Bitcoin transactions are irreversible, so you can't get them back


But if you know HOW it happened you can prevent a future occurrence.

How do you usually access your wallet? Do you use the website on a PC? Or a mobile app?
Were you given a seed phrase (a set of 12 or so words)? How did you store the seed?
If you're using a PC then you should do a full scan of it for malware.

It's blockchain.info, it's non-seeded so he doesn't have the 12 words.

If your funds actually exited your wallet there is nothing you can do, I assume that there is nothing to do with blockchain.info operators and it's probably your wallet/computer has been compromised.
It's a lesson to learn- next time if you store funds that you can't afford losing then do it on a hardware wallet offline, so you won't risk losing your funds due to lack of security.

Blockchain.info has the 12 word seed. The user owns the private keys and the seed. I think it's a good wallet, considering it's a online wallet....
Probably someone got access to his seed. As he uses 2FA, it's very unlikely the site had been hacked.

I asked a few times but he didn't answer how he stored his seed...

That's not very convincing. If you said it's more convenient in certain ways, then that would be more understandable, but aside from convenience, which in today's world is very questionable with how many solid alternatives there are available in client form, there is nothing that these sites offer as additional benefit. Seriously, why should anyone here use an external site or service while we can skip them entirely, and that *almost* without missing the convenience they may offer? Back in the days there weren't all that many alternatives available, so people kept using online wallets, but in current times that's no longer needed with how many options we have right now. It's just a matter of logical thinking....

That's because of people like you, I have formed the view that online wallet blockchain.info it is safe and convenient. Therefore, a hardware wallet was purchased and lying on a shelf in the closet, and I used the service blockchain.info. You all know the result... Stolen coins.

I long time could not find the seed. I wrote about it in this tread. Now found, the seed was stored in several photos on my iPhone 7 (iOS 10.3, no JB, I not used iCloud and other cloud services, TouchID enabled, backup copy of my phone I don't do).

Now you are blaming me for your mistakes. You first started to blame blockchain.info, now that it is clearly not their fault, you are blaming me for your disregard of basic security rules.

That's the wrong way to store your seed. That's how the hacker got access to it and stole your coins.

Even if you had a hardware wallet you would have been hacked.
Even if you had a paper wallet you would have been hacked.
Even if you had a bitcoin core wallet on an airgapped pc you would have been hacked.

That was not blockchain.info fault, as it is the most popular wallet out there.When you click on the Seed on blockchain.info they tell many times to write it on paper.

Learn from the experience, store your hardware wallet seed on a piece of paper or an offline environment.

No, no, no))
I mean, you can't trust online wallets. And certainly not to tell anyone else what allegedly is a safe way to store coins.
Confirmation? Today, right now - MyEtherWallet service reports that their DNS servers were hacked and entering the service site passed the transition to the phishing site. Already a lot of messages about the theft of funds from accounts. Then you say that online shit like blockchain.info is it reliable? Difference blockchain.info and MyEtherWallet is huge, from MyEtherWallet there is feedback, they recognize problems and respond to messages, not write - it's your problems, read the agreement...

I agree that it wasn't right to keep seed that way and now I'm using a different way, but I don't think anyone had or has access to these photos.
Tell me exactly how you can access them? Has anyone done this yet?

I am not a hacker and I don't know anything about Apple products.

But there are a few weak points on your iPhone:

-Apple has synchronization stuff.
-Your personal phone is online100% of the time and your seed was not even encrypted.
-You may have been exposed to phishing sites on WhatsApp/telegram groups, emails (I know that's unlikely,but your personal phone is more exposed to that than other devices).

Storing seed on a piece of paper is 100% anti hack, unless he has physical access to the paper.

Think like this.

Every time you write your seed (or scan photo etc) on a device with internet connection it is considered exposed and you should transfer your funds immediately. Your seed was online 100% of the time (not matter that it was locally on device, because the device was online).

It's very sad what happened to you. I would be devastated. But don't let this move you away from this technology. Use this opportunity to learn. You will make that money again.

You can try but I think you will not get them here...
You can mine those btc again. nd store them on multiple wallets. I think this is the best option.

Yes, storing on multiple wallets is not a bad idea.

1) I have a hardware wallet but I didn't carry any coins on it since I thought the service was blockchain.info safe
2) What is the problem to write on the main page blockchain.info - WE are NOT RESPONSIBLE for anything
3) I asked to help me get the coins back or to understand why they were stolen, and not to write tips on what to do with education.

Stolen bitcoins from blockchain.info. Account totally clean 0.00 left. Lost everything a lot of $$$$$$$$$. Guy from support team just said sorry and that all. same answer like guy above.I don't know what to do.

We believe we are blockchain's.com victims - as for now we are the group who lost ~400 BTC in total and every one of us was using paper wallets paired with blockchain.com‘s app or website.
Please check out our video on youtube (English, German, Chinese) to get more information:
https://www.youtube.com/channel/UCbJi2VKiXy8VIERjea_KSEw .

At the beginning of July, we will be in Luxemburg to issue a case in Luxemburg's prosecutor. Lastly, we'd like to open class action in Luxembourg Court and sue Blockchain Luxemburg (blockchain.info) for security vulnerability of their software/API or stealing people's coins. It will only be possible with many pieces of evidence about Blockchain‘s software security issues or steals.

Could you please send us an email with answer our questions according to your case of losing your bitcoins:
- Has you your only been used with blockchain.com ?
- What kind of wallet was it?
e.g. (paper - with or without passphrase/hardware/generated by blockchain.info/etc.)
- Are you 100% sure your passphrase / private key were stored securely all the time and no one (not even closest friends&family) didn't have access to it?
- Could you provide us with a link to the transaction which is related to your case?
- Do you still have access to your wallet on blockchain.com?
- Do you still have your wallet address, private key and passphrase?
- How did your case end? Do you know any predictions of the real cause of your loss? (is it different than the actual status of your case?)

We will do everything to protect your privacy, but there is a possibility we would have to provide your contact details to Luxembourg's prosecutors. Do you agree with that?

Please contact us via email:
* English: thiefchain@tuta.io
* Chinese: thiefchain@keemail.me
* Deutsh: thiefchain@tutanota.de
