NiceHash, which lost about $64 million worth of bitcoin in a hack on its payment system on Wednesday, said the attack was probably made from a non-EU IP address. The Slovenian cryptocurrency mining marketplace matches people looking to sell processing time on computers in exchange for bitcoin. “It is very probable that the attack was made from an IP address outside the EU,” head of marketing Andrej Skraba told Reuters on Friday. NiceHash investors came from “all over the world,” he said. Head of NiceHash Marko Kobal said in a Facebook video recording that the hack was made by using the credentials of a NiceHash engineer. Earlier on Friday Bitcoin fell more than 12 percent on the Bitstamp exchange to about $14,500.
