It's unrelated to sending bitcoins.
You can sign a message with your address. So you can show that you own the private key of that address without revealing it
Why? To prove you own an address. Who can see the message? As i said, it's a feature unrelated to sending bitcoin, you sign the message and it give you the text, then it's up to you copy-pasting where you need to. It's totally free of course.
Changing the message? If you change it the signature no more verify the message.

@matonis So, MC and Visa do currency exchanges automatically? At quite a hefty charge, I'll bet.
How can they do chargebacks, though?
Mastercard never see bitcoin. The BitInstant guys receive your bitcoin, exchange them and put dollars/euros on the card. Then you can use it like any other debit card. |

Ok, maybe I'm missing something here. If the funds backing this card are bitcoin, does that mean bitpay will convert it into local currency (dollars, for instance) when it's used at a merchant that doesn't know anything about bitcoin? That doesn't sound plausible to me.
It's exactly that. You load the card with bitcoin and when you buy something it work like a normal debit card, the merchant receive dollars/euros/whatelse he is asking. BitInstant receive your bitcoin and exchange them for dollars/euros. Like BitPay. By the way, there's also a story circulating that MasterCard has denied that it will issue these cards.
Frankly, I can't see the major credit cards validating bitcoin because it's probably the biggest threat to their hegemony on payment since they were invented. That's true, BitInstant issue the cards, not mastercard |

Unfortunately I messed up by sending the paypal payment as a gift, at the scammer's request, so I won't be able to get it back. Gift payments can be happily chargebacked, that's why no one use paypal for selling bitcoins. |

I think fascism means what Italy had during and before second world war: a tiranny, a dictatorship, something that ruined the nation.

Bitcoins are just our little game, we have our software and we play with it with these things we created, bitcoins. How can it be real money? And have any value? That's impossible! |

Yes, but using Nvidia cards for that is retarded. ATI is much much much better. But well, if you want to use something simple like Amazon EC2 instead of setting up hundreds of rigs with ATI cards maybe it's fine.

Kim Dotcom. Good point Sad but true. Then again, I still gotta see if he actually gets prosecuted. I mean they arrested him all right, made a ridiculous show out of it, but now what? I don't know what happen to him, but it seems like he is preparing to launch another file sharing service. He's actually seeking for another payment processor. Maybe we can ask him to try Bitcoin.Already done  |

Fascism sucks. Are you really trying to justify it? It's dictatorship and tiranny, nothing more.

Under no circumstances could an attacker take anybody else's money. An attacker's capabilities are limited to taking back their own money that they very recently spent, and preventing other people's transactions from receiving confirmations. If the attacker make a blockchain starting from like a year ago he will have all the coins mined from a year ago until today so if you have coins that were mined six months ago, the attacker will have them. So yes, the attacker can take anybody else's money. |
