Update 11/9/2013: TerraHash is still in business, we have not filed for bankruptcy yet. The refund from Yifu was cashed immediately back then, we did not make any profits from the recent surge in BTC prices. Again, we are still committed to provide as much refund as possible. I will update again in a couple days on how we are going to proceed with that.
Amir:
Prove that you cashed out the refund from Yifu. Post the transaction details including the wallet addresses (Terrahash's wallet to the Exchange's wallet), the receipt for converting BTC to fiat currency (USD), and the wire transfer details showing the money was sent to Terrahash's account. Post Terrahash's bank statement that shows the cash from the BTC that Yifu sent you. Prove what your saying is true.
