We have identified a 51% attack on the CCA blockchain. An attacker was able to sell double-spent coins in CCA/BTC market and crashed the price. Many users were able to buy CCA coins at very cheap prices.
By request of the CCA team, all trades with the attacker will be reversed and users will receive their BTC back. In other words, users that bought CCA from the attacker will have those CCA taken away and they will get back the BTC they paid. This only applies if you still have those CCA. If you already withdrew those CCA then your account will not be modified in any way.
This process will take some time. In the mean time, deposits, withdrawals and trading of CCA will remain disabled.
