and released the bitcoin software in 2009. 

How does Bitcoin work?

Bitcoin works by using a decentralized ledger, called a blockchain, to keep track of all the Bitcoin transactions that have ever taken place. The blockchain is stored on computers worldwide, and anyone with an internet connection can view it. When a new transaction is made, it is broadcast to the network and verified by the computers that store the blockchain.

Is Bitcoin legal?

This is a difficult question to answer definitively, as the legal status of Bitcoin varies from country to country. In some jurisdictions, Bitcoin is treated as a commodity or property; in others, it is considered a currency or even a form of money. However, there are many countries where Bitcoin is neither expressly legal nor illegal, making its status somewhat ambiguous.

How are bitcoins created?

Bitcoins are created through a process called “mining.” Miners solve complex math problems to verify Bitcoin transactions. This provides a way to create new bitcoins while ensuring that all transactions are secure and trustworthy. In return for their work, miners are rewarded with newly created bitcoins.


Bitcoin is a digital currency that was created in 2009. It is different than traditional currencies because it is decentralized- meaning that there is no one central authority that controls it. Bitcoin works through blockchain technology, which allows users to make transactions without needing a third party, such as a bank.
