Sul forum in inglese sono arrivato a 20 card ordinate. Quindi da adesso riesco a fare 0.24BTC/card

Ohy bella gente, mi fate sentire in colpa cosi  Smiley
Sono rientrato adesso...
Sto andando male, altro che bene... per tutta la mattinata ho minato con metà potenza perchè un sistema è andato in blocco per cause ancora da indagare.

Astronavi a parte, quelli che fanno paura sono i soliti americani, col fatto che la corrente costa la metà, ne approfittano abbondantemente  Angry

Noi possiamo stare in coda.... tralasciando bestie montate da 40-50GH/s, su btcmine ho notato che ce uno che cammina sui 15GH ed un altro sui 10... lenti i ragazzi  Roll Eyes


A parte la corrente  per fare 15GH devi aver investito una fortuna (minimo 15K$).
Bisognerebbe affittare una server farm in Bulgaria (0,088€/KWh per la fascia domestica- 0,07

Right, combined we have a very significant processing power. Which consists of what? 50,000 GPus, 100k GPUs at best..   Give me $100M and I'll quadruple current hashing rate at minimum. What's $100M for a country? - it's like 100 dollar bill to me and you if not less

No you don't: maybe you need 2  times that for build and mantain it for 6 months. To run a mining farm of  30.000 superpumped 3x6990 rigs (that will do 3X the actual hash power) you need at least 500 full time employees (in 6 month at least 30 million $), (Godaddy has 1500 technical employees for 60.000 servers)
There are energy bill to pay even if is a governative installation (at least 20Million $ for 6 month paying 0,05$/KWh). Add a good 10 million $ of network infrastructure and connectivity (I don't calculate a redundant 10GBit connection to internet assuming a govern can obtain it almost for free) . UPS and backup generator will cost you another 50-60 million $ (we are talkin of a 90MW, a small power plant - a similar one, highly ecological,  built 4-5 years ago costs about 200M$). The cooler must be really efficient to work in a similar environment (one rig produce 1,5KW of heat, like a powerful server with 8CPU and 24 disks. But no server farm hosts 30.000 of that servers for what I know ): at least 30M$.   
The 30.000 rigs wil cost at least 40 million $ (I've considered a 20%-25% less than the wholesaler prices, probably lower than the price you can have buying a bigger stock directly from producers, and with no assembly cost).
Total: 200M$, plus the building, the connectivity, the security (both from hackers and physical assaults). If you're in hurry to build it you can easily double the costs.
Overall if a govern wants  to kill bitcoin, it's still a small investment to do.

sounds great ercolinux!


And I hope people like my free service. If there is anything you dislike or need regarding WalletBit speak up!

 WalletBit is really a nice idea. If you could accept SEPA transfers (it can be done only using a Euro as currency, but I've found that  is usable to make transfer to Denmark, as lon as the amount is Euro ) it would be fantastic (no fees or cost in transaction for that  for the whole eurozone), otherwise 105DKK is around 14€: that make bank deposit not much usable.
1067  Bitcoin / Project Development / Re: WalletBit.com Translation Help on: July 24, 2011, 06:43:33 AM
I can help you translating it to Italian (I think in a couple of day I can give you the translated file).
1068  Economy / Goods / Re: [WTS] - laser engraved bitcoin cards [preorder] on: July 23, 2011, 09:27:24 PM
Could I get 10 cards with no hole punched, black background/white text, and 1C3qpakjET1wAFEkZKTdZrpRxCAo5nZVcw shipped to the US?

Where should I sent the payment to?

Sure you can  Smiley
Shipment costs (air mail) is 0.45BTC for 10 cards
As explained before in the post, I'll sent you the payment address as soon as the cards are ready, I enclose a photo of them too to make sure I don't try to scam you. We will have 2 weeks of summer holiday here from 1st of August, so I'll expect to be ready to ship from 22-23 August.
If you eventually prefer to pay before is possible too, but due to the fact that the final price can be lower than the one you actually pay, I'll refund you the difference.
1069  Economy / Speculation / Re: Bitcoin and Velocity of Money on: July 23, 2011, 01:25:58 PM
Velocity of bitcoin will remain low for long time: you can achieve a high velocity when the whole system uses the same currency but when, as for BTC, you've only a small subset of the economy using that you probably reach a maximum of 5-10/yr. As now we are probably near 1.2-1.5/yr.
1070  Economy / Goods / Re: [WTS] - laser engraved bitcoin cards [preorder] on: July 22, 2011, 06:26:45 PM

But if the order is for an card engraved with a personal address, then what about order cancellation? The seller can't be expected to eat the cost of a useless engraved card because the customer changed his mind and didn't pay. If I were ordering (I'm not), I would be perfectly happy to pay up front. Amazon expects you to give your credit card details up front when you make any order, even if the card is only debited when the order is shipped.

Yes, I know that I took a risk accepting order  this way, but I want believe that no one fraud for a small amount like that.
1071  Economy / Goods / Re: [WTS] - laser engraved bitcoin cards [preorder] on: July 22, 2011, 08:49:06 AM
I'd like to pay now.  Ordering now and paying in BTC in August is like you short-selling BTC.

No is not: price in BTC will be rearranged if there is a increase/decrease of BTC value (I can cover a +/-5% of fluctuaction around 13.9$/BTC). But if you prefer to pay now there is no problem at all.

What he means is that he might owe you 0.5btc (for example) now, but if the market crashes to $3 when he needs to pay you in a couple of months, he will owe you like 3btc.


I've got the point, is a double way risk because if he owe me 0.5BTC and market jumps to 30$ he will pay me only 0.2BTC.

If someone prefers to pay me now no problem at all: and  I'll refund the BTC in excess according to the price table I've posted if number of ordered cards allow to reach a lower price before shipments.

Good  Cheesy

We have reached the minum for the order. I hope to obtain some little discount from the supplier
Who is interested can PM me the bitcoin address that want to be engraved on as well as the mail address to which I've to delivery the cards. As soon as the cards are ready I'll send you back a picture of the cards with the BTC total so you can make the payment.
The cards will be ready for the shipment from 23-24 August (there are 3 weeks of summer holiday from next week).
1074  Economy / Goods / Re: [WTS] - laser engraved bitcoin cards [preorder] on: July 21, 2011, 09:30:13 PM
These look really neat to use for in-person transactions. If you don't mind saying, how do you make these laser cut cards?

Thanks,
sega01
The p2p use is exactly the use I've imagined.
For the building process: the card are made of a sandwich of 2 plastic layer, the support is thicker and white, the other layer is a black film on it, (the gold-silver version have black support and a brushed metallic layer). The laser "burn" away the upper layer engraving the qr-code, the logo and the writings. Actually that's not visible in the picture but alle the white is some 1/100th of mm engraved: it's a nice feel when you touch it.

Way to raise suspicion and stir up the market. Grin

Seriously though... who holds 850k bitcoins in their wallets in the first place??

At the moment the richest wallet is 424242.434242 (a rich boy with a good sense of humor Grin )
Here is the daily updated list of top 100  (all are over 6300BTC)

http://bitcoinreport.appspot.com/

What you see is a total of the transctions in a block (and as explained there are a lot of movemets from a 24000BTC wallet)

mi tornerebbe molto utile una stat riguardante i btc/worker

giusto x sapere se un worker sta minando in attivo o no.

imho sarebbe la stat + utile in assoluto e nessuna pool la ha.

dovrebbe calcolarsi così

Code:
(BTC/Blocco * Shares/Blocco) / Shares Worker

Se si sta minando in negativo significa che è entrato qualcuno'altro di nuovo nella pool che ha aumentato i Mhashes totali e, di conseguenza, fa diminuire il totale compenso degli altri utenti, ma aiuta a trovare prima il blocco. Se succede questo sloggarsi significherebbe una diminuzione ancora più pesante del compenso... non trovo l'utilità a sapere questo dato... anzi incita a lasciare la pool

beh in teoria trovato un blocco si passa al successivo.

il fatto di trovare blocchi + velocemente é un plus della pool (si ricevono pagamenti + piccoli ma in tempo minore).

ricevere 1 BTC da 1 blocco o 0.1 BTC da 10 blocchi é la stessa roba...


Non è proprio uguale al 100% se non puoi minare 24/24 -7/7. I pool veloci in quel caso possono essere leggermente più convenienti a causa della varianza (calcola che ci sono pool che risolvono 1 blocco all'ora in media ma vista la varianza alcuni blocchi saltano in "-3minuti, un pool lento ci mette sempre almeno qualche giorno): se imbatti in 2-3 blocchi veloci quando sei connesso  guadagni di più e d'altra parte un blocco sfigato (tipo quelli da 5-6milioni di share che escono ogni tanto ) blocca un pool veloce per 3-4 ore al massimo, uno lento ci mette anche 1-2 mesi a farlo.
Detto questo io sto qui anche se ho solo poco più di 200MHash/s (sperando sempre che si aggiunga qualche GHash/s di potenza Wink )

There is a guy who is splitting is usin a  24755.1225BTC address in a lot of 20-50BTC transactions: maybe some transaction is for trade but maybe is only for security reason (even if the value put on every address is not round: 28.7 - 31.34 - 41.47 and so...)
1078  Economy / Speculation / Re: If 272.000 people today each owned 25 Btc bitcoins would be out of supply. on: July 20, 2011, 10:05:02 AM
I think the statistic for real money is:

5% of the world's population owns 95% of the world's money.

Last stats I've read (referring to 2000-2001) tolds: 1% owns 40% of total, 10% owns 85%, but the worst thing is that the lower 50% of population own 1% of wealth.
I think that we are not so far for the BTC economy: I think that there could be 1% that holds 40-50% of the BTC ( as you can see here http://bitcoinreport.blogspot.com/2011/02/latest-bitcoin-top-100-rich-list.html 2 account alone holds near 10% of total BTC - near 5million $ and 1,6million $ at current change),  a 10-15% holds the 80%. But a good 30-40% has less than 1% of bitcoins.
1079  Bitcoin / Bitcoin Discussion / Re: BitWatch - A mining pool watch app for Symbian made in Qt on: July 20, 2011, 09:19:44 AM
I'm currently developing a new app that has a better UI and eWallet and Mt. Gox trade exchange information compatibility. (I am also planning to make it open-source) It should supersede this app once it's done.
That's fantastic :-) I just find out that there is no ewallet for symbian. And if you do it opensource is even better.

I can however easily add any pool to this app if the pool has a JSON API, just PM me with details and I'll add it in.

You've a PM
1080  Other / CPU/GPU Bitcoin mining hardware / Re: Can my PSU handle it? on: July 19, 2011, 09:52:23 PM

EDIT:  I've also just realised that my PSU caters for dual graphics cards (ie, it has 2 PCIE cables, both with dual plugs at the end).   I'm not sure how I'd add a 3rd card as I'd need another 2 PCIE plugs for them...   can you get molex to PCIE adapters or something?

Doing some math at the moment you're draining about 450-500W from 12V line. Adding a 180-190W for the 5850 O.C. leaves you with only 40/60W on 12V rails. Not a good idea (disks use 12V too)
Using molex adapter is OK as long you try to use short cables and good quality ones: 190W are 16A, if the cables you use thick wires you can damage them, or ever start a fire.
