and where is the exchange after cryptopia disappears? Huh

We are still in negotiations with numerous exchanges. As of August 2019 it appears Cryptopia is still in possession of the Aricoin wallet and it has now been moved to a secure server while they investigate their hack in January.

Our research has led us to believe there is approximately 21M ₳ currently in Cryptopia's wallet.

Thank you Victor, we will take this into consideration! Stay tuned.
