Topic: BFL ROI FIGURES (Read 2686 times)

Fun fact. As it turned out, in 12/13 we had 1,000,000,000 difficulty, nearly 5x what your default settings projected and we breached 95PH in June rather than november.

Except maybe an SP30.

LOL,no Monarch yet

Oh,well BTC mining is over for me.Finally sold my last Antminers today 

But,got a 5mh Blade replacing them & another coming in 2-3 weeks.

Guess what,my 8.5 mh (I have 8 little Gridseeds & 3 vid cards too) will earn MORE BTC than 1 TH of Antminers by next diff change    & use less than half the power!!!!!!! 

No Monarch will EVER top that!!!!!!!!     (Nor any existing BTC miner    )

One of these cards won't make back more than 200$ of the purchase value.

The difficulty keeps rising at fairly steady rate although it has slowed a little but BFL keeps under delivering on product and it isn't surprising it is being done on purpose. Things never change in the BFL shipping queue.

It is late May 2014. Difficulty is 10.5b, blockchain.info says network hashrate is 80 Petahash. Most likely we'll hit 13b difficulty in June.

They have... and it is clear that with the Monarch they are doing it all over again. Rinse and Repeat Scam.

I for one am lucky, free power at work and all the BFL gear I ordered was free. So for me personally I am not fussed with regard to ROI.

That been said, I wonder why people dont group together and sue/class action BFL, Or is it some misguided hope that miraculously they will receive their gear tomorrow  . . I dont know.

The Jalapeno cost 170 including shipping for quite a while. I don't know why everyone is quoting the current price and also adding on shipping costs to it. I would like to know when it was exactly that people started paying that much for these. They wont be seeing a return I don't think because their shipping date must be a bit away still.

I also dislike that for some reason this calculator won't let you go "back in time." I started my miner a few days ago, not this month, but I can't set that. would be nice if it asked for the day and not just the month, for more clear calculations, and not limit the dates.

I will make back my cost in 19 days I believe. Everything after that is extra.

The difficulty thing is always going to be annoying. At this moment it's quoting only 40%, and it goes up and down. Many people doing calculations elsewhere quote more like 20%. So it's a matter of looking at what's coming right now, where that's going to end, and if we are going to see any real jumps again. I personally think the increases are going to die down after all of this preorder stuff. It would take some real power being sold at a quite a low cost to really see returns after all of this. Mining is closing in on the end of it's real profitability. Everyone is going to have to start actually doing something to make coins, lol.

I seriously doubt we'll see 62% monthly difficulty increases every into the indefinite future, or even anything like that.

Let's say you got a KnC Jupiter in December of this year. According to the default settings, you'd start with a 207,000,000 difficulty in 12/13, and end with a 13,324,000,000 difficulty in 11/14.

That would mean a network hashrate of 9.5 * 10^16, or 95 Petahash.

I'm gonna love seeing my ROI on the $649 30GH unit I ordered in March.  Currently running 15GH worth of USBs and the ROI is eh... when that sucker ships in September-December I'm very curious who else has landed actual hardware, etc.  No telling what difficulty would be, but it was a GREAT bargain when I paid for it in March.

Sweet calc! 1 month ROI just about. Lookin forward to it.

You listed the mini rig as a 60gh single and the 60gh single as a mini rig in your ordering and title above the pictures.

46 would be a slowing of our current pace, but yeah... 

I believe they've fixed the power and price errors?


Just did a few quick calculations with it. I set the shipping to the actual cost from their site, set the Misc costs and pool fee to 0, changed the kW/h costs to .12 to assume cheap electricity, and start in Sept if you'd even receive it by then. Looks like the difficulty increase % went down to 46% from 62% by default.

• Jalapeno 5GH/s
• 30W
• $274 + 34 shipping
• $20 ROI

• Little Single 25GH/s
• 150W
• 1,250 + 34 shipping
• $356 ROI

• Single 50GH/s
• 300W
• $2,500 + 68 shipping
• $711 ROI

• Mini Rig 500GH/s
• 3,000W
• $22,500 + 348 shipping
• $9,950 ROI

This is all assuming they're in your hands by Sept, and difficulty only increases 46%.

I told you months ago in the post BFL and I repeat here. Do not understand how some yankee has not been submitted in BFL with a shotgun and has made a slaughter.

II understand....      Mucho respect, and thank you

Haha no mate, I didn't mean 'your work', as you personally!

like I said, they are not my figures, they are straight up default, with the exception of Sept start, by all means, you are welcome to correct them.
30 watts isn't going to bring back roi anyway.
 

Actually the Little Single SC's are also the wrong way round.

Shame to make something so pretty, and not check your work before publishing details. Perhaps that's homage to BFL after all, lol!

you guys should also play with this, I have been using it for guestimates, and changing power costs doesn't really change the roi much..

just go to genesis http://mining.thegenesisblock.com/ and plug in whatever you feel is right, it wont make much difference.
Every single BFL unit will be operating at a loss from the moment they are plugged in if you get them mid September.

Really, so a single 25 consumes more power than a 30?

And a 60 consumes 10x the power of a 50 and costs $30k??

And the mini500...?!

I'm starting to doubt the validity of this calc that everyone keeps touting the virtues of recently...

EDIT: The 60 and the Mini500 are clearly arse about face. I realise this is not your fault, but you had to see this was massively incorrect.

Why do you think they are selling them

all values are default except starting in september

Yeah, I know.   Shame on me I believed the two months until shipping promise.  ;-(
Only been waiting since this April, I can't fathom the patience of those who have had thousands of $$$$$ tied up in Mini-rig orders since last year!!!

Actually you might want to check all your inputed values...

You might want to check what you've inputed for your power values...
