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.
WHY ON EARTH would you cash the refund? Didn't your company's bank account get closed? If the customers paid in BTC, the very least you could do is refund BTC. You are either very, very stupid or a very, very stupid liar. I'm guessing it's the latter.
