Let us know how it goes.
Keep in mind the sync will slow down as you progress, since all the blocks are full and it's a lot more data to crunch, but once it's done it's fine.
I did not do a lot of testing on performance of CPU / RAM will effect it and such since it's an old machine just dedicated to that.

What are the prices over there for m.2 drives?
I tried to find this one: https://www.amazon.com/gp/product/B07PHJCCY3
or this one: https://www.amazon.com/gp/product/B07ZGJVTZK
on other Amazon sites but it keeps redirecting me back to the US site.

Both are $34.97 + tax here.

Another round of "Bullshit Bingo", I miss the word quantum in it, to make it complete.

More of buzzword bingo.
But, they are going to get a bunch of gullible people to throw money at them for their new process.

Couple of options
1) Apollo BTC: https://shop.futurebit.io/collections/all
2) Find a used S9 and mod it a bit: https://bitcointalk.org/index.php?topic=5160194.0
3) Something like a heatbit: https://heatbit.com/      or    https://www.ebay.com/itm/266071039921

Keep in mind there is a 99.9999% chance you are going to loose money.
The cost to buy it, the cost to run it, are all going to be there.
If years later you never find a block. It's money that is spent and never coming back.
But....as you are looking to lottery mine, I am thinking you know that already, just wanted it out there in case someone else sees this.

864  Bitcoin / Development & Technical Discussion / Re: Electrum server on Windows: Fulcrum on: August 19, 2023, 11:34:59 AM
The biggest thing I like about it, is that since it is a full electrum server it allows you to just point your client at it and go.
Want to import a private key into your wallet, nothing else to do.
You can have your desktop and your phone and just about anything else you want pointing at it.
Since I have it mapped back from the public IP space to it's private IP I can use it anywhere.

I am not super concerned about privacy, as I have explained elsewhere, but it's still nice to know that it does make it more difficult to track what I am doing. On, the off chance anyone wanted to.

As for the storage, to run core you are already over a 512GB drive. So you need the 1TB anyway. The cost really is so minimal as not to matter.
Amazon has name brand 1TB m.2 for under $40 delivered.

865  Bitcoin / Project Development / Re: [bip39.org] Open Source BIP39 Mnemonic Generator via Email and Password on: August 19, 2023, 11:19:46 AM
I do think that this project is an answer in search of a question, since just about every wallet is going to do their own key generation anyway.
If people are more interested in security they will use a hardware wallet.
If they are don't care they will use whatever is provided buy the wallet they are using.

However, you really should force a minimum entropy that is somewhat large.

866  Economy / Exchanges / Re: Bittrex to shut its U.S operations on: August 18, 2023, 12:02:35 PM
Okay so regarding the SEC charges we talked about a couple of months back, it looks like Bittrex has agreed to settle and pay a 24M fine:

Crypto exchange Bittrex settled charges of offering U.S. investors access to unregistered securities on Thursday, agreeing to pay a $24 million fine within two months of filing a liquidation plan for the exchange.

Your thoughts on this? It would be interesting to see what the rest (Binance, and Coinbase) is going to do as well.

The question is did they agree to pay because they are leaving? Just add it to the cost of shutting down operations and move on.

Coinbase, being a public company would have to do it differently. If they can justify that paying a fine and moving on is a better financial operation then fighting it then they might do that. But, if some shareholders think and can reasonably see fighting the case being a better option then you have to look at that too.
 
Binance, who knows, they will probably just pay whatever fine that comes up. They charge so much, adding a few more fees to come up with a few million dollars off the backs of their clients would not be that hard.

868  Bitcoin / Development & Technical Discussion / Re: Electrum server on Windows: Fulcrum on: August 17, 2023, 04:37:04 PM
So with ordering the m.2, waiting a day (thanks Amazon), installing it, installing windows and updating, and installing core and downloading the blockchain and then installing Fulcrum and letting it do it's thing it's back up and running.

Probably, not worth really having my own Electrum server up and running, but it's nice to know it's there.

Eliminating the entire windows good / windows bad things. The setup it brain dead simple. And now that I have it configured to never reboot (hopefully) unless I do it, the rebuild should not be an issue.
And if something does happen, using even what is the cheapest 1TB ssd I could find, really does make the entire process of blank machine to finished and running very quick.

869  Bitcoin / Bitcoin Technical Support / Re: How do I "restart with -reindex-chainstate."? on: August 17, 2023, 12:17:08 PM
Keep in mind what I posted over a year ago: https://bitcointalk.org/index.php?topic=5399730

Yes you can get it running on a 2013MBP but it's never going to be good. Just due to the way Apple did things the hardware in that unit was not the fastest out there. It will be a good learning experience for you, but it's never going to be a good way to run core.

And running something like the reindex is going to take a long time due to hardware limitations.

870  Bitcoin / Mining / Re: Compass Mining on: August 17, 2023, 11:42:17 AM
A bit late to reply to this, but depending on the number of miners and the power you need if you can't host them yourself you are probably better off finding a local data center and reaching out to them to see if they have anyone who has spare cabinet space who is willing to sublet to you.

More and more DCs seem to be looking for the 4 or 5 cabinet and up people who then sublet them out.

It's kind of a win - win they deal with fewer but larger users, and people who only need a little rackspace in a DC can get it without having to overpay.

871  Bitcoin / Bitcoin Discussion / Re: PayPal UK To (Temporally) Halt Bitcoin and Crypto Purchases on: August 16, 2023, 04:52:14 PM
It's not like they are the only way to get BTC / crypto in the UK
Plenty of other options. But, they are so large that they probably do have a lot more casual crypto users then we think they do, just because of their size.

Oh, I want to get BTC
I already have a PP account.
Yes my crypto friends tell me to go elsewhere and that the PP rates are not great. But I have an account and it's quick and simple.

That kind of thing. We all have inertia over things like this even if we don't want to admit it. And it costs us. But we do it anyway.
From using a credit card that may not have the best rewards to not moving money to and account with better interest rates to buying crypto at PP.
It just falls to the convenience factor.

Now, lets see if the halt is real or just something that has spread.

Nah, Intel has been screwing up for decades. https://en.wikipedia.org/wiki/Pentium_FDIV_bug
Different world back then, but still the same problems. Big glaring issues with people trying to figure out how it made it past testing.


CoinDesk also takes up the topic again in an article: Disappearance of $900K Puts Focus on Vintage Bitcoin Project Libbitcoin

Quote
Information security firm Distrust says a total of at least $900,000 was stolen across multiple blockchains.

...

Milk Sad is not restricted to Bitcoin. Ethereum, Zcash, Solana and even Dogecoin are among the list of eight blockchains affected.

Similar but not identical vulnerabilities have been detected in Cake Wallet and Trust Wallet, both multi-chain wallet apps.

Typically, seed phrases are created using a generator capable of producing a set or “key space” with a dizzying number of unique word combinations represented by the exponent of a binary digit or “bit” – essentially, the number two raised to the power of 128, 192 or 256.

...

Source: Disappearance of $900K Puts Focus on Vintage Bitcoin Project Libbitcoin

According to the security firm Distrust, at least ~$900k was stolen on multiple chains.

Similar problems were also found with the two well-known multi-coin wallets Cake Wallet and Binance's Trust Wallet. Especially Trust Wallet in particular is likely to be used by many forum members due to its aggressive marketing by Binance. Another reason to withdraw your coins from any Binance product.

I do (did) have funds in cake. Finally moved them out last night. It was a non trivial amount but not enough to loose sleep over if they vanished.
But I do know several other people using it and they had no issues either. Wonder how vulnerable it really was.

I only had 2 alts in there and only only because it was the easiest one to deal with when someone wanted to pay me with an alt and it was the 1st one that looked decent. And then when someone else wanted to pay with an alt it wound up in there too.

Makes you wonder if cake is legit vulnerable how many people have some funds sitting in it for years like I did, and were planning to move them out soon. And just never did.

873  Bitcoin / Bitcoin Discussion / Re: Is Alby a legitimate extension for lightning network usage? on: August 15, 2023, 01:11:59 PM
~snip~
is there a particular danger to run alby browser extension on a computer linked by ssh to a raspberry pi running bitcoin core ?

This sounds like you have a hot wallet, I wouldn't recommend having more than a small amount of BTC on any computer connected to the internet.

If you only have a small amount then it would be fine to run alby (which I think it's a reputable extension anyway).

If you have more than a small amount, then transfer that to cold storage.

To put it even more simply there is always a danger of having ANY funds that are accessible by ANY device that is online.
Phone / desktop / whatever.
Yes, your installation of core might be safe. But is the PC that has this extension installed gets infected and someone gains access to that machine. Then they can do whatever they want on your network.

It should be fine, but unless you are really tight on drive space it's better to run a full node.
There are just some things you will not be able to to do with a pruned node.

IF all you are doing is sending and receiving from addresses that are new it does not matter.

876  Economy / Exchanges / Re: unconfirmed bitcoin transaction on: August 14, 2023, 11:17:10 AM
The OP isn't new to bitcoin because his personal website's for Jambler. He won't post TXID's because he didn't buy bitcoin from bitcoin.com so he can't. I've seen a similar post about unconfirmed transaction.

He's asked Sending Money From a Debit Card to a Bitcoin Address. The OP's saying he's new to Bitcoin. I don't believe.

Could you post the transaction ID? That might help. Were the funds sent to your non-custodial wallet after you bought from them? I can't imagine an exchange paying such low fees. Did you have an option that allows you to select the fees by any chance?

I agree, I don't think they bought BTC at all. Just positing some things that have no point.
Registered yesterday and started spamming but putting it in the form of questions.
Check out the other junk / spam they have posted.

Putting the OP on ignore for now.

877  Economy / Service Discussion / Re: Someone help me solve this cryptowaves.app mystery on: August 13, 2023, 05:27:31 PM
It works if you include "www". It doesn't if you don't.

We are all accustomed these days to including/excluding "www" at will, since every major site will redirect you to the correct landing page, but www is actually a subdomain. Type in www.bitcointalk.org and you will redirected to https://bitcointalk.org. Type in reddit.com, and you will be redirected to www.reddit.com. The owner of this site simply hasn't configured their top level domain to redirect to the www subdomain.

It's a DNS issue

If you look up cryptowaves.app you get : 162.255.119.113 which goes to namecheap where the domain is registered.

If you look up: www.cryptowaves.app you get all the information for heroku which is where it runs.

    alias = powerful-pumpkin-jp0rxzcpyumcnz5az60yqpuq.herokudns.com.
powerful-pumpkin-jp0rxzcpyumcnz5az60yqpuq.herokudns.com.

    54.91.59.199

As a side comment heroku is owned and run by salesforce which has had some security issues (who hasn't) but also some privacy issues.

Just because the developer says it's secure you still don't know what is going on with the back end.

Yeah, a lot imploded but I know a few people sitting on millions of dollars since their 15000 shares have now split twice and are trading at $75
But, it was worthless back then.

Yes, not a perfect analogy since there were a lot of places that did implode. But some people made out really well.

879  Bitcoin / Bitcoin Technical Support / Re: REWARD 1 BTC! Electrum wallet help me! on: August 12, 2023, 06:08:54 PM
i did that, BUT it's wrong because my output paths don't match, neither does the private key to the address. I have to create a wallet with a withdrawal path suitable for a private wallet, because initially electrum creates it differently, I need m/0/58

Look dude, I don't want to call you a liar, but there're some significant contradictions in your story.  Either you totally flubbed your wallet file and your seed phrase (one or the other okay, but both?) or you forgot some extension word (unlikely since you're seeing transactions in the wallet without an extension) or, the most likely answer; you purchased/found/downloaded this file that was purposefully corrupted to make it look like it has some bitcoin in it.

If you have a private key that restores an address other than one you want restored, then you don't have the right private key.  It's that simple.  Going around in circles asking the same question worded differently won't change that fact.  You're not the first person here insisting he's had an obviously butchered file since it's creation.  

Yup.
But think of how much of everyone's time the OP has now managed to take up.
Because wait for it, none of you bothered to google the address.
For 1FpqQnKQCgDkJFMC94JL8FpRyHTZ3uRVZ1 a quick google gets you
https://www.coursehero.com/file/110545615/Bitcoin-Etherium-private-keys-with-balance-2020txt/
If you toggle reader mode in firefox you can see that address.

880  Economy / Reputation / Re: PrimeNumber7 is an alt of Quickseller, Take 2 on: August 12, 2023, 05:33:42 PM
I have not dug into this enough to really comment on it, but and this is just me, certain misspellings may be from copy - paste - accept in browser spell check when you see the underlines.


I have always been under the impression that Quickseller was a somewhat intelligent person and cannot see them doing copy/paste. I'm not sure if they have spellcheck enabled or not, but seif they keep seems like that would be a no if they keep misspelling certain words.

I'm not saying a copy / paste and entire post. Just some text from A to B. Then when spellcheck gives it a red underline they instead of correcting it they accidentally add it to the dictionary and then it just persists. I have done it, as have countless others.

If there are OTHER indicators that 2 accounts may be linked then it's another data point. But, by itself or only with very nebulous connections I would not use it to link accounts.

Either way, I wish I had more time to dig into it, but I don't so I'll just back out of this conversation.
