I must have missed this. Are you talking about the email where they say that:
Your amount of refund will be the same as the USD amount shown below and in your order confirmation. Our products were purchased based on the purchase price stated in USD. We accepted payment in Bitcoin and other currencies as a convenience to our customers. For the great majority of our Batch 1 customers, we never received Bitcoin, but instead received USD from our payment processor, BitPay, and used the money to pay our suppliers and costs. Most early customers received a preferable exchange rate that reduced our revenue by 8%-10%. We also have customers that have paid in Bitcoin when the exchange rate was far higher than it is today, so our approach to providing refunds in USD is not a policy designed only to benefit us.
Yes. Same quote, I would highlight a different section though:
For the great majority of our Batch 1 customers, we never received Bitcoin, but instead received USD from our payment processor, BitPay
Not saying it's true or false (wouldn't know - it's probably false just because HashFast said it)... just saying that they have severe communication issues.
This of course starts with the fact that they said they can ship in October without communicating any information about how they could possibly do that. They kept hiding behind NDA's.
With open communication they wouldn't have had this many refund requests (well, for starters, because they wouldn't have had this many orders, and the orders they DID have would have known what they were in for), and they WOULD be able to pay out the requests they had - even in BTC.
