Has anyone heard of a hack or attempted hack on Bitcoin
there has been lots of hacks of web wallets, online wallets with no security measures, exchanges and things like that. but none of these are "hacking bitcoin" itself.
To the people who have lost a lot of money it really does not matter what the technical details are. It really does not matter. fact is they bought bitcoin - they got hacked - the money was lost. End of story.
Techno-types like you always end up blaiming the user for anything bad that happens so you can protect your precious ivory tower.
