It would seem two thing's here are an issue.
BA, Next time set a Price, and a date, if oyu miss your date setup a refund schedule, if your a week late = % etc. Would make all of us feel you have a Monetary reason to push for the deadline as you loose money if your late. The issue with BTC is that you can be as late as you want. if you decide to take the millions and run, we can do nothing. With CC/paypal we can always do a charge back if the item's are overly late.
Second;y, Knock off direct sales, if this make's it okay for you. Just announce the next hardware, and let Bob and or someone else do all your sale's. Let DZ run the group buy, etc.
It would seem designing/building and tracking mass single unit order's is what kills a company more than anything.

I look forwad to hearing my two machines are running at DZ
and if it's on time You can be I will be #1 in line for your next round of hardware!
Keep up he good work, good luck.
Now what to do with all these obsolete Miners?
Maybe we all run them for SETI@HOME for a month and scan the known universe?
