And a year after they started taking pre-orders
https://twitter.com/nvk/status/1755617609905566090

So still no ship date but at least it looks like they are producing something.

Still too little to late with no updates.

Also, makes you wonder if you did order one, and they are claiming they don't retain customer data for that long, how & where did they keep all the info from the orders?

With the 4 yes, with the 5 no.
It *should* work exactly the same, just faster, since they are just running their stuff on top of the Pi OS.

BUT, if they made any assumptions in the installer about it being a 4 you may (doubtful but may) run into some issues.
Had that years ago when trying to install some stuff on a RPi4 that was old and had no idea what it was and just did not install. A 1 line patch by the developers fixed it.

The 5% fee is back to 0.5 or 1% again. Probably because Binance delisting Monero. Monero dropped 17% now. Imagine that, people dumping their privacy coin because they can no longer trade it on a KYC exchange....
That's an action of some real cypherpunks right there.

Probably also a lot of people that keep their coins on exchanges for trading that have no way of moving it to their own wallet since they don't have one....
The just sell it and get out attitude.

More for us at better prices....

284  Bitcoin / Bitcoin Discussion / Re: US gov’s planned $118M Bitcoin sale is ‘peanuts’ compared to GBTC on: February 06, 2024, 03:38:07 PM
Well.  Bad timing I guess.  I wish there was a RemindMe bot so I could check out how much the Government has missed on by deciding to sell Bitcoin before yet another presumed historical Bull Run.

Or is there any time limit now that they pushed the notification of the sell?

It's the government, they don't operate like that.
When they have property to dispose of, no matter what it is, it is sold / auctioned on a known schedule. They don't pick and choose the best time to do it.

It's just the way it is, and it's probably for the best. If they wanted to sell at the next BTC bull run or sell property at the next real estate ATH and it didn't happen but instead the prices went down for whatever reason it's going to be worse.

You might want to close/lock this and open another thread that's self moderated.

How are you watching this? Are you in the courtroom or is there a place that anyone can watch it online?

How many others are in the courtroom and how big is it? Just more for a reading of how many people care. A packed courtroom gives a different feel then one with just lawyers and a few other people in it.

286  Bitcoin / Mining speculation / Re: 2024 Diff thread happy New Years. on: February 05, 2024, 04:30:45 PM
121% is truly a magnificent number. It will kill my mining if we do 20% jumps.  But I can see us going way past 800eh by apr 1 2024.

which I do not think is possible.  But what do I know. Not much

121% in a single epoch is against physics and economics, noway on earth it's going to keep the pace, we will end up with a small increase of 2-3% IMO.

There are probably a bunch of people giving older gear that was off one last run before they sell it after the 1/2ing.
Yes you could probably buy the BTC at a better rate, but if it's there and idle might as well turn it on and get some BTC.

Goes against logic, but I have seen it with my own eyes. There is NO possible way a T17 can make any BTC with $0.06 power but there are a bunch that were on since mid January in the colo that have been off for months.

287  Bitcoin / Development & Technical Discussion / Re: Why do 95% of node runners refuse to undate their software? on: February 05, 2024, 03:53:32 PM
The bitcoin node as I have been made aware adds to the decentralization of the network. looking through this article on the backslide of bitcoin node operators in updating their software. This thought sneaked in, why people who  run a software that authorize the order or mode of the bitcoin network are inattentive to upgrading their nodes. In his analysis he stated that it takes 3 years for 95% of bitcoin node operators to update their software. I don't run a node, yet, exploring and checking up on what's like to run a node engrosses me. What could be the distraction? Do they forget?

Zombie nodes a lot of times. People spun them up for project 'X' and then when that project didn't work, or get funding, or whatever, they just left them running.

Although, there are a lot of people here trying to run a node on a RPi or an old PC or a $10 VM, a lot of times it's businesses with 'real' hardware in the background and 1TB of storage and 8GB of ram and a bunch of virtual CPU cores is nothing. So when you contacted me to get that project running and I setup core 20.0 over 3+ years ago in your data center it was the current version. When the project went nowhere it's still there running because nobody wants to bother taking it down since they may need it sooner or later and it costs them nothing to leave it there.

Side note that is how a lot of data breaches happen in general. Just old things sitting there that nobody maintains since it's not their job.

-Dave
288  Bitcoin / Development & Technical Discussion / Re: Starting a Bitcoin Node using a VPS on: February 05, 2024, 03:12:54 PM
Since the cost does not include enough space for a full node how much does it cost to go to 1TB for storage?
It's not much work to do a quick pre-install of BTC and then bill you at a profit for bandwidth overages and storage overages.

Remember, most if not all hosts give you X bandwidth and even if you are doing your initial sync from a local node to your local node and never touching the internet that bandwidth still counts against your monthly total.

While your statement generally is true, it seems Contabo also offer storage-focused option. But with very low price, i would question the reliability and actual performance of such VPS.



It's also worth to mention there are at least 281 reachable full node which use Contabo, according to https://bitnodes.io/nodes/asns/?q=51167. Using less popular datacenter would be somewhat better.
It's quite difficult to find ASNs less populated than that. IPs under the same ASNs doesn't mean that they are under the same datacenters; they can also be among a bunch of different datacenters that are geographically located in different locations.

You're right. But IIRC we can't find better or more accurate data without much more effort.

2 cores of what CPU? 3GB ram is a bit light but doable.
For under $70 a year it's not bad. If there is some sort of price guaranty. Do you want to be moving in 6 months because it's now $9.99 / month?
Have dealt with that a few times over the years.

Also, does that come with a dedicated public IP or are you behind a NAT?
If you are only going to be on TOR for the node it's not a big deal, if you want public access it's a different story.

Yeah, I can go dig around the site but I'm on mobile at the moment.

BUT not tell people what address it's signed with.

So, until there is a NEED to prove you wrote something there is no way to know if it's valid or not.

So in theory 10 years from now I could prove that on 4-Feb-2024 because of the above text and signature I controlled the address bc1qugdlj4sghspzyx5w74xm77mn67auyzc2y6huls

I cannot see another need other than that.

-Dave


Yes that is what I was trying to explain I was trying to do. If the document is public, this allows people to view it, but I can selectively prove the ownership to parties I want to do that with. Sounds like a 2nd hashing is a good way to do this.

The issue is that once you let the proof out, no matter who you reveal it to, it's out there because they can then tell anyone.
The other side is you show them in a way that they can see but not duplicate, BUT and this is a big important BUT, they have to then trust that you are not doing something shady in the background.

If you want to give them the process / address / info to prove it then you are giving them the ability to prove it to the world.

Don't know if that matters for what you are trying to do, but it's something to think about.

Any hardware wallet that works with PSBT / BIP-174 will work.
But, is it really worth it to just though all the hoops to get it to work.

There are other easier ways to do it. Better ways? Tough call. Easier ways? Yes.

292  Economy / Reputation / Re: What happens if someone sells an account on a neighboring forum? on: February 04, 2024, 02:41:10 PM
IMO it's a who cares. What you, or someone pretending to be you, at ANY other forum does not matter.

Here regulates here and there regulates there. Lets assume I setup an account someplace else and I teleport my account there.
And never use it. And then for whatever reason it gets compromised. That account then does bad things.
But...I never used it and I don't care. Why should that matter to me here. If I then go in and remove the proof here that it was me there what does it matter?

Because:

1) The account was compromised and is was not me so who cares.
2) It was not compromised and it WAS me, but you can't prove it.

Either way, it's a there problem not a here problem.

If you have the bandwidth at home or wherever, I have been doing these for people:
https://www.amazon.com/dp/B0C7GKG3PZ/ref=syn_sd_onsite_desktop_0?ie=UTF8&pd_rd_plhdr=t&aref=akpWrBFv5f&th=1
take out the 512GB drive that comes with it and put in a 1TB. For under $250 you have a NEW machine that does not pull too much power that can more then then run a node + electrum server and a LN server if you want.

The main question is what is going to be different then all the other open source block explorers out there that you can just run quite easily yourself?
https://github.com/janoside/btc-rpc-explorer
Has a good API and does a lot in a VERY small footprint.
Not the fastest but for doing it yourself for your own private use or small business it's fine.

296  Bitcoin / Development & Technical Discussion / Re: If Someone Sends Funds to a Previously-Used Address, Will I Still Receive it? on: February 01, 2024, 02:59:57 PM
Just to tag on, there are some ONLINE CUSTODIAL services THAT YOU SHOULD NOT BE USING that only allow 1 transaction per address.
If you (or anyone) send anything else to that address then they keep it. Full stop.

Just a heads up on that. Not your keys, not your coins.

Never ever give out addresses that you do not have the private keys to. Paying 100 extra TX fess because all coins come into your control before you send them elsewhere is better then loosing that 1 TX because oops, that address is no longer valid.

Same with you sending out of exchanges to someplace else. Exchange -> you -> wherever. Or you can wind up having this happen to you: https://bitcointalk.org/index.php?topic=5476264.0

Something like this?
https://www.mailboxde.com/
or this
https://www.businesspalma.com/en/mail-drop-spain/

There are a bunch of them but are all separate so it's not like you can get 1 and get an address in 5 countries.

Probably better anyway in terms of privacy to have a different company in each country.

298  Bitcoin / Wallet software / Re: Scammer lead developer resigns from honeypot Wasabi Wallet on: January 28, 2024, 02:16:39 PM
They self sybil and fill Wasabi with fake volume. Very easy for them to link inputs and outputs.

Just to keep fair criticism here, sybil attacks in coinjoins are easily detectable, in order for the attack to work efficiently in deanonymizing a certain input -- the coordinator needs to refuse connection confirmations from all other participants, so if your input has not been spent before and the coordinator rejects your connection it's safe to assume that it's preparing for a Sybil attack on an input it identified earlier in the current round.

Obviously, at this stage, it's hard to tell if enough adequate users still use Wasabi to spot sybil attacks.

In *theory* couldn't all their transactions be sybil attacks. All inputs except 1 for each mix come from them / known source. Every time the coodinator sees something coming in it has local wallets fill the rest of the space so to speak.

Yes there is a large cost and complexity. But we are talking millions of dollars at most, not an unobtainable amount of money for a business.

I also don't see that 866 number you gave on their site: https://myprepaidcenter.com/contactus

-Dave

What kind of a site only has tolled (paid) numbers for customer support and no email?
Obviously a scam site that knows that most people will not bother to spend money to make an international call when only 5-10 dollars have been stolen from them.

You have 1000s of posts here and you're VOUCHING for an obvious scam site? I just don't understand it.

VPN session or no VPN session, why would they display a blank card with no numbers? The attitude of the support email person at support@coinsbee.com has proven beyond doubt that it is a scam operation. This VPN excuse is the same one he kept repeating. I've never heard of a site working this way under VPN. I'll wait for someone else to respond before saying anything else.

Edit: I added a review on TrustPilot and now Coinsbee.com is trying to give an excuse that i purchased from some other site not Coinsbee. I have also emailed the actual company known as Pathward N.A. and we will soon know if myprepaidcenter.com is related to them or not. Obviously it is not and it is a scam.

coinsbee is also on the forum https://bitcointalk.org/index.php?action=profile;u=2667213

They (myprepaidcenter.com) have plenty of toll free numbers in the US. They are a public US / North American company and for the most part only deal with people in the US / North America. Most, perhaps all, of my US issued credit cards don't have toll free numbers out of the US so that is not unusual.

As for the VPN, since they are a financial services company they have to abide by KYC / AML rules. $1 or $5 or $1000 or $5000 or $100,000 it's all the same in the eyes of KYC / AML rules.

This is what I see when I 1st log in. [I blanked some info]


Once I click on view details I see the full info [I blanked some info]


What do you get when you click view details?


Pathward has nothing to do with coinsbee all coinsbee is doing is reselling their cards as do hundreds of other services.

With all the above being said, they are very very twitchy when it comes to security.

https://www.reddit.com/r/SwagBucks/comments/150olvk/stay_away_from_getting_myprepaidcenter_mastercard/

You see it as a $5 gift card I see it as a $5 card they (my prepaid / blackhawk / Pathward) *have* to see it as the potential to get 1000 x $1000 gift cards and move a $1,000,000 in less time then it took me to type this.

Nope, it's something on your side.
Bitrefill and many other places use myprepaidcenter.com for their mastercard prepaid cards.
Try a different browser. Also, they are US (possibly North America) only for some services. And they do block VPNs

https://bitcointalk.org/index.php?topic=5208530.msg61853963#msg61853963

Log out, log back in, try using a private browser window.

Heck, even a MC I got from a class action lawsuit was run through the myprepaidcenter.com site.
