Topic: Will a Sep/Oct KNC jupiter ever ROI? (Read 5305 times)

Nice to see people actually can make profit from buying mining equipment, so looks like KNC is after all the best company...

6 jupiters need approx. 4500 watt per hour = 108 000 watt per day = 3 240 000 per month.

that´s 3240 kwatt/h per month. 1 k/h cost about .25 cent (€) here.

they have been mining for 6 weeks now. so yeah, taking electricity charges into account they used approx. € 1200,- so far.

Wohoo, nice... just curious that did you take into account your electricity charges for the 93% return?

50% effiency is really bad, I would change the power supply if I were you...

i guess i am very lucky to have 93% return in btc and almost trippled in dollars with my jupiters.

THANKS KNC 

Just checking in with my Day 1 Jup.  Looks like i've gotten 37.5 BTC back from my original investment - I've been dollar cost averaging out, so the higher BTC to USD goes, the less BTC i need to sell

37.5 / 57 = 65% of my BTC investment has been returned.

Hindsight is 20/20, therefore I think you got it backwards my friend.  If purchased in dollars, you will ROI.  If purchased in BTC, you'd be better off keeping the BTC last June/July/Aug.  You would have made triple if you just kept the bitcions last summer.  You would make nothing if you just kept the dollars.

Yes, purchasing the bitcoins would have been better.  20/20.  Heck, I think purchasing them now would be better than getting into mining.  They could be 1000 in a year.  Who knows.  Yes, BFL sucks.  They're an expensive lottery ticket at this point.  I will be solo mining with mine soon.

1 Jupiter would cost ~60 bitcoins last summer.  If you had a day 1 order, you'd have made ~20 at this point.  Maybe 10-20 more before next couple dif changes.  So all in all better to not buy in bitcoin last summer, but buy in USD.

IMHO

it might ROI if purchased in Bitcoins depends on how the difficulty escalates, if purchased in dollars it will ROI, but it is also true that purchasing the Bitcoins would have been better investment.
buying a miner is a very high risk investments that can have high rewards, in case of loses they will not be very high, unless if you purchase from BFL and get the miner a year later.

ride this next difficulty level, then sell it used to some sucker a couple of days before next difficulty jump

Wall draw is always higher than actual used energy due to inefficiencies of the power supplies. 700W draw for 400W used doesn't seem beyond the realm of possibility.

I predict tears.

Haha, well. Works for me. I just use very conservative sequences. 

I want to reach 37 BTC to break even on the Jupiter, and then get to 55 to break even on other investments in mining, including 3 cloudhashing platinum contracts, and a BFL Little Single order -- that I could thankfully transfer over to 125 GH BFL hosting order (which should start in Feb).

Lolz, this has nothing to do with break-even. If you use 18BTC to gamble instead then you have 27 BTC which is more profit then jupiter...!!!

I don't think this qualifies as a Jupiter breaking even... lol

How'd you do that? Gamble that is?

I've mined with a Jupiter for two weeks now, made 12 BTC. Won 18 BTC gambling in the same period, so I'm almost break even!

Puppet +1.   

This is gonna be a fun ride...

Forever, of course not. But there is a reason growth is exponential.  its no coincidence the network hashrate since the first asics has perfectly followed an exponential curve; as almost always, if you see exponential growth there is a feedback loop. Every GH added to the network increases difficulty. Higher difficulty leads to lower mining profitability per GH, which leads to lower market prices per GH (until we approach vendors marginal profitability), which leads to more GH being added to the network.

So how long will it last? until we hit one of two constraints:
- vendors ability to deliver/deploy ever increasing numbers. If that happens growth will become linear rather than exponential.
- we approach marginal profitability, ie it costs more to produce/sell/deploy asic based miners than they are expected to earn in mining revenue over a reasonable time period (=market price or self mining opportunity).

We are very far way from the latter, literally at least one order of magnitude and potentially almost 2 orders of magnitude at todays BTC exchange rate.
As for the former, that one is hard to judge, but Josh boasting of 1000 units shipped in a day (if a similar volume can one day be achieved for Monarchs that could mean 10+ PH per month for BFL alone) and looking at the assembly plant that Hashfast contracted, I dont think widespread capacity constraints are likely to hit us anytime soon either.


So yeah, exponential growth will inevitably stop, but probably much later than you think. I dont see it happening before 100PH at least.

That is what they say about the USD...

Total paid, $14,597.80.  Plus 2 PSU's, 1 surge protector, new router, 50 ft ethernet cord.  I guess ~$15,130 total.  So I have a ways to go for ROI.  About 1/3 way there.  I'm hoarding btw.  US dollar gonna crash ya know.

Nice, how much did you pay both for?

2 Jupiters here.  First received Oct. 14th, 2nd on 17th.  Both in afternoon.  Mined 24BTC so far.

You want to be safe or accurate? One the one hand you do want to avoid making a foolish investment, but on the other hand you don't want to be too conservative in your calculations that you end up never buying a miner even when doing so could have made you a profit.

Actually, 130% is too low, increasing it to 150% would be safer.

Are you guys leaving the default settings on the genesis block calculator again?  130% per month growth - sure, that sustainable forever, no problem.

Yeah 20$ per GH is way too expensive now, you would not make it back with the current diff changes.

$20 is pretty expensive right now in the market, ASIC is going way cheaper...

Yeah $20+ per GH is pretty nuts.  Especially so for a BFL unit which at this point isn't even close to the best efficiency any more.

Jealous, I don't understand why people buy it from you for $8600...

Agreed -  Have you checked out ebay?  Man, the prices for used miners are off the hook.  People are not doing their calculations correctly...they are over paying per GHS.  BFL 60 GHS are going for 1300 - 1450 USD that's 21.7++ per GHS... that doesn't even make sense when you can buy it for .09 BTC  per GHS or under $20 per GHs on

If I recall correctly the pre-orders had a week to pay to remain in queue for Day1 delivery.  During that week the BTC cost for a Jupiter fluctuated between 55-65 (not including VAT or other costs).  I personally spent 59 BTC and remember being glad I didn't buy a day or 2 before as the cost was a few BTC higher.

I'm fairly certain the customers that will win out the best were the ones that paid 55BTC, mined for a week or 2, then sold the machine for a decent price.

in our case the magic number is also 55 btc since at time of purchase of our jupiters bitcoin was at 100,- € and price tag was 5500,- €. interesting to read how much other day 1 owners have mined in the first few days, since knc hosting had a bad start.

we are happy with our purchase.

Well he still have like few more months to mine before difficulty go insanely high. He might roi.

You're almost break even in dollars, but nowhere close to break even if you had bought btc with that 6995.
That is to say you could have bought about 60 btc with that $6995 then sold about 30 of them at 210 and recouped your original investment (and been ahead 30 btc). So, that should be your reference point for break-even.

ROI should be measured in terms of bitcoins that would have been needed at the time of purchase (~60) and how many bitcoins you have generated. So, it sounds like you're not even halfway there.

Good for you! Dude, sounds like you made a good return =)

Day 1 Jupiter received on October 7th.  (Purchased for $7k)  Mined for 11 days @ 525 Ghs and then sold on Ebay (local pickup) for $8600.   

Jupiters are the best out there and I'm very happy with KNC.  (I have two additional Jupiters hosted by KNC which I'll let ride for 7 months!)

In case you want to hear how the "Day 2" Jupiter's are doing:

First Jupiter:
Shipped from Sweden Thursday October 10th @ 3:30 am
Received (West Coast U.S.) Monday October 14th @ 3:45 pm
I was out of town, didn't get it hashing until Wednesday morning October 16th.

Second Jupiter:
Shipped from Sweden Monday October 14th @ 8 am
Received (West Coast U.S.) Thursday October 17th @ 4:30 pm
Starting hashing the same day it was received (Thursday evening).

Mining on the Bitminter pool.

So far, for the two Jupiter's combined, I've only received 17.5 BTC total.

At current prices, I've only made back about 22% of the purchase price (not counting power supply cost, electricity cost, shipping).

(Currently using the 0.97 firmware getting about 540 GH/s on each.)

6995.-$ but i sold 22BTC on 210$, so im almost break even.

your cheques are in the mail :-)

No way it will ROI... Nothing sold these days seems to.

How much did you pay for it?

That's pretty crazy...still wish i bought it =)

I made also 25,7 BTC since 4th of October(day1) with my Jupiter.

Hardly ROI, only the first few days of the KNC shipment would ROI..

That's amazing dude!  Wish I ordered a first day machine.

Yes for Sept shipment and no for Oct shipment...

When did you receive it and on what pool you mine?

So far, i've mined ~25.5 bitcoins with my day 1 jupiter.  After the next difficulty jump i'll be making about .7 a day.  I expect to make around 58 BTC with the device.  After which, maybe i'll solo mine and see if i get lucky

By ROI I mean: "mine the amount of BTC that could have been bought directly on day of payment for the jupiter, at least".

It should be about 55BTC to mine at least.

Seems impossible to me. What do you  think?
