Any more GB's in the near future?
Here you go, I've re-opened this one.
Topic: CLOSED (Read 5839 times)
CLOSED this group buy.
price changed to BTC1.08/unit due to the shipping costs.
Updated pricing to BTC1.05
Argh, I so wish I could get in on this.
Just send the payment, post here your tx id.
Hello??? This GB open or not?

I re-opened the group buy as we're waiting for bicer transaction to confirm...
Hopefully I'm not too late:
name: JakeTri
No. Units: 8
Payment sent: 16.24 BTC
Payment address: 195PjivKhFrYw3h1eCuWCnZTLr45YVYu1Y
Pickup: Scarborough
I'll send you a PM with hash for my signature using 195PjivKhFrYw3h1eCuWCnZTLr45YVYu1Y address.

Hopefully I'm not too late, here's the details:
name: melmo
No. Units: 10
Payment sent: 20.3 BTC
Payment address: 13qt66nn1ZdcHNuvC2edhnLD7emwiE3b8g

Thanks melmo for your order. I have updated the OP. Please send me a hash of your user name using 13qt66nn1ZdcHNuvC2edhnLD7emwiE3b8g address.
Once all transactions clear I'll place an order.
Did you get my PM? I see 5 confirmations... hopefully that last one doesn't take too long

Thank you bicer. I have verified your address. Just waiting for 6 confirmations...
This group is officially closed for new orders. I have emailed friedcat to get the payment info and to place our order.
If anyone of you who placed orders with this group buy want to order more, now is the chance to do it.
Once I get payment address from friedcat, I'll place our order immediately so if you want to get more you can still do it.

This should conclude # of outstanding units. https://blockchain.info/tx/0c1c0bf64c9e1fc2c07c4d7ef110397c2a8063f132fe525e8612a806dc638839

I am glad that we are back to talking about ROI and not about personal attacks.
I had to lookup what ROI means in Wikipedia. Thanks to you, I got educated and made some calculations:
1 Eruptor for 2.03BTC will generate 0.338378 BTC a month according to online calculators
Here is the source of your error.
You assume that the difficulty level is going to remain constant over the course of the next 6 months. This assumption, however, is incorrect. As we have seen in the last little while, difficulty level has been increasing exponentially. They will continue to do so due to the number of ASICs that are going to be released.
What you are going to get is a geometric sum with ratio < 1, and only the first term will be 0.338378 / 2 = 0.169189 (first two weeks). All other terms are going to be exponentially decreasing. As you know, the sum of a geometric series with ratio q is 1/(1-q).
So, if you run 1 Eruptor infinitely long, then your total revenue is: 0.169189/(1-q).
In order for buyers to be able to ever recover 2.03 BTC, one needs
0.169189/(1-q) > 2.03
Thus,
0.083344335 = 0.169189/(2.03) > 1-q
In other words,
q > 0.91665567 and 1/q < 1.0909222.
This means that the difficulty does not increase by more than 9.09% at each retarget.
Can you remind me by how many percents the difficulty increased in the last few retargets?

I appreciate that Canary has upped his Canadian order restriction to 15+ units for his group buys. I'm hoping that will encourage more Canadians, especially in the GTA, to buy here. I want my stick!
Neither companies are delivering significant products....Avalon seems to be becoming as sketchy as BFL...possibly worse, at least BFL is shipping Jalapeno's at this point. Avalon has dried up.
(Some of these ASIC's may be delivered at some point but until we see them shipping much of anything I'm not concerned about them.)

Taking for account that difficulty will increase, I will give it 7 months
As my newly acquired friend, could you please check my calculations and if possible dampen my enthusiasm because I am eager to buy more of those babies.

you may want to change that 7 for a higher number.
how much higher depends on avalon, bfl, etc
In any normal investment a 15% ROI is already outstanding...and to get 15% you are already outside of normal "safe" investments.
Indeed. And part of a legitimate discussion about hardware is ROI.
Thank you Dr Lukas for your last remark, let’s put poverty issues aside and focus on your point.
You must have an accounting or banking background.
I had to lookup what ROI means in Wikipedia. Thanks to you, I got educated and made some calculations:
1 Eruptor for 2.03BTC will generate 0.338378 BTC a month according to online calculators
The cost will be recovered in 6 month = 2.03/0.338378
Taking for account that difficulty will increase, I will give it 7 months
Remaining 5 months is 5*0.338378 = 1.69 BTC profit
(take away allowance for difficulty increase) profit 1.5BTC
I do not count electricity cost because it is negligible: 2.5W x 8760h = 21.9kWh/year
And here is Wikipedia:
return on investment (%) = Net profit / Investment × 100
1.5 / 2.03 x 100 = 73.89%
I cannot see any investment on any stock, bond or mutual fund giving such a yield.
