That's not how Bitcoin works.
You sign your transaction on your computer. Then you send the signed transaction over the network. Anyone can view that signed transaction and they would not have your private key.

Yes, private keys from transactions can not be captured. But there are other cases where a private key is exposed. I also don't mean you can get any private key but many. |

Having your private key exposed on a network connected computer is vulnerable to anyone. Not just governments or ISPs. I would be more worried about a hacker if my private key is not behind encryption or in cold storage. |

Please read a little bit into the topic before you make such suggestions.
The whole point of private/public key pairs, is that you don't send private keys.

This usually happens locally on your browser except if you are creating your private keys through a malicious web page... You have to worry about the code the web page is serving you and not about your isp... |

It wouldn't be as easy as you think. Read more on how it all actually happens.

To OP: Private keys should only be stored locally, on your own computer, encrypted. They should never be send over any network and Bitcoin does not send private keys when broadcasting a transaction. |

As long as the So called bitcoin community stays united, it will never fail. But if and only if, bitcoin was just a government project from the beginning, then i'm not sure what will happen.

This. /thread. Agreed. Why do so many threads start with a bold assertion in the title, then the text is a question about the correctness of the title? |

- observe internet traffic
- look for 51 character strings starting with 5 *
- collect them
- import keys and transfer all coins to own account

Why on Earth didn't you ask this first in Bitcoin Forum > Other > Beginners & Help so you don't look so stupid? And your title isn't even phrased as a question! |

To OP: Private keys should only be stored locally, on your own computer, encrypted. They should never be send over any network and Bitcoin does not send private keys when broadcasting a transaction. There are a number of websites that will allow you to generate a new bitcoin address locally, on your computer (to be more specific, on your browser). I would argue that it would appear, to someone with little technical understanding of bitcoin, that the UI makes it look like that the private key is generated by the website and then sent to the user. |

That's really can't be the way but what they can do is block some ports but again protocol can hop to another channels easily.
I can't see any easier blackhat way to crash it.

ow would this 'crash' bitcoin. If anything it would just increase the number of thefts. But highly doubtful.

Your private key should never be exposed to the internet, as this is a sure way to have your money stolen from you. If there is no way around transmitting your private key over the internet, you should only do so when it is in encrypted format, however even this is a very bad practice. |
