While in general I tend to agree with the concept that the units were denominated in USD and refunds would have been that amount, in jjiimm_64's case he was explicitly promised his BTC51 back, with no exclusions. If Hashfast was worried about unlimited liability on the BTC51 in the event that Bitcoin went to $1M, the simple solution would be to just not convert that BTC to USD. Yes that opens up the possibility that BTC would go to 0 and their payment is now worthless, but that's the choice they make when they offered him a full BTC51 refund.
J64 was not promised 51 coins back WITH NO EXCLUSIONS. You and the others are adding in a "no matter what"' clause where none existed, or can be reasonably inferred to exist. The legal standard for interpreting such a statement is
ceteris paribus, not whatever wishful thinking buyers' remorse creates after the fact via argumentum ad butthurts.
How was HF supposed to pay for the pre-ordered devices to be built, if they didn't convert the BTC? Magical charity elves? Cargo cult ceremonies?
Nobody was misled into believing in a secret HF escrow or hedge fund. The TOS don't mention escrow or hedge funds and BitPay is an affirmative repudiation of that conspiracy theory.
Thanks for discussing this like an adult, without resort to the childish 'OMG I'M IGNORING YOU LA-LA-LA I CANT HEAR YOU SO I WIN THE ARGUMENT EVEN THO I LOST IN COURT' approach, which is just a concession by another (less honest) method.
It's amazing how many people refuse to acknowledge they were taking a huge risky gamble on ASIC pre-orders, and not simply buying a toaster from Amazon.
