Topic: [ANN] First 500Gh/s BFL unit up and running! - page 5. (Read 30867 times)

So, trying to stay in the realm of a plausible reality..what do you think a 500GH/s unit--in hand--should go for?

Selling your BFL devices now could be more profitable than actually mining with them. There is going to be so many Avalon based devices, KNC, BitFury, and others to drive Gen 1 ASICs soon out of profitability window.

Shit...you noticed.

Shhh....

Take notice he is selling a third of a minirig (500Gh/s) for 150k.

The total unit should therefore go for 450k. (15x the original price)

WAY more than it is actually worth (even in BTC production).

-----------------

I think it is getting "kind of obvious" that people are offloading Gen1 ASICs unto "the greater fool".

I haven't even taken the time to really go on about BFL Singles because I want to see how long it takes for people to notice by the time they get their Single...it is pretty much worth [much] less.

The odd thing is...if they sell it...before they actually get it (as a pre-order). They might actually make more than when they get it and use it.

The funny thing is, there are quite a few selling their Singles and doing just that on Ebay and in the Marketplace.

By the time Singles get into the hands of customers, there will be so many on sale, that the resale price will tank. Like a shark...I am waiting for it.

Funny how you got 2 replies from Luke-Jr paid shill and from kano...BFL's PR is so good!

I didnt I just figured I would leave that out so someone like you could +1 my initial response just to show how ridiculous the price is. 

Don't forget that it then got upgraded to thrice that hash speed.

Wow $150,000 for something that initially was priced at $30,000 and had originally twice the specified hash speed?

Fucking lawlz!

Oh so it's their shit, no wonder nothing came up

Completely documented in the BFL protocol spec
(but apparently they may have changed it a bit ...)

I have facilities setup to handle over 100 500Gh/s units and more contracts are being signed in the immediate future so there are no problems hosting any number of minirigs.


xlink is a chained system and is meant to be more reliable than USB do to hubs not being very reliable.

I do not know all of the issues with xlink, that is a topic for another thread besides this one.


I have been approached by others who would like a get a quick ROI on their equipment purchases since mining equipment is being priced based off of BTC prices.

I am not selling my equipment, I'm mining with it. 

What is x-link? Is there a page with information?

What I actually wrote - not your delusions

The part where you had the minirig in your possession for a while?

What about it? Can you afford the miners now? 

You forgot to read the rest of my post

The person who brought it up came out with different suggestions at the time. I don't recall who it was anymore.

But you summarized at least a part of the problem. A 480Gh/s unit that has a failure can quickly turn into a 50Gh/s unit for several days if the issue isn't addressed using the x-link chained connection. I suppose if all the units are uniformly the same you might be able to extract the bad board (somehow?) and put the entire chain together again minus the bad board. Though I have no clue of what the x-link topology is like or if there is something special in relation to the last board.

At a 20k price point? No, I don't think so.

At 10k? Yeah that sounds good.

I care about mining because in the next month you should have 400+ GH/s for the kind of profitability I am looking for. I stopped looking for options in the sub 100Gh/s category.

By the end of the year, you will need [possibly] double or triple even that much hashing power.

Also, you talk too much smack, you had to be given free units to quiet you down a bit with all your excess complaining and begging for boards to be sent to you. BFL offered you a plane ride (for free) and gave you free hardware. It wasn't until fairly recently that you couldn't even afford one, remember?

Since then you have been pretty weak at the knees [cow towing] whenever someone mentions BFL.

Apparently not...

He's apparently already trying to sell orders (as a broker or not) for more than it is worth. What does that tell you?

What's to fix?

If you connect each of the 8 separately, then they each can fail separately.
If you join them all via x-link, then the x-link chain is indeed a chain where everything below the failed point in the chain will stop working ... as is quite obviously expected.

If the next step was to create some board to handle the partial x-link failure by not having a 'chain' then if the board fails, you lose everything.

I'd be surprised if they bothered to do much about it.
Simply either use x-link, or connect all 8 via a USB hub directly.
This one of gigavps' (that I was testing cgminer on before he got it ) is as described, 8 independent USB devices in hubs - I guess much like the original FPGA MiniRig.

Edit: though I'd also add - since you aren't ever going to get one - why do you care?

I thought it being "shipped" was good enough. 

I thought Giga had 21 500Gh MR's ordered.  They will most likely be split up amongst his other farms.
