It is highly likely possible that the attacker might have got your backup phrase, he imported it into a different client and moved all the stored coins from there. That may be one of the reason for you not getting any activity log on your gmail account. Did you upload your backup phrase somewhere online ?

If your private key/backup phrase is hacked, there is no point in contacting the support team as they can't really help you.

Thank you for opinion Edwardard,

i didn't upload my backup phase online. i knew value of  backup phase. if i want to open my wallet i have to pass 6 password to reach my wallet.

i met many people and told my all stories but they sure that is that impossible to hack your system and transfer your coins without pass this security.

Google Authentication Key Generated on  Each minute.

I got all  Notification on my Registered Email ID & Mobile No. but i Didn't get any notification of This Transaction.

I rise Many ticket's too blockchain but they didnt give me valuable answer.

i think that Blockchain have all clients login information but they are not providing to customer.

please help me for more information because worth of 410 BTC.

again i request you Edwardard if any clue or information please tell me.

Just to make sure, you are talking about the service called Blockchain.info < https://blockchain.info/ > right?

We do not refer to this service as Blockchain, because people get confused between the technology Blockchain and the website/service Blockchain.info.

You have to remember that 2FA and online services like this are the most vulnerable targets in Bitcoin. If their code is exploited, it has nothing to do with the actual Blockchain technology.

Hackers target these services, because they cannot hack the Bitcoin protocol. These services are exploitable, because the developers code is not Open source and in many cases not checked by Peer review.

A person can never be certain that his computer wasn't compromised. It is entirely possible that you got hacked and that somebody just saw your backup phrase while you where checking it out yourself. Besides, google's security is far from no 1. No 1 would be if you had a paper wallet and if you really had hundreds of bitcoins, then I really don't understand why you didn't use a paper wallet for so much money. 2FA has been broken for years, by the way and trusting any service to keep you safe is unwise. You should have taken the security in your own hands, as these services make best targets for hacks due to their high value. You could go more in detail to figure out what exactly happened, to give you some closure, but if your coins are in another address, they are gone, no one can get them back other then the owner of that address.

All the 2FA and passwords in the world will not help you if the attackers have your 12 word b.info recovery phrase... those 12 words = all your private keys... and they're not password protected. Put it into https://iancoleman.github.io/bip39/ and "All your Bitcoin belong to us" Undecided

Who knows, maybe your info leaked during the HeartBleed thing... or despite your best efforts someone got some malware onto your PC...

410 BTC... that's like over 1.6million USD... and you were keeping them on b.info??!? Shocked Shocked Shocked  Lips sealed Undecided you couldn't spare ~0.03 for a hardware wallet? or use offline generated paper wallets?
