I wouldn't pay them a penny more. I'd be looking at a refund right about now. I read on the Alpha forum earlier that only 40% had paid according to Fiaz. I'd say that was optimistic and still probably not enough to get them over the finish line.

Also Fiaz says CC payments will be available next week. If that happens I think more people will pay hoping they get payment protection. But as no announcements have been made we have to assume Alpha are waiting on payments to make up the financial shortfall so they can finish paying for the chips and other components they need.
If so there is absolutely no way you will be  getting your asics in July.  Just look at their timeline to see how far off they are (https://alpha-t.net/news/timeline/). They haven't even completed fab on their enclosure yet, let alone their chips. And what about certification?


They should be in system assembly and testing next week  to meet their stated delivery date. There is absolutely no way that is going to happen. Your ROI window starts diminishing rapidly the closer you get to KNC rollout.

Not to mention Alpha are going to rush this thing out using "risk lot" asic chips which calls reliability into question. But at the end of the day its your call.
