1  Bitcoin / Hardware wallets / Need help with missing bitcoins from Ledger wallet. on: June 23, 2019, 06:02:13 PM
0.9 bitcoins have been moved from my Ledger wallet.
    Transaction ID: 63d60b9089d0bb9074c43e85e0ddd05137eee96c52ce060caa931a4e6e4fe938
    Ledger wallet Public Key: xpub6DNcmsc3CStHQcnfTiTgF2SkM91UfmT9SSYz49t64Zc6rnHqtuQnmxmXxDyHkL7tpqUfSsdoZ6c cWPoXHAiYeAwHGSk4NdbDivup2PGEX11

These bitcoins were on a Ledger nano.  They were there from 12/2017 till 06/12/2019.

I did not do the last transaction.

Nobody has access to the Ledger device.  It has not been moved since the last time I used it.  Nobody has access to the secret words that set up the device.  They are on a piece of paper in a location separate from the device.  That paper has not been moved.  There are other secret words on that paper for other wallets and those wallets were not drained.

The receiving address is: bc1q9j4gmx73wxgeygwsnk93lamxejr44lr0fak0az.
From there they were joined with many other bitcoins and spent into many various addresses.  This is a new bc1 address.  The explorer does not recognize it.

The last transaction I did was: 890eb8e61d383e98b2e1acf4ce22ffd889c08ce23cf171e59946457217fcb000.  This was a move of 0.12167207 bitcoins from a Coinbase account to my Ledger wallet.

Does anyone have an idea of what happened?

Until I can figure out what happened I am not going to trust Ledger wallets.

3  Economy / Computer hardware / [WTS] KNC Juipiter. October batch. 570 GHash/sec, 609 Watts. eBay auction. on: June 23, 2014, 03:31:12 AM
I am selling my KNC Juipiter.  This is the October batch.

570 GHash/sec, 609 Watts.  Works great, never a problem.  Never overclocked, it was making too much money for me to risk breaking it.

No power supply.  (I can sell a power supply separately.)

This is now an eBay auction.  Starting bid = $210.00, about half of what it is worth.

Here is it hashing away at Eligius.

Avalon 1 3 module ASIC bitcoin miner, 82 GHash/sec, 700 Watts.

Check out my Ebay auction.

This is one of the first batch of 300 Avalons.  It made 3.5 bitcoins a day when I got it April 2013.  The people who got theirs on time were making 15 bitcoins a day.

It only makes 0.0035 bitcoins a day now.  1000 times less.  At the current difficulty of 11,756,551,917 it is profitable if your electricity cost less than $0.14 per kWattHour.

6  Bitcoin / Bitcoin Discussion / How to talk about bitcoins. on: January 25, 2014, 11:29:14 PM
At 0.39 into this video is a fantastic explanation about bitcoins.

So save you the time here is the quote,

If you buy a Bitcoin, which is worth, like, 214 dollars... American... without tax... that Bitcoin is sent to all these little guys... in their little tiny world... in the Internet... and they hold on to them, and then they use YOUR Bitcoins to buy whatever YOU want... for you.
7  Economy / Computer hardware / [WTS] Some water cooling stuff. on: January 25, 2014, 01:44:48 PM
Check out my eBay auctions:

Radon 5870 Water Cooling Block.
Radon 5990 Water Cooling Block.
Intel CPU Water cooling block. Heat Killer 3.0.
Two water cooling radiators and various couplings.

Auction ends Sunday January 26, 2014.  And as of now (January 25, 2014) the bid prices are really good.

The price may be low because I mispelled Radeon and it is a 5970 water block, there is no 5990.

I will take Paypal, bitcoins, litecoins, or NXT.  No Doge or Coinye!

Escrow OK though for such low prices I don't think it is necessary.

This is a Self-moderated topic because I've never done that before and I want to see if I can delete the topic after it is no longer useful.  I don't want the Sasha Obama or Jenna Bush finding out that I sold a radiator 30 years from now.
8  Economy / Speculation / Peer to peer digital Ponzi. on: April 03, 2013, 11:16:59 AM
Two months ago all my digital coins together were worth less than the amount of money I just made while eating a bagel.

I am now of the opinion that bitcoins are a Ponzi.  As in most of the gains are coming from new investors and not from any economic activity.

It is hard for me to conceive of enough drugs, gambling and Alpaca socks to justify all this value.  Then again if I really think about it is hard for me to believe that there are seven billion people in the world.

The network has become sentient and figured out how to get people to give it government backed money.

Like all Ponzi's I wonder: What is the network going to do with all that money?

9  Bitcoin / Hardware / Somebody is trying to steal batch 1 Avalon shippments from DHL! on: April 01, 2013, 12:37:58 PM
I just talked with DHL.  Somebody called them and changed the address of my shipment to:

1826 W Pearce Blvd STE 104
Wentzvill, MO 63385

Because I caught this in time the package will be delivered to me.

The reason I figured this out is that when I looked at the tracking web site the last two entries were:

11 Recipient moved BOSTON, MA - USA  07:52  
10 Arrived at Delivery Facility in BOSTON - USA BOSTON, MA - USA  05:54  
10  Bitcoin / Hardware / Avalon should start mining for the missing batch 1 customers. on: March 27, 2013, 09:59:43 AM
I am losing 4.5 bitcoins a day because my batch 1 computer has not arrived.  Avalon has no response as to why.  They have not even acknowledge shipping my computer.

Time is precious.  These computer won't be profitable for long.

According to Yifu Guo's recent interview Avalon has several computers in testing:

One of these is mine.  Avalon, please take one of your testing computers and point it to my account at my minning pool.  As soon as my unit arrives you can stop sending me shares.

Avalon should do this for all the customers who have not received their batch 1 computers.  Especially since they have publicly stated that all the batch 1 units have shipped.

I have sent the same request via email to: Yifu Guo <>, support ticket at:, and a personal message to:;u=68196.  None of these channels have worked in the past so I am making this request public.
11  Alternate cryptocurrencies / Altcoin Discussion / Does GPU litecoin mining burn graphics cards? on: March 10, 2013, 06:35:34 PM
I noticed this morning that mining litecoins could be more profitiable than mining bitcoins.  So I finally tried to GPU mine litecoins on my PC using cgminer.

I have 2 5870s in a windows 7 machine.  I turned on the mining at intensity = 10 and got 170 kHashes/second.  Then I tried intensity = 16 and got 800 kHashes/second.  But at intensity = 16 I could smell warm carbon, the smell you get when you burn a resistor.  The GPU temperatures only got to 75 degrees.

So I turned that off!

Does litecoin mining burn graphics cards?  Are my settings too aggressive?

I'm back to bitcoin mining and the cards still work.  These two cards have been bitcoin mining at engine clock = 940 MHz, memory clock = 300 MHz for over a year.

Here is the command I used:
cgminer-2.11.0-win32\cgminer ^
--scrypt ^
-o localhost:9332 -u username -p password ^
--auto-fan ^
--shaders 1600 ^
--worksize 256 ^
--intensity 16 ^
-g 1 ^
--gpu-memclock 1300 ^
--gpu-engine 940 ^
12  Bitcoin / Development & Technical Discussion / Is there any problem with running 2 clients with identical wallets? on: March 10, 2013, 02:59:42 AM
If I turn on two clients each with the same wallet file will I have any problems?  I don't need to do this.  I just thought of it because I move a wallet from one computer to another.

14  Economy / Currency exchange / Dwolla may only be used in connection with United States Financial Institutions on: October 25, 2012, 04:02:10 PM
The title is a direct quote from the Dwolla terms of service.

Quote from: Dwolla Terms of Service
Dwolla may only be used in connection with United States Financial Institutions: User funds must originate at a United States Financial Institution, and Dwolla will only instruct Veridian to transfer funds to a United States Financial Institution associated with the appropriate Dwolla User.

This paragraph prevents using Dwolla for MtGox (not a US institution) Withdrawals.  Why then does depositing money from MtGox into Dwolla still work?
15  Economy / Marketplace / This is where bitcoins go to die. on: October 06, 2012, 10:38:07 AM
Bitcoin Savings and Trust
Global Bitcoin Stock Exchange

Somebody should start a business called "Bitcoin Graveyard".

How do the bitcoins know where to go when they die?

Is there a mystical part of the protocol that tells bitcoins when they should leave this realm?
16  Bitcoin / Bitcoin Discussion / Someone just moved all the bitcoins! on: September 07, 2012, 06:28:05 PM
Here is a transaction with 21,000,000 bitcoins in it.  How does that work?

I saved a screen shot of the block explorer.  It changed from this appearance within a few minutes.  I'm sure the fee would make some lucky mining pool happy.

17  Bitcoin / Bitcoin Technical Support / How do I spend a small amount of bitcoins? on: August 08, 2012, 12:48:58 AM
I have 0.00001 bitcoins in my wallet.  This wallet has 10,000 transactions in it from playing satoshiDice.  (playing has not been good for me, I'm down 30 bitcoins).  I would like to delete the wallet and start with a new one.

When I try to spend the 0.00001 bitcoins the client asks for 0.031 fee, so I can't spend them.  I tried putting 10 bitcoins in the wallet and spending the whole amount but it still asks for the 0.031 fee.  If I subtract 0.031 from the total, spending 9.96901 then the fee reduces to 0.0005 bitcoins and I am left with 0.0305 bitcoins that I still can't spend without a 0.031 fee.  Thus I can't spend all the bitcoins.

0.00001 isn't worth worrying about but it just feels wrong to destroy them.  I'd rather give them to a miner.

Are these bitcoins unspendable?  How do I spend and/or give them away?

Is there a way for me to set the fee larger so that I can spend them.  I'm running the linux 0.6.3 bitcoin-qt client which doesn't have a preferences menu like my Mac client does.

It's not me.  I do about 12 GHashs/sec.
19  Other / CPU/GPU Bitcoin mining hardware / Slow 5870 card. Advice sought. on: March 25, 2012, 02:34:35 AM
I have a Diamond 5870 which stopped working.  It would not display video at all.  I tried to get Diamond to fix it but they only say it's out of warranty.  They won't answer the question of how much it costs to fix it.

So I put it in the oven at 350 F for 10 minutes and let it cool.  This on the idea that there was some broken solder on the card and the heat would rebind it.  The card still didn't work.  So I left it alone for a month.  Then today I tried it again just to make sure it was broken and it works!  But it is slow.  I have run it at 620 MHz gpu / 300 MHz memory for 10 hours now.  At 630 / 300 it only last 10 minutes.  At 850 / 300 it last 5 minutes.  At 900 /300 (where I usually run a 5870) it dies instantly.

Any idea of what the problem is?  Why did it not work and then work again?  Can I make it work better?  Should I use it as is (it does about 280 MH/s) or should I try to sell it as a deficient card?

20  Bitcoin / Bitcoin Discussion / My mistake lost me 74 bitcoins. [Coins found.] on: March 08, 2012, 05:09:15 AM
I just made a 74 bitcoin mistake.

I just sent 73.81264095 BTC to 1w2giXiGAHiFnjyUyVyMubszKRQb8MEYt

I got that address from the list of addresses that I have sent bitcoins to in the past.  I meant to use an address that I receive bitcoins to.

I intended to transfer those bitcoins from my MtGox account to my wallet.

Does anyone know how I might find the owner of that address and kindly ask for the bitcoins back.  It is an address that my daughter used on June 7.  She sent 1 bitcoin to them.  It is either a friend or more likely a gambling service.  For a few days there she was playing one of those stupid games where you guess something and either win or loose.  Is there a list of gambling sites that were active back in June?


--edit, next day--

The coins have been recovered.

It turned out the address belonged to both a friend and a gambling service.  It is the site  The site is partly owned by my daughters friend.  He is sending my coins back to me as I write.

Let this be a leson to everyone out there as clumsy as me.
