i have no idea what this word means or where you are taking it from but "bitcoin" itself is not hack-able. the way private keys are (a random number in an unbelievably huge range), and how the hashing to get the public keys and bitcoin address (ECDSA and SHA256 which are irreversible) makes it un-hack-able!
your wallet is hack-able though. if you are not careful, use a weak password or have a compromised machine that you use for your wallet.
ps. more than 8 years of being around and not being hacked even once should answer your question though!
I dont think the bitcoin itself is hackable because it can only be access or hacked through your wallet so if you secure your wallet no hacking will happen. Or even if you double up the security of your online wallet it will make the less possibility that it will be hacked by other people. Its just a matter of prevention.
