According to local newspaper Portal do Bitcoin, once an error is detected cryptocurrency exchange immediately began to get in touch with a user named Kaique Nunes. He, in turn, spoke about the situation in the following way:
"In early November I issued a standard request for withdrawal of funds. After some time I was contacted by representatives of Bitcambio and said that sent me much more of that which I have indicated in the application. Then they asked me to visit a notary's office and sign some documents. I thought it was a coup".
According to Nunes, it seemed to him that some hackers got their personal data, but for the full set of information they need his signature. In addition, the user decided that he was facing a rogue employee trying to scam users, therefore, did not answer the incoming message. However Bitcambio still insisted on cancellation of the transaction. The process could be only be completed at the notary office, where Nunes will need to provide a document sent by the exchange to the e-mail and leave his signature.

It turned out that the administrator of this community is Rodrigo Souza, one of Bitcambio’s suppliers. He replying to Nunes recognized the exchange’s error and added that the exchange operates in accordance with the law and is not afraid to attract too much attention. In conversation with local media Souza said the cause of the error was a serious bug, and also added that the cancellation of the transaction of such huge amount is possible only after the consent of the user.
Currently both parties to settle the consequences of technical failure. Exchange promised to Nunes to reimburse all losses associated with the appeal in a notary's office.
