Re: WTB physical bitcoins

that is beautiful how much are you asking ??


It's in a weird place for price since it's rare so it's worth a lot, put since it's peeled and ungraded it's taking a bit of a hit in value.


Last few offers I had were between $250 and $300. So, somewhere in that range would be good at this point, its just sitting in storage.


If you want it, I'll cover the cost of shipping to minerjones, you cover the escrow and shipping to wherever you are.

Actually pulled some things to sell on the way to work this AM.

Have had it in my collection for over 10 years exactly as you see in the pictures, was peeled when I got it.

Would you be interested in a 1BTC that is not graded & peeled?

Would have to go to storage and dig for it. Had someone start a deal and then it fell though so it's just been sitting.

Re: 100 1964 Kennedy half dollars. 5 rolls of 20 coins. Not rated/graded

Each coin contains 0.3617 troy ounces of silver * 100 coins = 36.17 troy ounces
36.17 * $39.17 (as of this post) is $1417.00 + / - a few cents so yeah ~ $100 under melt.

If I was not sitting on a ton of silver already I would be in my car with cash on the way to his house instead of typing this.

Re: Error when paying BitPay invoice

...I have no idea why BitPay insits on using this payment protocol instead of the regular URIs, though!

Short version according to them is that it includes address & amount & fee
They have (or claim to have) had issues when fees were / are up people paying invoices with much lower fees then they should have so the TX sat in the mempool.

So this was created and they set the fees high enough to make sure payment should reasonably be in the next block.

Make of that what you will.

Not sure if this still works but:

Should pull the amount & address from the invoice.
Have not used it in a really really really long time but back in the day it did the job.

Yeah, what I was trying to communicate is that now the thread just vanishes.

Keeping it open with a warning about if you clicked the link would at least have the possibility of giving some people a warning that they may have been compromised.

Still, ban the OP and everything else, but at least there would be something there that people could see.

Over the years I and countless others have reported posts that linked to malware that were removed.
Should there be a change in policy that when this happens ALL the text of the OP is removed and all replies are removed but there is a big warning on the post that tells you that if you clicked that link you may have been infected.

Yes, it's the internet and we are not your mom, but outside of extra work for mods I don't see a downside.

Re: Solo mining single vs multiple miners question.

For the pennies a day or miniscule chance of hitting a solo block I would go for the NerdQAxe++

Yes if it dies / crashes you stop mining.
The other side is that you are only managing 1 device, not 4. So it's more time and effort and things to go wrong.

If they were all throwing off $10 a day it's a different outlook. For that little bit of $ do you want to manage more devices.

Re: WHALE JUST MOVED $1.2B DORMANT BTC - BLOCK 842,100 ACTIVATED

on 30/06/2025, 10:50:03 UTC
per blockchain explorer https://www.blockchain.com/explorer/addresses/btc/1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa that address has only 103.09357113BTC / $11,200,736 in it and has sent out 0BTC so that cannot be the correct address. That address is Satoshi's Genesis block.

Quote
The wallet "bc1q97g**************wwmep86jh" (Genesis block's first output) just moved 20,000 BTC.
That cannot be right because that is a BECH32 (Native Segwet) address and Bech 32 was not activated until August 24, 2017.

Thank you, and how is this value calculated?

For example, miningpoolstats adds up the hashrate of all the pools in their list and gets the total hashrate. And if the pool is not in the list, then its hashrate is not taken into account.
https://miningpoolstats.stream/bitcoin

As a miner, I was more interested in profit and uninterrupted operation of the equipment than calculation hashrate Smiley

But now I want to know a little more.

The client knows the difficulty and it knows how long it takes to find a block over the last 24 hours.

After that math:
Hashrate = ( (blocks solved in last 24 hrs / 144) * difficulty * 2^32 ) / 600

So you get that last rolling 24 hours of hashrate.
Not it's not perfect, but it's close enough.
There could be an unlucky few hours which would cause the hashrate to show lower or a lucky few hours that would show it to be higher.
In the end over the long run you can do the math yourself. You can change the 24 hours to 48 and the 144 to 288 and so on.

In github it's been weeks since Bisq Light Client Initiative Project received updates. We know eXch team isn't coming back so there isn't a donor who's going pay devs. Is Bisq Light Client Initiative Project dead ?

@OrangeFren is still active on the forum so they might be able to give an update in terms of funding and activity.
Also, and this is just me, if it's a side / hobby / low income project for people "real work" will come 1st.

I have a couple of projects that I started over the years and even provided some money for programmers to deal with that slowly died as they took on more lucrative gigs.

As for a bit of a drop over the past few days, it's been stupid hot all over the US.
And there are lot of miners in Texas. And the state of Texas likes to pay miners not to mine when it's hot out since they can't be bothered to fix their power grid.

Any reason you are hosting your site in Russia when you claim to be in Cyprus?
That is a clear violation of sanctions.

And since Cyprus is participating in MiCA USDT is not supposed to be on any exchange you have access to.

Also, no collateral no loan.

But, if you want anyone to even possibly believe you I would start by posting the Tron address and signing something with it to prove you actually have access to it.

Because I don't trust anyone, this makes you wonder if it's real or if

1) The government of Iran is doing it themselves to make the population hate Israel more.
2) Inside job at the bank (and exchange) with a convenient target to blame it on
3) Someone else who did not want the spotlight on them.

Probably none of the above just a bit of tinfoil hat paranoia.

Re: Need Help Bitcoin Core "private key for address is not known (code -4)"
by
DaveF
on 01/06/2025, 13:57:31 UTC
and get error saying Private Key for Address ****** is not known (code -4)
You probably created a descriptor wallet. I understand there are good reasons for Bitcoin Core to switch, but I find it annoying to deal with. Getting a private key is a lot of work.

I'm not even sure if the latest version still allows non-descriptor wallets, so I just used version 26.1. That link shows how I did it from the command line. In short:
Code:
~/bitcoin-26.1/bin/bitcoind -noconnect -deprecatedrpc=create_bdb -datadir=/dev/shm/bitcoin
sleep 5 #wait a few seconds
~/bitcoin-26.1/bin/bitcoin-cli -named -datadir=/dev/shm/bitcoin createwallet qr descriptors=false
~/bitcoin-26.1/bin/bitcoin-cli -datadir=/dev/shm/bitcoin getnewaddress

Running windows 8.1
Are you sure you want to be using outdated Windows software for this?

Same problem for me too and i know the password is correct. I get "null" in bitcoin core when I execute "walletpassphrase" command.
That's normal: it worked. Just continue what you wanted to do.

You did just reply to a post from 11 years ago. So.....

Hello,
Same problem for me too and i know the password is correct. I get "null" in bitcoin core when I execute "walletpassphrase" command.
Any suggestions?

What happens when you try to send?
Null is the proper response.

Have not really been following this, mostly because I really don't care about it, but Arkham has been wrong before with who owns what addresses.

In the end does it really matter? It seems to be their thing. Wait for people to make noise about some holdings and then come out with a press release saying "we found them" and then when it's shown not to be accurate never mention it again.

Tinfoil hat conspiracy theory:

When the cards were made he also generated a bunch of legacy addresses for some other reason with the same keys.
Was planning on a 2nd round of scamming by having those addresses also get funded from some other project.
This way when the PKs were "compromised" all could be swept.

Now, the question is why did they get funded now? The other scam is now progressing and he is starting to fund them to sweep later.
Sell 500 of something funded @ $10 each. But only fund the 1st 50 or so. Take everyone's money for the full 500 and then sweep the 1st 50.

But that's real paranoid bizzare thinking on my part. Other then that I got nothing.

It's not a class action lawsuit  it a purported class action lawsuit.

BIG DIFFERENCE.

It has not been formally certified by the court, meaning a class has not been officially recognized as a valid legal entity.

It can go forward or it can get quashed by a judge.

Should read, a lawsuit filed by someone who thinks they have a class action is trying to sue Strategy.

But, that does not make for a good clickbait headline.

Re: How to create Sheets of Keys with QR-codes

on 17/05/2025, 13:43:26 UTC
Good job Loyce

Side note, have to go dig it up but some coin maker years and yeas ago (Ravenbit? Silverwallet? don't remember) had some code that did something similar years ago. Didn't do the QR just the address on one side and the private on the other on a full sheet.

From a technical standpoint it's a tough decision. If you know the position of the missing characters you can recover a damaged private key.
Once a QR gets damaged beyond a certain point it's gone forever......
