Wow that's crazy to hear, hope everyone that lost their money on there is able to recover.
So the attacker was able to steal 9.7 million coins from Cryptopia? Or are all those coins invalid?
I know you said there was rollbacks, but just want to be sure that person didn't get to keep any of the stolen coins
The coins didn't exist and the exchange is blaming Litecoin code. Unless i missed something huge in the commits, its Litecoin core that they are blaming

Yes the blockchain is fine. Cryptopia just had a way tooo low confirmation count of 6 blocks and no secondary checks on transactions in place. The CSC core indeed is on par with Litecoin so no security breaches there. Just very bad practices from an exchange ....
If you trade or run a CSC service please consider:
- Never leave coins in exchange wallets
- Always trade/deposit/withdraw in small amounts
- Always use a minimum for CSC block confirmations of 50, preferably 100 or more!
- If you run an exchange, ... ALWAYS run checks on transactions against the blockchain!
Until now only about 2,5 mln of the missing 9,7 mln Cryptopia coins have been reported. Can everybody who lost coins please inform us?
Also, there is still 0.64143185 BTC on the buy side on Cryptopia, .... i would move that to AlcurEX or NovaExchange as soon as possible!!!
Thanks!
