We been away due to covid infection,

We apologize as our whole establishment was severely effected

Actually there was no issue from our side balance, we have balanced our accounting sheets
please PM and explain the nature of your concern

Sorry to hear you were ill. I do hope you feel better.
This being said: your site showed a daily updated "canary" telling your users everything was ok, while it was most certainly not... I assume this canary is fake then? I mean, if it automatically updates, it has no value whatsoever: you could have been in jail whilst your canary kept telling your users everything was fine.

I hope you can work things out with the people that have filed a scam accusation, i'm willing to delete my negative trust as soon as everything is worked out, and the alleged victims confirm their accusation got solved.

I'd go with DdmrDdmr's sollution first, and if it doesn't pan out, you can always try twitter: the reseller (bitxatm) does have a twitter account: https://twitter.com/bitxatm
This being said, they did not retweet anything since 2017, but if you send them a DM, the original owner might (or might not) still get an e-mail message alerting him/her of your DM, and he/she might (or might not) be willing to help you out.
But like i said: it's a longshot...

EDIT: after thinking about your problem: can't the person who sold you this item help you out? The odds are that it has a fixed network config and isn't using DHCP, and it might not be able to reach the internet due to your LAN's setup (hence, give you the message it's not connected to the internet). Also, the person who sold it to you should be able to provide you with info about passwords (and network config).

 I got more confused by "guessing a random number"  Huh

 anyway tink about a website that you could go on there and guess a random number, and if the number is correct you will get 100k?  (no gamble the random number will be used to mine bitcoin)

 thats another idea BTW

  not asmbling but desining one

No offence, but you should really start by reading (and understanding) the whitepaper before you start thinking about building a custom miner or a website where your users enter a nonce... Really, you're more than welcome to ask us info, but if you don't start by really understanding how the blockchain works, and how POW fits in the picture, you'll probably never 100% understand how this stuff works... And, well, building a custom miner or a site like you're brainstorming about without 100% understanding what you're actually doing won't result in much...

no, no real problem... you're allowed to have as many alt accounts as you want, as long as you don't abuse them.
This is even less of a problem, since it's not an alt account but rather a second account using the same ip.

So, like i promised, i tried letting some video's play in the background again... This time for >1,5 hours... I ended up getting about 10.000 cashtoshi's. Much more than the first time, so it does indeed seem like there is no direct correlation between the number of videos, the time spent and the payout.

I wanted to review the withdrawal process aswell (having 10k cashtoshi's) when i noticed the following: are you really using a 300.000 cashtoshi fixed fee? Really? Why? Your users will have to watch > 60 hours just to afford the transaction fee...

BCH has blocks up to 32 Mb, it's very rare to see one that includes more than a couple hundred transactions... I have to go quite some blocks back to see one that is bigger than 5 Mb. There simply is no need to pay more than 1 sat/byte, while you are paying > 1000 sat/byte (unless you're aggregating hundreds of small, unspent outputs, but still a block can only contain 32Mb of data, and you're paying for a 300 Mb transaction @ 1 sat/byte... And the odds are you won't be allowed to broadcast such a transaction anyways).

Why don't you use dynamic fees? I can only assume you're running a node to handle payouts? doesn't bch have the 'estimatsmartfee' json-rpc call? If you don't have a node running, i'd probably go for a 2 input, 2 output tx => ~400 bytes = 400 cashtoshi fee (at 1 cashtoshi/byte).


Fun fact: did you know the BCH "owners" at one time tried to implement a forced tax of >10% on their miners, promising to exclude miners that didn't pay the tax? I wouldn't overpay on fees, especially not for BCH

So you'd have to watch porn non-stop for 41 hours to reach an amount you could potentially withdraw (about half an eurocent, not taking tx fees into account).

Wrong the site pays out more than this usually. Remember, earning are dynamic. Currently, the site is paying 0.00001 BCH= USD 0.006233 with a couple views. Everything is based on traffic. That is why its so difficult to pinpoint how much one can earn when things can change in a second

Well... earnings might be dynamic, i'm just explaining how much i watched and how much BCH is in my account... Wich is 0.0000002 BCH (20 sat's) for watching 5 videos... It's possible that other people will earn more, or less depending on parameters you've set, i'm defenately not disputing this. The fact of the matter still remains that this is what i got.

Just to be fair to you, i'll leave my cellphone on again this evening or tomorrow and let it stream 3 or 4 more video's and report earnings afterwards... It's true that one measurement might not be enough to base conclusions on.

Each to his own tough, you're more than welcome to do whatever you want, it's your site anyway Smiley

Jammer genoeg heeft binance zijn SEPA withdrawal tijdelijk uitgeschakeld... Hoewel... 't Is nu toch al wel een tijdje, dus ik vrees stilletjesaan dat het voorgoed is...
Als je je bij hun verifieerde had je een withdrawal limit van $2.000.000/maand (en $200.000/dag). Ik heb hen reeds een aantal keer gebruikt in het verleden, en dat ging steeds vrij vlot. Persoonlijk vond ik hun fee structuur ook best meevallen (ik denk dat het 80 eurocent was voor een SEPA transfer, en de tradefee was ook best wel laag), maar zoals eerder gezegd: de SEPA withdrawal is dus al een tijdje gedisabled.

Ik ben dan maar overgeschakeld op coinbase pro (hoewel ik ze nog niet gebruikt heb, maar ik ben wel geverifieerd). Op mijn 'limits' pagina zie ik dat mijn dagelijkse limiet 250.000€ is, de maandelijkse limiet kan ik echter niet zien.

Kraken zou ook nog een redelijk alternatief moeten zijn, deze hou ik als backup voor als de fees van coinbase pro me toch te hoog zouden blijken.

Het jammere aan heel de zaak is wel dat zulke exchanges eigenlijk steeds een KYC procedure vereisen, en dat niet alle banken even blij zijn met deposits vanaf een bitcoin exchange... Eerst goed nakijken of dit bij jou bank het geval zou kunnen zijn dus! Maar eens je de KYC procedure doorlopen hebt, en je geverifieerd hebt of je bank crypto vriendelijk is, zouden bovenstaande 3 exchanges je toch in staat moeten stellen om ettelijke miljoenen per maand om te ruilen van EUR naar BTC (en omgekeerd), dat noem ik toch al redelijke bedragen Wink

Als je zonder KYC wilt werken, of cash wilt verhandelen is het een héél andere zaak... Zelfs sites zoals localbitcoins vereisen tegenwoordig KYC... Dus zonder KYC is het toch wel even moeilijker, dan moet je op fora of via meer obscure sites kopers (of verkopers) zoeken en fysiek gaan afspreken... Persoonlijk zou ik het je niet aanraden, je zou zeker de eerste niet zijn die beroofd werd, of waar de politie ineens opduikt...

I get the sha256d part but how can I broadcast my hash to other the nodes?

Well, you'll probably have to run at least some kind of daemon... You'll need to connect to other node(s) and then send them your block. More info can be found here: https://en.bitcoin.it/wiki/Network

If you'd run the reference client node, you could use the submitblock json-rpc call... it seems chainquery does not support this call: https://chainquery.com/bitcoin-cli/submitblock

I don't know any online tool or service that offers this feature. If you read all protocols, you'll probably be able to build a much lighter client, one that only connects to other nodes and relays your block, but i don't think this is something you can do using binary's available on your OS, nor do i think there are sites out there that'll help you with this either.

Now, just to be 100% sure, this is all for learning purposes, right? Cause, there's no way you can actually pull all of this off IRL... You have allmost no chance of solving a block using a latest gen ASIC, let alone an older ASIC, let alone a FPGA, let alone a GPU, let alone a CPU... So your odds of solving a block, even if you'd find a good nonce by pure miracle, are 0 (since there's no way on earth you'll be fast enough generating a block, a block header, a sha256d hash and broadcast it in the ~10 min window)

Now, i know those payouts probably aren't all that high, but i still was disspointed with 20 satoshi's (that is, BCH satoshi's, at an exchange rate of ~540€/BCH)... I mean, that's an equivalent of 0.00011€, and those video's played for at least 40 minutes... So you'd have to watch about 50.000 video's to reach 1€.
I'm surprised there's no dust limit on BCH. This 0.0000002 BCH isn't even enough to pay the fee to send it, it's literally worthless dust and would cost more than it's worth to use.

I might have made my previous post a bit confusing tbh... It was an offchain (internal) transaction (that's why i put it between quotes), so my account information now shows a balance of 20 satoshi's, but i haven't withdrawn them yet... I can only assume i'll need at least 1 sat/byte as a fee, and there'll probably also be a dust limit... So i guess you'll have to have a balance of at least 500-1000 sat's before you can withdraw? This would be an equivalent of:
20 sats / 5 video's = 4 sats/video.
1000 sats / 4 sats/video = 250 video's

The video's i let play were all a little over 10 minutes/piece, and i let them play completely, including the adds that play before the video start... So a better guess would be that i let them play for ~1 hour.

250 video's * 10 minutes/video = 2500 minutes = 41 hours.

So you'd have to watch porn non-stop for 41 hours to reach an amount you could potentially withdraw (about half an eurocent, not taking tx fees into account).

You're right.

"Did somebody sell you a wallet.." - no. To one of my relatives, long ago.

It's a shame... The world is full of scammers i'm afraid. This is also the case with the crypto community. Scammers love to use new technologies that are not that well-known to lure in their victims.
I truly hope your relative didn't pay to much for these wallets... The odds of actually buying a real wallet with real funds inside for any amount (but certainly for an amount lower than the wallet content) is very close to 0. You can investigate further, but the time and effort your spend are almost certainly in vain, since this is a very common scam tactic that has made hundreds of victims over the years. It's the online equivalent of somebody selling you pieces of inked paper and a special chemical with the promise the inked paper is actually smuggled in money that has been inked all over, and the chemical can be used to convert it back into real money...

I've heard that at Doge's last ATH. But one may be able to convert/exchange to another coin of preference before withdrawing.
The point was to use a way to show the users they are earning something, anything more than 0. And the more expensive coins are not suitable for that.

At a second thought, another direction could be to show more (10? 12? 15?) digits after the decimal point for a "cheaper to withdraw" coin.

Well, as an addendum to my test:  a while after "watching" a couple of video's on my phone (in reality, i just pushed "play" on 4 or 5 video's and let them play while i was working on my laptop in the meantime) i received a mail from the site that i got an incoming "transaction".
Now, i know those payouts probably aren't all that high, but i still was disspointed with 20 satoshi's (that is, BCH satoshi's, at an exchange rate of ~540€/BCH)... I mean, that's an equivalent of 0.00011€, and those video's played for at least 40 minutes... So you'd have to watch about 50.000 video's to reach 1€.

I still think it's a good idear the OP has, but at the moment i don't think i'll be a regular visitor, the amount of video's on the site is lower than the amount of video's that i'd need to watch to scrape together 1€.

Anyways, @OP: good luck with your project.

Thanks for the info!

Situation indeed.. I am talking about two wallets with these addresses:

https://www.blockchain.com/btc/address/173bU1NZtrnxfXdVQFXsRp22nuc6fEmB4k

https://www.blockchain.com/btc/address/1NFx9FETuduha8qJ6ehPYufTqVirB1Jf1D


Also, talking about the 173bU1NZtrnxfXdVQFXsRp22nuc6fEmB4k address, which had no outgoing transactions until recently. But how could one forge a wallet, which has no outgoing transactions? o.o


Well... To be honest, i don't quite get your question.
The two addresses in your post did indeed got funded in the past, and some of the outputs were spent. This basically means that somewhere out there, there's a wallet that contains the private key for these addresses (i take the term "wallet" as a broad term, it might be just a paper wallet containing nothing more than said private key).

As to how one could forge a wallet... well, for one, it has little to do with outgoing transactions to be honest... A thief could (potentially) create a wallet, encrypt it, use it, and at one point edit it so the private key inside said wallet so it is replaced by a fake private key. This way you could open the wallet, look at the available funds, look at the transaction history, but if you'd ever be able to decrypt the wallet, you'd notice the private key is, in fact, fake... So you cannot spend those funds.

It's also possible to give somebody a wallet with watch-only addresses by not importing the private key, but merely importing the address. This way, the wallet will be able to parse the blockchain, generate a complete history of the watch-only addresses inside the wallet, but since it does not contain any private keys, you cannot spend those funds.

Not all of these methods are possible with every wallet implementation tough... I'm working under the assumption you're using bitcoin core, but for other implementations, above statements might, or might not work.

But still, i don't quite get what you're asking... Did somebody sell you a wallet and told you that you could spend the funds funding 173bU1NZtrnxfXdVQFXsRp22nuc6fEmB4k and 1NFx9FETuduha8qJ6ehPYufTqVirB1Jf1D? I ask because this is a very, very, very common scam technique that's been used by scammers for a long time... They sell encrypted wallets that are either encrypted with such a strong password you'll never be able to brute-force it, or they sell a watch-only wallet containing no private keys at all, or they sell a wallet that has been modified so the private key in the (encrypted) wallet is just fake.
The endresult is the same tough: the victim is lured into paying a lot of money in return for a wallet they think contains a lot more money... But then they find out that this "lot more money" is simply unspendable or not there. In order to protect yourself from this scam, always remember: "if something seems to good to be true, it allmost always is". Nobody is selling a wallet worth $22.000.000 for $1000. That just wouldn't be a good business model, no matter how they try to sell it. I've seen many variants, like people claiming to sell wallets including payments for illegal items, so they sell "dirty" wallet for a fraction of their value: it's a scam... Those sellers  know about anonymous coins, they know about mixers, they know about coinjoin, they know about non-KYC exchanges, they're just feeding you lies to get you to pay money for a wallet whose funds you'll never be able to spend.
654  Bitcoin / Mining / Re: [b]is it possible to mine bitcoin on paper?[/b] on: August 19, 2021, 07:10:29 AM
Well... Yes, *theoretically* it *should* be possible to do this...
HOWEVER....

You'll need to take the header of the most recent valid block, manually create a new header (https://en.bitcoin.it/wiki/Block_hashing_algorithm), then you'll manually have to pick a nonce  within this header and calculate the header's sha256d hash on paper... The odds of picking a nonce that leads to a sha256d hash under the current target is astronomically small. But let's say you find one: to finish it off, you'll have to find a way to broadcast your block to the other nodes (nope, afaik, there is no "website" where you can submit blocks, you'll have to find a way to broadcast it to other nodes manually).

To top this all off, you'll have to do this BEFORE the rest of the network finds a new block and broadcasts it... As soon as they do, the  rest of the network will be using the new block's header to build their blocks on, and your block will be stale. So, you'll have to finish all these steps in an average time of 10 minutes... Maybe you're lucky and the rest of the network needs 15 minutes this time, but it might also be 2 or 3 minutes...

Now, i don't know how fast you are, but here's an article you could read: http://www.righto.com/2014/09/mining-bitcoin-with-pencil-and-paper.html
This guy hashes 0.67 hashes/day, so if he managed to pick the right nonce, there'd be no way he was on time for broadcasting his block...
655  Other / Beginners & Help / Re: Two wallets - same "defaultkey" on: August 19, 2021, 06:31:39 AM
@tranthidung: that's true, but the OP is talking about the defaultkey, which is an obsolete object in the wallet.dat but it should still be there and it should be unique (IIRC) unless a wallet.dat is copyd.
To be honest, i never gave to much attention to the defaultkey, it's been obsolete for a long time... So i actually had to look it up in the wiki initially Smiley (https://en.bitcoin.it/wiki/Wallet)
656  Other / Beginners & Help / Re: Two wallets - same "defaultkey" on: August 19, 2021, 06:02:32 AM
Yes and no,

If two wallets contain the same key, the can also be copy's from eachother. Copying the wallet.dat is technically possible, two different nodes can use the same wallet.dat at the same time, but each unspent output can only be spent once (so if you spend it from node 1, you can no longer spend it from node 2 that's using the same wallet.dat).

So, it's usually not a very good idear to use the same wallet.dat with different nodes, but technically nothing is stopping you, and there might be some edge cases where this is usefull.

On the other hand, if you have 2 wallets that are defenately not copys, and they contain the same key... yes, they're probably fakes.

Are you just learning about bitcoin, or do you ask this question because you're faced with some kind of situation?

I like the general idear of what you're doing... However, i did try to register, opened about 4 or 5 video's on my cellphone, watched 4 or 5 full adds before the videos and at least a dozen banners, let the videos play for a while... And didn't earn a single satoshi...
I didn't really expect to see more payout than, let's say, a BCH faucet, but 0 sats seems like lowballing  Grin

I also agree that LTC or ETH would be better alternatives than BCH... BCH isn't well liked by a lot of people in this community.

I already gave this user a negative tag for exactly the same issue as soon as i saw he was posting this crap on several subforums... Eventough his script is encoded (so really hard to read), it's pretty clear that the qr code was indeed a payment request designed to replace the payment request shown by the payment processor.
And even if it was a donation-button (which i seriously doubt), he would still be posting a way to defraud an honest company, which would still be enough to give a negative tag.

Thanks, I will try it later. I have used Kleopatra for asymmetric encryption, but I think it can only encrypt messages.


So you're using windows and have Kleopatra installed.
IIRC, you should be able to encrypt files with Kleopatra aswell, that being said it has been a long time since i used this tool, so i might be mistaking.

An other option would be to just install openssl. It's open source and the sourcecode can be downloaded here: https://www.openssl.org/source/
Or if you prefer a binary, so you don't have to compile it yourself, you can look over here: https://wiki.openssl.org/index.php/Binaries

But like i said previously, there are dozens of ways to solve your question...Some might be superior to others, some might be using unmaintained code, some might be ideal to use in scripts, some might have a nice gui, some might use only tools available in a standard windows distribution... Many roads lead to rome for this one Smiley

A thirth option just popped in my mind (i'm sure many more options will come up over the day): you could use 7zip and just create a password protected archive right away Smiley. I think similar tools offer a similar option (i know winrar used to include encryption in it's gui aswell, same for winzip... DYOR before using these features tough, check if there weren't any vulnerability's found in the encryption mechanism before using them)
