Regardless of this issue being out of their controll, they should have suspended transactions the second they knew there was an issue. When Roi is dependent on price vs. Delivery time these machines will not be as profitable. I would hope bitmain takes care of people who experienced delays due to them still accepting business knowing of the delays. Im expecting a nice few coupons for my delay. Do the right thing bitmain.
What transactions are you suggesting they try to suspend? You can't call "backsies" once you've sent your Bitcoin transaction. Once there's 1 confirmation on the Blockchain, it's in the history books.
That's the beauty of Bitcoin. No chargebacks or pending authorization by institutions or card companies.
The whole issue was with their automated order system pairing with Blockchain. Once Blockchain had issues, they had to manually process each order submitted to them.
Let's see you try to enter a few hundred orders of different quantities at 4 decimals places and ship each unit correctly throughout the world in a matter of hours.
