Bitcoins cannot fail to pique the interest – entirely contained within the digital world and with no physical manifestation, they effectively automate the role of third-party institutions (banks and governments) in transactions. This means not only an elimination of the fees attached to governing bank transaction, but that the currency “doesn’t care about borders” and thus is unaffected by currency exchange rates. Transfers from anywhere, to anywhere, are quick, cheap and anonymous, and all are recorded on a public ledger rather than by a single institution. According to its developers, Bitcoin “puts the control back in the hands of everybody”, and the wider social implications of bringing people from all corners of the world into the global financial system could be huge.
