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 the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain.
Bitcoin is unique in that there are a finite number of them: 21 million.
Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.
[17] As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.[18].
Research produced by University of Cambridge estimates that in 2017, there were 2.9 to 5.
NOTE: Warning: Accepting Bitcoin is a complex process and involves many risks. Before accepting Bitcoin, you should thoroughly research the digital currency and become familiar with the technology behind it. Additionally, you should be aware of the risks associated with accepting Bitcoin such as fraud, cyber-theft, market volatility and taxation. You should also understand how to securely store your private keys and how to move your funds safely. Otherwise, you may face financial losses due to incorrect handling of Bitcoin transactions.
8 million unique users using a cryptocurrency wallet, most of them using bitcoin.[19].
The first wallet program was released in 2009 by Satoshi Nakamoto as open-source code.[10] Unlike traditional fiat currencies, which are issued by central banks, Bitcoin has no central monetary authority. Instead it relies on an peer-to-peer network made up of its users’ computers to verify and record transactions. In the case of Bitcoin, users send payments by broadcasting digitally signed messages to the network using bitcoin cryptocurrency wallet software.
Transactions are recorded into a distributed, replicated public database known as the blockchain, with consensus achieved by a proof-of-work system called “mining”. Satoshi Nakamoto wrote the Bitcoin code in C++ and released it in January 2009 on SourceForge under an open source MIT License.[11].
In January 2009, Nakamoto released the first bitcoin software that launched the network and the first units of the bitcoin cryptocurrency called bitcoins.[12][13] Mining is a record-keeping service done through the use of computer processing power.[f] Miners keep the blockchain consistent, complete, and unalterable by repeatedly grouping newly broadcast transactions into a block, which is then broadcast to the network and verified by recipient nodes.[33] Each block contains a cryptographic hash of the previous block,[33] using the SHA-256 hashing algorithm,[7]:ch.
7 which links it to the previous block,[7]:ch. 7 so that if one block is tampered with it would be very difficult to change all subsequent blocks.

When you lose your Bitcoin, it can be very difficult to get it back. There are a few things you can do, but it is important to remember that there is no guarantee that you will be able to get your Bitcoin back. The first thing you should do is try to find out where you lost your Bitcoin.
When you receive Bitcoin from someone, it is typically in the form of a transaction. Transactions are how Bitcoin is sent from one person to another and are recorded on the blockchain. In order to receive Bitcoin, you will need to have a Bitcoin wallet.
Assuming you already have a Bitcoin wallet set-up and you are looking to receive a payment, there are a few things you need to know. When someone wants to send you money, they will need two pieces of information from you in order to do so: your public Bitcoin address and your private key. Your public address is like your email address – it’s what people will use to send money to you.
Bitcoin mining is the process of verifying and adding transaction records to the public ledger (known as the blockchain). The Bitcoin network relies on miners to verify and validate transactions, and they are rewarded with cryptocurrency for their efforts. In order to mine Bitcoin, you will need specialised hardware known as an ASIC (Application Specific Integrated Circuit).
When Bitcoin Cash (BCH) hard forked away from the Bitcoin (BTC) blockchain on August 1st, 2017, a new cryptocurrency was born. Up until recently, it was pretty difficult to claim your Bitcoin Cash if you held your BTC in a software wallet. However, with the release of the new Coinomi wallet, claiming your BCH is easy as pie!
