I have been trying to get my head around this.. but I am not sure....
Say I have a password on my wallet as i assume everyone does... I need to enter that password whenever I send a payment, so thats all pretty standard..
Now say someone gets my wallet.dat I imagine they also need to know the password otherwise its useless to them right ? Ive read a few things about how people have been hacked/lost there wallet.dat, but I dont understand what the hacker can do with your wallet.dat if they dont have your password ??
Perhaps I am not understanding some vital concept of how the hole system works
