Name coin 0.0115!! Imo time 1-2 months and we'll switch to mine only altcoins Wink

Will be nice to get the roi on the expensive shares of the pre-Bitfunder era

( or even here http://www.coinwarz.com/cryptocurrency/?sha256HashRate=1000.00&sha256Power=500.00&sha256PowerCost=0.1000&scryptHashRate=750&scryptPower=350.00&scryptPowerCost=0.4000&sha256Check=false&scryptCheck=true )

You linked to a scrypt comparison.. We can only mine sha256 coins (that are not merged with bitcoin like namecoin):

Didn't find anything within this thread. But there is https://www.multipool.us/ which can mine the most profitable SHA-256 and Scrypt coin per hour.

The problem with multipool is that ppl manipulate the prices of altcoins in order to make certain coins "look" profitable while they are not. It's great if you are GPU mining and have a lot of spare time to actually check profitability, but not something you want to do with 14+TH atm. Also don't forget that you can't sell newly minted coins. They need to mature first which can take a few hours up to a whole day depending on the coin.

Could we eventually put these to mine alt-coins?

Can you guys tell me the total monthly cost to have these runing (housing + energy + ?? )?

Yes we can, but so far no SHA-256 altcoin has proven to have a long term higher profitability than Bitcoin. That might of course change in the future..
The cost for housing and energy (what we pay the datacenter) is 200eur/miner/month paid weekly. Thats why hosting costs have been going down every week

If Blastbob & Tyrion70 were to engage in another GB, would the value of our Addiction shares be diluted i.e. currently each share is worth approx 28.23MH/s (I think it's more than this right?) so if they bought Neptunes would current share value essentially be worth 1/6 of what they were as the hashing power of a neptune is approximately 6x more than a Jupiter? In other words would the new Neptune buyers shares receive 6x as many shares as I have for my equivalent Jupiter GB, or I misunderstanding this completely?

Question is kinda moot since we won't buy Neptunes due to the price/delivery date combination but we might find some hardware in the future somewhere so this is how we would do it:
Currently we have 27*12400 shares (334800 total). We have little over 14TH so thats 41.8MH per share ( Cheesy

).

Say we buy a Neptune which does 3TH (actual number). Then we could issue 3.000.000 (MH) / 41.8 == 71770 shares per miner. That would mean we'd had a total hashrate of 17TH (14+3) with 406570 shares (334800 + 71770). That would keep the hashrate per share on 17.000.000 / 406570 == 41.8 MH / share Cheesy

So no dilution..

So far the questions Cheesy

As for the Neptunes.. We think one of the great things of our groupbuy was the fact that we (Blastbob and myself) were (a big) part of the group. It wouldn't feel right for us to start a groupbuy on Neptunes if we wouldn't invest (heavily) in them ourselves. As it stands Blastbob and myself don't think that those miners are a good investment from a BTC perspective. While the ROI calculation we posted above was pretty negative (with 110%/month), I remember clearly when we started this groupbuy that we thought an average 16% increase of difficulty between June 5th and now was highly unlikely.. I just looked it up, in the period between June 5th and delivery we've seen one diff change below 16%.... on average it was almost 29%. So even though the last one was "only" 20% and the next one will be around 16% that in no way guarantees we will continue to get those percentages the following months.
Lastly we find delivery in Q1/Q2 way to wide.. We bought the Jupiters with a September delivery in mind.. They produced their first Jupiter September 30th 23:50. Even though we feel KnC did a marvelous job and we can't complain about getting a 500+ device while we bought a 350 device, we fear Q1/Q2 will end up being June 30th 2014. Now thats pretty far away

Cheers,
