either there is going to be some kind of fantastic trade-in with avalon, or he just doesn't know math.

the last 12 cycles have been 17% every 11days.
even with a low 10% every 11days.
you'll hit 1billion sept 28'2014
considering all the chips being shipped, BFL having 11xxx pre orders alone. and knc coming out with 350g/hash machines
this is not at all unbelievable.

disregarding cost of electricity, pool fee, and unforeseen downtime. @ 70g/hash
you can expect to earn 216BTC over the lifetime of that machine. if you mine TODAY. it gets worse if you put in a more reasonable difficulty figure like 15%.
thats. 7000, BFL 500g/hash machines @ 22500, or 9941 Jupiters @ 7k each, or 30000 bitfury 120g/hash machines @ 2160.
or, a combination of these, you don't think we'll see this many machines come out? this doesn't take into account the BFL and avalon chips for diy boards
edit, where did you get the 75000 theta has number from?

billion difficulty should be about 7100TH
edit, and the fact that we're already 140TH in.
i'd appreciate it if you wouldn't be so disrespectful, i'm only bringing the facts to light, no need to get defensive.
If you can find buyers for 25000 mini rigs, I think BFL wants to talk to you. Especially since non of them will ever pay for themselves it seems.
