if I disconnect my pc will my BTC be safe

[Muhammed Zakir]

Don't compare Blockchain.info. Bitcoins lost through Blockchain.info is very big and no, many of them were *not* due to users' faults.

if you are referring to the reusing of the "R values" by blockchain.info . i have to say, it could be easily avoided if the simple rule of "always use every address once" was followed, it could have been prevented.

Reusing addresses are alright except it compromises privacy. Reused 'R values' were exposed due to Blockchain.info wallet's bug, not user's fault.

I think no
but someone can physically take your bitcoins either taking you wallet.dat file, or exporting private keys or other way

or your bitcoin keys already being leaked from the last time you connected to the internet, it would be safer if the PC was never connected to the internet.

at some point you have to connect your pc to the internet, whether you want it or not. just make sure before you do anything, your pc is clean and safe. then you don't have to worry.

I put my bitcoin on my mobile and I don't really connect on the internet much using my mobile. So I think it is secure. Plus, I don't let other people touch my mobile and I don't carry it much on the public. I only open it once I have an incoming payment just to check. This phone is an option phone. My wife and I share the same phone for contacts and she got this non-android mobile she uses as it lasts for a day or two.

that is what i said, it was blockchain.info fault and it was unforgivable.
all i am saying is, everywhere you look it is recommend that you should use every address just once, and this simple act could have prevented their losses.

It's been connected to the internet, if I turn the internet off, is there a way my BTC can be stolen without physically taking my pc?

you must back up private key before you shutdown
you can back up on Hardisk external or Flashdisk
cause we not know after shutdown PC we can turn on it, or some one steal your PC

depends on where u are storing your btc, if its on a pc - wallet , it will be safe as long as u reconnect ur pc,

I think you meant "safe as long as u don't reconnect ur pc". It can be safe even if he connects internet as long as he knows how to secure his computer from malware.

otherwise I Suggest u use an online wallet to store your cash and email encrypt it for extra protection! now days can even get mobile verification

Storing Bitcoins on an online wallet is worse than storing it in a local wallet.

it depends on whether the security of the site is secure enough and the procedures implemented so that they don't know your private key, either partially or fully. Example, greenaddress.it. They require at least 2 signatures and they cant steal it by using the only private key they have.

The backup part is kind of mandatory for everyone, regardless of the uptime. Stealing your PC is also easy if its turned on, main part is securing your private key. The only concern is that SSD have the potential to lose data if they are of the poor grade or stored at high temperature after a long time.

according to me there are 2 ways a person can steal your bitcoins
1) having acces to your computer while you are connected to internet
2) physically accessing your computer to do a theft
a person can also steal your data if you have stored it in cloud service.
