2261  Economy / Service Discussion / Re: Bitrefill's new bill pay service on: September 24, 2022, 09:37:21 PM
So there was an issue with a payment that I didn't catch when it was made, I just noticed after a few days and want to look and saw that the payment had not hit.
Sent them a message and they refunded my payment to my BTC balance. Took under an hour, so A+ from them on that.

Been using the service on and off for the last 5 months or so with no issues besides this one so if you are US based and don't mind KYCing with them I fully recommend it.

I have been seeing it more and more with larger and larger amounts on some of my long term cold wallets. I figure if I ever move the funds I'll coin control all of those funds someplace else.

At a guess, it is a dust attack for some reason BUT they know that people in order to have more privacy will ignore / leave the truly dust amounts. But make it more money and they may actually move it someplace where they may have be able to trace it.

Yeah, I know, sounds paranoid but it's the only thing I can come up with.

...$5 wrench...


I have always thought a good idea for a wallet to get around the $5 wrench is a fully functional dead man switch.

Enter THAT pin / password / use that finger and the wallet unlocks normally. IF ANY transaction is attempted to be sent, all the funds are sent to a per-determined address with a high fee, non RBF. I mean at that point it's only going to get you hit some more with the wrench but at least they don't get the money.

Interesting to see where this thread has gone in terms of the discussion.

...His law team are well aware of this scam but now they have no other choice than to continue playing this circus show with him as a main clown....

So long as he or his benefactors keep paying I don't think they care. Makes you wonder how many cases are in the courts because the lawyers involved are just taking all their clients money because if they don't they know someone else will.

As for everything else, it's obvious that they are bad forgeries but it's also obvious that BSV is a scam shitcoin and people keep flocking to it, so there is that side too.

Hopefully the judge nails CSW to wall so to speak and we can all move on.

2265  Bitcoin / Bitcoin Discussion / Re: Chainalysis software puts the lie to the idea that Bitcoin guarantees anonymity. on: September 24, 2022, 10:58:07 AM
Companies that do chainalysis are more or less providing a service that anyone with enough time and money can do themselves.
Anyone can follow transactions on a block explorer and follow notes to known addresses for exchanges and people.
Add in getting the information from other centralized services and it becomes more difficult. But still possible.

What they do do is provide 2 things.

1) A nice PR for the government agency when they show they are protecting you by hiring people to find this stolen, or obtained through fraud or whatever BTC

2) They are the fall guy when they get it wrong, "We didn't do anything wrong, we hired the best company we could find"

2266  Bitcoin / Bitcoin Technical Support / Re: LN - peer refuses connection on: September 24, 2022, 02:07:33 AM
It is like that for at least 12h. OK, not a big deal, I will try tomorrow.
Hard to say, is it better to trust a giants or smaller peers...

I have some channels open to other places that only have a few other channels and not a lot of funding, and some other places that I have channels open to 100s of channels to other places and a lot of BTC.

Having a lot of different ones open allows for a bunch of possible different routes. The larger places tend to have higher fees where the smaller ones tend to be less costly.

Still talking only a small amount of BTC in fees in the end, but still....

2267  Bitcoin / Bitcoin Technical Support / Re: LN - peer refuses connection on: September 23, 2022, 09:03:56 PM
How long has it been down? They may be having issues. The last update it made to 1ml.com was 14 hours ago from when I am posting this:

https://1ml.com/node/0242a4ae0c5bef18048fbecf995094b74bfb0f7391418d71ed394784373f41e4f3

As a rule, a node with that many channels and transactions and 37+BTC tends to update a bit more. Not a definitive answer but a possibility.

I can connect to is as a peer but it will not let me open a channel. So, I am *thinking* it's them but it could also just be us.

2268  Economy / Exchanges / Re: An interesting thought / discussion about exchanges without KYC on: September 23, 2022, 06:56:42 PM
Back in the early 2019 I sent pretty decent amount of stablecoin to Binance in order to stock up on bitcoin, and while waiting for the right time to buy, my mobile phone died leaving me without the access to Google authenticator.
I don't know what you are doing now with your 2fa codes, but I would suggest switching to Aegis app (instead of Google authenticator) and doing backup on different device like your computer.
You can even use KeePass as reserve option for storing backup codes in case something happens with your phone again.

At least for me I now have more secure backups of my 2fa info for important stuff. But, it took destroying 2 phones back to back for me to figure that out.

But, I still wonder if for some reason KYC works for people and they really don't mind it or even prefer it.

Let me be clear, I don't like KYC I don't like regulation. I also fully understand, and have even made posts about how some people do prefer it. I am really trying to figure out the mindset of people that do.

I can disagree without saying they are wrong, just that we have different views. But, I really find some of the views interesting, some in a way I really can't fault, if it works for them.

2269  Bitcoin / Press / Re: [2022-09-22] JPMorgan CEO Jamie Dimon slammed crypto and called BTC Ponzi Scheme on: September 23, 2022, 01:12:11 PM
So all of this nonsense was for promoting their own shitcoin and he forgot to mention they can easily freeze/confiscate it!

He also left out the fact that JPM offers BTC / crypto to is clients.
Makes you wonder if that leaves them open to a big chunk of liability if something bad happens.

i.e. DaveF is a JPM client, he invests in BTC, Jamie Dimon says it's a Ponzi, BTC drops a lot, DaveF looses money when he sells, then calls lawyer saying JPM let me trade in something they said was a Ponzi, I would like to sue them now......

May not win, but enough people file enough lawsuits about it, that could become a PR nightmare.

2270  Economy / Exchanges / An interesting thought / discussion about exchanges without KYC on: September 23, 2022, 11:40:31 AM
So @Ratimov started this thread: https://bitcointalk.org/index.php?topic=5414539.0
and in it and @BitMaxz https://bitcointalk.org/index.php?topic=5414539.msg60990161#msg60990161 made the comment about needing to KYC himself to regain access to the account.

Since I did not want to clutter up that thread with a tangent discussion I opened this one.

So, eliminating the exchange blocking you, it's something you did, how far would would you go down the KYC path to get access back to an exchange account for how much money?. And would it matter about the exchange. Taking CoinEx they have been around for years and have a fairly good reputation, I would be more willing to give them some info about me then some other ones.

Discussion point 2, dealing with KYC exchanges do you think / have you found things like account recovery would be / are easier? Eliminating the Coinbase sucks part of this, I lost access to a few things due to having both of my 2FA devices die almost back to back. With anyplace that knew who I was due to KYC it was easier to get access back then those that did not. A few places I just abandoned and re-created accounts since I had no funds in them. But, I am only a single data point, just wondering about other peoples feelings and experiences.

2271  Economy / Exchanges / Re: Someone Sent Me Some Coins, Could Be A Mistake on: September 22, 2022, 02:58:58 PM
However, its 24 hours and no one has indicated that they paid for a service.
[~snip~]

Update:
Someone said it could be a phishing attempt in the comment. It's not. I have actually checked the exchange wallet and the fund is there.

I was expecting it's phishing. You say it's not. OK.
I was expecting that if it's for real the customer will contact you in a few days. I see he didn't.

One thing that comes to my mind is that you can check on the blockchain if you've received in the past money from that same address (although most wallets don't reuse addresses).
Another thing would be you simply send back the coins to the address you've received from.
Or you can wait until the one who made the mistake figures it out and contacts you (but in that case, as said, he has to prove ownership of that address).


Is it a big amount?

I would not just send it back to a random address. If it came from and exchange or any centralized service it's just going to go into their hot wallet.
Yes, by jumping through a lot of steps it might be recoverable, or they may just say thank you for your donation. The staff is getting beer & pizza on you tonight.

If the OP has not been contacted at this point, I would treat it as the same think, a donation.
Assuming it's not for a life altering amount of money, then I would sit on the funds for a while before spending them. No, they are not obligated to give it back, but it's still the right thing to do.

*Also keep in mind, 'life altering amounts' vary from person to person. So there is that too.

2272  Other / Meta / Re: BSV subforum on: September 22, 2022, 02:35:31 PM
I think it would be better just to eliminate all PRO BSV people / threads and just leave the ones ridiculing how bad it is. Don't even give them the opportunity to have a voice here.
Make it perfectly clear that it's a scam / con and although the forum does not moderate scams / cons this one time it's so bad and the perpetrators of it are so scummy that they are not allowed here.

This way we are showing one voice as to how bad they are, and we are not wasting time trying to shout over the trolls / shills.

There are some things that I disagree with and don't like that I can just ignore, once you get to this stage there is no reason to even let them exist here. At least in my view.

2273  Bitcoin / Bitcoin Discussion / Re: Hodlonaut Trial on: September 22, 2022, 12:01:46 PM
I have mixed feelings about the 7 week delivery of the verdict, is it not obvious to the judge
of the above?

A quick verdict may look rushed. Justice is famous for taking its time.

I don't know how the costs thing works, but I'm afraid CSW may try to drag it longer by dragging the completion of costs documents.
Even more, the Nov 8 may be the "upper limit" and the result may come earlier. I hope so.

How much is paperwork and procedures that just take time. The decision has been made, now it must be written, proof read, documented, references cited, those references checked, approvals from others, and so on. It seems to be the same in a lot of courts, when it's major and important and you can pull in a bunch of people things can get done quickly. For things like this, although *we* think it's important, it really is just another case and it gets done when it gets done.

For now we can only sit and wait.

Since I only really know US courts and how long they take I can't comment as to that amount of time in general being fast or slow or average.

I recognize the IP, so I would say Bitcointalk uses a dedicated IP with the mail system.
However, an IP listed as "evil" is not blocked but just moved to the spam folder. That has always been the case with my previous email and the current one.

It depends on the service and how they weight spam. Are they just using a few blacklists or are they running SpamAssassin and Cyren and Message Sniffer while using the reputation of other IPs in the subnet? Do they run enough tests to say, 1 to 4 fails it's delivered 5 to 10 it's put into spam and 11+ it's blackholed.

Since you are getting SOME I can see them running some word / pattern matching and if it fails it's either bounced or dumped.
I would ping out to theymos to see if he can get you the SMTP logs from the delivery server, if it shows as being delivered to your provider then you can reach out to their support, if not then theymos / staff have to fix the problem anyway. We can talk about it here but we can't really fix it....

2275  Bitcoin / Mining / Re: Energy storage solutions? on: September 21, 2022, 05:50:37 PM
Most lithium-whatever other chemical stuff car batteries have a lifespan of over 1500 cycles. That is usually the base number.
Obviously the way they are used is going to matter along with temperatures, charging speed, and a lot of other things.
And there is a market (at least here) for the used almost dead ones. So I think the $0.20 is high.

Over 1.5k cycles by how much? Double? Then the price will likely be double as well, i qouted prices from the local markets, could not find any large lithium battries here, but if anyone knows how much the 100a battries go for and check their specs for number of cycles, we can run a different math which i am pretty sure won't result in a very different value.

You are right about dead battries, we sell them here too, for like 10% of thier prices as new, they buy them based on weight not capacity or anything else.

Depends how you use them.Lithium batteries have a certain amount of charging cycles before they really start to loose capacity. But that is for full discharges. Partial discharges are proportionally less of a burden on the pack, and no one does full discharges ever if they avoid it. So If you over design what you need, you will obviously pay more. But this is where you need a lot of math. Paying 2x up front to get 3x the lifespan may be a good deal for you. Paying 4x up front for 10x the lifespan for someone else might be better for them.

The recycling depends on composition of the battery. Figure anywhere from $0.12 to $0.40 per kilowatt hour for large recycling (read tons and tons) for smaller amounts it's by the pound.

So every KWh of battery storage costs about 300$, and every cycles wipes out 20 cents of that value ( best case scenario)

Most lithium-whatever other chemical stuff car batteries have a lifespan of over 1500 cycles. That is usually the base number.
Obviously the way they are used is going to matter along with temperatures, charging speed, and a lot of other things.
And there is a market (at least here) for the used almost dead ones. So I think the $0.20 is high.

The efficiency of the charging and discharging circuits depends on how much you spend. Like many things you can spend a lot more money and get some charging equipment that is well over 90% efficient. Or you can get get generic crap that is a lot less. Same on the output side.

Pay now or pay later.

2278  Bitcoin / Bitcoin Technical Support / Re: hdd cache software, to allow running block storage on less costly disk on: September 20, 2022, 12:08:16 PM
Good lord. HDD cache software is still being sold?

Such oil snake software (which have small impact or has unmentioned danger, while also collect your personal data) still has place today. IMO the worst offender would be game/FPS booster.

Going to disagree with you both a very very little bit on this. 99% of the time you are right.

For the most part for it's crap and does nothing. However, you do have to put in a 'but'.
On older systems, with slower hard drives, and yes there are a ton of machines out there with 5400RPM drives, it does help.
And keep in mind some OEMs made PCs with 1TB 5400 RPM drives with no onboard cache to meet a price point.
Today, 4GB sticks of DDR3 RAM are very cheap to the point that a lot of IT people just give it away since it has no real use at all anymore.

So in the situation of old PC, slow crap drive, free extra RAM. Yes it does help.
And you don't have to buy a better drive or clone your old drive or do anything like that.

Like I said very limited good comes from it, but not zero at all times.

Looking at: https://coinmarketcap.com/exchanges/crex24/ it appears their API is still handing out info.

So doing a little more digging about their API I found: https://api.crex24.com/v2/public/orderBook?instrument=LTC-BTC&limit=2
and
https://api.crex24.com/v2/public/currenciesWithdrawalFees?filter=BTC,LTC

They do give out information. Even to my IP in the US.

In theory, if you have API Access, and set it up properly, you can also withdraw coins. So it's possible some lucky people can still get their funds out.

It is possible some people or bots are still out there using / trading here with no clue that the exchange is gone.

2280  Bitcoin / Development & Technical Discussion / Re: Less private but perhaps secure HOT wallet on: September 19, 2022, 03:59:44 PM
Would people want one that has some 2nd form of authentication that could probably be used to identify you, but in the event that the device was compromised not allow funds to be sent.
This already exists by using Electrum's 2FA via TrustedCoin. However, having both the wallet and the 2FA app on the same device is meaningless, as explained below.

Kind of like it only sends it's transactions through a certain set of servers, and after you create and transmit the transaction you have to then do a quick login and approve.
If someone can compromise the wallet on your phone, then they will almost certainly also be able to compromise your login details for a website you access via your phone (which, to be honest, 99% of users would simply save in their browser's built in password manager anyway), or your 2FA app.

I don't see how you can make a hot wallet on a phone any more secure without requiring a second physical device, be that another phone for multi-sig, a hardware wallet, or even a hardware YubiKey or similar for 2FA. Any 2FA using the same phone as the wallet itself, be that a code, a login, a second wallet, receive an email, etc., adds almost zero additional security.


We were discussing the possibility of a wallet app that would not let you save the login / password. So every time you wanted to send you would have to enter it. There are a lot of security apps out there that generate an onscreen keyboard that you have to use to enter the information so keyloggers would be pointless.

I don't know if there is a way to do it really securely, but was wondering what everyone else thought.

Personally, I treat my hot wallet like cash. It's risky to carry a lot around, but still nice to have it with you if you need it.
