So let me get this straight. If 1M$ per bitcoin is too much, if 500$ per bitcoin is too much who sets the limit? How should customers interpret the statement from the HF rep? If bitcoin was 200$ would they get 51 bitcoins as refund? What about at 150$ per bitcoin?
Also by your statement HF never intended to fully refund everyone from Batch 1 after their missed deadline. They had some money for some of the customers, but not for all. So they broke their own ToS by not having money for everyone from Batch 1. Am I reading this correct? HF took money for 4(?) batches and never had any plan/back-up plan to fully refund everyone from Batch 1.
The only legal course of action was for HF refund the purchase price (which as always denominated in USD) in fiat.
It would be no different if you wanted a refund for an exact number of Euros or Yen.
HF is simply not liable for fluctuations in media of exchange provided as a convenience. That's not how it works. Ask any lawyer.
This has already been explained several times; you and Skye are unbelievably slow learners.
. They have lied in their ToS plain and simple. Thank you for clarifying that!
