Well, topic says most of it...

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?

Does anyone else who purchased a #3 have the same worries? Feel free to speculate even if you haven't ordered one yourself.
