Some companies are already making money on the vulnerability of NEW credit cards, look at this -->
http://www.signal-vault.com/ ...Everyone is going on about Bitcoin hacks, but
people are losing Billions with credit card fraud. If that was not true... Why would companies like this exist? There is not a public telephone system in the world, that was not hacked
in some way or the other... people will hack it, because it's a challenge. So far Bitcoin is holding very good, and we have not seen major losses from direct hacks to the protocol.
There are simply too many eyes on it, because it's Open source and decentralized.
