Preorders are the cancer of Bitcoin mining. You may or may not get your hardware in time to get at least a little bit of your BTC back. So many companies have run and delivered nothing that it's just not worth it. Buy hardware that is shipping. The ROI on preorders can look tempting, but you'll regret it when you end up with nothing to show for your coins
More eyactly , pre-orders are cancer of your eventual profits, but yeah i definetly agree with you on this one.
You are betting two things that way, both your calculations that the miners are actualy ROI, and the time they should be in your hands.
Keeping in mind that diff. is increasing at astonihing rate, per-orders should be in anycase avoided.
In November of last year it would like as if BFL's 600 GH/s card would ROI in just a few months, but now 7 months later they haven't even started shipping (I think) and will likely now never ROI
BFL's junk would never ROI in
BTC and sadly the Monarch (if ever delivered) may never ROI in even fiat. Considering they starting taking pre-orders last year around this time I think they'll tell pre-order customers they can upgrade to the new "RandomButterflyName" which will be delivered in November 2014 (aka soon or Two Weeks).
BFL has been involved in some really shady dealings.
