You have time to complain to the forum, bother the State of Californa, and hire a lawyer.
But you don't have time to actually pursue a case in court?
More like, you know your quest for a ~600% gain for doing nothing is doomed to fail if it ever reached a proper venue.
Better stick to the court of public opinion, where your narrative of victimization may fool a few rubes.
"Emotional tolerance?" IOW, you can't stand the idea of a judge ruling your demand for a free pony named Windfall is ludicrous. That buyer's remorse is just awful, isn't it?

Why did you agree to be a windfall?
How can you offer full btc refunds thinking the price will be stable? Are you new to bitcoin? Since the invention of bitcoin, we have yet to see a period longer than a few days let alone months where the price did not swing dramatically. If you did not understand that then you should not be doing business in bitcoin.
Then you create a windfall protection plan by offering possible compensation for delays.
Then you decide to give neither btc refunds or the extra hashing power which was the only reason people decided to go with your company.
Then you complain that it is the customers who are mistakenly looking for a windfall when you sold them a windfall.
Good luck in court.
Thanks for helping make my point, that HashFast's ToS do not provide for windfalls or otherwise create unlimited liability on our part in the event of massive BTC/USD fluctuations.
Any interpretation of the ToS claiming HashFast must provide windfalls or otherwise be infinitely liable for BTC/USD fluctuation is not reasonable, much less enforceable.
