Bitcoin price news – today’s value in USD and GBP amid crunch time for the BTC cryptocurrency
BITCOIN is the world's leading cryptocurrency, with its performance shaking up the financial markets.
Its meteoric rise in value last year has been followed by an equally dramatic plunge in 2018 - but what is it worth today?
What is Bitcoin worth today?
At 11.25am on October 16, 2018, one bitcoin was trading for around 4,877.29 Pound sterling and 6,435.01 USD.
Thieves are believed to have swiped £28m of digital currency including Pundi X, Aston and NPER was swiped from Coinrail in June.
Coinrail said 30 per cent of its coins had been stolen, with 70 percent of its coins moved to a more secure "cold wallet", which can transfer coins into a platform that is not connected to the internet.
They did not reveal the value of the theft, but cited industry sources who claimed that hackers stole 40billion won - £27.7million - worth of currency.
The announcement has sent Bitcoin plummeting from more than $7,500 (£5,586) before the weekend to $6,780 (£5,050) - while other digital currencies also recorded large losses.
What is Bitcoin?
Bitcoin is a virtual currency that was created in 2009 by an unknown computer whizz using the alias Satoshi Nakamoto.
Individual Bitcoins are created by computer code.
The total value of all Bitcoin in existence is now more than £112billion.
You are also able to purchase Bitcoin through an online exchange or Bitcoin ATM.
Bitcoins aren’t printed, like pounds, dollars or euros – they’re produced by people, and increasingly businesses, running computers all around the world.
It’s the first example of a growing category of money known as cryptocurrency.
How do Bitcoins work?
The value of Bitcoin, like all currencies, is determined by how much people are willing to exchange it for.
To process Bitcoin transactions, a procedure called "mining" must take place, which involves a computer solving a difficult mathematical problem with a 64-digit solution.
For each problem solved, one block of Bitcoin is processed.
In addition, the miner is rewarded with new Bitcoin.
To compensate for the growing power of computer chips, the difficulty of the puzzles is adjusted to ensure a steady stream of new Bitcoins are produced each day.
There are currently about 16 million in existence.
The Bitcoin protocol – the rules that make Bitcoin work – say that only 21 million Bitcoins can ever be created by miners.
But these coins can be divided into smaller parts with the smallest divisible amount one hundred millionth of a Bitcoin.
This is called a "Satoshi", after the founder.
To receive a Bitcoin, a user must have a Bitcoin address - a string of 27-34 letters and numbers - which acts as a kind of virtual postbox.
Since there is no register of these addresses, people can use them to protect their anonymity when making a transaction.
These addresses are in turn stored in Bitcoin wallets, which are used to manage savings.
