Lots of articles claim the BTC to be hacked and insecure but is the dollar insecure for similar reasons. Someone hacked mt.gox so bitcoin is insecure?? That means the dollars insecure, because robberies happen on exchanges around the world all the time. If an online wallet is hacked it's your own fault for trusting the wallet, bitcoin is not insecure, the people you trusted your money with are. So my conclusion is, if bitcoin is deemed unsecure then you are also deeming the dollar to be a high risk currency.
And, the latest news. The selfish miner hack. The problem is, it requires some amount of power to get a head start. Could you keep such a group secret, and when the rest of the network releasises your 12 block streak, the currencies value will plummet or you will very likely be ddosed by angry users of the currency.
Post here if you agree, or we can have a friendly discussion on why the currency isn't secure. If so I am open minded.
