i don't believe so. as i recall, the last bounty on osama's head was either 20 or 40 (i think it was doubled in there somewhere) million dollars. didn't work, did it? in any case, good riddance. |

Really? In a whole year? I have a proposal for you...
I've got 10BTC says the network is at or above triple today's hashrate (712.08 Gh/s) at Bitcoin Watch, by April 27, 2012.
Bet?
No. This is still gambling, and I don't gamble neither do i.  |

But why? What's your reasoning?
Exactly the same reasoning as you, but I just can't see total power tripling in the next year. I hope I'm wrong though. Really? In a whole year? I have a proposal for you... I've got 10BTC says the network is at or above triple today's hashrate (712.08 Gh/s) at Bitcoin Watch, by April 27, 2012. Bet? In the other thread I even ran the trend assuming only 5% starting now (wholly unreasonable) and the guy who dropped $3000 + $151/month on his mining rig still wouldn't break even.
I agree, buying expensive hardware specifically for bitcoin mining is a bit ridiculous. [/quote] Perhaps. It just depends on what you believe the exchange rate will be in the future. |

it's 28 April 2011, mtgox is trading at ~1.75 usd/btc. I've been mining with a 3 GHz CPU for ~24 hours now. My client says it has 8 connections, 120606 blocks, and 1 transaction (my 0.05 from the faucet). How many alpaca socks can I buy?
save your 0.05BTC for twenty years and you'll be able to buy a small alpaca factory. with several guys named Al, to do your packing... |

The same 5850 is $40 cheaper on newegg with rebate. The coolers on those cards are nice but they don't vent out of the case, they just pass they heat issue from the card to the case. The reference ones are better. i've kinda gotten out of the habit of even checking NewEgg, since i found MicroCenter. and the convenience is worth the occasional higher price. i note that MicroCenter's ads include NewEgg pricing... you're right about reference cards though - i spent an extra $50 on my latest mining case. more fans than carter has little liver pills... |

5850s are not as efficient as 5870s. Less stream processors is my guess as to why. You can get four 5870s on one PSU, no problem.
5850s are significantly cheaper to buy though. You would save money on the MB if you went with less 5870's. For me the 5870 is the sweet spot. I would love to have a 5970 but I never run into them cheap. Where can you get 5870's for a reasonable price though? Everywhere I'm finding them they're 300+ $249 with a $50 rebate: http://www.microcenter.com/single_product_results.phtml?product_id=0331363i just picked up a couple. and the cheapest 5850s are only twenty bucks less: http://www.microcenter.com/single_product_results.phtml?product_id=0346683MicroCenter is better than NewEgg - and i have one just down the road... |

I'd say there are 4 variables not 1. Namely:
- exchange rate
- difficulty
- capital costs i.e. equipment etc..
- recurring costs i.e. electrcity, rent, wages etc...
You're right, vladimir, of course. Perhaps I should have said "the non-calculable variable is the only one that matters..." |
|

There's only one variable that has any meaning. Exchange rate: short-term, mid-term, and long-term.
Everybody has a different answer for that. And nobody's got a lock on what it's really going to be.
I see no difference at all between Bitcoin miners, and the old '49ers at their gold sluices. Some may be more cynical than others - but we're all optimists, betting on the come.
So what, if your mining costs are $2.00/BTC - when you're planning on holding for two years and you think the exchange rate will go up to $10.00? Under that assumption, you're laughing all the way to the bank.

It seems like you've over-spec'ed some components - for a dedicated miner. But I see problems with heat and power. Three (three, right?) of those 6990s running full-bore will chew up at least 1200 Watts - but your PS is only a 1250. Not groovy. Also, the case you've chosen only has fan controls for the front fans. Once you get your power supply situation sorted out, you're going to have about 1500 Watts of heat to dissipate. I have my doubts that the Antec case - unmodified - will handle that. You'll definitely want the optional side fan - but don't get the Antec: get a good aftermarket fan with a speed control, and replace the rear fans with controllable fans as well. With three of those 6990s, you're probably going to be thinking about waterblock cooling pretty quick - or running with an open case and a bunch of jury-rigged external fans. Don't even think about adding a fourth card (there's room...) until you've got three under control. |

Why such fixation on intel chips? AMD semprons work just fine and costs are lower.
I agree. The sempron would be a better way to go (plus 45 W TDP), but I'm having a hard time finding a suitably cheap board that has 2+ PCIE slots with good spacing. It seems I can find tons of those MicroATX and MiniATX boards, but I'm looking for an ATX sized one. Do you have any recommendations Vladimir? If I may, I can recommend the MSI 870A-G54. 2 PCIeX16 slots with proper spacing, and a PCIex1. It does support Sempron ( http://www.msi.com/product/mb/870A-G54.html#?div=CPUSupport ). |

That's comparable to seeing a hot chick in a bar and opening with the pickup line, "I guess you don't put out?". It's pretty much certain to attract an impolite response.
You're quite right - and this really shouldn't be /. Apparently, if on this forum, her response would be to pull out a .45 and say: "I'll put you out, baby..." Which brings up some line or another I heard once, about politeness and a gun... |

Those things are all coming.
On Saturday, in fact.
Basically, the Bitcoin for Android wallet app. That will be (effectively) the same thing.
It will work off the network as well as on the network.
But this proposal is all about the hyper - Low Tech.... paper money.
How can I find the best private company that can print me some of my own paper currency (or "credit receipts", technically)...?
What company prints those other private paper currencies, like BerkShares and Detroit Bucks, etc...?
straight paper can be counterfeited - in fact, so can gay paper.  Bitcoin cannot be counterfeited. and just about everybody on earth has a phone - soon, everybody will. and integrating a tiny, purpose-based printer into a phone isn't terribly difficult. they already exist. all it has to print out is QR code. there. that's your paper money: little squares of print-on-demand QR code. |

economists understand as much about the economy as MBAs understand about business.

Well yeah, or a smartcard. That would be nice, but AFAIK, noone has ever compiled bitcoind for such a device.
BSD runs on *anything* - or so they're fond of saying...  |
|
|

On a side note: I was just thinking the other night... Perhaps the Bitcoin client is creating an artificial ceiling of 1.00 USD parity because of it's default 0.01 minimum denominations..?
that's an interesting thought. perception is everything. |

hmmm...
what about this:
a little coin-shaped USB thumbdrive-type gadget, with just enough storage for a couple of blocks and an implementation of SHA-256? and a tiny CPU of course.
you carry it around loaded with whatever - say, 100 BTC - on a part of your blockchain that has been reserved, or 'frozen', from participating in normal transactions. but those blocks are known to be frozen across the network. you give it to somebody, they plug it into their phone (or netbook or iPad) to verify that those frozen block(s) have adequate BTC for the transaction being contemplated.
then, once they've verified it against the blockchain residing on their device, you plug it into *your* device, authorize the transfer of X-number of BTC (which changes your frozen blockchain for later upload), they plug it back into their device and the transfer is completed. their blockchain updates, removing the freeze from that quantity of BTC known to the network as having been frozen. for somebody with whom you've established trust, the first step (them plugging it in to verify) could easily be eliminated.
cash! ...and p2p off the internet.

Who are the merchants that have the most use for bitcoin unique features? That is an easy answer: Those who want
to purchase or sell illegal goods and services. My prediction is, whether you like it or not (pretty sure most of you like it), the bulk of the bitcoin economy with be in illegal goods and
services in the near future.
i do believe i must respectfully disagree. here's an interesting bit of history: back when the internet was text-only in UNIX - long before the www, http, or mouse trails - some bright human figured out how to get pictures on the 'net. what happened? well, two things - and pretty much simultaneously: porn... and booksellers. bookselling is one of the last of the maverick occupations - but quite legal to pursue. books are, in their own way, like Bitcoin: little bits of untraceable wealth. art auctions will follow, and jewelry. the underground economy is not really all about illegal substances and transactions, although we are kin (note that i am a bookman). the underground (and quasi-underground) economy is always first to see the potential in these things. by the way - any book collectors on this forum?  |
