The bomb threats included ransom demands of US$20,000 in bitcoin. Businesses, schools, universities, newsrooms and religious centres were evacuated in response to the threats
Bitcoin, released to the world in 2009 by a person or people called Satoshi Nakamoto, is not backed by a central bank or a government and is seen as an alternative payment system. In February 2013, Bitcoin went into the mainstream as a monetary crisis threatened to bankrupt Cyprus, seen as a safer bet. Early adopters of Bitcoin have been richly rewarded as the price has soared – in one case, a young Norwegian bought a house from an $850,000 windfall on a US$22 investment.
