Title: Custom machine - 30Ghps Post by: ripkars on April 06, 2013, 05:16:16 PM Hi all,
Suppose one could build with more or less 8-10,000$ a 30Ghsps@3.5Kw mining rig. I'm not talking about custom ASICs; this is the actual cost of the rig, full stop. Do you think that this would be a valuable investment for a 18-24 month time frame, now? I know that there are simulators out there suggesting to build it immediately, but I would like experts' opinions given your understanding of the overall bitcoin system (market value, underlying deflation mechanism, Fed regulation (BCE coming, too?), forecast hash rate of the network, forecast difficulty and the like...) Thank you very much for sharing your point of view, ripkars Title: Re: Custom machine - 30Ghps Post by: allinvain on April 06, 2013, 06:03:49 PM None of those variables can be accurately predicted. Your guess is as good as anyone's and in the end it will still remain an educated gamble.

Beyond that point is anyone's guess. Title: Re: Custom machine - 30Ghps Post by: DPoS on April 06, 2013, 07:00:38 PM everyone would do that - probably pay $20k if you deliver today
but we all know you can't do that with a pile of modminers unless a miner dies and you buy from his grandmom garagesale Title: Re: Custom machine - 30Ghps Post by: ripkars on April 06, 2013, 07:01:32 PM I really wonder why people think it is necessary a custom ASIC to reach that throughput...

R&D don't happen over weekend like BFL suggests, anyone that would build this would not sell Avalon did since they were worried about a monopoly but only ghosts scare them to the finish line now they drink like kings Title: Re: Custom machine - 30Ghps Post by: ripkars on April 06, 2013, 07:08:25 PM everyone would do that - probably pay $20k if you deliver today but we all know you can't do that with a pile of modminers unless a miner dies and you buy from his grandmom garagesale Moreover, why should one sell this kind of machinery when his expected profit is much higher if s/he used that machinery for him/herself? I wonder the same for those how sell ASICs... is it related to the fact that if only one subject owns "all" the available bitcoins (theoretically speaking, of course) than their value might drop? ripkars Title: Re: Custom machine - 30Ghps Post by: relm9 on April 06, 2013, 07:28:29 PM everyone would do that - probably pay $20k if you deliver today but we all know you can't do that with a pile of modminers unless a miner dies and you buy from his grandmom garagesale Moreover, why should one sell this kind of machinery when his expected profit is much higher if s/he used that machinery for him/herself?

Thank you very much for sharing your point of view, ripkars it would break even within 2-3 months of use if you could get it running in the next month. Within a year you would see an additional 3000-15000 depending on your power costs and bitcoin value. how would you make the system though without ASICs? FPGA is the only way i know, and that would be more expensive wouldn't it? otherwise, 3500W would only run about 10GH of GPUs |
