What is a Bitcoin?

Bitcoins are an online currency that can be used as payment for things like goods and services. You can also hold bitcoins in your wallet and sell or spend them later – they behave similar to physical gold coins – with some key differences: bitcoins exist only online, whereas gold exists naturally in the real world.

The bitcoins themselves are simply files that depict a number of bitcoins connected to your online account, called an address.

You can hold multiple bitcoins in a single wallet and create as many different wallets as you like – a bitcoin wallet does not contain bitcoins but it holds the information required to access them via a private key*. This way bitcoins can be transferred from one person to another, even if they don’t trust each other.

What is a private key*?

What is a private key in bitcoin?

A private key is a secret number that allows bitcoins to be spent. Every bitcoin wallet contains one or more private keys, which are saved in the wallet file. The private key(s) ensure that bitcoins cannot be spent by anybody and only the bitcoins’ owner can send bitcoins from his or her bitcoins wallet.

In order to transfer bitcoins from one wallet to another, the private key stored in the first wallet needs to be combined with a bitcoin address of the recipient’s wallet.

The private key is mathematically related to a bitcoin address and is designed so that the Bitcoin network can determine whether a particular bitcoin address is authorized to spend bitcoins or not.

There are several methods that allow bitcoins to be earned. Bitcoin mining used to be possible with normal computers, but specialized hardware is now required for efficient mining, making it inaccessible for most bitcoin users.

Bitcoin cloud mining contracts are issued according to the Bitcoin network protocol and they depend on its proof-of-work algorithm.

The bitcoins themselves must be mined and this is done by using your computer’s processing power to help carry out intensive calculations that are needed to solve certain math problems, the solution of which would allow bitcoins to be unlocked for transfer into a wallet.

The more bitcoins you can earn using your computer, the faster it will happen because bitcoins are released in blocks expected to be mined every 10 minutes.

As bitcoins are being released by the system, they can also be bought from various bitcoin exchanges or directly from other people using specialized marketplaces called ‘bitcoin exchanges’.

The bitcoins themselves behave like physical gold coins: their value is determined by how much people are willing to buy and sell them for. Their value has been going up since bitcoins were first introduced, and it’s expected to continue going up as bitcoins gain more mainstream acceptance.

History of Bitcoin

history of bitcoin

Bitcoin is a decentralized digital currency created by Satoshi Nakamoto. This person, or group of people, are/is still anonymous to the public. To be more precise there are bitcoins in circulation at this time of writing around 13 million bitcoins.

The creation of bitcoins was divided into two phases: mining bitcoins and earning bitcoins.

Mining bitcoins is done through a process called bitcoins mining which also helps increase bitcoins in circulation.

Earning bitcoins is the process of accepting bitcoins as payment for goods and services you provide to others.

In short, bitcoins are digital coins that can be sent through the Internet with no need for a bank or central authority. When bitcoins are transferred, they are immediately and completely recorded on a public, decentralized and secure ledger: the blockchain.

There is no bitcoins bank or bitcoins company that has control over bitcoins. Bitcoins are not printed money but rather bitcoins are produced by people using computers from around the world running bitcoins mining programs in a process called bitcoins mining. This bitcoins mining serves two purposes: to add transactions to bitcoins public ledger and to release bitcoins in circulation.

How does Bitcoin really work?

“Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing bitcoins are carried out collectively by the network. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.”

A Bitcoin (or BTC for short) is a digital currency, which very simply means that it only exists electronically and doesn’t have physical notes or coins representing it like pounds or dollars do.

The bitcoins are generated by people who run computers that solve mathematical problems on specialised hardware.

There is a limit of 21 million bitcoins (2,100,000 to be exact) which means there can never be more bitcoins than that and bitcoins can’t be duplicated like pounds/dollars/euros etc.

People generate bitcoins by running a software algorithm on their computer, which generates the bitcoins and creates a special file called a ‘blockchain’.

What is a blockchain?

A blockchain can be described as a record that contains all the transactions that have taken place in bitcoins since it began – this is because bitcoins are nothing physical like a note or coin, they are created when transactions take place and bitcoins get bitcoins by being given to the computer that completes the transaction.

what is blockchain

The bitcoins that have been generated so far will all be valid, but they haven’t all been confirmed yet by other people creating blocks.

When creating a block there is a complex calculation which takes place and it has to be done before the bitcoins can go any further.

What is a block reward?

The bitcoins you get for creating a block are called the ‘block reward’; this is paid by all transactions confirmed in that block, so basically bitcoins come from transactions that take place.

block reward

A transaction takes place when digitally signing over bitcoins; this means that bitcoins change hands and they will never exist in just one place at the same time.

To do this, bitcoins use a ‘public key’ and a ‘private key’; bitcoins can be transferred from one account to another by using the public and private keys, which are long strings of numbers and letters.

The bitcoins can only be accessed with the correct private key which is virtually impossible for anyone else to get.

This is where bitcoins get a little confusing since they do have different values, bitcoins can be divided down to eight decimal places and the smallest amount of bitcoins is called a ‘Satoshi’.

The value of a bitcoin will always be more than a Satoshi but it can’t be divided further without changing what it represents, which might only happen in the far future.

What is a Satoshi?

A Satoshi is the smallest fraction of bitcoins that can currently be sent, which is 0.00000001 bitcoins (100,000,000 Satoshis per bitcoin).

Who are miners? How do Bitcoin miners earn?

The miners are the people who run computers that do these types of calculations; bitcoins are paid as a reward for using specialized hardware to confirm transactions, which are encrypted. The bitcoins are shared with anyone else who runs the mining software on their computer.

Bitcoins are generated every time a block is solved; this occurs roughly every 10 minutes, and if miners stop mining for any reason, they receive nothing!

Currently, 1 new bitcoins is generated with every block solved, but this amount will decrease over time. Miners receive bitcoins as a transaction fee along with the bitcoins that are created by solving blocks of transactions.

A new block is only accepted by all of the other computers running Bitcoin after it has been confirmed and agreed upon; to confirm and agree on a new block the computers need to solve a complex calculation. If they can’t, then the block won’t be confirmed and bitcoins will not be released.

Do Bitcoins have value in the real world?

Yes, bitcoins are basically an online version of money. Bitcoins can be exchanged for US dollars and other currencies via bank transfer which is why it has value in the real world. One bitcoin was worth $48,524 on September 18, 2021 and bitcoins can go up or down.

How does anybody make money mining Bitcoins?

You can buy bitcoins online, buy bitcoins at a bitcoin ATM or you start your own computer farm and mine bitcoins. You can make money if bitcoins go up in value compared with other currencies or bitcoins can be used to buy things online.

What is Bitcoins mining?

Bitcoins is the best-known digital currency and is based on complex algorithms with computers doing millions of calculations, basically bitcoins are created electronically. Bitcoins can be bought using cash using bitcoins exchanges that act like ‘online marketplaces’.

Mining bitcoins means running computer code which help run bitcoins transactions. These bitcoins miners run code on their computers which are used to help encrypt bitcoins transactions so they cannot be forged or hacked into.

Miners have to solve a mathematical problem that has bitcoins attached to it and the first person who solves the problem gets bitcoins as a reward for using their computer power.

How can you earn Bitcoins through mining Bitcoins?

You can earn bitcoins through bitcoins mining when you use your computer to help encrypt bitcoins transactions. The bitcoins miners solve a mathematical problem that has bitcoins attached to them and the first person who solves the problem gets bitcoins as a reward for using their computer power.

You can join a community of miner or Bitcoins farm where you pay owner for computing power. You can find bitcoins buyers who will pay bitcoins for bitcoins.

What is Bitcoin’s value? How are Bitcoins used to buy things online?

Bitcoins have become relatively popular on the internet since bitcoins cannot be forged or hacked into. Bitcoins have a monetary value, just like your dollar bills and coins that you use everyday. You send bitcoins over the internet to others who accept bitcoins in exchange for their goods or services.

How can you store Bitcoins?

You can store bitcoins in something called a “bitcoin wallet.”

What are different types of wallets?

There are two types of bitcoins wallets, software wallets and web wallets.

A software wallet can be an application that is run on your computer (which requires you to install it on your computer), or an app with which you access bitcoins in your smart phone (and not much else).

A web wallet is another online storage method for bitcoins, like a bank account (where your bitcoins can be stored securely and where you can use them to pay someone online), except web wallets are more secure than some banking websites.

Pros and Cons of Bitcoin

Bitcoin is a form of virtual currency that can be used as an investment, traded like other currencies on the open market for goods and services. This type of money currently has no physical representation and can only exist in digital format; bitcoins don’t even take up any physical space!

bitcoin pros cons

There are many benefits to using bitcoin: it’s fast (transactions happen within seconds), secure (bitcoin stores all its transactions through encryption), and gives holders the ability to remain anonymous while utilizing the currency because each user has a different address.

The disadvantages include possible cyber-attacks by hackers looking to steal or manipulate passwords, large orders processed faster than small ones, zero customer service for customers experiencing problems with their account balance or transactions if there is no internet connection and bitcoins’ lack of verifiable sources makes them difficult to trust.

Bitcoin is an international currency that doesn’t rely on any country for support. The downside of bitcoin is the volatile price at times, but it still remains one of the safest bets if you need to pay for something quickly and discreetly online.

Bitcoin is a safe and secure way to pay for goods, services, or anything else. Your bitcoin balance can be seen from your computer, smart phone, tablet from anywhere in the world with an internet connection.
