Blockchain analysis company Elementus' CEO Max Galka has written a blog post claiming another $260,000 worth of Ethereum (a type of cryptocurrency) has been transferred from about 17,000 Cryptopia wallets (like a bank account for digital currency) since police began investigating. The transfers allegedly began about 1am on Tuesday.
Detective Inspector Greg Murton, of Canterbury police, said it was "not correct" that more currency had been transferred without authorisation.
