Well, topic says most of it...
Does anyone else who purchased a #3 have the same worries?
My greatest concern is never to see a ROI and my second concern is we won't see a ROI within year.. with ROI I mean mainly in BTC, not fiat money but speculate freely please. add 25 % VAT on price of the avalon for european customers.
What is the worst case scenario in your opinion?
I think the one year ROI is the worst case scenario. Even if BFL produces all their preorders and even if ASICMINER deploys all of their 262 TH, Avalon #3 will be profitable. It will just take longer.
