Each Bitcoin is a piece of code that has its own transaction log with timestamps. The coins are stored in an owner's virtual wallet and can be transferred and exchanged for goods and services.
Transactions are public and although they are relatively anonymous, it is possible trace identities back to real-life individuals. There is debate as to whether or not Bitcoin should be considered a currency, a commodity, or a hybrid of both.
Risks in Using Bitcoins Bitcoins are associated with a high level of risk, as they are volatile, not time-tested, and currently under no regulation or legislation. There have been incidents of online Bitcoin wallets being compromised by hackers leading to theft of Bitcoins. A currency code is generally built from the two-digit ISO country code and a third letter for the currency.
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. 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. To receive a Bitcoin, a user must have a Bitcoin address - a string of letters and numbers - which acts as a kind of virtual post box.
For example, Japan passed a law to accept bitcoin as a legal payment method,  and Russia has announced that it will legalize the use of cryptocurrencies such as bitcoin.

On 24 January , the online payment firm Stripe announced that it would phase out its support for bitcoin payments by late April , citing declining demand, rising fees and longer transaction times as the reasons.
Among the factors which may have contributed to this rise were the European sovereign-debt crisis —particularly the — Cypriot financial crisis —statements by FinCEN improving the currency's legal standing and rising media and Internet interest.
Nakamoto was responsible for creating the majority of the official bitcoin software and was active in making modifications and posting technical information on the bitcoin forum. The New Yorker's investigation brought up at least two possible candidates: Michael Clear and Vili Lehdonvirta. Fast Company' s investigation brought up circumstantial evidence linking an encryption patent application filed by Neal King, Vladimir Oksman and Charles Bry on 15 August , and the bitcoin.
The patent application contained networking and encryption technologies similar to bitcoin's, and textual analysis revealed that the phrase " The two researchers based their suspicion on an analysis of the network of bitcoin transactions.
Nakamoto's involvement with bitcoin does not appear to extend past mid Other clues suggested that Nakamoto was British: A newspaper headline he had encoded in the genesis block came from the UK-published newspaper The Times , and both his forum posts and his comments in the bitcoin source code used British English spellings, such as "optimise" and "colour".
An Internet search by an anonymous blogger of texts similar in writing to the bitcoin whitepaper suggests Nick Szabo 's "bit gold" articles as having a similar author.
Her methods and conclusion drew widespread criticism. The real identity of Satoshi Nakamoto still remains a matter of dispute. A fork referring to a blockchain is what happens when a blockchain splits into two paths forward. Forks on the bitcoin network regularly occur as part of the mining process.
They happen when two miners find a block at a similar point in time. As a result, the network briefly forks. This fork is subsequently resolved by the software which automatically chooses the longest chain, thereby orphaning the extra blocks added to the shorter chain that were dropped by the longer chain. A blockchain can also fork when developers change rules in the software used to determine which transactions are valid.
On 12 March , a bitcoin miner running version 0. This created a split or "fork" in the blockchain since computers with the recent version of the software accepted the invalid block and continued to build on the diverging chain, whereas older versions of the software rejected it and continued extending the blockchain without the offending block. This split resulted in two separate transaction logs being formed without clear consensus, which allowed for the same funds to be spent differently on each chain.
In response, the Mt. Gox exchange temporarily halted bitcoin deposits. Miners resolved the split by downgrading to version 0. User funds largely remained unaffected and were available when network consensus was restored.
Additionally, FinCEN claimed regulation over American entities that manage bitcoins in a payment processor setting or as an exchanger: In summary, FinCEN's decision would require bitcoin exchanges where bitcoins are traded for traditional currencies to disclose large transactions and suspicious activity, comply with money laundering regulations, and collect information about their customers as traditional financial institutions are required to do.
Basic money-services business rules apply here.
