[SOLD OUT] TerraMiner IV – 2TH/s (February Batch)

[tludwig]

OMG! Isn't that the idea, that we make several group buy's, in order to invest the money in btc? Here in germany the power is very expensive. At the moment I'm mining, but the ROI is getting lower and lower. I don't have the money for big miners with less power consumption. So, I invest in this and other group buy's and hope that Hashcesar84 and the other guys have future business plans than only for one time.

Cheers,

Thomas

hi, how i can buy shares?

[mattboldfield]

Their isn't any money to be made in bitcoin mining anymore you fuckwits!
Carry on you suckers, no wonder this world is fucked when its full of nothing but dimwits.
Im retarded lol!
Haha, Hey mate I didn't scammed out of 12K did I?

L-O-S-E-R!!!!!!! Justify it anyway you want, $2000 coin price, it will arrive on time, difficulty wont be that bad!
Denial is the first stage of recovery!
Good luck with it mate! We all gotta learn the hard way sometimes!
I pity the fool!

[BorisAlt]

Wow, this is getting funny.

Did he really accuse that other dude to be me?

Seriously funny shit right here 😝 And we are not even close to getting HW yet.

Episode #1. I knew popcorn would come in handy.

Mattboldfield, don't get angry, man. Find a humor in this fucked up comedy. The only people who should not find it funny are those who already paid. And even they could enjoy this theater, just think about it as price of admission to the show.

The story is simple:

The boy buys magic beans. Magic beans turn out to be a dud. The boy realizes that beans are not going to grow. He goes on the internet to offset his loss. He says so explicitly in his post #56 that he realized magic beans weren't gonna sprout and he is offloading the burden on other nice people of bitcointalk. A wise man (yes, very humble me), points out that, listen boy, these ain't the magic beans, what are we trying to grow here, eh? The boy get antsy and says he doesn't want to share magic beans with the wise man.

An angry man comes along and tells the boy to stuff his magic beans up his arse. The boy gets even angrier  and will try to save his investment using his power of persuasion.

I am looking forwaward to episode #2. Thank you.

hi, how i can buy shares?

Instructions are in the first post.

Just make sure not to ask any questions about what happens with your money.

[Hashcesar84]

Shares list has been update, thanks for buying.

[mattboldfield]

Nice analogy BorisAlt, or is that my other personality???
Post was as hilarious as a bitcoin dreamer! Well you've got the popcorn, so I went to the kiosk and brought back choctops. Here you go mate! (passes choctop.)
Got angry because I hate people being fucked over, but im ok now, Ive had my vent and am ready for the show.
Let the classics roll, 5,4,3 shhhh 2, 1...........

Oh, I totally understand! I got angry early on but once I realized that the boy with magic beans has no clue it became the comedy that I can now enjoy.

Hello,

let go of your worries, just 3 days and we are in February, miners could arrive in any moment and I will set up it immediatly.

In cointerra's forum they talk about a delay of less of 1 month in January's batch and they told they will send an addictional terraminer of 2TH/s (March batch) for any miner ordered for January. Theoretically Febrary batch will be on time, if not, I'm sure that they will give me 2 addictional miners probably April Batch. I will share both with customers as percentage writen in the topic.

I'm convinced that, if delivery will be on time, this group buy will get a good ROI and easy.

Regards

Almost NOTHING in this post is true.

How the hell could they deliver February orders BEFORE January?  January orders are at best, WEEKS out.  You will not see a Feb order until April and even that is being optimistic.

[eightcylinders]

Can the haters please leave Hashceaser84 alone?  He has been nothing but honest.  Maybe the investment will turn shitty, maybe not; but he is offering a pre-order in the most on-time system around and it seems pretty fair for those of us who are willing to take a chance.

FWIW, January shipments have begun on time TODAY so all of you predicting April can eat your words:

http://cointerra.com/pr-cointerra-begins-shipment-terraminer-iv-worlds-fastest-bitcoin-miner/

That is pretty good reason to believe that February shipments will be one time too.  Cointerra is ahead of everyone else.

Of course its still a risk, but a February or early March delivery and this miner should return ROI.  Assuming that difficulty continues to increase at the current rate of 1.32 every 2 weeks, and BTC price stays constant at about 850/$US, the difficult in one month will be 3.288e9 and the ROI will be 200% after only 90 days:

CoinTerra Ships First Terahash Bitcoin Mining Rig!

[eightcylinders]

Of course its still a risk, but a February or early March delivery and this miner should return ROI.  Assuming that difficulty continues to increase at the current rate of 1.32 every 2 weeks, and BTC price stays constant at about 850/$US, the difficult in one month will be 3.288e9 and the ROI will be 200% after only 90 days:

I just saw the cointerra blog where they say that the early shipping units will <only> achieve 1.64-1.72 Th/s.  Also, my method above was slightly flawed because I computed ROI for someone buying the Terrahasher and operating it themselves, versus what is offered here which is a share of 2 Terrahashers with a management fee... so correcting my calculations:

Cost of 100 shares: .65 BTC ($552.5 at 850/US$)
Percentage ownership: 2.5% (of 2 machine total hashing power per prior clarification by OP)
Computing power of 100 shares: .025 * 3,400,000 Mh/s (assuming these will average 1.7 Th/s each) = 85 Gh/s
Net computing power of 100 shares adjusted for 2.5% fee: 85 - (.025 * 85) = 82.875 Gh/s
Cost of 1 Gh/s: .65 / 82.875 = .007843 BTC per Gh/s (net of the 2.5% fee)

The 90 day ROI under this scenario, hashing starting 30 days from now, for 100 shares is still a pretty decent $180.95 (a 34.4% return in 120 days - better than I can do with any other investment right now):

For these values ...

     MHash : 82875.0
     Difficulty : 3.822E9
     Days : 90
     Change : 1.32
     Watt : 0.0
     Electricity cost (USD/kwh) : 0.0
     USD/BTC rate : 850.0

Also, on the downside, if you add on 14 days of difficulty increases (to middle of March when refunds are promised if no delivery) you get a worst case.  This would mean that starting difficulty on March 14 is 5.045e9, and the ROI on a 100 share purchase has to be stretched out to 180 days to get a break-even (slightly positive return of about $56, which is nearly a 10% return on a 180 day investment of $552.50):

I just saw the cointerra blog where they say that the early shipping units will <only> achieve 1.64-1.72 Th/s.  Also, my method above was slightly flawed because I computed ROI for someone buying the Terrahasher and operating it themselves, versus what is offered here which is a share of 2 Terrahashers with a management fee... so correcting my calculations:

Cost of 100 shares: .65 BTC ($552.5 at 850/US$)
Percentage ownership: 2.5% (of 2 machine total hashing power per prior clarification by OP)
Computing power of 100 shares: .025 * 3,400,000 Mh/s (assuming these will average 1.7 Th/s each) = 85 Gh/s
Net computing power of 100 shares adjusted for 2.5% fee: 85 - (.025 * 85) = 82.875 Gh/s
Cost of 1 Gh/s: .65 / 82.875 = .007843 BTC per Gh/s (net of the 2.5% fee)

The 90 day ROI under this scenario, hashing starting 30 days from now, for 100 shares is still a pretty decent $180.95 (a 34.4% return in 120 days - better than I can do with any other investment right now):

For these values ...

     Change : 1.32
     Watt : 0.0

Also, on the downside, if you add on 14 days of difficulty increases (to middle of March when refunds are promised if no delivery) you get a worst case.  This would mean that starting difficulty on March 14 is 5.045e9, and the ROI on a 100 share purchase has to be stretched out to 180 days to get a break-even (slightly positive return of about $56, which is nearly a 10% return on a 180 day investment of $552.50):

On the website of cointerra they say they ship the machines under 2Th/s. (http://cointerra.com/update-production-news-janfeb-batch-customer-offer/)
However, customers can recieve a coupon code of 15% for a next order, as quoted below:

"For January or February batch retail customers who wish to receive their TerraMiner order in the currently-shipping specification we will offer a 15% discount coupon* redeemable against their next retail hardware order placed at the CoinTerra website store.  If a January or February batch retail customer chooses to accept their order as-is they will automatically receive this coupon. "

If Hashcesar84 accepts this coupon, how will the price per share be affected? Or will we recieve more shares so the total amount of hashes/s per share is the same.

If they will give me I will accept the coupon, but I don't know if I'm gonna buy more from cointerra's shop in next months. I hope they will give me an additional terraminer for another batch as they are doing with people who bought January batch, in this case I will share it. I didn't understand very well if this refund's coupon cancel what they told previously about additional miner.

Now I can't find where they talk about additional miner, but I will look for it and I will post the link asap. I'm sure I reed it anywhere!

Probably they are gonna delivery on time and it will be better for everyone.

this is what I think about our ROI / increasing month 80% and I think is fulsome.

remove 3 btc for difficulty's increasing during month. (it is fulsome)

Effective return: BTC45.72  (minimum)

than if we keep mine BTC we're gonna lose moneys

Nov-14 435171 5408  BTC-0.56
Dec-14 783307 9735  BTC-0.62


We'll gonna mine others alt and any advice is welcome, I don't know yet which other crypto currencies is more profitable to mine with a terraminer.
I will learn more about next months.

remember when you try to calculate we are in 30 January, if you put an increase month 80% it should start from the month after. Not from the day after tomorrow!

If you look at difficulty it is gonna growing less rapidly of what everybody expected.
