Is it possible for someone to hack my account? I mean, If I posted my address.. Can it be hacked?

Just from posting your address without private key? No.

Can be done but you will be but a memory by then as it will takes thousands if not trillions of years to do so. The 'hacker' would have to try every possible combination (private key) possible until he finds the one matching your public key. It would be far easier to hack your PC than it would be to hack/crack your private key.

Make sure your PC and wallet is secure and read up on this forum about paper wallets and other security suggestions.

How about when my laptop was borrowed by someone knowledgeable about bitcoin?

Did you have passphase set on your wallet? Did they know it?

Ive posted my add many times in some forums and chats. Now my remaining btc was gone. I still dont know why.

More detail and some screenshots will be helpful for further analysis.

just give me your address, I would hack your wallet only if If I am very, very good luck

You probably have keylogger in your computer. Nobody can steal your coins with only having your address.

Your wallet can not be hacked just by them having your address, they also need you pass key as well so unless you have mistakenly given that out I do not see how they could have hacked your wallet unless you have something in your computer like a keylogger in which case it's possible.

Only from the address, the chance to hack your wallet is 1,000,000,000 smaller than winning at the lottery.
To brute force attack it, there is no such computing power yet.


If you gave your computer, you may have had the wallet files there (maybe even without password!), maybe old copies which were there (or undeleted?).
Or, maybe you got a pretty keylogger (from a website or from a friend that borrowed your computer) and then it's all simple!

Posting a public address wont get hacked. there are only three ways to get hacked
1) your public/private key are provided to you through a third party service like blockchain.info or other webwallet. and that you had a key logger on your computer for them to get to your online wallet service
2) partly to do with point 1. you downloaded a coin related program that had a trojan in it to either steal the bitcoin wallet.dat file on your computer or it's a keyboard logger that reads your log-in attempts
3) you let someone into our computer either remotely through teamspeak or in your house while you were not looking.

the majority of the time its point 2 that is to blame. and it usually is a program you installed within just a couple weeks from when you got hacked. so please reply with any/all crypto currency programs you installed within 2 weeks before you got hacked.
i an betting 50% you downloaded a supposed 'bitcoin generator' program from a youtube video promising lots of free coins and betting 25% it from an altcoin client, or 25% from a dodgy 'mining' tool.

please list any/all coin related programs you downloaded in the last two weeks as other people that get hacked, if they too list theirs we can all see a common pattern and find the culprit

Your money cannot be taken by someone knowing your public address or bitcoin would be utterly broken if that was true. Your coins are gone because you were hacked in some way and probably have some sort of malware installed. What wallet client were you using and what was the address the money was sent to?

With the pubblic address no one will ever steal your coins, just be sure to keep your private address safe.

If I did not logged out in my wallet. Is it possible that someone might transferred my balance i their wallet? and if yes, could I trace it?

You can trace where it goes on the blockchain, but it will be impossible if they use a mixer or an exchange etc. Somebody could send the coins from your own computer, so make sure it's password protected. Also, different clients will be different so I can't speak for all of them.

Not if you have set up 2FA (for web wallets) or if no one know your password (for personal wallets).

If so they can just run the bitcoin-qt wallet and they can do what they want with it, if theres no password on your wallet.

You can ask your friend to see your few last transactions.

I have posted my address to various sites/forums too and so far it is not hacked yet. :p
Maybe because it only has very little amount not enough to make the hacker interested on it. :P

Should thread closed??

Don't worry about it, the chance of having a collision is extremely extremely low.
And no, it has nothing to do with your low address balance.

You can find 3 addresses with over 130,000 btc on each of it, and those bitcoin are safe. https://btc.blockr.io/trivia/address ;D

My rule is do not post your address. You can PM your address so that you can trace back who knows your address. Posting will not.

I dont think address has anything to do with hacker, they need your wallet file..

Yes , (the hacker/person) need your wallet.dat file or he has imported your personal private key in a different method .

not possible.

same events as me, although no one else can access my laptop. I may install something terledor contained within the keylogger. it could be. very strange because suddenly my wallet for 2 years when the hack back into safe safe

If you haven't re-used that password on other site, the account hack is most possibly related to keylogger or phishing link.
BTW, you should enable 2FA to improve the safety of your bitcoin on the blockchain.info wallet.

Wow, over 130,000 btc. I wish I even have the 130. :P

It is possible to have your account (bitcointalk, blockchain.info, coinbase, etc) hacked.
It could be related to phishing link or malware on your computer, but it has nothing to do with posting your address at all.

yes your wallet can get hacked.

Based on your address no. If you have spyware, trojan, virus or keylogger on your pc then that's another case.

its pretty hard, but the possibility is very small.

No it isn't possible by just releasing public wallet, but if it has lots of funds and they now know who owns it, its a larger target and increases the chances.

+2 thread should be already closed.

Can it be hacked if I post my address in this forum?

I do not think it will hit if you just post the address only
