STOP!!! Do not buy that new ASIC ! And here's why...

[timk225]

I was just looking at the KNC site for their various miners, the high end Jupiter model hashes 550 Ghash for $4,995.00 .

I'm telling you, DO NOT BUY ONE OF ANY MODEL!

Why?  Simple economics.  Run the numbers with me:

At current BTC difficulty of 267 million, you'll get 1.03 BTC per day.  In a couple days when the difficulty jumps to ~400 million, you will only get 0.69 BTC per day.  And it'll only get worse as the difficulty continues to rise!

BTC is at $215.00 right now, and assuming it stays there (which it won't), and assuming you are mining 0.69 BTC per day (which will fall more and more), you'd have to mine for at least 34 days to break even, and if the BTC price drops, it'll be much longer.

If BTC dropped to $100, and assuming again that you were still somehow getting 0.69 BTC at the 400 million difficulty, which will rise, your break even time is now 72 days or longer.

And this does not take into account shipping costs or electricity costs.

And WHEN the difficulty rises, it'll be much longer.

Do you really want to be on pins and needles for 3 months or more, praying that your foolish purchase at least breaks even, much less makes a profit?

Save yourself the headache.

If you're that desperate to throw money away, PM me for my PayPal address.  

And I really had to LOL at how they list the Saturn version as the "more affordable" model.  50% of the hash rate for 60% of the price -- you're already losing money relative to buying the Jupiter version!

And this is not a rip on KNC specifically, this goes for any ASIC built by anyone.

Why not ? If we have money to loose ?

No more mining means no more Bitcoin.

[Trongersoll]

People who say don't mine should have to do full disclosure as to what their current hashrate is. Lots of miners may see discouraging others as a way to try and sustain the value of their mining endeavor.

[timk225]

Okay, here's my full disclosure:

I don't mine BitCoin, I'm not an idiot throwing hashpower at a futile cause with no hope of profit.  I mine LiteCoin.  And I just sold off most of my GPUs and will probably stop mining altogether soon and sit on my 200 LTC and wait for the price to rise.

My GPUs were pimping 4500 Khash in LTC recently, now I have about 1200 Khash still online.

I used to mine BTC back when the difficulty was about 11 million to 20 million, then I finally got CGMiner working and switched over to LTC.

Ouch, you only made 200 LTC from your whole mining operation?

[bitcoiner49er]

No more mining means no more Bitcoin.

If and when the hashrate levels off AND there are in-stock ASICs for reasonable prices, then the mining may make sense.

I don't know if this will ever happen though. Most ASIC producers have either been late and taken away mining profits, or been savvy and priced their equipment above possible mining profits. There have been a few that beat the rise in hash and delivered within a timeframe, but not many.
The ASIC producers can figure out what their chips hash and what to sell them for, or for how long to mine. Gone are the days of AMD cards made by a company that didn't really care about hashing and sold them in their performance tiers. Why would an ASIC manufacturer sell their chips for less than they can mine?

at least you do something good 

[BadAss.Sx]

In a couple days when the difficulty jumps to ~400 million

I can't wait for that day, because that means the Bitcoin will raise up again in worth. And more and more to come.

What a lovely world it is

[Kokomoka]

If you find it profitable to mine, then mine.

If you don't find it profitable, then don't mine.

The "invisible hand of the market" will take care of everything else.

[StewieG]

Well, maybe you should also take into consideration that, after you returned your investment, you have a machine worth a few thousand dollar which you can sell afterwards...

Difficulty has nothing to do with the price.
Why hasn't nobody understood this yet..

Just like an empty gold mine didn't raise the price of gold during the gold rush.

[os2sam]

If you find it profitable to mine, then mine.

If you don't find it profitable, then don't mine.

The "invisible hand of the market" will take care of everything else.

Since ROI is almost surely impossible, it's better to stay away from it for now.

Then feel free to stay away then.

Let the rest of us hash in peace.

So ignorant!
a 100 GH/s miner for example will not even be worth half it's current price in 6-12 months.
Maybe 1/10th of it's value.

Looks like we have fortune teller here, I love that, can you also predict the bitcoin price for next week? PM plz...
Just saying It is not all about the ROI when considering to buy a miner...

[Exdeus]

i paid 10 pink sheep for 550 Ghash and i will never see a ROI because my 550 Ghash mines BTC not pink sheep...

what do i say to that

baaaa!

[lajz99]

How many of these threads do we need?   

[balanghai]

That's where cex comes in handy at BTC0.082/Gh/s and deploys instantly as cloud miner, you have the option to sell the share so you both got the mining profit + the share which would then be a win+win situation when worst comes to worst.

You can check my sig for cex though.

Threads on what?  Stop mining, ROI or Pink Sheep?

Its a gamble, some people are thinking the difficulty would slow down

this is the best way to find out for yourself
