25  Bitcoin / Mining / Re: what's the most efficient mining hardware available? (bachelor thesis) on: January 17, 2014, 08:48:09 PM
Hi guys,

no I'm not another newbie whos thinking to get rich by mining.
I know that mining is not profitable at all due to rising difficulty caused by "mining-noobs", losing a lot of their money.

In fact I think theres acutally blowing up some kind of mining bubble. When people realise they make no profit and sell all there mining hardware the bubble could explode and rise the btc prise down. But thats just a theory.

I'm writing a bachelor thesis about bitcoin and in one chapter I will analyze if its possible to make a profit by mining.



A bit off topic but in the vein of academic integrity, since this is for a thesis. You "know" mining is not profitable but you haven't analyzed profitability yet, and want people to give you lead ins to do so.
It's one thing to hypothesize it will not be profitable, but fore knowledge is dangerous.

Doubling every month, except for all the months where this is not true.
27  Bitcoin / Mining speculation / Re: hash rate mania on: January 13, 2014, 07:03:47 PM
Yeah by the time even the first neptune's come out they probably won't make their money back other than by just selling the device to another sucker. The next difficulty jump is 32% -_-

Show your math.

Thankee for a bit of breakdown, and the D&T chart helped. I was curious how people had fared, looks like a lot of the usual, many promises, some come through, many do not, but still, pushing 3 PH... yowza. And there goes the BTC price exploding again, which I'm sure will make things even more interesting.
29  Bitcoin / Hardware / Re: Playing ASIC catchup on: October 18, 2013, 09:48:35 PM
I hope your reply will serve as a succinct demonstration of why I'd like a quick headlines, and why it's not unreasonable to ask, rather than read 866 pages (of just 1 thread).
30  Bitcoin / Hardware / Playing ASIC catchup on: October 18, 2013, 09:45:22 PM
So, I started a new job a few months ago, and basically had to fall off the face of the bitcoin world, I have a little more time now and check in to see a lot of changes, but sadly a few months in bitcoin world is like a few centuries elsewhere, so I was wondering if anyone could give me the highlights on where things stand since I last checked in (around june/july)?

Last I knew, Avalon had shipped batches 1 and some of 2, with batch 3 to be on the nearest horizon. There were a billion and 1 chips ordered in 10k batches to be delivered in August.
BFL had just started shipping a few drips of jalapenos, KNCMiner was just opening up for business to deliver in September as the new hot kid on the block, and that's about all I think.

Now I see over 2 petahash of power online, so someone must have delivered, can someone fill me in?

Thanks.

4 days later, bitcoin price unchanged. Good lesson in not panicking.
32  Bitcoin / Mining speculation / Re: Wanna buy KNCMiner? Prediction Data -> Time vs Hash Rate vs Difficulty Data set on: June 29, 2013, 12:19:43 AM
Depressing stats.

I ordered a KNC yesterday with the option to pick it up in Stockholm (I live in London) -- which, hopefully hopefully, can be done when I'm in town for an international security conference in late September.

It's looking a lot like ASIC mining is a game that everyone is losing together.

That said -- there is one qualification on a positive note: with the rise of ASIC mining and the total hashing power of the network and increase in difficulty, there is also a countervailing trend that may be a source of slight optimism: if everyone is moving to ASIC, then the FPGA and GPU rigs are bowing out, and switching to other coins -- that could mean a drop of about 100 TH/s of the network, counteracting the 400-600 Th/s increase that ASIC will bring about come fall. One can hope.



GPUs probably make up only about 40TH/sec of the network. FPGAs don't really have any reason to bow out, they're not that much less efficient than ASICs. By the time they have to drop out, the amount of hashing power they represent won't even be noticed.
33  Bitcoin / Mining speculation / Re: Wanna buy KNCMiner? Prediction Data -> Time vs Hash Rate vs Difficulty Data set on: June 28, 2013, 04:35:47 AM
So basically, you'd need a 600GH/sec machine at the $7000 price point shipping in september to break even?

No?
34  Bitcoin / Mining speculation / Re: How many THs deployed by KnCminer this year? on: June 24, 2013, 02:50:12 AM
The grey number is the units' SKU (Stock Keeping Unit). The identifier companies use for products to keep track of what the hell people are actually ordering is.

I've not been paying much attention lately, has KNC put out numbers on power usage? Don't see it on the homepage. 350GH/sec would be like 1400W at 4W/GH already (close to a full 15A 104v breaker).

I also don't expect even if 1787 were somehow the "batch" they were producing that they'd run out.

Maximum of 1000W for the Jupiter and 500W for the Saturn is what they have on their website.

Ah I see it on the homepage now, thanks. That just makes me even more skeptical but we shall see. Good times if they can deliver.
35  Bitcoin / Mining / Re: Should I sell me 5ghz asic or mine with it? on: June 22, 2013, 08:14:21 PM
If it was known that a jala would mine less than 25 btc in its lifetime, would anyne buy one for 25 btc?

Buying one is a bet that it will, selling one is a bet that it won't. But no one knows.

My personal feeling is that either way, its a good idea to have a guaranteed 20x return, which you can then decide to keep or attempt to parlay into increased hashig power at a later date. But that's just me.
36  Bitcoin / Mining speculation / Re: I know it's too late, but aren't we shooting ourselves in foot by buying ASIC? on: June 22, 2013, 12:28:00 AM
No, it's not really right, for a number of reasons.

How do you define common good?

ASIC miners secure the network against... someone making ASIC miners and destroying/overthrowing the network (what is happening now on a limited scale). That seems like a common good.

There is not much 'common good' in the way the hashrate is currently distributed, something on the order of 60% of the hashing power is controlled by 5-10% of miners. (There are posts with better estimations that I don't want to look for now).

ASIC manufacturers benefitting from developing a bitcoin exclusive product is bad how exactly? Currently AMD is making some extra pocket money from bitcoin, is that somehow better for everyone? I personally prefer to see industrious individuals with know-how and energy succeed from bitcoin interest.
In fact, a demonstration of a bitcoin exclusive industry being built from the ground up, can be potentially leveraged into a good case for more businesses building around bitcoin. Another common good.

If at the end of the day, the mining landscape is the same as it is today, except that people are using ASICs instead of GPUs, I don't see that as a problem, except for those few foolish ones who thought dropping $30,000 on an early miner was a sound investment. But that is an individuals own decision to make, and doesn't really relate to the common good in my view.
37  Bitcoin / Mining / Re: Solo each rig or pool on: June 22, 2013, 12:19:24 AM
Probabilities work out instead of getting .01 bitcoin all the time, you get 25 every once and a while.

How can you calculate the probabilities. I have 300 Mhash and I was thinking its not enough to solo mine on btc but probably enough to solo mine on some altcoins.

I still use http://www.alloscomp.com/bitcoin/old_calculator.php to calculate probability

300MH/sec would have a 50% probability of finding a block after hashing continuously for 2221 days, 5 hours, 54 minutes (roughly 6 years) at current difficulty.
38  Bitcoin / Mining / Re: Those who have died while waiting for BFL to ship on: June 21, 2013, 06:54:52 PM
Some famous people who have died while people were waiting for BFL to deliver:

Edith Bunker from All in the Family (Jean Stapleton)
James Gandolfini (The Sopranos)
Dick Trickle (no lie, that's a real name, he's a nascar driver)
Joyce Brothers (psychologist and comedian)
Jeff Hanneman (founder of SLAYER)
Chris Kelly (of Kriss Kross, gonna make you... jump jump!)
Roger Ebert (Film critic, joined his good buddy Gene Siskel)

and I'm sure many more. It's been a long sad time these BFL non-delivery months.
39  Bitcoin / Mining / Re: A case study in entry-level mining on: June 21, 2013, 03:21:20 AM
I'm not saying coinlenders is a scam, so don't misinterpret me that way. It certainly could be possible for you to be running a legitimate and thriving business, I simply said beware. Bitcoin is an irreversible transaction, and so deposits are a huge leap of faith. Akin to sending someone a bunch of cash through Western Union. If you don't imagine yourself being comfortable doing that, why would you do it with bitcoin?

That said, no risk, no reward, perhaps it's a good investment. Just make sure to do your homework, protect yourself as much as you can, and be prepared for both sides of the risk-reward continuum.

As to what you should do OP, I would not presume to tell you what to do, but if you think that you might not break-even on the units, I would certainly find something like http://www.ebay.com/itm/BitCoin-ASICMINER-USB-BLOCK-ERUPTER-333MHash-ASIC-Black-IN-HAND-READY-TO-SHIP-/300921840079?pt=LH_DefaultDomain_0&hash=item461056e1cf an appealing alternative.

As I said in my original post though, I personally would ride the hobbyist enjoyment train. If you enjoy tinkering and displaying and toying with the hardware, that's great, and if you take a small loss, it's not the end of the world.  Smiley

25% wow, where would that be.    Ive never heard of virtual savings, we are far down the rabbit hole now.    If this is correct and other financial innovations, there is hope yet

https://www.coinlenders.com/interest

Dawg, I tried to warn you before about the ASICs, but you had already ordered them, so I didn't really want to get into it too much, but seriously, BE-WARE of this coinlenders nonsense. Anyone offering 25% APR is suspect.

Anyone whose website was registered March-22-2013, set to expire March-22-2014 is more suspect.
Any "business" that is run by "whoisguard" is suspect (imho).

Put all those together and you get... super suspicious.

Maybe you've done your due dilligence, I dunno, but I would really hate for this to all end as the tragic story of a guy who got scammed from A-to-Z by the bitcoin world.
