In March, Newsweek claimed the founder was Dorian Prentice Satoshi Nakamoto , a year-old father-of-six living near Los Angeles — although a brief interview with Nakamoto himself offered no concrete evidence that it was him.

The machine allows "users to exchange their credits of the digital currency for cash and vice-versa", says the BBC. In May last year, a new bank called Circle also opened its virtual doors to users of the currency. The Boston-based financial services company allows users to deposit currency and see it converted instantly to Bitcoin without any fees. Users are then able to use their account to make transactions.

Circle says that it aims to make Bitcoin easier to use for real-world purchases; at present, the cryptocurrency tends to be used primarily as an investment. You won't need a shovel. Bitcoins are "hidden amid a complex encrypted computer program", explains ABC News. Users have their computers "working round the clock to solve a complicated mathematical problem in order to release new coins".

Of the 21 million possible Bitcoins, about 11 million have already been unearthed. You can also mine coins using your smartphone, says Know Your Mobile — but don't expect quick returns.

Eight hours of running a Bitcoin-mining app, unearthed just 0. That's because finding new coins requires enormous amounts of computing power which has led some hackers to take over unsuspecting users' machines to harness more power. The Bitcoin system is designed so that the work required to find new Bitcoins rises steadily as each coin is uncovered. If you want to buy something using Bitcoins you need to make sure the seller accepts the cryptocurrency. If they do, you acquire the anonymous identification number attached to the seller's "wallet" then move coins from your virtual wallet to theirs.

Bitcoin will "face political pressure and aggressive lobbying from big banks because of its disruptive nature," says Johnson. BITCOIN took a tentative step towards the mainstream today as a new bank called Circle opened its virtual doors to users of the currency, but analysts say it may have a hard time attracting users. The Boston-based financial services company will allow users to deposit currency and see it converted instantly to Bitcoin without any fees. Users will then be able to use their account to make transactions.

What we've tried to do with the service is remove a great deal of the complexity. To use the service, customers will need to link their bank account, credit card or debit card and add money into their Circle account. They can then make transactions using Circle in any currency without conversion fees.

The Bitcoin bungler - a salutary tale

In an effort to assuage people's concerns about storing their money in a virtual currency, Circle displays finances in US dollars rather than Bitcoin. Still, The Verge's Casey Newton says that Circle may have a hard time convincing people to use the service, because "it remains unclear why the average person would conduct a transaction in Bitcoin instead of cash". But, he says, in the long run there may be some advantages: "Advocates for the cryptocurrency say that merchants may eventually offer discounts to Bitcoin users that take advantage of lower transaction fees".

Yet in spite of the fact that the service offers no immediate advantages, Circle already a sizable waiting list of people hoping to sign up. Its future remains far from clear, but as Newton says, the technology and the philosophy behind it seem inevitable. In Brief.
