Should contact cryptopia
This is old news. The Cryptopia daemon was attacked in early September.
A few days later, also in September, the Goldcoin team patched the daemon to repair the known DoS Bitcoin bug and added advanced checkpointing to our client.
So what can not be repaired up to now? It looks like it's been a long time, then what about the people who lost the coin in it? whether the redressal get coins? This is unfortunate but I hope it will be quickly resolved.
