Ether is the second most valuable form of digital currency after bitcoin. The technology it runs on is called Ethereum, first described by the 19-year-old bitcoin programmer Vitalik Buterin in 2013, who envisaged it as an improved version of bitcoin. Like bitcoin, it allows anonymous payments to be sent across the internet without the need for a bank or other third party.
After ether was launched in 2015, its value increased more than 2,300 per cent in one year.
