I’ve heard a SEPA transfer will allow UK bank accounts holders to utilize European exchanges, unfortunately I am concerned about the legality of these exchanges (ie: who owns/runs the exchange, for example.) As such I would like the company to be based in the UK, where I have more protection if the transaction goes awry.

A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain.
It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system.
The block chain is a shared public ledger on which the entire Bitcoin network relies.
Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain.
Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain.
Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet.
To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network.
All confirmed transactions are included in the block chain.
This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.

Bitcoins have been associated with online criminal and cybercriminals.[209] Used to obfuscate online transactions, bitcoins are seized when deep web black markets are shut by authorities.[210] Criminal activities have stigmatized the currency[211] and attracted the attention of financial regulators, legislative bodies, and enforcement.[212] CNN has referred to bitcoin as a "shady online currency [that is] starting to gain legitimacy in certain parts of the world",[213] and The Washington Post calls it "the currency of choice for seedy online activities".[214] The FBI stated in a 2012 report that "bitcoin will likely continue to attract cyber-criminals who view it as a means to move or steal funds".[209] Criminal activity involving bitcoin has largely centered around theft, money laundering, the use of botnets for mining, and the use of bitcoins in exchange for illegal items or services.
Bitcoin has been a subject of scrutiny amid concerns that it can be used for illegal activities.[20] In October 2013 the FBI of the United States shut down the Silk Road online black market and seized 144,000 bitcoins worth US$28.5 million at the time.[21] The United States is considered more bitcoin-friendly than other governments.[22] In China, buying bitcoins with yuan is subject to restrictions, and bitcoin exchanges are not allowed to hold bank accounts.
Economists defining money as a store of value, a medium of exchange, and a unit of account agree that bitcoin has some way to go to meet all these criteria.[95] It does best as a medium of exchange.[95] (About 1,000 bricks and mortar businesses were willing to accept payment in bitcoins as of November 2013[96] in addition to more than 35,000 online merchants.)[99] The bitcoin market currently suffers from volatility, limiting the ability of bitcoins to act as a stable store of value,[95] and, although bitcoin is the unit of account for the block chain, bitcoin does not see use as a unit of account outside of it.
The price of bitcoins has gone through various cycles of appreciation and depreciation referred to by some as bubbles and busts.[112][113] In 2011, the value of one bitcoin rapidly rose from about US$0.30 to US$32 before returning to US$2.[114] In the latter half of 2012 and during the 2012-2013 Cypriot Financial Crisis, the bitcoin price began to rise,[115] reaching a peak of US$266 on 10 April 2013, before crashing to around US$50.[116] On November 29, 2013, the cost of one bitcoin rose to the all-time peak of US$1,242,[117] but in 2014 the price fell sharply, and as of April remained depressed at little more than half 2013 prices.
Because of their presumed capacity to obfuscate the source of payments in online transactions and bypass money transfer controls by governments and law enforcement agencies, bitcoin came to be used in the deep web black markets.[21] In 2012, it was estimated that 4.5% to 9% of all transactions of all bitcoin exchanges in the world were for drug trades on a single deep web drugs market, Silk Road.[216] The bulk of bitcoin purchases during the time were speculative in nature,[216] so drugs must have constituted a greater percentage of the actual goods purchased with bitcoins c.
Bitcoin is a -based online payment system described by Satoshi Nakamoto[note 1] in 2008[4] and introduced as open-source in 2009.[5] Payments are recorded in a public ledger using its own unit of account,[6] which is also called bitcoin.[note 2] Payments work peer-to-peer without a central repository or single administrator, which has led the US Treasury to call bitcoin a decentralized virtual currency.[10] Although its status as a currency is disputed, media reports often refer to bitcoin as a cryptocurrency or digital currency.[11] Bitcoin is the first fully implemented decentralized cryptocurrency; most other cryptocurrencies are similar and derived from it.
China restricted bitcoin exchange for local currency in December 2013.[80] On 10 April 2014, the People’s Bank of China ordered banks and all third-party payment services to stop dealing with anyone in the bitcoin business.
For four days in December 2013 and January 2014, Yahoo! Europe hosted an ad containing bitcoin mining malware that infected an estimated two million computers.[235] The software, called Sefnit, was first detected in mid-2013 and has been bundled with many software packages.
After the Reserve Bank of India warning in December 2013, a number of bitcoin operators shut shop.[citation needed] The actions of the ED (enforcement directorate) and the I-T (income-tax) department have sent tremors throughout the mainstream bitcoin community in India, if only for the reason that there is still no official regulation on how companies involved in dealing with digital currencies should comply with anti-money laundering and financial transaction laws.
The thief hacks an online wallet service by finding a bug in its website or spreading malware to computers holding the private keys.[28] One way to steal bitcoins is to transfer them from the victim’s bitcoin address using a stolen private key to sign the transaction.[29] If the private key is stolen, the thief can use it to transfer all the bitcoins from the compromised address to another address of his own.
In October 2013, Chinese internet giant Baidu had allowed clients of website security services to pay with bitcoins.[76] During November 2013, the China-based bitcoin exchange BTC China overtook the Japan-based Mt.
Additionally, exchanges where people buy and sell bitcoins for cash, may be required to collect personal information.[54] To maintain financial privacy, a different bitcoin address for each transaction should be used,[55] but multi-input transactions reveal that all their inputs belong to the same owner.
A novel solution is that this is accomplished without the intermediation of any single, central authority, since the maintenance of the ledger is performed by a network of communicating nodes running bitcoin software that anyone can join.[13] Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications.
Most articles about Bitcoins talk about the process of "mining". The Bitcoin network does is indeed made up of a peer-to-peer network of "mining" servers, but what this "mining" software is doing is actually running the network itself.

Assange described the basic premise of this technology as a network of consensus where “you can prove a particular statement, particular consensus and particular contract that happened at a particular time globally and it requires the subversion of every single jurisdiction where people are running bitcoin to overturn that”.
In his conversation with Google executive chairman Eric Schmidt documented in his new book When Google Met WikiLeaks, Assange described bitcoin as “something that evolved out of the cypherpunks” and explained in detail the underpinning technology that made it possible for WikiLeaks to counteract the state’s economic censorship.
Appearing in the form of a hologram at The Nantucket Project conference, Assange spoke of the significance of the block chain, the underlying technology of bitcoin, particularly in relation to journalism and holding those in power to account.
Bitcoin can not only be used to fund revolutionary journalism like WikiLeaks, but also offers a decentralized platform for anyone to directly combat state censorship of information and create transparency for those in power.
In April 2010, Assange took the stage at the Oslo Freedom Forum, where he warned of the enormous force of control and power within the Internet and increasing censorship that threatens the free flow of information.
Yet, long before this new interest and innovation sparked outside the tech community, WikiLeaks editor-in-chief Julian Assange was seeing the promise of the bitcoin technology beyond currency.
