Im taking the Holidays into count here. But like I stated I did order them in October.
Also, I dont think theyre saying ADIOS! I think theyre saying hey, I know you paid for 43.8 TH but we cant fill that orders heres an 11TH machine I doubt theyre going to offer me 4 of these to get 44 TH for what I PAID FOR 6 Avalon 741s considering theyve upped the price on those 3 times since I placed my order.
Welp, you may be 100% right and i know the feeling of urgency generated from deprecating profits. I guess its more or less the same emotional issue from waiting for Months for ZOTAC to even acknowledge my RMA request

I guess you're right, they should give you the same hashrate at better efficiency, but i'm not sure Canaan policies are that nice. Hopefully they offer you discounted 821 to fill the order...
They said theyre going to offer a discount on the 821s but I dont know how much of one. I do know it comes with a 3 month wait however.
