[picture removed here]

The original version of our rig.  The woman in the picture is my mother-in-law.  [edit here] This was a very nice picture of a real person doing some chemistry in 1949.  The very first response calls her a bitch.  Kind of kills the mood, so I took it out.


Our latest version.  It has four cards and does 1.31 GHash/second.  It uses about 900 Watts.



My mother-in-law retired from the mining business years ago.  She still has those pearls.

Need help with missing bitcoins from Ledger wallet.
by
sgravina

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.  https://blockstream.info/address/bc1q9j4gmx73wxgeygwsnk93lamxejr44lr0fak0az
From there they were joined with many other bitcoins and spent into many various addresses.  This is a new bc1 address.  The blockchain.com 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.

Re: wallet.dat Recovery help! (100$++ bounty)

Check out this topic:

https://bitcointalk.org/index.php?topic=25091.0

It is a program that looks for bitcoin private keys on a computer disk.  I never needed it but tried it because it looked useful.  it worked back in 2013 with my wallet.  I deleted a wallet and put it to work on my disk.  It found all the keys and made a new wallet.dat file from them.

If you can't find the code I put my copy here:  http://gravina.x10host.com/thing/wallet-recover-0.3-linux.tar.gz

Give it a try.

If you do recover some old populated bitcoin addresses they may also contain Bitcoin Cash, Bitcoin Gold and Clams.

Hey dooglus,  Could you post these charts a few days ahead?   Today's chart would have been more useful last Saturday when I was wondering what price I should sell at.

... but what if you die, and your family don't find your key, or don't understand it, or think it's only a useless sheet of paper with some code on it, or simply throw it away... Does this mean the currency's gone forever?

This is what happened to Satoshi.

Right now the Bitcoin market cap is 44.7 Billion.  Mark Zuckerberg is worth 61.9 Billion.  So Bitcoin is worth 0.72 Zuckerbergs.  I predict Zuckerberg parity soon.

There is a strong correlation between trading Stellar and trading CLAMs on Poloniex.  Perhaps the single entity driving the price of both coins.

Here is the 1 week charts for both:

Re: What were your experiences with Bitcoin when you first started?

Early versions of the software contained Dragons.  Mining then was trying to get bitcoins from Dragons.  It was dangerous and several miners were lost.  After the switch from "Proof of life." to "Proof of work." bitcoin became much safer and more people started learning about bitcoins.

Those days are mostly forgotten.

I was first introduced to Bitcoin when my daughter came home from a trip to New York City with 57 bitcoins on her laptop.  They cost her $40.

Actually what, happened there?


It is impossible to know what happened.  Everyone involved is dead.  People who say they know what happened are old with unreliable memories.  They all have different contradictory stories.

Marry your girl friend.  Combine your living expenses and incomes.  Every week put her $1,923 salary in the bank.   Wait one year and don't have children.

Someone just sent 0.111899 BTC (~$50 today) to the block 9 address.  Those bitcoins will probably stay there for the next 10,000,000,000 years.

Re: 291.2409 BTC for a 0.0001 BTC transaction .

Omg this guy is an idiot. I wish I had that many bitcoin's, if I did I certainly wouldn't be so stupid with them. I hope the sender gets them back but I doubt it.

This guy is super smart, 2 words: money laundering, I am pretty sure the right guy got thoose fees.

If this is money laundering then how did it work.  Here is how to launder money.  You give me 300 bitcoins.  I tell the IRS that I made those bitcoins selling lemonade.  I give you back 280 bitcoins that I made selling lemonade and tell the government that you sold me lemons.  The key to money laundering is a believable lemonade business and lies.

Where are the believable income stream in this big fee laundry?  The bitcoins don't look the least bit washed.
