Bitcoin Forum

Recently 2double0 (https://bitcointalk.org/index.php?action=profile;u=153776) opened a loan request thread (https://bitcointalk.org/index.php?topic=5102150.0;all) asking for what turned out to be a 0.05BTC loan (it looks like it might have originally been 0.06, but that is not really important).

I know based on blockchain evidence that 2double0 used to be owed by marcotheminer and believe he was for many years, however marco is/was also an account seller, so it is not out of the realm of possibility that it was sold.

What was strange is that marcotheminer was vouching (https://bitcointalk.org/index.php?topic=5102150.msg49435265#msg49435265) for him being "who he says he is" AND claiming to have given him a (apparently) no collateral loan from "a while ago (https://bitcointalk.org/index.php?topic=5102150.msg49434555#msg49434555)".

2double0 recently came back from a ~10 month hiatus, with his 1st post after returning made Jan 25, 2019 (a loan request (http://archive.is/9oaWY#selection-2073.1-2121.47) offering his account as collateral), and his last post before leaving was in March 2018 (wrapping up (http://archive.is/9oaWY#selection-2161.1-2199.44) a bounty campaign he was apparently running).

marco also recently came back from a hiatus, with his first post back being on Jan 16, 2019 (claiming a giveaway (http://archive.is/D4y84#selection-941.1-975.27)), however on Jan 22, he reopened his lending thread (https://bitcointalk.org/index.php?topic=750507.0) (that has subsequently been locked, apparently without making any additional loans), and the next day asking for a 1 ETH loan (https://bitcointalk.org/index.php?topic=5101258.msg49385005#msg49385005), which was the same day 2double0 requested his loan. Before he left, his last post was in October 2018 (asking to join a signature campaign (http://archive.is/D4y84#selection-1015.1-1115.27)), however this was only two posts, and prior to that he posted in May 2018, trying to sell a couple of domains, and prior to that was in June 2017.

Based on the above, I would say it is reasonable that marco and 2double0 are currently the same person, although I cannot rule out this not being the case. Perhaps someone can review the security log back to March 31, 2015 when marco confirmed to me that it was "in his possession".

It is obviously not proof of a scam that someone has multiple accounts or is involved in the account market "underworld". The vouch, strictly in regards to marco saying that 2double0 is "who he claims to be" might be something I can look past if they are the same person. The claiming to have given 2double0 is certainly not appropriate if they are the same person -- even though there is no claim of a successful repayment, it implies it is the opinion of a longstanding forum member with positive trust that someone can be trusted when no one else is saying as much -- if they are not the same person, it would mean marco sold this account, which would be somewhat of a conflict of interest to give this vouch.

I saw the above and was considering making a thread about this.  I certainly do not approve of vouching for yourself, or giving what may be a fake no-collateral loans, but was somewhat on the fence about opening this thread, mostly because I have no way to efficiently go though the old security logs to check for evidence that 2double0 changed hands. However.....

The most damming part of the loan to 2double0 is the blockchain activity immidiately prior to hacker1001101001 making the loan. 2double0 asked for the loan to be funded to 1J4YGjWGyWSQ1U8VCTUeXn3XqMxiUhheZ7 and hacker1001101001 funded the loan via txid 9e25bbb34f3c4504f3275c93502afe82efec15ecd04581b1d9f9f19dfc48aa6b (https://www.blockchain.com/btc/tx/9e25bbb34f3c4504f3275c93502afe82efec15ecd04581b1d9f9f19dfc48aa6b), whose inputs are from 1JAYESHqohMYvXS4Do6ZNEYJiwZ588MVKi -- this transaction was confirmed in block 564462, which also confirmed a withdrawal from huobi in the amount of 0.0502 (enough for the loan plus a small amount for the tx fee), but the strange thing is that 8 blocks prior to hacker1001101001 receiving the withdrawal from huobi, he received 0.00001 BTC from 1J4YGjWGyWSQ1U8VCTUeXn3XqMxiUhheZ7 the address 2double0 asked the loan to be funded to. This might be circumstantial evidence that hacker1001101001 may be the same person as 2double0.

PS - the loan thread was immidiately locked after receiving the loan, which is a practice that I very much dislike, despite its stated goal of eliminating useless posts by those with paid signatures.

As on his loan thread, I posted about it and that marcotheminer and 2double0 are the same people. Also, you know Marco opened a loan thread at the same time he was asked loan he locked his loan thread after several posts which we made and also from a private message. And 2double0 send a message to me which seems like account sells. He told me "if you can't give me 0.05 then no problem, how much you can give me by taking this account as collateral". I offered 0. Both people from different account tried to take the loan and sent a message on several ways, though I told not to send me any more message. So, there is a lot of chance that is running by the same people and also this loan will be a default. If it cant be default this time then there might have 2 reasons:
1. will try to take more loan then a scam and/or
2. To avoid loss of both accounts as we are discussing it.

To be entirely fair, marco was at one point entrusted with 50+BTC from a new (at the time) exchange (worth ~$25k at the time) to run their signature campaign.

He has somewhat of a history of these kinds of shady shenanigans, and I am not entirely sure what his end game was/is. It may be to earn more in (custom) signature deals, or otherwise earn money in the marketplace, or to eventually sell his accounts at a higher price with positive trust. Or it may be to build up trust, and give trust to his other accounts and then use those accounts to scam, preserving his trust. 

I actually asked 2double0 in PM about the loan details that he defaulted and which is now he is repaying by participating in signature campaigns(with proofs). I didn't got any reply and he also locked the thread after it was filled by hacker1001101001. I was going to create the thread myself but you saved me the work.

Anyway this is something interesting which I didn't noticed and I will look into it.

Aye. It makes no sense when one sends dust to an address (which 2double0 presumably does not know prior to hacker's tx) just moments before the loan is fulfilled.

Unless we see evidence of some kind of communication that justifies the 20 uBTC transaction, this seems like a case of a self-loan.

Okay, if it is self-loan then they are alt account and trying to scam. Because by self-loan they will try to be trustworthy and will fly away when someone will fund them. In this way, they can't be trusted and they are a genuine scammer, isn't it?

hacker1001101001 should have had 2double0 verify his signature publicly, in the thread, instead of just instantly filling the loan. it's also peculiar to me that both users just starting posting frequently in Meta around the same time.

I don't think they are a separate account. I think they are alt account and alt accounts usually don't verify the signature, don't give transaction id as they don't send coin but in this case, they sent to make it trustworthy and as there was discussing for not to fund by anyone.

Firstly Yes I provided a loan to 2double0 (https://bitcointalk.org/index.php?action=profile;u=153776) after looking at his post in the lending section here (https://bitcointalk.org/index.php?topic=5102150.0)


I would like to clarify what Quickseller said here :


The transaction you are talking about which occurred here (https://www.blockchain.com/btc/tx/0881498648d03ac7a2fca6dc23f154dee9c345420267bf6b7051c6c7be214255) is the one which I asked 2Double0 to confirm his BTC address by sending me a small amount of BTC to my BTC address. I did this as he said that he holds the address 1J4YGjWGyWSQ1U8VCTUeXn3XqMxiUhheZ7 in his blockchain.com wallet from where he was unable to sign a message. He also sent me some ScreenShots of him logged in with the wallet in his PC.

Form this I confirmed that he was owning an address posted from his account at least 1.5 years ago here (https://bitcointalk.org/index.php?topic=1082477.msg24340538#msg24340538) and I sent the loan directly to his previous address.

Thank You nutildah (https://bitcointalk.org/index.php?action=profile;u=317618) for notifying me about this thread

I agree that I also have been unable to sign message from address which I hold in my blockchain wallet. Do you mind sharing screenshots of your conversation with 2double0 publicly or maybe share with someone trusted (i.e actmyname if he doesn't minds)?

Why not you bro? You too are a very trusted member of the community as per I see.

I can share the screenshots of the telegram conversation with you via PM. Let me know if you are willing to verify it.

hacker1001101001 sent me the chat screenshots and it checks out with he said in his previous post. He also sent me screenshot which verified the 2double00's telegram id. Hope this rules out the 2double00-hacker1001101001 part unless anyone have more questions to ask.

Feel free to PM me for screenshots (but will check out with hacker if he is comfortable with it or not).

Thank you for confirming and helping me to verify. I hope your confirmation would be trusted by most of the people here.

If it was discussion via Telegram, surely you can forward the messages so that an outside source can ensure the screenshots weren't doctored?

Yes, I can forward some messages confirming I chatted with 2double0 only.

@Avirunes please let me know your telegram ID, so that I could forward you the message and you could confirm it with my screenshots.

He forwarded me those and this checks out as well. It's all legit.

Going forward I recommend to you conducting all forum member loan-associated business on the forum. As you might have figured out by now, it would have been much more transparent had you performed the address verification bit in the loan thread where it was available for public inspection.

Yes, I too prefer dealing here on the forum itself to keep the deals public and open to all if any problem occurs later. But in this case both of us wanted to exchange some images to confirm the address which was pretty easy to deal with on telegram than through forum. So I preferred contacting him on telegram and later confirmed it on the forum.

But I will try to keep all the trade related conversations on the forum in the future. Thank you for your advice by the way.

He was asking to have the loan sent to the same address he posted 1.5 years ago. I don't think I understand the logic in asking for a test transaction out of the address you are sending the loan to. Also, as an FYI, it is possible to sign a message from an address in a blockchain.infocom wallet -- you would need to export the private key, or xprivkey via the console then import it into a wallet that can sign messages, or at least this was the case in the past.

I was also informed that 2double0 changed his password one time in May 2015, within one day of when marco changed his password. I don't think this is an indication that either account was sold, and think it is more likely marco was changing all/many of his passwords.

Just to let you know the logic:

The OP first had a different BTC address where 2double0 wanted the loan to be funded, which was bc1ql4gn6r75sydqwe99qz6nc44mvkzcfc4hqwqn3y posted by him here (https://bitcointalk.org/index.php?topic=5102150.msg49890923#msg49890923).

So, I asked the test transaction form the Old BTC address as he needed the loan to be funded to a new one. But later he said he can accept the loan on the old one too so sent it there by confirming the address once.

But later the OP of the thread was edited by 2double0 with the old BTC address confirming his access to it by sending me a small amount of BTC.

I know that and have a more better and easy method than this to get private keys from blockcahin.com. You just need to set a PassPhrase to your wallet on the blockcahin.com. Put you're pass phrase on BIP 39 Mnemonic Code (https://iancoleman.io/bip39/) and you will easily get private keys to all the BTC address linked with your blockcahin.com wallet and later you can sign a message with the Private Keys for sure. Hope this helps you. ;)

But 2double0 just sent me some minimal BTC from the Old address which made the deal quick.

It looks like 2double0 is going to be late repaying the loan, after allegedly obtaining an extension from the lender.

Oh, and at least 2double0 ^allegedly^ managed to repay his lender.

I just can't stop laughing my ass off watching a thief trying to expose a policeman  :D
Look, who's trying to stop me. Quickseller, one of the biggest account selling machines here on this forum who made money especially through trading and trafficking his own accounts and accusing and derailing many good people out of the forum through his skills shills. You have been deliberately trying to expose me and Marco and saying that we both are same personalities, but hey fucker, do you even see that there's a big difference in both of our language here? Look at his words and English, then look at mine and tell me whether I'm him or not. It is true (and I'd give all the blame to destiny here) that we both came online almost the same time. And I'm also not denying the fact that I had been in his contact, so this is another thing which proves that we are not the same people. I think I am just colliding my head on a rock here.

I confirm that 2double0 (https://bitcointalk.org/index.php?action=profile;u=153776) has smoothly repaid my loan as per he said. And I have no doubt about his trustworthiness there.

---

I also think that the above accusation against 2double0 (https://bitcointalk.org/index.php?action=profile;u=153776) is bit of an over exaggerated and there is not much happening here. I have successfully provided the proofs of the transaction and I think the thread should be locked with the title getting edited.

No. there is blockchain evidence that your account was at least at one point owed by Marco. There is a password change (one) that makes it possible that you purchased the account from him.

I don’t subscribe to using “personality” to link two people together.

You people waste too much time..

Does it really matter who provides the evidence? To me the important part is if the evidence is valid. If quickseller was offering me a deal, his trust would make me think twice, but he's not, so his reputation doesn't matter at this particular time.



Challenge accepted.


Your language wasn't that much different a couple years back. To be honest, you were both shitposting a lot.





You also both liked ponzis.  ::)




You both took part in the same giveaways right next to each other. Coincidence?

Maybe, but then it happens again a week later.
http://archive.li/t79ct


There's also one particular thing you both liked to do and this is putting an exclamation mark (or double) after the first word or phrase in a sentence.
Examples:

This is excellent research and at the very least it proves both are terrific douchebags. If I had any merits I would send you one.


Its weird because:

1. The loan itself was weird.

Quote: (https://bitcointalk.org/index.php?topic=5102150.msg49418354#msg49418354)

So what kind of health issue is this??

2. You handled the loan details off-forum, in a weird manner. Even if you are naive and didn't know any better, it raises suspicion.

All is in the past, but hacker, you should slow your roll a little bit. You went from shitposting bounty hunter to lender to forum issues expert too quickly.

I don't think so. I still have some doubts and I am also sure others have theirs as well.


2double0 at some point was in possession of marcotheminer earlier. So up there^^ you might have found some similarities when Marco actually owned that account.

That was my intent after seeing this post:


It's possible to find more proof than said transaction that their accounts were controlled by the same person.

There's also the argument 2double0 that their language is different. IMO, it was still undergoing similar changes in 2016 and significantly improving.

Over the years marco went from posting like this:


To this:


So, I'm sure he would be perfectly capable of producing posts of 2double0. Unfortunately, we can't compare. After 2015, his activity decreased from 10 post per day to 10 posts a month in 2016, and 5 (mostly short) posts per month in 2017. It gives the impression that it all went downhill from when he got his first red (2015). Switching to a new main account and working on improving the language there would seem like a good idea, don't you think?

To be clear, I'm not saying the accounts are still owned by the same person. I just haven't seen a single proof that they aren't throughout the thread, and explanations like "we aren't the same, compare our posts!" are poor and questionable.


Are, or at least were. Marco used to bump ponzi threads, farm giveaways with his alts, shitpost to level up accounts and trade them in 2013/14. You can expect a lot of questionable future activity from someone like him.

Yes, the reason for sure looked weird, thats why I confirmed if the account is owned by the original owner or not. He atleast had his account at risk if he did not paid my loan back. But I am gald it didn't happen and the deal was smooth.

---

Thank You for your apprication but I don't understand what it's meant by "slowing the roll little bit". I think you are a bit over suspicious about me.

Yes, I handled some of the conversation off-forum (on Telegram) but there was nothing intentional behind it. I just found it more easy and fast to converaste there.

Although I just confirmed that he holded the address linked with the account some years back on telegram and confirmed it here (https://bitcointalk.org/index.php?topic=5102150.msg49897630#msg49897630) to fund the loan. I don't think just getting the conversation off-forum would make it suspicious.
