One of the biggest Bitcoin currency exchanges has been taken offline after 24,000 units ($250,000; £157,800) of the virtual currency were stolen from its computer servers.
Bitcoins can be used for online money transfers and trades, and the currency uses cryptography to protect it.
But Bitfloor’s founder, Roman Shtylman, said he had kept unencrypted “keys”, which the thief accessed and used to take the money.
Bitfloor’s future is now in doubt.
