Zhou Tong, the founder of the failed bitcoin exchange Bitcoinica, sends this letter to apologize for the exchange's collapse and update customers on recovery efforts. He acknowledges mistakes while young but aims to learn and do better with a new project. Fund recovery from the hacker is in progress with a lawyer's help. The exchange will be liquidated and remaining assets returned to creditors. Tong asks for understanding and support for his new efforts while thanking customers for the life-changing experience of Bitcoinica.
