You guys
He says, while addressing a single person who happened to reference a post I made.
I'm really not familiar enough with all of Bitcoin's security features to make an argument for or against its effectiveness when dealing with a really devoted attacker, I just know that it lacks "inside guys" and that it would be rather inefficient to devote resources to counterfeiting it when it's far easier to scam people out of their wallets (or just counterfeit real money).
That's pretty much exactly it. Saying that Bitcoin's security isn't good enough because someone really determined could maybe get past it is like saying that the security of our nuclear arsenal isn't good enough security because someone really determined could steal it and get the launch codes inside.
If Bitcoin was easy to crack, it would have been done already. The amount of computing power needed to edit the block chain (which would purely allow you to add counterfeit money, rather than take anything), combined with the fact that your job gets harder every 10 minutes and the encryption is constantly fluctuating to keep the rate of bitcoin production the same, means that nobody would even bother. You'll have a much easier and more productive time trying to con people out of their bitcoins or hacking online depositories to steal them (which has happened before and is usually falsely reported as "Someone hacked Bitcoin!"). The only group likely to have the computing power to fuck with the block chain AND willing to engage in it, with all the risks of being caught, would be either a governmental entity or Lex Luthor.
