I'm very interested on the heuristic that you've used or referenced to point it to Coinbase.

They sent funds to the address 19kwMfNYTXnEAQ5MBDUL3rwhmwz8PKBU1t and then those funds were used to make a large payment where the change went to an address identified as belonging to Coinbase.

Thanks!
Interesting... so it's based on the tag by Arkhamintelligence with either its heuristics or by someone who used "Edit Entity+" button on the address' page.
Honestly, I'm not 100% convinced by the label, but that's a start.

What does it mean?

Suppose you deposit some BTC in exchange Z using the deposit address ABC. When you withdraw, your BTCs won't necessarily be coming from the same address. Instead, from one of exchange Z's hot wallets.

I'm not sure if it's the same in 2014, but typically, exchanges also consolidate deposits shortly after-- they transfer users deposits to another address of theirs shortly.

BTW, what about your old email account/s, op?

Somehow the 1JvooVJkuEe9bA1grCve2o5DRzkCv2gAB6 address seems to be linked to Coinbase, maybe you forgot you moved the funds ?

Please provide the specific details or links, thanks!

By the way, the original payment from Paymium was probably sent to a Cryptsy address if we look at where the change of this transaction went to.

According to this article, Cryptsy was using Coinbase to launder funds.

@slyyls if you remember having a Cryptsy account and ended up losing those funds when they disappeared, you might have been entitled to compensation from Coinbase. The deadline to submit a claim has long passed so unfortunately you might not have any options for recovering those funds.

Walletexplorer doesn't seem to be returning anything, so it's difficult to say whether the address belongs to another exchange or someone managed to access your account and withdraw the funds.

I'm not familiar with the exchange, but is 2FA mandatory? was it on 2014?

Thank you for your help.

I think there was Google Authenticator at that time.

How do you know it is Coinbase?

Quote from: Pmalek on October 24, 2024, 08:20:50 AM

More than 10 years have passed since those transactions happened. It's possible that you forgot about it and can't remember what you did or where you moved your coins. Do you still have access to your Paymium account? If you log in and check your trading and withdrawal activity, do the records match to what Paymium's support agent told you? Besides Paymium, what other services and wallets did you use at the time? That's where I would look in search for the missing funds.

In Paymium, it says: Transaction to an external wallet the same day of the purchase.

But it can be an internal job. There were suspicion about Paymium CTO @davout (ex Bitcoin-Central) at that time. You can read some posts about it here in this forum.

I bought Bitcoin on May 23, 2014, via Paymium at 20:11:30, and it was delivered to this wallet: 19CEZVuiARGq2n1f9rx7ndejgw4RpF8gaY.

However, it seems that the BTC was transferred the same day (May 23, 2014) at 21:22:00 to another wallet: 1JvooVJkuEe9bA1grCve2o5DRzkCv2gAB6.

I noticed paymium support has mentioned your withdrawal request was processed and transferred on May 25th? a mistake? Also, if it's s a custodial exchange, the withdrawal could come from another address then-- not 19CEZ

I hope you still have your old email accounts because you might be able to find hints that way. Try to search every possible keyword you could think of. You may be able to find account/s from other platforms for instance.

I guess May 25th is a mistake, not sure why they mentioned that date. They say that the Transaction was taken into account 2 days after the request. But it is not true.

Can you explain that part "if it's s a custodial exchange, the withdrawal could come from another address then-- not 19CEZ"?

What does it mean?

It seems like a centralized platform and why are you investigating a TX made in 2014 now? I mean, why exactly 10 years later? I am not targeting the platform but you did mistake by keeping funds in such a platform where they can access your funds for you as they said the tx was made on behalf of your request maybe they get it wrong or they did it on purpose what can you investigate now by just seeing it on explorers.

Who knows whether he was sick during that period? Ten years is actually more than enough for someone to lose track of some things especially if they had encountered difficult situations within that period. Moreover, 0.2 BTC in 2014 could worth more or less than $50 which is not a huge amount though, considering the inflation rate as at then, it's still a reasonable amount. The only mistake Op made was leaving his funds in such platform for as long as this.

It's surprising the transaction occurred within an interval of a day and Op didn't notice it either through mail or manual checking of wallet until lately. Even if you have intention of holding for a long time like this, you ought to have been checking it time to time to confirm if everything is intact. Judging from paymium response, I don't think Op stand a chance to retrieve that funds again.

I can see you've made a couple of replies in your local.board about this, I'll advice you be careful with any PM you receive or send out as scammers can try to take advantage of your situation and get some money from you.

You should check your email logs to detect any breach into your account at that time or any transaction initiated which you do not recognize. I can't find much scam accusations against this platform, which reduces the chances of this being an inside job from the exchange (doesn't eliminate it), making a hack more probable.

In big company like that, only the higher-ups have access to their hot wallet's private keys.

IMO, it's more reasonable to think that your account, device or PC was compromised and the culprit requested the withdrawal with it.
Anyways, only once you strengthen your suspicion (e.g. after an intensive investigation), contact the local authority where they are registered.
(but don't expect it to be easy and cheap)

Bitcoin Bottom was at $15.4k

As others have said, it's been like 10 years and you worrying about this transaction now in 2024 seems odd. I mean the chances of your account being stolen is more as there were no security measures back then or maybe the exchange which you are mentioning or the wallet which you sent your money to got hacked in these years? If it's not showing up for you, it's gone. Good Luck for the next time.

Have you checked your email box? The one related to your Paymium account. All exchanges send emails when withdrawals or requests for it are made. And if you find emails related to withdrawals from Paymium, then you should have received one mail from them for this withdrawal, normally.
Maybe you can also ask to blockchain monitor companies like Chainalsys or Elliptic (or any other of their competitors), they can maybe confirm if the address belongs to Paymium or not, for a small fee. I have absolutely no idea of their prices tbh.

Payment Gateway Allows Recurring Payments

I think if the money really belongs to you, then hire an expert to investigate the case, but one thing is for sure that money is now long gone feel bad for that. Or maybe you actually made a request and moved the funds to somewhere else like a exchange account as other mentioned.

I looked a little further.

1JvooVJkuEe9bA1grCve2o5DRzkCv2gAB6 sent to funds to 19kwMfNYTXnEAQ5MBDUL3rwhmwz8PKBU1t
https://www.blockchain.com/explorer/addresses/BTC/19kwMfNYTXnEAQ5MBDUL3rwhmwz8PKBU1t

ANd this a huge wallet. Probably an exchange, bulleteyedk mentioned it to be a Coinbase address.

I think back then, 2FA wasn't mandatory yet. But I really hope email verification for Bitcoin withdrawals was in place. If OP can verify whether they received any withdrawal email at that time, it might help. If there wasn’t an email, then OP has grounds to contest it, especially since I believe the exchange is licensed.

Hi everyone,

I'm trying to understand a transaction from back in 2014 and could really use some help.

I bought Bitcoin on May 23, 2014, via Paymium at 20:11:30, and it was delivered to this wallet: 19CEZVuiARGq2n1f9rx7ndejgw4RpF8gaY.

However, it seems that the BTC was transferred the same day (May 23, 2014) at 21:22:00 to another wallet: 1JvooVJkuEe9bA1grCve2o5DRzkCv2gAB6.

Here is the transaction on the blockchain:
https://www.blockchain.com/explorer/addresses/BTC/19CEZVuiARGq2n1f9rx7ndejgw4RpF8gaY

Is there a way to find out if this address (1JvooVJkuEe9bA1grCve2o5DRzkCv2gAB6) belongs to a platform like Paymium or any other exchange?

Could it be possible that the transfer was initiated by a Paymium employee to one of their wallets?

There are three transactions that day to this wallet, which makes me think it isn't one of my wallets, as I didn’t have any other BTC at the time. I don’t remember transferring those coins.

I reached out to Paymium support, and this was their response:

Paymium Support Message:

Quote

"You did indeed purchase 0.2551671 BTC on Paymium on May 23, 2014. You then requested a transfer of these BTC on May 23, 2014, which was processed on May 25, 2014.

You can find the details on the blockchain by following this link:
https://blockchair.com/bitcoin/address/19CEZVuiARGq2n1f9rx7ndejgw4RpF8gaY?from=paymium.

You did not sell these BTC. They were transferred on May 25, 2014. You can see this in your history.

The purchase and transfer of the BTC were indeed actions initiated by you.

The balance of your Paymium account is consistent with your past transactions."

Any insights or suggestions on how to investigate this further would be greatly appreciated. Thanks in advance!
