And this is exactly why regulators are going to argue Bitcoin has no consumer protection, unlike the major credit card companies. The people who paid these guys in Bitcoin can easily get screwed over.

The same can be said of cash in any form, be it BTC or $.  Bitcoin is just a currency - and no currency I know of has built-in consumer protection.

what econ class did you take?  that's not ROI that's simply getting your money, back, breaking even.
Breaking even means 100% ROI, no? Enlighten me.

In Bitcoin land yes for some reason people started using it that way and it stuck.  For the entire rest of the planet ... no.

ROI is return ON investment.  breaking even is 0% ROI.  Losing money (like buying a 100 BTC rig which only produces 60 BTC before it goes into the trash heap) would be a negative ROI.
wikipedia disagrees with you, sir.

No it doesn't.  If net profit is negative, ROI is negative.

Quote
return on investment (%) = (Net profit / Investment) × 100

gold/euro/chickens all have value.  I know chickens were meant as a joke but still laws on books about them.  Bitcoin is not a official currency in US, and since virtual will be interesting to see how it goes.

Are you hiring a lawyer who specializes in anything, or law firm with multiple?  What type of lawyer accepted the case?



US courts disagree with you:

Yes, there are paragraphs there now....   Grin

Ohhhhh.... LOL, guess I reviewed the edited version Smiley  Yeah, that would be painful to scan...

Paragraphs are your friend...  td;dr  (too dense; didn't read)

Sorry bro, done, was typing on the train home.

Geez, I count 8 paragraphs in what looks like 5-600 words there.  I guess you need to either type very short sentences, or make a new paragraph for each one these days - or risk being ignored by those afflicted by the ADHD epidemic.  I'm not worried much about offending any of them though, as they all quit reading after the first sentence Wink

We all should really stop with this preorder shit. Its nothing else then free loan to the company. If company has a solid plan worth risking, then go to the bank and ask for loan.
In earlier blackarrow explanation I have noticed that he speaks of btc price implying it will rose among the difficulty. That was adsressed milion of times; then we are better of just buying and holding bitcoins at today market price.

Same port for either proxy, 8332

Also if it matters: BFG is given -u worker.name -p pass and the blade is using worker.name2 same password.

I also tried them both being the same with no luck.

I would think that should work.  BFGMiner doesn't care about the username or password the blade is using, as long as each blade has a unique username.  Is it possible that the other proxy is not really releasing port 8332?  I would think that BFGMiner would complain if it couldn't open the port, but I don't know what else might be wrong here.

Trying to use BFG miner as a getwork proxy to see how it compares to other options. Can't get blades to connect.. must be doing something wrong. I read the documentation and all it says is to run with the --http-port option. Here's how I've tried it:

bfgminer -o url:port -u workername -p password --http-port xxxx

this loads up just fine. the blade is setup to point to the system running bfgminer. bfg never sees a connection. if i close bfg and load the other proxy, the blade connects. This is the win32 version.

What am I doing wrong?

Maybe a stupid question, but are the blades set to connect to the port you specified in '--http-port xxxx', or the default port for your other proxy?

although I don't expect they will be keeping it for long.

why not?

Well, there seems to be a lot of people on here with legal action on their minds.  I expect that they will have some success in their suits.

I personally do not have a dog in this fight anymore.  My investment in Terrahash equipment was via a 3rd party, and I got my refund long ago.
830  Bitcoin / Hardware / Re: Off-Topic on: September 20, 2013, 11:31:21 PM
truth is, although Im worried about my investment, Im worried about the founders of TH as well.  you can all be as cold about money as you want, but there is probably equal chance that this lack of communication could have been caused by personal tragedy

Most likely the same personal economic tragedy that is affecting most of the people in this thread...


you guys are all a bunch of fucking idiots if you believe that, TH pulled at least half a mil $ out of bitcoin/wire payments alone. What have they actually used the money for? a couple steel boxes, handful of half working boards, oh and a few boxes of resistors/wires that cost pennies.  They never invested this money in anything, it doesnt take a genius to figure this out, and if you are really that dense just look at the chips that got sent in - if they were really ready just missing the avalon shipment, those chips should be turned around in days instead of silence.  How else would they expect to make 40k chips worth of orders.

they scammed your money and is not giving it back, all the bullshit about hosting and refund after 3 month etc.. is exactly that...bs.

Like watching a train wreck, i just cant turn away.  Are people really this fucking stupid, if you are out of 4 figures i would be filing for legal action weeks ago.

If you thought I was expressing sympathy for Terrahash, then you are the idiot.  The point is that most of the people on this thread got plowed by the economic tragedy that is Yifu, and Terrahash (and Yifu) is the only one that made bank out of it, although I don't expect they will be keeping it for long.

...it's almost like I didn't say all of this half an hour ago in this very thread...

Sorry, I actually meant to reply to Puppet's post.  Clicked the wrong one.  I also had not read the whole, thread.  My bad.

We're right though Wink

833  Bitcoin / Hardware / Re: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s on: September 20, 2013, 07:56:22 PM
Point is that its not vendors pricing thats to blame for the lack of profitability. LIke I said, they can put any price on it per TH they want, 5x lower than today, and it would still not be profitable because miners would just buy 5x more and still  over invest. Once they stop doing that, asic prices will drop further (further increasing difficulty). There is no solution, its inherent to the nature of the mining market and asics.

Great point! Wish I'd thought of it... Huh

I think the market has been severely distorted by pre-sales.  Miners have been willing to pay more for gear because they have been paying for it in a time frame when it looked like a good investment - but by the time they actually get the gear, the ROI is nada.  Miners will soon  (out of necessity, if not common sense) come to realize that this preorder thing ain't working - and vendors will have to have gear in-hand to sell it.  THEN, miners will be able to make realistic decisions about what prices make sense.

Thanks guys Smiley


Every time I save the config from BFGMiner I have to go in and edit out all these multiples of the temp-* values, because BFGMiner (which created the file) says there are too many values, and won't start. Huh
835  Bitcoin / Mining software (miners) / Re: BFGMiner 3.2.1: modular ASIC/FPGA, GBT, Strtm, RPC, Lnx/OpnWrt/PPA/W64, BE Blade on: September 20, 2013, 06:31:19 PM
How would this terminal code be properly put into the config file?
sudo bfgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u <user> -p <Password> -S all

And is the config file named bfgminer.conf?

Running the sudo command I just listed then I try to save out to conf file from the terminal window running bfgMiner but it does not seem to work...

That would be because sudo executes as root and would be saving it under root's directory.  Try just running the bfgminer command without using sudo.

That doesn't sound correct.  Saving the config from BFGMiner saves it in the current directory, right?  Using sudo does not change the current directory, and it also does not change the environment - so even if it save to $HOME, it would still be your home directory, not root's.

No I haven't worked an electronics assembly line, nor have I managed an electronics-production line, nor have I done large scale electronics design. I have overseen mass distribution though. I have designed circuitry. These guys make it a business to do the same, and from what hints they've dropped, they appear to have gone the route I suspect.

Again as mentioned previously, their profit margin is well over 50%, likely 70% for these units. They're not too worried about their cost. They already have the boards, and are tested. This eliminates production time as a factor for delivery. They stated the only power connections would be PCIE. This hints there will be on board regulation.

So whether I've worked or designed as you propose is moot, especially if my understanding of their hints is correct.

You said:


So, there will be PCIE-8 connectors for 12vdc to the main board but does the Beaglebone take 5vdc?  Is there a 12v-5v switching down converter onboard or will the Beaglebone always require a separate 5vdc supply?  I can see how one might first apply the 5vdc, login, configure the miner, then fire up the 12vdc but an onboard converter would preclude two PSUs given the device can already have been configured.

You're questioning whether an engineering team with proven designs is going to forget to put a voltage regulator in place so a daughterboard can handle lower voltages?

Seriously?


I'm just pointing out that there are two equally valid engineering perspectives here, and KNC could go either way - but your tone in the above quote suggests that there is not.


The possibility can certainly go either way -- the probability is that they likely have an on board regulator. Perhaps that helps explain my text-based tone better.

If I am wrong, I will certainly tip my hat your way.

It's not clear to me what you are basing your 'probability' estimate on.  I can't claim to know what KNC will do, but my experience suggests that they would actually be MUCH more likely to go for less cost/complexity vs. adding a 'might be nice' feature.

In either case, you were not justified in addressing Soy's post as if it was ridiculous.  It wasn't. And that was why I replied.

The question came to mind seeing the Beaglebone PSU connector.  About your tone....

I wasn't trying to be rude, I just look at it differently. My take is to simplify things, they would have an onboard power source for the BB.

Another valid engineering perspective would be 'to make it less expensively, let's not have an onboard power source for the BB.'


The cost of a DC:DC regulator, especially by the reel, is on the order of pennies, or fractions of a penny depending on what you get. They already said the only power connections to be made will be PCIE. They're going with a KIS method for this. Plugging up an extra power cord adds complexity and time, especially for rig-testing. I'd wager they're willing to spend the .005 cents on the PCB components for onboard power.

It's obvious you have never worked on a design for mass production.  Eliminating a DC-DC regulator and associated circuitry would typically be considered a massive win for manufacturing.

When I compile bfgminer on ubuntu and run configure the getwork proxy shows disabled.  All the dependencies are installed.  Any idea why its not working.  

You probably just need to install libmicrohttpd-dev.  If it's installed, the support should be enabled by default.

EDIT: If you DO have it installed, you should look through the configure log and see why it's failing to enable it.


It shows enabled.  Now when I go to start bfgminer I get error

./bfgminer: error while loading shared libraries: libmicrohttpd.so.10: cannot open shared object file: No such file or directory

It appears that it is installed in a place where the linker can't find it,  if it is indeed installed anywhere.  It's not clear to me how it could be found by the build, but not found at run-time.

On my system, it is installed as /usr/lib/i386-linux-gnu/libmicrohttpd.so.10.
