since KNC miner died, where to find firmware ? its not listed in OP.

 I just now uploaded the second last update kncminer-1.00.bin file which I believe is for either version of the miner (they used different VRMs after October).  I might have a copy of the tuning version still but a) it will be specific to the septmember version and b) I'll have to look later because it's bed time. Let me know if you need a different version as I'm sure I saved a few.

Maybe I'm just stupid but what's the meaning of collateral when you're offering one for a loan?

 It's not that you're stupid; you're simply ignorant of the meaning of the word.  This is repairable whereas "stupid" probably isn't.

 Why not go back to the thread where you learned how to sign the message with that address and see if it twigs your memory as to which program or service you used to get the address.

i am really getting tired of seeing all this talk about China and bitcoin. everyone should start talking about the other 195 countries instead of focusing on what people are doing in China when it comes to bitcoin.

 We can talk in terms of trading volume instead but we'd still have a big red elephant in the room that everyone wants to ignore.

A total of 1,953 schoolchildren joined hands for the largest ring-a-ring-o'roses at The People's Park, Waterford, Ireland, on 20 April 2004. The song was repeated for six and a half minutes, with everyone falling down and getting up in unison.

6509  Bitcoin / Bitcoin Discussion / Re: Very Small Transactions Unconfirmed for Days ?? on: January 10, 2017, 01:53:56 PM
...

Thank your for your comments guys.  My transactions from 4 days ago were confirmed, finally, today.  I then went on to send out three more very small trx to get my BTC out of the blockchain.info app for iPhone, here are two of the trx numbers (the third went to an app (iPad) I have elsewhere, I do not have that info handy):

9d90d0170110364270ac161e59d9de03bc83e419a82d551215b830b75cc278b5

af76fb91e313d8359f06269d5efa85b1f073a0a34d7749ce93a1b736a49b6f3f

Fees were calculated automatically by the app (BTC0.0001)

0 confirmations each, sent about 12:20 PM US ET this afternoon, so some 9 hours with no confirmations.  But, the amounts are tiny, so who really cares...  As long as I get the rest out even if it takes time.

For each transaction you paid 10,000 satoshis.  Broken down for each transaction, it becomes

txid 9d90d0170110364270ac161e59d9de03bc83e419a82d551215b830b75cc278b5 @ 258 bytes,
You paid a fee of ~ 38.8 satoshis per byte

 and for this one af76fb91e313d8359f06269d5efa85b1f073a0a34d7749ce93a1b736a49b6f3f @ 257 byes,
you paid a fee of ~38.9 satoshis per byte

 Looking at the info from https://bitcoinfees.21.co/

 

Seems that minimum transaction costs are increasing and 0.0001 BTC is no longer sufficient for a smooth transaction.  Double that amount would have put you into the ~instant tx speed though and it's still not that much; 18 cents?

 What software were you using by the way?

6510  Bitcoin / Bitcoin Discussion / Re: Very Small Transactions Unconfirmed for Days ?? on: January 10, 2017, 12:52:13 AM
Can we see a txid?  The fee you paid needs to be in line with the tx size.

Which is very confusing for average people. I know more than average person and still its confusing for me.
How can i calculate good fee for each transaction quickly from software wallet level?

 If you go to https://bitcoinfees.21.co/
You can see the recommended fee in satoshis per byte then I just use the slider in the Bitcoin core wallet.... most of the time Wink

Of course there is. Do you think that some things that are happen, are incidentally? Especially if you live in the USA. But am 100% sure that there is. I really don't know about Trump's plan, but there were moments that many tried to killed him. I think this is something and he has to be careful.

 There have been no assassination attempts on Donald Trump!

What does America? What animals in America are oppressed? I think you are just messing with us. America you did something bad? But understand, you are a Communist from Russia and I'm afraid of Americans. For Russian really America is a terrible country.

I'm american with russian troll opressing with me and it's a terrible country regards to messing an animal

 In America, you can buy diapers for your pet if they have a messing problem.

In America are very careful animals. In Russia, poisoned stray dogs, and they die in agony. In the USSR even on city streets went brigade flayers with hunting rifles and were shooting at stray dogs. Barbaric country!!!

 When the dogs begin to return fire, I will list Russia as a dangerous country!
6515  Other / Politics & Society / Re: Do you think there is a world government. on: January 09, 2017, 07:30:37 PM
I believe Trump's mission is to preside over America.
 A world government would only exist when elected representatives of every other sovereign nation wrongfully delegate the ability to enact binding legislation to a foreign body.  The European Union is an example of such a blunder but I don't think this has occurred on a worldwide basis yet.  There will be no danger of this type of agreement from Trump based on his views to date.

6517  Economy / Speculation / Re: What is the minimum profitable price? on: January 09, 2017, 07:09:42 PM
Where can I see what the minimum profitable price is for bitcoin miners.

I know it varies but a general ballpark. You'd have to calculate it but is there a site where it shows it?

http://bitcoincharts.com/  --> 2456335.762 Thash/s
and
https://www.hobbymining.com/bitmain-antminer-s9/ --> Very efficient at ~0.1 Joule per GH/s
and
https://en.wikipedia.org/wiki/Electricity_pricing --> a broad range of prices (so let's use $0.10 as an average)

2456335.762 THash/s is 2456335762 GHash/s
2456335762 X 0.1 J/GHash/s X 24hrs X $0.10 = $589520.58288 per day which produces 1800 BTC

dividing it out gives us $327.51 in electricity costs alone

now https://shop.bitmain.com/productDetail.htm?pid=0002016052907243375530DcJIoK0654 we can get some specs and pricing for miners.

Let's say an Antminer S9 is capable of 14 THash/s and assume the network is using only these highly efficient miners.  In this case, the network is comprised of 175452.55 S9s
each S9 retails for ~2100 USD and lets assume it will last for 1 year before becoming obsolete.  The network hardware costs for the year are 368450364.3 and per day would be 1009453.05 so per coin... $560.81 and lets add electricity to that = 888.32 per coin.

Wow.  $888.32 per coin!  I haven't included real estate, maintenance, cooling and internet connections/power supplies.  Obviously there would be some economies of scale for the manufacturer of the mining devices so they wouldn't be paying retail cost for the miners but that's a ballpark figure.

 $888.32

 It makes the current price of Bitcoin 836.12 seem like a bargain!



it's not make any sense this math is off

currently one antminer s9 is generating $281.3 per month at 1000khw, this mena that each month it consume only $36 while generating $281

now do $281-$36($245) and scale it to 1000 of them and you can see the whole picture, they have a net of $245 at current price each month

so if bitcoin was going down from now by $200 they would still profit, the minimum therefore is around $600, and because of this i can easily assume that the market will nto fall under $700

 Well I suggest you open your mind and look at it again.
With a 14 THash S9 it would presently take 90.24 days to make one bitcoin.  At 0.1 watts per GHash/s and 10 cents per kWh it will cost $3.36 per day to run the S9.  After 90.24 days you have paid 303.21 in electricity costs alone!  In my original calculation I used the entire network hashing rate - yet I see little difference in the per-coin electricity costs.

 Please point out where you get 36 dollars for a month of power to run the Antminer S9.  I'm curious.


The problem is that half of the network hardware is nearly or fully paid off by now. There is also no need to pay it off in the first month of mining. The production price is lower than 888, I promise.
At others here, Cost of production is not a floor price. Bitcoin price has, and will again go below production cost. It will happen eventually. maybe not any time soon, but price support is not set by miners.

  How did you come up with this little tidbit about half the network hardware being nearly or fully paid off?  What does it have to do with the cost to mine?  Half the current network speed was added in the last year and the hardware responsible for the previous half is nearly or fully obsolete.  New miners replace old miners at additional cost to the farms.  Also, I would like to know how I left you with the impression that there was a need to pay off the hardware in the first month of mining?  I said nothing remotely akin to that!

 It seems you know the cost of production or you wouldn't be able to state that Bitoin price has gone below the cost of production.  I don't doubt that it could possible dip below the production cost periodically and for very short durations but I don't know the cost of production for the farms - only for myself as a home miner.  Please tell us the true production cost of a Bitcoin.  

 Around 8 months ago, KNC miner declared bankruptcy with Scam Cole saying "Effectively our cost of coin – how much we produce the coins for – will be over the market price. The price is now [roughly] $480. With all of our overhead, after July, the cost will be over $480. All of the liabilities we’ll have after that time will be too high."  This announcement only 1 year after they started mass production of their new 16 nm Finfet 3d Solar chip.  They claimed it would have an efficiency of 0.07 W/GHash though I never saw any test results and it wasn't sold to the public.   Anyway, this was the only time I ever found anyone speaking of the cost of production so today I don't know what the cost is.  I do know that if miners can't mine and go bankrupt, the network suffers and transactions take longer to process.  I also know that more efficient tech doesn't happen overnight.
 No, the miner never gets to set the price of Bitcoin but the miner plays a significant role in the base price of Bitcoin, whether we like to believe it or not.  If miners go offline in significant numbers, that could be the death knell for Bitcoin.

Edit:  I believe GoGreenLight is the company that took over KNCs equipment and they now have just under 1% of the Bitcoin network hashing rate.

Same thing with gold.  A mine is viable so long as the fraction of gold in the ore allows for extraction at less cost than the spot price of gold.
Miners are going to mine while there is profit.


6520  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator/miner [v0.22] on: January 09, 2017, 01:51:46 PM
Anyone know what I need to modify to make the search start from a particular address and go up sequentially?

Basically I got a few GPUs that can no longer mine ETH and ZEC and for fun, I want to solve the 51th bit in the "32btc contest thread" located here
https://bitcointalk.org/index.php?topic=1306983.0;all

I just need the search to start at 1,125,899,906,842,620  and end at 2,251,799,813,685,250.




 Vanitygen isn't going to help you with that.  What you need to do is convert those to hexidecimal, generate the corresponding wallet import format private key and find the address.  Vanitygen randomly searches out addresses and compares them with your search parameters.

Code:
Take your decimal number.
I like this one: 1,125,899,906,842,623 because it converts to this

11111111111111111111111111111111111111111111111111 binary number

but you need to convert it to this

3FFFFFFFFFFFF hexadecimal number

then pad it with zeros to make it 64 characters

0000000000000000000000000000000000000000000000000003FFFFFFFFFFFF

now add 80 to the beginning (to make it a Bitcoin private key)


800000000000000000000000000000000000000000000000000003FFFFFFFFFFFF (keep this one in mind for later)

Code:
hash it once (SHA256)

08260BC6AE17D00E40464A8EE0DA4C9FDAF1BEFC14C528CFC169798D868860DD

hash that result  (SHA256)

53FA3A525E44DEF51F9A0B6E910E6DCA51AB0A99E1756BB97BE32E01308390A0

Now take the first 4 bytes (this is the checksum) and add it to the end of the red number

800000000000000000000000000000000000000000000000000003FFFFFFFFFFFF53FA3A52

convert that to Base58

5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nFAaVmEdoLi3nb9s
There you have the uncompressed wallet import format private key for your original decimal private key which gives you the public address of:

1JnSYv9ZQ4kLRANt4FgbGVYBPXCrpfek6P

Which is empty. (one down, many to go!)

 Seems like you need a specialized computer program to run through the possibilities for you but not Vanitygen.
