I noticed that. And they claimed its unstable and nothing worth to show yet. I dont see why the reaction on that has to be so drastically. At the end show me one ASIC-Producer that had their asic running perfectly at the date they wanted to have it?
A missed deadline would have hurt, but not that badly.
Claiming you have 2 TH and then days later not even being able to show a board is a very clear indication of lying.
If you lie to your shareholders, your price will suffer. And so it has.
