Sold out?
While I am sad for the new bag holders, I'm happy because that means you'll be paying the refunds you owe people and shipping the months delayed products.
Right?
HashFast was open and honest about the reasons for our delay. The delay was for technical reasons, not "fraud" as you falsely claim.
We've provided refunds too all Batch 1 customers who asked. Most choose to be patient and have received their hardware.
As per US law, mail order refunds are in US dollars. Please do not maintain the unreasonable expectation that we're going to break that law.
Because your machine was always priced US dollars, divesting yourself of the delusion you are owed an approximate 800% windfall (based on post-purchase appreciation of a temporary exchange medium provided as a convenience) may also be a good idea.
I guess your lawyer only wanted to take your money, because there's little to no chance he's never heard of 31 US Code Section 5103:
31 U.S. Code § 5103 - Legal tender
United States coins and currency (including Federal reserve notes and circulating notes of Federal reserve banks and national banks) are legal tender for all debts, public charges, taxes, and dues
You refused your machine and you refused a full refund. So you get nothing. Nice legal maneuvering there buddy!

As per US law, bitcoins are not legal tender and thus you are breaking the law by accepting them.
You can't pick and choose which parts of the law you want to follow.
If you accept btc payments and explicitly state that all btc refunds will be returned in the original currency you cannot change your mind when it no longer benefits you.
Fun fact: as per US law, modifying a contract without both parties consent is illegal.
