I'm pretty sure there are a lot more "7500 coins on one HD in the trash" stories.  I wouldn't be surprised if somebody lost 10K or 20K coins and won't admit it simply because then others know he/she probably has a lot more Tongue

Yeah only 2 are related to the protocol itself, the rest is stupid human.

The answer depends on which version of the universe/mutliverse you believe in.  If you believe in a multiverse it will be in the trillions of years.  If you believe in a singular universe the is slowing its expansion and will collapse in on itself and recycle, the never.  If you believe in inflation (negative gravity) it would also be trillions of years.  Better spread those BTC around to multiple wallets!  Shocked

Considering the missiles move about 1 mile per second, there are very few techniques other than direct visualization that a satellite could use to detect a launch.  It it could utilize doppler or ground based radar it could track an object without direct visualization.

The path to hell is paved with good intentions.  Obama espoused his good intentions of having everybody covered for a low cost.  The reality is this cannot happen, especially when all other insurance in the US is for catastrophes - not day to day expenses.  Health insurance shouldn't cover well child visits or annual checkups - those the patient should be paying for.... but that would require the patient be responsible for their own fricking body - something I see in less than 20% of my patients now.
1206  Other / Politics & Society / Re: Can Aspirin treat breast cancer? Why aren't we trying to find out? on: July 23, 2014, 04:49:37 AM
Being a phsycian who is really disgruntled with the current state of medicine I will throw in my 2 satoshi:

The study is retrospective and not the classical double blind model.  The women diagnosed as dying from the cancer had to have a cause of death directly cited as being attributed to the cancer.  If you take aspirin and you're healthy the biggest risk is bleeding.  This risk goes up several fold for cancer patients, and goes up through the roof for anybody on radiation or chemo due to the internal scarring and the decreased platelet counts.

Aspirin is great as an anti-inflammatory.  The problem with say "breast cancer" is that there are many different types.  Aspirin, or rather anti-inflammatory medications should be a mainstay treatment in cancer regimens.  Ultimately the patient would have to trust their oncologist to make a recommendation as to how to treat their individual cancer.

The article may not appreciate big pharm (and to be honest I'm disgusted with their direct to patient advertising) but the big pharm in the US are pretty much the only ones making the last 9 new chemo agents that did not exist 4 years ago.

Ultimately the cure for cancer will not be chemo mediators but rather cellular attack techniques which go back to molecular biology rather than biochemistry.

When the AG is completely unwilling to investigate what happened because he feels there was no impropriety there is no chance in hell anybody will be going to jail.  The statute of limitations will expire for a majority of these crimes and WHEN Hillary gets elected the favor of no reprisal will get passed on.

I laughed when watching Stars Wars at how simply evil the Sith Lord was portrayed as - sadly we're not that far off in this country.  No integrity at all from the DOJ.  How can people respect a cop if we can't respect the people at the top of the pyramid?
1208  Other / Beginners & Help / Re: Mining on: July 23, 2014, 04:16:43 AM
Hi, i read about mining (CPU, Hardware, GPU ...). But can you help me to start mining??? What i need to start??

Mining is no longer profitable.

If you do not believe the statement above, remember to do extensive research and homework before you spend a great deal of money buying or building miners.

It is still profitable if you have free electricity but going ASIC is much better..

Even with free electricity most of the ASICs for sale will result in a net loss:  BFL Monarch ultimate looser, KNC Jupiter loser, Spoondoolies SP30 loser, Rockminer R3 loser, BTCGarden loser.  The only one that is current that might make a profit is the Antminer S3 and it's is sold out for that reason - it's actually reasonably priced.

Using a long password is by far the best security.

More important that the entropy (length) of a password is the exclusivity of the passphrase.  If you use the same password of JO98h%$&hkCD43SD on every website you visit, the hacker simply needs to hack into any retail website you used the passphrase on and now he has your email and passphrase.

You can use crappy passwords on most every site, for you Bitcoins use a passphrase you don't use anywhere else.
1210  Other / Beginners & Help / Re: Mining on: July 23, 2014, 02:35:22 AM
Mining was reasonable way to acquire coins until ASICs came along in 2013.  Back then exchanges were very unreliable (MtGox was a failure since day 1) and buying a selling coins was very difficult (even without the AML restrictions).  These days it's much easier to buy coins and most likely that is the best way to acquire them as most mining ventures prove to be unprofitable for end users.

So either work for coins directly or use you disposable income to buy coins - it's easier and more profitable than mining for them.
1211  Bitcoin / Mining speculation / Re: cex.io mining thoughts on: July 23, 2014, 02:22:21 AM
Hey guys,

Just wondering what your thoughts were on mining at cex.io? Iv read a lot of negative feedback about it and not much positive.

From my experience, its not the worse.
 Yes the fees are ridiculous, but ive made a profit so far.
From 0.5 btc, ive managed to make 1.9 btc trading, however, that took 3weeks and was a huge amount of effort
it's from trading
and many of us not a good trader like you
seriously, 0.5 BTC -> 1.9 BTC in 3 weeks is good
did you use bot?

No bot, i dont trust them, but i was on the site for most of the day, even at work, for three weeks. Was very tedious and would not recommend!


Congrats on the profit but that is the issue...I guess if you have no life and no family, and don't want any other hobbies, you can be profitable with trading it.  But you didn't even get too much and think about the obsession it took to make that much.  You're better off getting something more "hands off" so you can enjoy your life a little!

While numerically he didn't risk that much for most Westerners he did triple his money and that is very much an accomplishment.  I doubt more than 5% of all people trading could accomplish that.  Of course if he tried that with 20BTC he would not be able to replicate that since the swings from his purchase would move the market too much.

I think he got very lucky with some skill - I would suggest he trade on an exchange and skip the CEX.IO middleman.
1212  Bitcoin / Mining speculation / Re: Mining equipment, what i need to make 0.2btc a day? on: July 23, 2014, 02:16:48 AM
You will need 17 Antminer S3's.

https://www.bitmaintech.com/productDetail.htm?pid=00020140704023505485N5SxDMkW0693

.725 BTC each so 12.325 BTC or $7641.50 US.

You will also need 6 1300W PSU's and you will need 6.2KW of available power.

You will also need box fans to remove the heat and you will need 17 ethernet cables and a 24 port ethernet hub.

You will also need a rack to put all the miners on and some zip ties.

Do you have a room or garage with 3 X 30amp 220V breakers?

Also you will probably need to double this by the end of the year to keep making .2BTC a day.

Investing around 10,000$ USD is fine with me, however do you think it's worth it?

To continue mining 0.2BTC a day you would need to constantly acquire more equipment every difficulty increase.  Assuming a simple 10% per jump, you would need to be spending $1000 every 12 to keep at 0.2BTC/day.

Is it worth it - well if you have free power and lots of space yes it can be very profitable.  If the space is not free or you are paying more than $0.07/KWH you will probably lose money.
1213  Bitcoin / Mining speculation / Re: Dell : Possible plans to enter mining sector on: July 23, 2014, 02:12:29 AM
Dell has a professional Data Center Solutions team currently working on cloud computing and optimizing hyperscale data centers, tools that could no doubt position Dell to enter or serve the "now booming industrial bitcoin mining space."
That's completely irrelevant. Bitcoin mining is completely different from data center operation. In Bitcoin mining, there's very little data traffic, either within the data center or to the outside world. All those key-testers have nothing to communicate except when they're being loaded or when they get a hit. Real data center operation is dominated by network issues.

Also, in Bitcoin mining, the hardware is profitable for maybe 6 months.

Yes but Dell has
-long term contracts with foundries and the clout to get mass runs of something like a new 20nm design
-cheap Texas power
- a household name.  Imagine how easy it would be for Dell to sell a million cheap miners on eBay just from the Dell name. Throw in some stupid Ashton Kutcher ad and it's a done deal (would help decentralization though).
1214  Bitcoin / Mining speculation / Re: New to Bitcoin need rig for college (don't pay electricity fee) on: July 23, 2014, 02:08:26 AM
Do some research before you melt your dorm's power plug. U don't wanna overload it..

Simple power fuse check will say most importan things, since i doubt hes thinking about something serious.
But OP, keep in ming that there is also noise, heat , and i doubt that "no fee" policy is as shallow as you think, if they found out what ure doing, im pretty safe they will stop you.


When I went to college I stayed in one of the nicer dorms but some of the older dorms had no AC and the wiring in there was definitely lacking.  One of my friends actually melted the wiring with a 2 cubic foot microwave - don't assume dorms have proper modern 12guage wiring and arc fault sockets.
1215  Bitcoin / Mining / Re: Super frustrated!!! Mining in the summer, yay. on: July 23, 2014, 01:29:38 AM
Well post on here the city you're in and maybe somebody would be willing to host them.  You could also sell them in the marketplace here, which when combined with escrow, is a lot safer than using eBay/Paypal.  I figure people on eBay would buy your gear, mine for 25 days, and then say it's broken and ask for a refund and make you pay for shipping both ways - that's how eBay works.

Again if your power costs are above $0.10 it may be worth it if you do buy new S3s to have them hosted in WA state.  Sure you have to pay for hosting but then you don't have to pay for electricity and the wife is happy - it may be a better solution.
1216  Bitcoin / Mining / Re: Super frustrated!!! Mining in the summer, yay. on: July 22, 2014, 05:57:29 PM
You can't put them in a storage unit.  They would have the heat trapped and if they went up in smoke you may be liable for all the losses.

There's an option called colocation - basically you give the miners to somebody and they host them and pay electricity and housing - you give them a set amount per month or for a contracted time.  This is an good option if you feel you need to keep mining and they miners are pretty new (ie they will generate a lot more coin).  If they're near the end of life you should just try to find a local buyer and cut your losses.  A $20k divorce is more expensive than $4k mining loss.

For colocation there's a thread in this forum listing options - lots of people in WA state since power is cheap there.  Shipping to there will cost you so it may not be worth it.

As noted above you could try to move the miners to the window and force the hot air out - look at the mining rig pictures thread and get some ideas.
1217  Bitcoin / Mining / Re: Super frustrated!!! Mining in the summer, yay. on: July 22, 2014, 09:41:02 AM
Find a way to reduce the heat, more air conditioner might be the way but it also depends on your electricity charges..

He's already blowing fuses on the circuit as it is.  Either he has to run more extension cords for 240V or has to do something other than AC.
1218  Bitcoin / Mining / Re: btc guild unlucky of late? on: July 22, 2014, 09:29:07 AM
variance!! do I win a prize?  Grin

Ah... regarding this hearsay about a large hasher withholding blocks, I was not aware of that but as I said at the beginning of this thread I was starting to wonder if it was something like that going on.

Don't get me wrong, I love the pool's site, best interface around and very clear, plus the operators at least appear to be very transparent.  It was just that terrible luck they had a few days ago that left me thinking WTF??

Well the pool was running close to 105.9% luck if I recall for their 3 month average before the sh*t hit the fan in May (when the withholding attack started supposedly).  At that time nobody complained that the pool might be cheating, although people did allege that in the past back in 2011.

So when it's up almost 7% (106-99) nobody complains.  When it's down 7% something is wrong.

The withholding attack is not hearsay BTW, the person was identified.  But he states his custom version of CGMiner was at fault.  The thing is it could have happened at any pool, and some pools don't even bother with the nice stats. Too bad the withholding didn't go on at ghash.io lol.  The same "attack" also occurred on Eligius and the guy is asking for payment which Eligius held once they discovered the problem.  You can check the pools subforum for this info.

Eleuthria might not be eligible for sainthood but he's one of the best pool ops around.
1219  Bitcoin / Mining / Re: Super frustrated!!! Mining in the summer, yay. on: July 22, 2014, 09:06:48 AM
J_Dubbs, I know how it is.  My wife was the same way.  It was more of an issue about time rather than heat in my case since GPU miners were not as stable as ASICs.

My wife makes 6 digits and yet she nagged me to sell Bitcoin at $5 in 2012 which I sold almost 1k coin - so imagine how I feel.

At the end of the day, I can always make more money as long as I have my health but I can't get buy a new wife.  Afterall the reason I want to make $ is for my family and not so much myself.

You might just have to bite the bullet and have them relocated to some cheap hosting site.
1220  Bitcoin / Mining speculation / Re: cex.io mining thoughts on: July 22, 2014, 08:58:58 AM
I'm going to repeat what I said in the other thread because these threads are basically asking the same question - how do I choose the best loser:

If you buy Bitcoin right now with $40k USD you get 64.9BTC instantly which you can sell at any time (what you if need the $ for a cancer diagnosis).

If you spend $40K on cloud mining you will mine less than 64.9BTC in the next year.  Even if you had a 5 year contract you would probably not mine more than 45BTC if even that.

The mining company will have made somewhere between 10 and 25BTC off of you with a 5 year contract if they keep their promise (which they will either keep as profit or use to make their own farm to compete with the hashes they sold you making your hashes worth even less).  If they go bankrupt like bASIC, Hashfast, or many of the other Bitcoin scams then you'll lose something closer to the original 64.9BTC.

So in summation nobody should be mining with cloud mining honestly since it is only lending towards centralization.  If you want to support the network buy a miner and mine knowing you're probably going to be at a loss but will be supporting Bitcoin.  If you want to become richer in fiat, buy and hold... or in the case of the OP buy and trade, but do at an exchange.

There's no reason to trade on a cloud mining platform - you're just adding one more variable - the chance the company might run away.  Of course an exchange might close but which do you think is more likely to happen?
