Second."nobody in the right mind will keep doubling the hashrate of the network every month if they are loosing money. The hashrate of the network will keep growing only if the bitcoin value goes up again." I think this is only half true because when the price go down a lot of orders remains undelivered (same if the price go up) so the network difficulty don't follow the BTC price in real time but with a lot of delay.

+1 for this
There are too many people outside which have free electricity or just can not calculate Roll Eyes

"We trust that Bitcoin mining will be profitable in May as well or all the Bitcoin mining will stop. The online profitability calculators are wrong just because nobody in the right mind will keep doubling the hashrate of the network every month if they are loosing money. The hashrate of the network will keep growing only if the bitcoin value goes up again. For this reason and because we provide the lowest prices possible we do not think that our miners will have a negative return of investment. However, we understand that you might not agree with us and we'll offer you the refund if you decide to go ahead with it."

Difficulty jumped by about a billion Saturday.

First a little bit of chartism for the serious investors Grin

lol

If you make a quick analysis of the Bitcoin chart the price has a strong support in the zone between 370 and 400 $ (the lost of this support means the price will drop deep to the bottom) in the other hand the next resistance is first the 560 $ (200 days moving average) and after that the zone of 600 $ if the price can break this resistance in the next days/weeks we will see the beginning of a bullish trend. In my opinion this option is more probable but of course I can be wrong.

full mask of 28nm takes ~80 days. from there, chips are packaged and sent to the rig builder.. there they have to be built, packaged, burned-in and tested.
i'll let you work it out.

How long did it take them with the 65nm? Like, three months after the chips were supposed to leave the foundry? Probably won't take that long for the current kick at the can, but considering all the lessons BFL has learned since this is their second ASIC, you could probably take 3 months as a best-case bet.

full mask of 65nm is ~63 days.

Tape out was February 23. The fabrication process takes just under 2 months from what I've seen/read.

Chips have to be packaged which can take a week or so, then of course they have to be tested.

I've requested a refund via email over a week ago for my order and have gotten no response. I opened a ticket on their website and they closed it with no response. Has anyone managed to get a BTC refund from them? How long did it take? What method did you use to get a response from them?

As per David105396 on the eCoin Talk forum:

"I am very confident that the deadline [of May 1st] will be made and shipping will start on time. I will personally vouch for this. "

I hope this is the case! But we heard everything was on time until the end of January the last time. We'll see...

I skimmed through the recent discussion and did not see an update from Blackarrow. Can someone re-post the latest update from Blackarrow? I am hoping the April/May shipping is still a possibility (even if remote).

Any chance of an increased hashrate for the X1 and X3?

Doubtfull imo. Lets just hope they actually end up pumping out a product.

Any delay beyond May 1st has to come with a HUGE hashrate upgrade. Like 300%

You know, I was sitting here today and thinking.
What would complete my day and kick start my weekend.
Just then I got an email notifying me of a new post here, and what do you know.
This insightful and unbelievably awesome post made me realize that that is exactly what I've been missing.

So, I would like to thank you for such an unbelievable contribution to this thread.
May your wisdom bring our ASICs to us at a much faster rate then it was possible just a few short minutes ago.

I for one am inspired to call up BA and offer any accounting services...pro bono of course...that they may need in order to get this done faster.

Simply amazing!

Lol, I did.., but I am only IT side.
My accounting is not so good.
