I have seen a news about hacked cryptopia exchange that who (hackers) hacked the exchange 16 millions dollars have returned . But i don't sure about the news that 100% right. You can find the news here : http://cryptocrunchapp.com/news/15-days-later-the-cryptopia-hack-continues/
No, they've not returned. They actually deleted Cryptopia's copy of Ethereum private key after copying it for themselves on the day of hack. It's not like that Cryptopia has been hacked again!
The police has already refuted that claim.
https://www.stuff.co.nz/business/110287959/police-dispute-claims-more-cryptocurrency-taken-from-christchurch-company-cryptopiaPolice dispute claims more cryptocurrency taken from Christchurch company CryptopiaBlockchain 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.
I think that @Lafu might work there, maybe he can let us know more about the situation.
Lafu doesn't work there. He is a volunteer chat moderator on their trollbox.
Their staff is currently on leave while the police is investigating.
There is very little confirmed information about what has happened. Everyone is calling it a hack but the statement says "security breach". That could describe a lot of different scenarios that do not involve hacking.
So far the only reliable source of information has been here:
