BPMC Launch BF1 USB miner - probably the fastest USB miner in the World

[junp]

i'm interested too to this new usb miners...
HERE you can see that bitfur chips will cost about 0.15BTC (20$) for 3000 units, and provides 2.7GH with 1w of consumption...
a normal USB port provides 2.5W, so they can put 2 chips for each to get 5.4gh@2w and a total cost of about 60$... and I guess to overclock up to 6,75GH@2.5W...
that's a dream come true...


I've done a mistake...it's 0.8W/GHS, so te maximum will be 3,1GHS for erupter...already good!

Well at current pricing (.12-.15BTC) you can get 2.5GH/s for 0.96-1.2BTC with ASICminer block erupters. Maybe even less depending...

These would need to be around .5BTC for me to be interested in buying one or more. I'm doubtful.

I concur. I will be shocked if these are priced under 1 BTC each, and at that price they will never ROI.

At least these show the potential of BitFury chips and hopefully we'll see readily available, cheaper products in the future that actually have a shot at ROI.

I concur. I will be shocked if these are priced under 1 BTC each, and at that price they will never ROI.

I disagree. A 1 BTC price they will have ROI but it will take 3-4 months.

Would I pay 1 BTC, No but nonetheless ROI is possible but small potatoes.

If they come out at BTC0.75  ($37 a GH) I will replace all my Block Erupters with them.

I think I'll wait till October when Bitfury chips are more cheaper, I'm glad to see the product is finished and selling now.

My (conservative) estimates say no ROI for BTC1. More current estimates following recent difficulties say BTC0.75 is too much.

I disagree, so good luck with that! You may want to double check your math because 2.5 GH only earns 0.0145 BTC per day at current difficulty, so you're looking at 69 days to ROI if you pay 1 BTC and exclude difficulty increases and electricity.

The trouble is that difficulty increases are insane right now (~30% every 10 days), and you likely won't get these and start mining before the next difficulty increase to over 110 million.

Excellent news!

Sad that this is going to be limited, but it is a step in the right direction. Hopefully their factories are cranking out these like crazy. If they are priced right (not equivalent to AM, but cheaper), this will sell like hot cakes. I would imagine people waiting for BFL to cancel and buy 2 of these (~5 Ghs). Folks using AM to just add on these miners.

This has to be less than $100 (somewhere close to 50-70 ideally). Otherwise there's no point in introducing something that's not going to see any ROI in atleast a year.

FYI, shipping is from Indonesia!

Well it would be inherently pointless for them to price them above the easily available block erupters, so I think they will be priced just a tiny bit below those.

Interested in this product.
Will wait on prices.

I agree with what kendog77 is saying here.  If you are plugging figures into a mining calculator like the TGB one, you need to throw out the first row of results to get a better prediction on ROI.

wow amazing its nice to see more usb stick miners hopefully price will be under 1btc.

[junp]

chip + usb chipset + development&mounting
the REAL price should be NOT more than 0,3 BTC!!!

[Vorksholk]

At 0.63BTC each, these would be priced very fairly and offer good ROI, much more than that and it's a gamble, much less and BPMC is underselling themselves.

Auction them to highest bidders.  Find the sweet spot on what people are going to pay and then follow through on future orders with that.

Same thing Asicminer did.  Get yours.

Though with AM, there weren't many options available when they did the auctions. If the BF1 USB miners are auctioned at say 0.9 BTC, you can get the asicminer USB sticks for .10 each (0.9 BTC for ~2.6 GH/s). This is bulk pricing, but still.

The only reason to auction would be if they are still behind doing mass production and want to get some units out in the community. I think the folks who paid 50 BTC for the AM blades showed us something (i.e. never bid crazy on these ASICs...)

These are basically the same ones that barntech was selling in the group buy forums, right?

[ooeygooeygold]

Interested will being watching!

Bingo!
