It's also a bit of the 'pay me now or pay me later' theory.

Free trades. But high withdraw fees.
Free trades. But we sit on your cash transfers in for a few days and earn interest.
Free trades. But as NeuroticFish said the rates suck.
Free trades. But....you get the point.

2962  Bitcoin / Wallet software / Re: Coinomi wallet issues??? on: March 30, 2022, 01:05:04 PM
I just checked the advanced options of this wallet, and it turns out you can connect to your own node.
I don't have data obviously, but I would wager that an incredibly small number of Coinomi users do this though. If you are involved enough in bitcoin to be running your own node then you are very unlikely to pick a closed source wallet with significant vulnerabilities such Coinomi as your wallet to connect to your node. And even if you do, given that Coinomi is closed source you still don't know what other information or data it is leaking on the side or phoning home with.


Actually with any decent packet sniffer or logger you do know what is going back to their servers.

There are open source wallets like Mycelium that will leak more info then Coinomi.
With Mycelium you can't change the server it connects to without recompiling and with their ads that keep popping up they phone home about it if you click on them instead of dismissing them.

As others have said if you want a multicoin wallet they are all for the most part closed source.
If you want to vet a dozen different wallets so you can have an open source wallet for each coin you hold then feel free.

Standard you should not hold more coin in a hot wallet on your phone (or any other device) then your phone is worth....

Since there has been so little mention of it, I wonder how many users they really had.

Thinking about it with breadwallet being bought by Coinbase and btc wallet shutting down.
I guess more and more businesses are getting rid of the free services that they can't figure out a way to monetize.

Selling at a loss and making it up in volume only works for so long ;-)

2964  Other / Meta / Re: Suggestion: remove spam 180,000x: hide Website links for users with 0/1 posts on: March 29, 2022, 01:28:41 PM
A simpler proposal would be to remove the website link until you become a Member.
I tried not to raise the bar too high, but I'd be totally fine with this too Smiley

Still not sure between Jr Member or Member but sounds like a decent proposal

How about member or Jr. Member + Copper?
Copper is cheap enough that it's not a big deal for someone who is going to be even a casual member of the forum can pay for it.
There really is no reason for anyone to need to post website links, it's a convenient thing but not needed.
So either be useful & post and get merit or pay a bit.

2965  Bitcoin / Wallet software / Re: Bread Wallet now Coinbase Wallet - help needed. on: March 28, 2022, 11:11:59 AM
From what I am seeing there are 2 issues going on.

1st is that it looks like they did not get the derivation path correct. Which seems odd, since it IS working for some. So along those lines is it just checking a lot of paths to find funds.

the 2nd and this is a guess is that it's really slow to show the funds, as in stupid slow because it does not show them till it's done.

Since this is a non custodial wallet and it's only connecting to 1 set of back end servers to scan I am wondering if they are just overloaded since a lot of people saw the announcement and started migrating over the weekend.

If it's going through every derivation path and you have a lot of transactions I can see it taking forever. Which is why some people are seeing funds and others are not.

It's not like electrum where if it has as issue with server x it goes to server y.

And you can't have this conversation in a "bubble" so to speak.

If all we were discussing is theory then yes. But in reality, you have the cost of the turbine, the setting up and and wiring of the turbine into the power of the facility, the maintenance of the turbine and many other things. Will you ever generate enough electric to offset the cost of it or even come close?

There's a probability of more than 50% of hashrate being from Asics
...

As I said above, depending on what estimates you look at and who is doing the math it's between 70% to 85% ASIC.
Although the numbers were from last summer I don't know why they would be different.
No proof, just what large miners were saying they were using.

Who the fuck told you that? Citation needed.

It is also a lot about perception.
Good or bad, right or wrong for a lot of people they see all the alts as copycats.
Some might even have better features or a better way of doing things but in the end there will always be someone shouting it's not Bitcoin.

It's not like you are talking saving 100s of GB of blockchain data, it is barely a few megs of storage, not like people are saying you have to save something big and expensive to store.

2970  Bitcoin / Project Development / Re: [BACK ONLINE] Bitcoin block data (665 GB): inputs, outputs and transactions on: March 27, 2022, 11:19:24 AM
...I believe you have previously stated that you don't want to use AWS because you don't want to have to use a credit card to pay, nor associate your IRL identity with the service. My argument would be that this is really your only option, as using a VPS with a smaller provider (as you have been doing) is eventually going to result in your account being shut down, or your bandwidth being exhausted...

Not unless he is working with a really small provider. More and more 1GB un-metered for co-location is the standard.* Or if it is metered it's in the multi TB range.
Bandwidth has gotten so cheap at data centers that it's pointless to rate it anymore. Case in point, Cogent just made us an offer for a 1GB fiber loop to our rack for under $400 a month all in. 3 years ago that same circuit was well over $1500. Hurricane is under $2500 for a 10GB circuit. And we are a very small buyer of bandwidth. "Real" companies that are buying multi 100GB circuits are paying very very little.

-Dave

* Most places are going for a 10 to 1 over subscription so you probably may not get the 1GB all the time but the point is the same.
It is unlikely that Loyce would be dealing with Cogent directly, but rather would be dealing with one of Cogent's customers.

Even if someone's bandwidth is "unmetered", I can assure you that usage is still "monitored". As you note, Cogent is going to oversell their capacity, and most likely, Cogent's customer who sells VPS services will also oversell their capacity. If Loyce is constantly sending hundreds of GB's worth of data to the internet, there will be less capacity for other customers to send their own data to the internet, which will degrade service for others.

The files that Loyce is hosting total over 660 GB. It would not take much for Loyce to run into hitting the multi TB range with files of that size, especially considering that it is trivial for someone to request those files multiple times.

Cogent and most providers like them as a rule do not oversubscribe, if anything they under subscribe.

They used to do it, but stopped around the GFC. No I don't think it's related, but around 2007 - 8 - 9 we just stopped seeing it, at least in the major DCs. I think there are just too many competitors. I can call Monday AM and have an agreement in a couple of days with another provider have the fiber connected a couple of days after that and be running a couple of days after that. So if I don't get my 1GB you're gone. Heck when Sandy took out people in NY loops were being turned up in hours as we all ran around the DCs getting stuff wired.

The people they sell to oversubscribe what they bought.

If you use a storage bucket on AWS or GCS, someone will need to pay $0.09/gb to transfer the file to the internet, or $0.01 to transfer your file to another data center run by the same cloud provider located on the same continent where your data is housed (or $0.00/gb -- free - within the same datacenter location). You can configure the storage bucket so that the person downloading the file will need to pay the transfer charges.
Up to $60 to download a few files. No wonder Bezos is rich Cheesy

Till we got out of that business we used to joke Amazon is our best salesperson.
Their product is good, don't get me wrong, but it's super expensive and most people don't need it and a 2nd or 3rd tier provider is usually fine.
Not to mention, if your provender is not peered fast enough with Amazon they tend to be super slow since they prioritize amazon.com traffic over the aws traffic. In most major markets it's not a big deal. But in the middle of nowhere when your local ISP only has a 10GB connection to the peering network come Christmas time it can get bad.

Either way this is drifting from the main point of the thread, so I'm going to leave it alone for now.

Side note, do you know how many people are actually using this data, it's neat and all but outside of the geek-base on this forum I don't see a lot of people caring.

OK, how about 99.999% sure they are going to loose the advertising portion of it.
This has been around the block a few times already (adult services / adult content / certain weapons / I'm sure other stuff I do not remember)
And every time it's come back to they can limit what they allow people to advertise.

2973  Bitcoin / Hardware wallets / Re: Be careful what you plug your hardware wallet into your PC with on: March 26, 2022, 08:18:14 PM
It would also get them into big legal trouble if they don't make a responsible disclosure. In cybersecurity it's either that, or selling the exploit.
I wanted to say that as well, but I couldn't remember the damn term Grin. Responsible disclosure, that's it. Dave doesn't seem to me like the person who is looking yo exploit this, otherwise I don't think we would even have this thread. His post above confirms just that. Dave also doesn't know how it works. Only the person who discovered this bug knows the specifics.

Apple = "It's not a bug, it's a feature"

Seriously, it's not a bug.

You are plugging something inline between your PC and your hardware device that can manipulate data. When HW wallets were 1st made there was no way that a device with all this storage and Wi-Fi could be put into a cable that does not look any different then a regular cable.

So, it's just a vulnerability not a bug. In the real world it's the same thing to the end user. Dealing with security discussions it's different. A bug indicates they made a mistake, a vulnerability is something they do not defend against. To most of us it does not make a difference.

To others it could cost them their job. A bug is "what the f--k were you thinking, get out of the office you idiot" a vulnerability is "This came up can you fix it or code around it"

-Dave

2974  Bitcoin / Hardware wallets / Re: Be careful what you plug your hardware wallet into your PC with on: March 26, 2022, 03:43:46 PM
If he can get it working, it will be disclosed to them with an "X" number of days to acknowledge the issue and discuss with him.
The trouble is, it's not vulnerable until the user plugs in a malicious piece of hardware inline with their device. So, there might not really be a way to fix it if what he thinks is happening, is really the way it works.

It's like using a wireless keyboard to type sensitive information. There may not be a way to fix it.

As for what is working now, i.e. change an address in a known location that the user copy & pastes. There is nothing to really disclose. This device can run an app that can create predefined keyboard inputs. Short of unplugging the power to your PC it can't be fixed.

Edit to add: if it can't be fixed, it will not be given out or discussed (even to me and I'm the one who paid for the damn cables to test with)
If it can be fixed but they don't want to or just don't I'm not sure.
If it can be fixed and they have a timeline it will not be disclosed till after an agreed upon time has passed.

It always comes back, but all the other channels I have stay up. Just trying to figure out if it's you or me or just something between us.
OK....that made it sound like we are in a relationship....

They are going to loose.
1st of all the suit is way too broad
2nd the TOS for advertisers is 'we can not do business with you if you don't feel like it' has been held up in courts all over the world already.
As for the banks I really can't comment.

Now will they settle 1st is a tough question, but as someone once pointed out to me, these big businesses can crush you with their legal teams. BUT the big legal teams do cost a lot to run so at times even settling in the 10s of millions is cheaper.

I don't understand this however. You're breaking encryption now? Why?

Once again, I'm not he is :-)

But he is not sending the bad address to the device, that is the issue. The user can copy / paste the info, but leaving the manufacturer out of it, there is a browser plug in they use to talk to the hardware wallet.

As of now THAT is not fooled by the find / replace on the web page since it sees it as it loads or something. Explained to me but as I said I lost it after the 1st few minutes of the explanation.

Just so you know how dangerous devices like this are here are just the PUBLIC DOWNLOADABLE things you can load on it.

2978  Alternate cryptocurrencies / Mining (Altcoins) / Re: ETH mining nearing end of life - When will you liquidate your rigs? on: March 25, 2022, 02:43:45 AM
I think the main point that you are missing is that depending on what estimates you look at between 70% to 85% of ETH mining is done by ASICs not GPUs
So yes, there will be TONS of GPUs coming into the market but it's not like it's even a significant portion of the hash rate. AND most large mining farms are using cards w/o outputs like these: https://www.tomshardware.com/news/sapphire-radeon-x080-and-x060-rdna2-mining-cards-spotted so even if it is 30% GPU mining a large portion of them can't be used for anything else.

The home / hobby / small miners can and probably will dump their GPUs to a certain extent, but it's not going to be a free for all. Since home / hobby / small miners may or may not want to do other things with their cards. Be it mine other coins, or do vanity searches or game or run folding at home or....

No idea why you are thinking that.
Looking at whattomine.com there are still 6+ coins that are close to ETH mining profits.
And another 15 or so that will still generate some good money.
At a guess those will get crushed, but some others will probably come back up.
Monero and similar are my guess.

Not going to worry about it.

FYI there are dozens of similar posts about this very thing if you want to search a bit.

2980  Bitcoin / Hardware wallets / Re: Be careful what you plug your hardware wallet into your PC with on: March 24, 2022, 06:39:07 PM
Looks like there's a new reason to keep an extra PC/laptop to interact with crypto. Of course, with USB type A, even then no adapters are required. This means that the threat described in this topic will be excluded.

USB A can easily handle exploits for PC/laptops, see the link from my other post here.
So by making the wrong assumptions, instead of protecting one, you can end up getting malware on the other.

More and more manufacturers are refusing to use USB A in their devices, and over time this will lead to a shortage of such devices. The market for used devices will not be endless either.

This doesn't really make sense. USB A is still widely used for PCs, I don't think they'll get no-longer-produced too soon. And, if you want to, you can easily buy cheap and straightforwards adapters from USB A to micro USB or USB-C like this one:



<Cough> MacBooks </cough> And any of the ultra portable PC ones (Microsoft surface, etc.) are all USB A only.

Having one of those small adapters is nice. But people are people, and people forget things.
If I drop a few of those cables around a show like BlackHat or Defcon probably nobody is going to plug them into anything.
Leave a few around Bitcoin Miami and you could probably get someone to plug them in.

Buy a few dozen (yes it's expensive) but then put a logo on for something that looks like a giveaway and you know people are going to use it....
