Re: Bitcoin Wallet Vulnerability

If you have lots of coins in your online bitcoin wallet,will posting that address in public like forums,facebook etc make it more vulnerable to hacking?
1.Should such addresses be kept secret as much as possible to keep them away from hackers eye?
2.If kept secret,is there a way for others to know how many wallet addresses holds big amount if bitcoins?

If you have lots of coins in your online bitcoin wallet,will posting that address in public like forums,facebook etc make it more vulnerable to hacking?: Yes, just as posting pictures of a stack of gold or a box of diamonds will increase your odds of getting robbed. You are essentially making yourself a target. Someone could want to hack you now who previously wouldn't have known.

1.It depends on your privacy and storage techniques but usually YES

2.They will still be on the blockchain so technically yes.

Nice, okay. Could you please explain how posting a public key would increase its vulnerability? - have you got an unknown method of spawning a private key from a public key?

It depends on your definition of vulnerable, will his machine be more likely to have hacking attempts ? It is definitely a possibility or even the chances of it physically being taken.

Does the public address give any information of the private key? Nope

I see it like this, X user decides to flaunt his public address and show off 100 btc, 2 months go by he forgets a friend of his chats him on FB tells him to download a game or chat program, X does it because he knows this guy he went to highschool with him a 10 years back. The file is infected with some tools and X user gets hacked and loses his btc.

Such an improbable way to make a point. The answer is no. I'm sure the OP said online wallet, even if it was a local wallet, what's to say it's not encrypted with sha256 and AES, are you going to tell me that both of those standards are also vulnerable?

Keylogger watches the pc and time before btc address or amounts entered, gets the password and uses other hacking tools pretty standard thing.
